Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
Fig. 1 is a schematic diagram illustrating the rule of loading a page by a conventional ViewPager tool. As shown, assume that five pages v1-v5 are shown, and that five pages may be swiped side-to-side. According to the rule that the ViewPager tool loads the page, the ViewPager tool loads the page v1 firstly and simultaneously preloads the page v 2; when sliding to page v2 (the current load page), continuing to preload page v 3; when sliding to page v3, preload page v4 and remove page v 1; when sliding to page v4, preload page v5, remove page v 2. As can be seen, according to the rule of the ViewPager tool, for the condition that the page number is greater than or equal to four pages, the ViewPager tool needs to operate at least four pages, including loading the current page, preloading the next page, retaining the previous page, and removing the previous page.
Based on the rule that the ViewPager tool loads the page, the optimization method of the carousel image disclosed by the invention is to create at least four ImageView controls for circularly processing at least four images which are sequentially arranged under the condition that the number of the images is more than or equal to four.
FIG. 2 is a schematic diagram of a method according to an embodiment of the present invention. As shown, assuming that one hundred pictures p0-p99 are shown, according to the method of the present invention, four ImageView controls I0, I1, I2, I3 are first created for loop processing the first picture, the second picture, the third picture, and the fourth picture arranged in sequence. In the embodiment of the invention, the second picture is the current loaded picture, the first picture is the previous picture, the third picture is the next picture, and the fourth picture is the preloaded next picture.
As shown, ImageView control I0 loads picture p0, ImageView control I1 loads picture p1, ImageView control I2 loads picture p 2; when the page slides to the picture p2, the ImageView control I3 preloads the picture p3 and removes the ImageView control I0 (the ImageView control I0 is not used for the moment), and at the moment, the ImageView controls I1, I2 and I3 are in an occupied state; when the page slides to a picture p3, deleting a picture p0 of an ImageView control I0 loaded and cached last time, releasing the memory space occupied by the picture p0, preloading the picture p4 by using the ImageView control I0, and removing the ImageView control I1 (the ImageView control I1 is not used for the moment), wherein at the moment, the ImageView controls I2, I3 and I0 are in an occupied state; when the page slides to the picture p4, the picture p1 of the last time the ImageView control I1 loaded the cache is deleted, the memory space occupied by the picture p1 is released, then the picture p5 is preloaded by using the ImageView control I1, and the ImageView control I2 is removed. By analogy, the recycling of the four ImageView controls can be realized by adopting a mode of dividing the subscript of the picture by the remainder of 4; meanwhile, before the ImageView control preloads the next picture, the picture loaded and cached last time is deleted and the memory is released, so that the problem of memory overflow is solved, and the normal carousel display function of multiple pictures can be ensured.
