[0002] With the development of mobile internet technology, in the scene of intelligent device file management, users' demand for file type visualization is increasing. When operating NAS storage, private cloud and other systems, users need to quickly identify different types of files through icons, which puts higher requirements on the flexibility, scalability and performance of the file icon system.

[0003] The traditional file icon management scheme relies on static resource files. File icons are usually designed by designers in advance and introduced into the project as static resources, and are bound to file types through hard coding. This scheme requires product managers and designers to manually plan the mapping relationship of each type of icon. When new file types are added or icon styles are modified, code modification and resource update must be implemented, which has poor flexibility and cannot efficiently cope with the increasing number of file types and personalized display requirements, resulting in significant increase in application development and maintenance costs.

Detailed descriptions follow.

[0029] Example 1 Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for dynamically generating file type icons with extensions, as disclosed in an embodiment of the present invention. Figure 1The described method for dynamically generating file type icons with extensions can be applied to electronic devices with installed applications, where the application has a target interface, and the electronic device is communicatively connected to a network attached storage device (NAS) and accesses the NAS through the application. It can also be applied to devices for dynamically generating file type icons with extensions, which can communicate with the NAS. These devices may include intelligent servers or platforms for generating file type and extension images. The intelligent server may include a NAS server or a cloud server; however, this embodiment of the invention does not limit the scope of the method. Figure 1 As shown, the method for dynamically generating file type icons with extensions can include the following operations: 101. When reading a target file stored on the network-attached storage device through the application, obtain the target file and its file information.

[0030] In this embodiment of the invention, optionally, the target file and its file information can be obtained through a preset setFileIcon extension method. This extension method is an extension function that can be called by any ImageView. The file information of the target file may include path information and attribute information, and may also include information such as the modification time of the target file. This invention does not limit this.

[0031] 102. Determine whether the target file is a directory file based on the file information. If the target file is a directory file, obtain the preset directory icon corresponding to the directory file.

[0032] In this embodiment of the invention, optionally, the target file can be determined to be a directory file based on the file information. When the target file is a directory file, a preset directory icon corresponding to the directory file can be obtained. The preset directory icon may include a folder icon. After obtaining the preset directory icon, the directory icon can be directly displayed in the target interface corresponding to the target file. This invention does not impose any limitations.

[0033] 103. When the target file is not a directory file, extract the file extension of the target file and determine the file type of the target file according to the file extension and the preset file type mapping table.

[0034] In this embodiment of the invention, optionally, when the target file is not a directory file, the file extension of the target file can be extracted. Optionally, after extracting the file extension of the target file, the file extension can be converted to lowercase, and then the file type of the target file can be determined according to the file extension and a preset file type mapping table. That is, the file extension is mapped to the internal type constant of the file type mapping table to determine the file type. The file type of the target file can include special file types or ordinary file types. Special file types can include thumbnail file types or ISO file types. Thumbnail file types can include image / video file types.

[0036] 104. Determine the target key value of the target file based on the file extension and file type.

[0037] In this embodiment of the invention, optionally, after determining the file type of the target file, the target key value of the target file can be determined according to the file extension and file type. The target key value can be used to detect whether there is a target bitmap corresponding to the target key value in the preset cache space, thereby avoiding the repeated creation of bitmaps and the waste of performance and storage space.

[0038] 105. Check if a target bitmap corresponding to the target key exists in the preset cache space. If the target bitmap corresponding to the target key does not exist in the cache space, generate the bitmap corresponding to the target file according to the file extension and file type, and display the bitmap in the target interface.

[0039] In this embodiment of the invention, optionally, the existence of a target bitmap corresponding to a target key value can be detected in a preset cache space. When the target bitmap corresponding to the target key value does not exist in the cache space, a bitmap corresponding to the target file is generated according to the file extension and file type. The bitmap corresponding to the target file may include the file type icon and extension text of the target file, which is not limited in this invention.

[0040] It is evident that implementation Figure 1The described method for dynamically generating file type icons with extensions can, when the application reads a target file stored on the network-attached storage device, obtain the target file and its file information, determine whether the target file is a directory file based on the file information, and if so, obtain a preset directory icon. This method avoids wasting performance and memory resources by directly obtaining the directory icon, thus improving overall efficiency and performance. If the target file is not a directory file, the method extracts the file extension and determines the file type based on the file extension and a preset file type mapping table. It then determines the target key value based on the file extension and file type, and checks whether a corresponding bitmap exists. If the bitmap does not exist, it generates the corresponding bitmap based on the file extension and file type, and displays the bitmap in the target interface corresponding to the target file. This method can generate corresponding icons based on file type and extension, improving the flexibility of file icon generation. Furthermore, it can directly generate icons for new file types without updating application resources, improving the scalability and efficiency of file icon generation.

[0041] In an optional embodiment, the method for dynamically generating file type icons with extensions may further include the following operations: When the target bitmap corresponding to the target key-value exists in the cache space, the target bitmap is displayed in the target interface corresponding to the target file; Furthermore, after generating the bitmap corresponding to the target file based on the file extension and file type, the dynamic generation method for the file type icon with the file extension can also include the following operations: Generate key-value pairs based on the target key and the bitmap, and store the key-value pairs in the cache space.

[0042] In this optional embodiment, after determining the file type of the target file, the target key value of the target file can be determined according to the file extension and file type. The target key value can be used to detect whether there is a target bitmap corresponding to the target key value in the preset cache space. When there is a target bitmap corresponding to the target key value in the cache space, the target bitmap corresponding to the target key value is directly returned and displayed in the target interface corresponding to the target file, avoiding repeated creation of bitmaps and causing waste of performance and storage space. This embodiment does not limit this.

[0043] In this optional embodiment, after generating the bitmap corresponding to the target file based on the file extension and file type, key-value pairs can be generated based on the target key and the bitmap, and then the bitmap can be stored in the cache space in the form of key-value pairs for use by subsequent files of the same type. This embodiment does not limit this.

[0044] As can be seen, implementing this optional embodiment can determine the target key value of the target file based on the file extension and file type, check whether there is a target bitmap corresponding to the target key value in the preset cache space, and display the target bitmap in the target interface corresponding to the target file when the target bitmap corresponding to the target key value exists in the cache space. When the target bitmap corresponding to the target key value does not exist in the cache space, the operation of generating the bitmap corresponding to the target file based on the file extension and file type is triggered. This can avoid the repeated generation of file icons of the same type and extension based on the cache, avoid the memory and performance waste caused by duplicate icons, and improve overall efficiency and performance.

[0045] Example 2 Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for dynamically generating file type icons with extensions, as disclosed in an embodiment of the present invention. Figure 2 The described method for dynamically generating file type icons with extensions can be applied to electronic devices with installed applications, where the application has a target interface, and the electronic device is communicatively connected to a network attached storage device (NAS) and accesses the NAS through the application. It can also be applied to devices for dynamically generating file type icons with extensions, which can communicate with the NAS. These devices may include intelligent servers or platforms for generating file type and extension images. The intelligent server may include a NAS server or a cloud server; however, this embodiment of the invention does not limit the scope of the method. Figure 2 As shown, the method for dynamically generating file type icons with extensions can include the following operations: 201. When reading a target file stored on the network-attached storage device through the application, obtain the target file and its file information.

[0046] 202. Determine whether the target file is a directory file based on the file information. If the target file is a directory file, obtain the preset directory icon corresponding to the directory file.

[0047] 203. When the target file is not a directory file, extract the file extension of the target file and determine the file type of the target file according to the file extension and the preset file type mapping table.

[0048] 204. When the file type includes special file types, load the special file icon corresponding to the target file.

[0049] In this embodiment of the invention, the special file type may optionally include a thumbnail file type or an ISO file type. The thumbnail file type may include an image / video file type. When the file type includes a special file type, the special file icon corresponding to the target file can be directly loaded and displayed. The book file icon includes the thumbnail URL corresponding to the thumbnail file type or the image file icon corresponding to the ISO file type. This invention does not limit the scope of the invention.

[0050] 205. When the file type includes ordinary file types, determine the target key value of the target file based on the file extension and file type.

[0051] 206. Check if the target bitmap corresponding to the target key value exists in the preset cache space. If the target bitmap corresponding to the target key value does not exist in the cache space, generate the file icon corresponding to the target file according to the ordinary file type and file extension, and convert the file icon to the bitmap corresponding to the target file according to the preset bitmap conversion method.

[0052] In this embodiment of the invention, optionally, when the file type includes a regular file type, and a target bitmap corresponding to the target key value is detected in a preset cache space, if the target bitmap corresponding to the target key value is not found in the cache space, a file icon corresponding to the target file can be generated based on the regular file type and file extension. Specifically, a custom view component can be created using the ViewBinding component, which includes an icon and a file tag displaying the file extension. val view = FileIconLayoutBinding.inflate(LayoutInflater.from(CommonAppHelper.getApplication())) Then, the file icon is converted into the bitmap corresponding to the target file according to the preset bitmap conversion method. The preset bitmap conversion method includes the viewToBitmap method, which is not limited in this invention.

[0053] 207. Display the bitmap in the target interface.

[0054] In this embodiment of the invention, for other descriptions of steps 201-203 and step 207, please refer to the detailed description of steps 101-105 in Embodiment 1 of the invention. These descriptions will not be repeated in this embodiment of the invention.

[0055] It is evident that implementation Figure 2The described method for dynamically generating file type icons with extensions can, when the application reads a target file stored on the network-attached storage device, obtain the target file and its file information, determine whether the target file is a directory file based on the file information, and if so, obtain a preset directory icon corresponding to the directory file, thereby improving overall efficiency and performance by directly obtaining the directory icon. If the target file is not a directory file, the method extracts the file extension of the target file and determines the file type of the target file based on the file extension and a preset file type mapping table. If the file type includes special file types, the method loads the special file icon corresponding to the target file, enabling the direct loading of special file types. Specialized file icons (for images, videos, etc.) improve icon display efficiency while avoiding the waste of performance and memory resources caused by repeatedly generating icons, thus improving overall efficiency and performance. When the file type includes ordinary file types, a file icon corresponding to the target file is generated based on the ordinary file type and file extension. The file icon is then converted into a bitmap corresponding to the target file using a preset bitmap conversion method, and the bitmap is displayed in the target interface corresponding to the target file. This feature enables the generation of corresponding icons based on file type and extension, improving the flexibility of file icon generation. Furthermore, when a new file type appears, there is no need to update application resources; the icon corresponding to the file type is generated directly, improving the scalability and efficiency of file icon generation.

[0056] In an optional embodiment, generating a file icon corresponding to the target file based on the common file type and file extension may include the following operations: Based on the common file type and file extension, generate the view component corresponding to the target file. The view component includes an icon and a text label corresponding to the file extension. Retrieve icon configuration information corresponding to ordinary file types from the preset database, configure the icon style according to the icon configuration information, and obtain the configured icon. The icon configuration information includes icon resource information and icon background color information. Determine whether the text label meets the preset text label conditions. If the text label does not meet the text label conditions, adjust the text label to obtain the adjusted text label. Generate the file icon corresponding to the target file based on the configured icon and the adjusted text label.

[0057] In this optional embodiment, a custom view component can be created using the ViewBinding component. This view component includes an icon and text labels corresponding to the file extension. Then, icon configuration information for common file types is retrieved from a preset database. The preset database can store icon configuration information for each common file type, including icon resource information and icon background color information. The icon style is then configured according to the icon configuration information to obtain the configured icon. Specifically, different icons and color schemes can be assigned to different types of files based on the icon configuration information, for example: when (type) { WPS ->{ ivIcon.setImageResource(R.mipmap.file_wps_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_eo3f24) } PDF ->{ ivIcon.setImageResource(R.mipmap.file_pdf_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_eo3f24) } PPT ->{ ivIcon.setImageResource(R.mipmap.file_opt_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_f26e18) } WORD ->{ ivIcon.setImageResource(R.mipmap.file_word_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_0055ff)} BT ->{ ivIcon.setImageResource(R.mipmap.file_bt_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_0055ff) } KEYNOTE ->{ ivIcon.setImageResource(R.mipmap.file_keynote_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_0055ff) } NUMBERS ->{ ivIcon.setImageResource(R.mipmap.file_numbers_icon) tvFileType.background= tvFileType.drawable (R.drawable.shape_r2_bg_24b33c) } } In this optional embodiment, it can be determined whether the text label meets the preset text label conditions. When the text label does not meet the text label conditions, the text label is adjusted to obtain the adjusted text label. The text label conditions may include the text label length condition. Specifically, it can be determined whether the label length corresponding to the text label is greater than or equal to the text label length threshold. When the label length corresponding to the text label is greater than or equal to the text label length threshold, the font of the text label is adjusted, for example, by reducing the font size, to obtain the adjusted text label. This embodiment does not impose any limitations.

[0058] As can be seen, implementing this optional embodiment can generate a view component corresponding to the target file based on the common file type and file extension. The view component includes an icon and a text label corresponding to the file extension. It retrieves icon configuration information corresponding to the common file type from a preset database, configures the icon style according to the icon configuration information, and obtains the configured icon. It can generate icons based on basic icon resources and configure the graphics and colors of the icons according to preset configuration information, improving the efficiency and flexibility of icon generation while ensuring that the generated icons follow a unified design language. It determines whether the text label meets the preset text label conditions. When the text label does not meet the text label conditions, it adjusts the text label to obtain the adjusted text label. Based on the configured icon and the adjusted text label, it generates the file icon corresponding to the target file, enabling the display of the file icon's extension to adopt a unified layout and style, thus improving the user experience.

[0059] In another optional embodiment, converting a file icon into a bitmap corresponding to the target file according to a preset bitmap conversion method may include the following operations: Create a measurement specification corresponding to the file icon, and measure the size information of the file icon according to the measurement specification. The size information includes the first size information of the file icon, the second size information of the icon corresponding to the file icon, and the third size information of the text label of the file extension in the file icon. Determine the relative positions of the icons and text labels within the file icon; Based on the size information and relative position, the file icon is converted into a bitmap corresponding to the target file.

[0060] In this optional embodiment, optionally, measurement specifications corresponding to the text icons can be created, specifically: val measureWidth = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED) val measureHeight = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED) This code creates width and height measurement specifications. The parameter 0 in (0, View.MeasureSpec.UNSPECIFIED) indicates that no exact size value is specified. The code measures the dimensions of the icon in the document according to these specifications. Specifically, the measurement process for the View is triggered by calling `measure(measureWidth, measureHeight)`. This call recursively measures the View and all its child Views, calculating the required actual dimensions. After the measurement is complete, the calculated width and height can be obtained using `measuredWidth` and `measuredHeight`. The size information may include the overall size information of the file icon, and may also include the size information of each component of the file icon. Specifically, the size information may include the first size information of the file icon, the second size information of the icon corresponding to the file icon, and the third size information of the text label of the file extension in the file icon. This embodiment does not limit this.

[0061] In this optional embodiment, the relative positional relationship between the icons and text labels in the file icon can be determined. This relative positional relationship can include the layout relationship between each component of the file icon, such as one or more combinations of top-bottom layout, left-right layout, nested layout, center alignment, and edge alignment. It can also include the alignment method inside the icon, such as one or more combinations of horizontal alignment, vertical alignment, and group alignment. Furthermore, it can include spacing information, such as one or more combinations of inner margin, outer margin, and spacing ratio. It can also include the stacking order, such as one or more combinations of foreground and background, coverage relationship, and transparency control. Based on the size information and relative positional relationship, the file icon is converted into a bitmap corresponding to the target file. This embodiment does not limit this.

[0062] As can be seen, implementing this optional embodiment can create a measurement specification corresponding to the file icon, and measure the size information of the file icon according to the measurement specification. The size information includes the first size information of the file icon, the second size information of the icon corresponding to the file icon, and the third size information of the text label of the file extension in the file icon. The relative positional relationship between the icon and the text label in the file icon is determined. Based on the size information and the relative positional relationship, the file icon is converted into a bitmap corresponding to the target file. Based on the size and layout information of each component in the measured icon, the efficiency of the conversion operation can be improved and the accuracy of the bitmap obtained after conversion can be improved.

[0063] In yet another optional embodiment, converting a file icon into a bitmap corresponding to a target file based on size information and relative positional relationships may include the following operations: Create the target space based on the first dimension information; Based on the second size information, the third size information, and the relative positional relationship, determine the first coordinate information of the icon in the target space and the second coordinate information of the text label in the target space; Based on the first and second coordinate information, the file icon is drawn onto the target space to obtain the bitmap corresponding to the target file.

[0064] In this optional embodiment, a target space can be created based on the first size information. Specifically, a blank Bitmap with the same size as the View can be created using the viewToBitmap method. Then, based on the second size information, the third size information, and the relative positional relationship, the first coordinate information of the icon in the target space and the second coordinate information of the text label in the target space can be determined. For example: layout(0, 0, measuredWidth, measuredHeight) The View is laid out at the specified position and size. The first parameter 0 and the second parameter 00 indicate that the View is placed at the position of coordinates (0,0) (i.e., the top left corner of the blank Bitmap). The third and fourth parameters, measuredWidth and measuredHeight, specify the coordinates of the bottom right corner of the View. Using the measured width and height, the position of all components in the file icon can be determined in the target space using the coordinate information. Then, based on the first and second coordinate information, the file icon is drawn onto the target space to obtain the bitmap corresponding to the target file. Specifically, the View can be drawn onto the Bitmap using a Canvas, but this embodiment does not limit it.

[0065] As can be seen, implementing this optional embodiment can create a target space based on the first size information, determine the first coordinate information of the icon in the target space and the second coordinate information of the text label in the target space based on the second size information, the third size information and the relative positional relationship, draw the file icon into the target space based on the first coordinate information and the second coordinate information, and obtain the bitmap corresponding to the target file. It can draw the bitmap based on the size and layout information of the icon, improve the efficiency of the conversion operation, improve the accuracy of the bitmap obtained after conversion, and at the same time ensure that the icons and extensions in the bitmap follow a unified layout and style, thereby improving the user viewing experience.

[0066] In yet another optional embodiment, the special file type includes a thumbnail file type or an ISO file type; When the file type includes special file types, loading the special file icon corresponding to the target file can include the following operations: When the file type includes thumbnail file type, the preset thumbnail generation interface is called to obtain the thumbnail icon corresponding to the target file; When the file type includes ISO file type, retrieve the preset image icon corresponding to the ISO file type.

[0067] In this optional embodiment, the special file type may include a thumbnail file type or an ISO file type. The thumbnail file type may include an image / video file type. When the file type includes a thumbnail file type, a preset thumbnail generation interface can be called to obtain the thumbnail icon corresponding to the target file. The preset thumbnail generation interface may include getImageThumbnail. The thumbnail icon may include a thumbnail URL. After obtaining the thumbnail icon corresponding to the target file, Glide can be used to load it and directly display the thumbnail icon in the target interface corresponding to the target file. This embodiment does not impose any limitations.

[0068] In this optional embodiment, when the file type includes ISO file type, the preset image icon corresponding to the ISO file type can be directly obtained, and then the preset image icon can be directly displayed in the target interface corresponding to the target file. This embodiment does not limit this.

[0069] As can be seen, implementing this optional embodiment can call the preset thumbnail generation interface to obtain the thumbnail icon corresponding to the target file when the file type includes thumbnail file type, and obtain the preset image icon corresponding to the ISO file type when the file type includes ISO file type. It can directly load the special file icon of special file, improve the icon display efficiency, and avoid the waste of performance and memory resources caused by repeated icon generation, thereby improving the overall efficiency and performance.

[0070] Example 3 Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a dynamic generation device for file type icons with file extensions disclosed in an embodiment of the present invention. Figure 3 The described dynamic file type icon generation device with file extension can communicate with a network attached storage device. This device may include a smart server or smart platform for generating images of file types and extensions. The smart server may be a NAS server or a cloud server; this embodiment of the invention is not limited to this. Figure 3 As shown, a dynamically generated device with a file type icon and extension may include: The acquisition module 301 is used to acquire the target file and its file information, including path information and attribute information, when the target file stored in the network attached storage device is read by the application. The judgment module 302 is used to determine whether the target file is a directory file based on the file information. When the target file is a directory file, the preset directory icon corresponding to the directory file is obtained. The determination module 303 is used to extract the file extension of the target file when the target file is not a directory file, and determine the file type of the target file according to the file extension and a preset file type mapping table; The determination module 303 is also used to determine the target key value of the target file based on the file extension and file type; The detection module 304 is used to detect whether a target bitmap corresponding to a target key value exists in a preset cache space; The generation module 305 is used to generate a bitmap corresponding to the target file based on the file extension and file type when the target bitmap corresponding to the target key value does not exist in the cache space, and to display the bitmap in the target interface.

[0071] It is evident that implementation Figure 3 The described dynamic file type icon generation device with file extension can, when the application reads a target file stored on the network-attached storage device, obtain the target file and its file information, determine whether the target file is a directory file based on the file information, and if the target file is a directory file, obtain a preset directory icon corresponding to the directory file, thereby improving overall efficiency and performance by directly obtaining the directory icon; if the target file is not a directory file, extract the file extension of the target file, determine the file type of the target file based on the file extension and a preset file type mapping table, generate a bitmap corresponding to the target file based on the file extension and file type, and display the bitmap in the target interface corresponding to the target file. It can generate corresponding icons based on file type and extension, improving the flexibility of file icon generation, and when a new file type appears, it does not need to update application resources, directly generating the icon corresponding to the file type, thus improving the scalability and efficiency of file icon generation.

[0072] In an optional embodiment, such as Figure 4 As shown, file types include special file types or ordinary file types; The generation module 305 generates the bitmap corresponding to the target file according to the file extension and file type in the following specific ways: When the file type includes a special file type, load the special file icon corresponding to the target file; When the file type includes ordinary file types, a file icon corresponding to the target file is generated based on the ordinary file type and file extension, and the file icon is converted into the bitmap corresponding to the target file according to the preset bitmap conversion method.

[0073] It is evident that implementation Figure 4The described file type icon dynamic generation device, which generates icons with file extensions, can obtain the target file and its file information when the application reads a target file stored on the network-attached storage device. Based on the file information, it determines whether the target file is a directory file. If the target file is a directory file, it obtains a preset directory icon, improving overall efficiency and performance by directly obtaining the directory icon. If the target file is not a directory file, it extracts the file extension and determines the file type based on the file extension and a preset file type mapping table. If the file type includes special file types, it loads the special file icon corresponding to the target file, enabling direct loading of special file types. Specialized file icons (for images, videos, etc.) improve icon display efficiency while avoiding the waste of performance and memory resources caused by repeatedly generating icons, thus improving overall efficiency and performance. When the file type includes ordinary file types, a file icon corresponding to the target file is generated based on the ordinary file type and file extension. The file icon is then converted into a bitmap corresponding to the target file using a preset bitmap conversion method, and the bitmap is displayed in the target interface corresponding to the target file. This feature enables the generation of corresponding icons based on file type and extension, improving the flexibility of file icon generation. Furthermore, when a new file type appears, there is no need to update application resources; the icon corresponding to the file type is generated directly, improving the scalability and efficiency of file icon generation.

Retrieve icon configuration information corresponding to ordinary file types from the preset database, configure the icon style according to the icon configuration information, and obtain the configured icon. The icon configuration information includes icon resource information and icon background color information. Determine whether the text label meets the preset text label conditions. If the text label does not meet the text label conditions, adjust the text label to obtain the adjusted text label. Generate the file icon corresponding to the target file based on the configured icon and the adjusted text label.

[0075] It is evident that implementation Figure 4The described dynamic file type icon generation device can generate view components corresponding to target files based on common file types and file extensions. These view components include an icon and a text label corresponding to the file extension. The device retrieves icon configuration information for common file types from a preset database, configures the icon style according to this information, and obtains the configured icon. It can generate icons based on basic icon resources and configure the graphics and colors of the icons according to preset configuration information, improving icon generation efficiency and flexibility while ensuring the generated icons adhere to a unified design language. The device also determines whether the text label meets preset text label conditions; if not, it adjusts the text label to obtain an adjusted text label. Finally, based on the configured icon and the adjusted text label, it generates the file icon corresponding to the target file, enabling a unified layout and style for the file icon's extension display, thus enhancing the user experience.

[0076] In yet another alternative embodiment, such as Figure 4 As shown, the specific methods by which the generation module 305 converts the file icon into the bitmap corresponding to the target file according to the preset bitmap conversion method include: Create a measurement specification corresponding to the file icon, and measure the size information of the file icon according to the measurement specification. The size information includes the first size information of the file icon, the second size information of the icon corresponding to the file icon, and the third size information of the text label of the file extension in the file icon. Determine the relative positions of the icons and text labels within the file icon; Based on the size information and relative position, the file icon is converted into a bitmap corresponding to the target file.

[0077] It is evident that implementation Figure 4 The described dynamic file type icon generation device with file extension can create a measurement specification corresponding to the file icon and measure the size information of the file icon according to the measurement specification.

[0079] It is evident that implementation Figure 4 The described dynamic file type icon generation device with extension can create a target space based on first size information, and determine the first coordinate information of the icon and the second coordinate information of the text label in the target space based on second size information, third size information, and relative positional relationships.

It can draw the bitmap based on the size and layout information of the icon, improve the efficiency of the conversion operation, improve the accuracy of the bitmap obtained after conversion, and at the same time ensure that the icon and extension in the bitmap follow a unified layout and style, thereby improving the user viewing experience.

[0080] In yet another alternative embodiment, such as Figure 4 As shown, the dynamic generation device for the file type icon with the file extension may also include: The display module 306 is used to display the target bitmap in the target interface corresponding to the target file when the detection module 304 detects that there is a target bitmap corresponding to the target key value in the cache space; Furthermore, the dynamically generated device for the file type icon with the file extension may also include: The storage module 307 is used to generate key-value pairs based on the target key and the bitmap after the generation module 305 generates the bitmap corresponding to the target file according to the file extension and file type, and then stores the key-value pairs in the cache space.

[0081] It is evident that implementation Figure 4 The described dynamic file type icon generation device with file extension can determine the target key value of the target file based on the file extension and file type. It checks whether the target bitmap corresponding to the target key value exists in a preset cache space. When the target bitmap corresponding to the target key value exists in the cache space, it displays the target bitmap in the target interface corresponding to the target file. When the target bitmap corresponding to the target key value does not exist in the cache space, it triggers the operation of generating the bitmap corresponding to the target file based on the file extension and file type. It can avoid the repeated generation of file icons of the same type and extension based on caching, avoid the memory and performance waste caused by duplicate icons, and improve overall efficiency and performance.

[0082] In yet another alternative embodiment, such as Figure 4As shown, special file types include thumbnail file types or ISO file types; When the file type includes special file types, the generation module 305 loads the special file icon corresponding to the target file in the following ways: When the file type includes thumbnail file type, the preset thumbnail generation interface is called to obtain the thumbnail icon corresponding to the target file; When the file type includes ISO file type, retrieve the preset image icon corresponding to the ISO file type.
