[0014] The drawings described herein are used to provide a further understanding of the present application, form a part of the present application, and the illustrative embodiments and descriptions thereof of the present application are used to explain the present application and do not constitute an improper limitation to the present application. In the drawings: Figure 1 It is a flowchart of a screen adaptation implementation method for a terminal device provided by an embodiment of the present application; Figure 2Schematic diagram of the structure of a screen adaptation implementation device for a terminal device provided by an embodiment of the present application. Detailed implementation manners

[0015] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0016] The following will detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0017] As Figure 1 shown, a screen adaptation implementation method for a terminal device provided by an embodiment of the present application includes: S101: Determine the application component information to be loaded into the terminal device; wherein, the application component information includes the component size of the application component, and the component size is defined according to density-independent pixels.

[0018] An application component is the basic unit that constitutes the user interface of a terminal application, and includes visual elements such as buttons, text boxes, image views, list views, etc. When an application component adapts to different screens, it is first necessary to determine the application component information to be loaded on the terminal device, and this application component information is used to determine the size attributes of the application component. The application component information includes the component size of the application component, and the component size is defined according to density-independent pixels. Setting the size of the component according to density-independent pixels (dp), regardless of the pixel density of the terminal device, the visual size of the application component on the screen is basically the same. Compared with directly using the pixel (px) unit, the dp unit can effectively avoid display problems caused by differences in screen pixel density.

[0019] When a user starts an application on a terminal device, the application program first reads the screen parameter information of the device to obtain the screen size, resolution and pixel density of the current device. Based on the generated component configuration file, using the unit conversion mechanism provided by the operating system, the component size parameter in dp units is converted into the physical pixel size applicable to the current device. Through this dynamic conversion process, it is ensured that the application component can be rendered in the correct size and layout on different terminal devices, effectively solving the compatibility problems existing in traditional adaptation solutions and achieving a consistent display effect of the application interface in a multi-device environment.

[0020] S102: Determine the target screen parameters corresponding to the terminal device, and load the target layout file corresponding to the application component according to the target screen parameters.

[0021] Different terminal devices have different corresponding screen parameters, and the screen parameters at least include screen size, resolution, and pixel density. When an application component is displayed, it needs to adapt to different screen parameters. During the development stage of an application, when facing different models of terminal devices, if the adaptation code is repeatedly written for different screen specifications, the development efficiency is relatively low. In the embodiments of the present application, layout files are designed for different specifications of terminal devices. By uniformly calling the layout files and utilizing the layout dependency relationships set in the layout files, the layout relationships between application components can be flexibly adjusted, reducing the repetitive adaptation limitations brought by traditional hard coding. Therefore, after the information of the application components that need to be adapted is determined, it is necessary to determine the target screen parameters corresponding to the currently used terminal device, and then, according to the target screen parameters, select the target layout file corresponding to the application component from the already designed layout files. It should be noted that the layout files are classified and designed according to the resolution. When selecting the target layout file, it is necessary to load the corresponding layout resources according to the resolution of the terminal device.

[0022] In one embodiment, before loading the target layout file, it is necessary to configure the layout file so that when laying out the application components, the appropriate layout file can be directly selected according to the used terminal device, without the need to perform hard coding for each model of terminal device. Just select the appropriate layout file according to the resolution to achieve the screen adaptation of the application components on different terminal devices, effectively reducing the development efficiency.

[0023] Before configuring the layout file, it is first necessary to perform a systematic screen parameter collection work on the target terminal device. According to the preset collection interval, collect the screen parameters corresponding to the terminal devices of different device models from the preset device data sources. Here, the device data sources include data sources such as the official websites of device manufacturers, electronic product evaluation websites, and public device databases. The collected screen parameters include screen size, screen resolution, and pixel density. According to the collected screen parameters, construct a screen information database corresponding to the terminal device. This database serves as the basic data support for subsequent adaptation work and provides an accurate technical basis for formulating adaptation strategies.

[0024] After the construction of the screen information database is completed, the layout file needs to be configured. When configuring the layout file, the absolute layout method is no longer used. Instead, for terminal devices with different screen parameters, the corresponding layout dependency relationship of the terminal device is determined. Among them, the layout dependency relationship is relative layout dependency or constraint layout dependency. The relative layout dependency determines the position of components by defining the relative positions between components. For example, a certain component is located above, below, to the left, or to the right of another component, etc. The constraint layout dependency sets the constraint conditions between components and the parent container or other components, such as a fixed distance from the boundary, an alignment relationship with other components, etc. Through different layout dependency relationships, the component layout can be controlled more flexibly to adapt to changes in different screen sizes and resolutions. After determining the layout dependency relationship, according to the selected layout dependency relationship, the layout dependency relationship between application components is written according to specific syntax and format to generate the corresponding layout file.

[0025] In one embodiment, when generating the layout file, although the layout dependency relationship can achieve layout adaptation of the application interface on different terminal devices to a certain extent, the traditional fixed-value layout method still has limitations. The screen sizes and resolutions of different terminal devices vary greatly. Even if relative layout or constraint layout is used, the fixed-value layout settings are difficult to ensure that the application can present a perfect layout effect on all devices. For example, the appropriate size and position set on a small-screen device may appear too small or in the wrong position on a large-screen device. The percentage layout library is a tool library specifically used to implement the layout of the application interface according to the screen ratio. With the help of this library, the application can dynamically adjust the component layout according to the actual size of the screens of different terminal devices to ensure that the interface can maintain good visual proportions and coordination under various screen sizes, effectively improving the adaptability and user experience of the application. Therefore, after the layout file is constructed, by adding the percentage layout library dependency and setting the percentage layout attributes, the application layout is further optimized to solve the problem of imperfect layout adaptation under different screen sizes and improve the display effect and user experience of the application on various terminal devices.

[0026] In the Android Studio development environment, in order to be able to use the functions of the percentage layout library, it is necessary to add a dependency on the percentage layout library in the configuration file corresponding to the layout project of the terminal device. The configuration file, that is, the build.gradle file, is used to record various resources and dependency relationship information required by the project and is an important configuration basis for the construction and operation of the application project. By adding the dependency, the application project can obtain and use the functions provided by the percentage layout library during the construction and operation process for subsequent percentage layout.

[0027] After adding the dependency of the percentage layout library, it is also necessary to modify the layout attributes in the constructed layout file and convert them into percentage layout attributes. The percentage layout attributes include layout_widthPercent, layout_heightPercent, etc. By setting the layout attributes as percentage layout attributes, when the application runs, it will automatically calculate and adjust the specific positions and sizes of each application component according to the actual size of the terminal device screen and in combination with the functions of the percentage layout library, effectively solving the problem of inconsistent layouts under different screen sizes and ensuring that the application interface can present a good display effect on various terminal devices.

[0028] In one embodiment, there is a serious problem of screen parameter fragmentation in the terminal device market. For devices of different brands and models, their screen resolutions, sizes, and pixel densities vary greatly. If separate adaptation development is carried out for the screen parameters of each device, it will not only greatly increase the development cost but also lead to chaotic resource management and problems such as file redundancy. Therefore, after constructing the layout file corresponding to the terminal device according to the layout dependency relationship, it is necessary to group devices with similar resolutions into one category through device clustering to achieve an adaptation mode where each category of devices is adapted to one category of resources. Thus, when calling the layout file later, only by clarifying which category of device the terminal device belongs to can the corresponding layout file be obtained, effectively reducing repetitive development work and improving the adaptation efficiency.

[0029] Specifically, obtain the screen parameters from the screen information database, and then use a machine learning library in Python, such as Scikit-learn, to perform clustering analysis on different terminal devices corresponding to each screen parameter according to the resolution. Specifically, the K-Means clustering algorithm can be used to divide the terminal devices into several device categories, such as low-resolution devices, medium-resolution devices, high-resolution devices, etc. After completing the device clustering, in order to enable the application to automatically load the appropriate layout file according to the device category during runtime, effective physical storage management of the layout file is required. Therefore, in the resource directory corresponding to the layout project, that is, the res directory, create corresponding resource folders according to the divided device categories. For example, if the device categories are divided into low-resolution category, medium-resolution category, and high-resolution category, then create folders such as layout - sw480p, layout - sw720p, layout - sw1080p, etc. Then, put the previously constructed layout files into the corresponding folders according to the device categories.

[0030] In one embodiment, when the application runs on the terminal device, the server automatically obtains the target screen parameters of the terminal device, matches the corresponding target device category according to the target screen parameters, and then obtains the target layout file corresponding to the target device category from the resource directory according to the reference path of the resource folder. By loading the target layout file, the precise adaptation of the application program interface layout to the device screen parameters is achieved. Through the mapping relationship between the device category and the layout resources, the application can quickly and accurately find and use the adaptation resources, avoiding complex real-time calculations, improving the adaptation efficiency and stability of the application, and also facilitating subsequent resource maintenance and updates.

[0031] S103: Determine the position attribute of the application component according to the layout dependency set in the target layout file.

[0032] After loading the target layout file through the above steps, the target layout file is parsed to extract the layout dependencies set therein. According to the relative layout dependencies or constraint layout dependencies obtained by parsing, combined with the screen parameters of the terminal device, the position attribute of each application component is determined. The position attribute is used to describe the specific coordinate position of the application component on the screen.

[0033] Specifically, determine whether the layout dependency set in the target layout file is a relative layout dependency or a constraint layout dependency. In the case where the layout dependency is a relative layout dependency, determine the position attribute of the application component according to the relative positions between the application components. Extract the relative position descriptions between the application components from the layout file. For example, button A is located above text box B, with a distance of 10 dp. Starting from a certain reference component, combined with the screen parameters of the terminal device, gradually deduce and calculate to determine the position attributes of other components. During the calculation process, it is necessary to convert the distance in dp to the actual physical pixel value.

[0034] In the case where the layout dependency is a constraint layout dependency, determine the position attribute of the application component according to the constraint relationships between the application components. Obtain all the constraint conditions regarding the application components from the layout file. For example, text box E is 15 dp away from the top boundary of the parent container, and button F is horizontally centered with image view G. According to the screen parameters of the terminal device, perform comprehensive calculations in combination with these constraint conditions.

[0035] It should be noted that the calculation process needs to consider the mutual influence among multiple constraint conditions simultaneously. When the position of a component is subject to multiple alignment and distance constraints, it is necessary to find the coordinate values that satisfy all the constraint conditions through mathematical calculations and logical reasoning. Taking the constraint condition that the distance between Picture C and the left boundary of the parent container is 20 dp and it is aligned with the right boundary of Button D as an example, first, determine the starting position of Picture C in the horizontal direction according to the width of the parent container and the distance requirement of 20 dp. Then, further accurately determine the ending position of Picture C in the horizontal direction by obtaining the right boundary coordinates of Button D, so as to completely determine its horizontal position attribute. In the vertical direction, calculations are also carried out based on the relevant constraint conditions. In this way, the complex constraint relationships in the constraint layout file are transformed into specific position coordinates to achieve the precise positioning of application components on the screen.

[0036] S104: Based on the position attribute and the component size, display the application component on the screen of the terminal device to achieve the adaptation of the application component among terminal devices with different screen parameters.

[0037] After determining the position attribute and component size of the application component, it is necessary to display the application component on the screens of terminal devices with different screen parameters based on the position attribute and component size, so as to achieve the adaptation of the same application on the screens of different terminal devices. It should be noted that since the position attribute and component size mentioned above are both defined based on dp, and in actual display, they need to be converted into physical pixel values that can be recognized by the terminal device. Therefore, when displaying the application component on the screen, it is also necessary to perform unit conversion on the position attribute and component size of the application component according to the screen situation of the current device.

[0038] In one embodiment, for some special terminal devices, such as foldable screen devices, it is impossible to adapt to the dynamic adjustment of the visible area after the screen state change of the foldable screen device only based on fixed screen parameters and position attributes. If the application cannot be adapted and displayed according to the screen folding state, problems such as incomplete display of components and layout disorders may occur. For example, when the device switches from the unfolded state to the folded state, the application components that were originally normally displayed on the full screen may be blocked or displayed abnormally due to the smaller visible area.

[0039] Specifically, sensors such as angle sensors and Hall sensors set on the terminal device are required to detect the screen folding state of the terminal device in real time. The angle sensor can measure the folding angle of the screen, while the Hall sensor can detect whether the screen is in a closed state. After obtaining the screen folding state, determine the visible area of the terminal device in this state. Specifically, it can be calculated based on the current folding angle and the screen size. After clarifying the visible area, according to the previously determined position attributes and component sizes of the application components, combined with the range of the current visible area, adjust and layout the display of the components. First, it is necessary to determine whether the application component is within the visible area based on its position attributes. If part or all of the application component exceeds the visible area, the position of the application component needs to be adjusted according to certain rules. For example, move the exceeded part back into the visible area, or scale the application component according to the size of the visible area. For the component size, ensure that the component is displayed in an appropriate size within the visible area according to the size and proportion of the visible area. Then, during the display process, it is necessary to monitor the change of the screen folding state in real time. Once the screen state change is detected, the above process will be executed again to determine the visible area and adjust the component display again, so as to achieve the dynamic adaptation and smooth display of the application components in different usage states of the folding screen device. Determining the visible area through the screen folding state and combining the position attributes and sizes of the application components for display effectively solves the problem of application adaptation for folding screen devices, provides a stable and high-quality application experience for users in different usage scenarios, and also provides strong support for the development of applications in the folding screen device market.
