Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method and device for browsing pictures. Background Art

[0002] Nowadays, many terminal application apps or websites have embedded picture browsing pages. Picture browsing pages refer to browsing pictures in a way similar to turning pages in an album. In order to display more information on the page, the pictures will be displayed as relatively small thumbnails. When users browse the page, in order to understand the content of the picture more clearly, they need to enlarge the thumbnails. Generally, they click on the thumbnails to trigger the display of the large pictures, and trigger the continuous display of all the large pictures on the page by sliding or clicking. The page for browsing pictures in this way is called a picture browsing page.

[0003] At present, since most image browsing pages do not display too many images, most developers choose to create views equal to the number of images, add images to the created views, and display the images in turn by sliding. When the image data is obtained, according to the number of images to be displayed, the scroll view can be scrolled to complete the browsing of all images by sliding.

[0028] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0029] In order to solve the problems existing in the prior art, the present invention provides a method and device for browsing pictures. When a user browses pictures, the picture view is reused and displayed through a reuse and recycling mechanism, which can greatly save the memory consumption caused by creating the picture view, save memory resources, and make the picture browsing process smoother. In addition, the method for browsing pictures of the present invention can also load pictures adjacent to the current picture in advance when displaying the current picture, such as the previous (prepage) and / or next (nextpage) pictures, by preloading the pictures, so that the picture browsing is smoother, thereby improving the user experience.

[0030] Figure 1 Schematic diagram of the main steps of the method for browsing pictures according to an embodiment of the present invention. Figure 1 As shown, the method for browsing pictures according to the embodiment of the present invention mainly includes the following steps S101 and S102.

[0031] Step S101: when entering the current view page of the picture browsing page, obtaining the picture view from the reuse pool, and loading the picture data of the picture corresponding to the current view page into the picture view for display;

[0032] Step S102: When the current view page is fully displayed, the image view of the previous view page displayed before the current view page is removed and added to the reuse pool.

[0033] According to an embodiment of the present invention, a reuse pool is used to save image views ImageView. Each time a view page needs to be displayed, an available image view is first obtained from the reuse pool, thereby realizing the reuse of image views. There is no need to create an image view for each image to be displayed, thereby greatly saving time and memory resources for creating image views.

[0034] According to an embodiment of the present invention, if the picture view cannot be obtained from the reuse pool, a picture view is created, and the picture data of the picture corresponding to the current view page is loaded into the created picture view for display.

[0035] If the image view cannot be obtained from the reuse pool, it may be because the current view page is the first view page to be displayed after entering the image browsing page, and no image view ImageView has been created at this time. In this case, an image view will be created and the image data of the image corresponding to the current view page will be loaded into the created image view for display.

[0036] According to another embodiment of the present invention, the number of picture views is 2. Since only one large picture is generally displayed at a time when browsing pictures, and at most two pictures are displayed at the same time during view sliding, in order to save unnecessary memory consumption, only two picture views need to be created.

[0037] According to another embodiment of the present invention, when entering the current view page of the picture browsing page, the picture data of the picture corresponding to the current view page and the pictures adjacent to the picture corresponding to the current view page are obtained and cached. By pre-downloading and caching the picture data of the picture corresponding to the current view page and the pictures adjacent to the picture, when the picture data of these pictures are used, they can be directly read from the local cache without downloading again, thereby greatly shortening the time for generating the view page and avoiding the jamming caused by the download occupying the network, making the picture browsing smoother.

[0038] The implementation process of the method for browsing pictures of the present invention is introduced below in conjunction with an embodiment.

[0039] When the user enters the image browsing page by clicking on a thumbnail, first, create two image views ImageView (image view Figure 1 and picture view Figure 2 ), and then obtain the picture data of the current picture and the pictures adjacent to it when entering the picture browsing page according to the storage address path URL of the picture. Among them, in order to determine the adjacent relationship between pictures, the pictures to be displayed on the picture browsing page can be numbered so that each picture has a serial number, and the order between the pictures can be determined according to these serial numbers. For example: assuming that when the user enters the picture browsing page, the serial number of the current picture is M, and the serial numbers of the two pictures adjacent to it are (M-1) and (M+1) respectively, then when downloading the picture data of the picture with serial number M, the picture data of the two pictures with serial numbers (M-1) and (M+1) can be pre-downloaded to the local and cached. When the user slides the page to enter the previous view page or the next view page, the picture data can be directly obtained from the cache according to the URL of the corresponding picture, so that the picture display is smoother.

[0040] After obtaining the image data of the current image, you can load the image data of the current image into any of the created image views to display the current view page. Figure 1 In order to display the current view page, then the picture view Figure 2 That is, as a preloaded image view, when the user slides the page to enter the previous view page or the next view page, the image data of the image corresponding to the previous view page or the next view page can be directly loaded into the image view. Figure 2 The view page can be displayed in , and the display speed is fast.

[0041] In the embodiment of the present invention, the created image view ImageView is a slidable image view. When the slidable image view ImageView slides or scrolls, it can slide or scroll from one view page to another view page. Taking sliding or scrolling from view page 1 to view page 2 as an example, when sliding or scrolling view page 1, the system will determine the sliding or scrolling direction according to the user operation, so as to determine which image is displayed on the view page 2 to be entered. Assuming that view page 1 is displayed through the image view Figure 1 Display image 1, view page 2 through the image view Figure 2 Display Picture 2, where Picture 2 may be the previous picture prepage of Picture 1 or the next picture nextpage of Picture 1. In particular, when Picture 1 is the first picture to be displayed on the picture browsing page, its previous picture prepage is empty; when Picture 1 is the last picture to be displayed on the picture browsing page, its next picture nextpage is empty.

[0042] When sliding or scrolling from view page 1 to view page 2, the previously created image view will be taken out from the reuse pool. Figure 2 , and load image 2 into the image view Figure 2 In order to display the view page 2, the current page of the APP or web page may display part of the view page 1 and part of the view page 2 at the same time, so as to achieve smooth switching during the sliding or scrolling of the view page. After the view page 2 is fully displayed, the previously displayed image of the view page 1 is displayed. Figure 1 Remove and add to the reuse pool.

[0043] When you slide or scroll again to make view page 2 to the view page to be displayed, you will first check whether there is an available image view from the reuse pool. At this time, there is an image view in the reuse pool. Figure 1 and available, then get the image view Figure 1 , and refresh the image view Figure 1 The data can be displayed. Figure 1 When the data is displayed, it can be specifically determined whether the view page to be displayed is the same as view page 1 (that is, whether the user slides to the previous display view page again). If so, the image view is directly taken out. Figure 1 Otherwise, take out the picture and display it. Figure 1 , clear the loaded image 1, and then load the image corresponding to the view page to be displayed into the image view Figure 1In this way, the view page can be displayed with only two image views, without creating image views multiple times, thus saving memory consumption. In addition, when the user slides or scrolls the view page, the next large image to be displayed is one of the previous and next images of the current image. Therefore, each time the user enters a view page, the adjacent images of the image displayed on the entered view page are pre-downloaded and cached in advance, and images are obtained from the cache first for display, making image browsing smoother.
