The present invention in the case where APP needs the scene for loading a large amount of pictures, to outside on-screen display (osd) area
Picture is preloaded, and load complete after picture is cached, so as to user slide the page when,
Quickly displaying picture, improves Consumer's Experience effect.Further, the present invention reaches predetermined value in buffer memory capacity
When, according to picture apart from the distance of viewing area, the picture resource farthest apart from viewing area is first reclaimed, then
The picture resource nearer apart from viewing area is reclaimed, the effective rate of utilization of caching is improved successively.
Below in conjunction with accompanying drawing and embodiment, the present invention will be described in further detail.It should be appreciated that this
The described specific embodiment in place is only used to explain the present invention, does not limit of the invention.
The embodiment of the invention provides a kind of picture loading method.Fig. 1 is figure according to an embodiment of the invention
The flow chart of piece loading method.
Step S110, when the picture in current display area is shown, outside the pre-loaded viewing area
Picture.
Before picture in the display current display area, current display area of the page in screen is obtained
Domain；Judge that the picture in the current display area whether there is in caching；If so, then from the caching
It is middle to obtain the picture and show；If it is not, then load the picture from network side and show, and need by
The picture of loading is cached, can subsequently to reuse the picture.
When picture in the display current display area, in order that the picture that user will browse is quick
Show, the picture outside the pre-loaded viewing area, if buffer memory capacity is limited, can be advance
Loading is outside the viewing area, the picture within preset range.The preset range is located at viewing area
Around, and it is adjacent with viewing area.Include one or more picture in the preset range.
Specifically, preset range is located at viewing area both sides；Or preset range is located at viewing area side.
Preset range can be set according to the capacity of caching, i.e., the active volume according to caching allows to preload
Picture number preset range is set.
Preset range can be weighed with area, it is also possible to be weighed with picture number.For example：Preset range
Area be equal to viewing area area, in other words, preload the previous screen of current display area in the range of
Picture in the range of picture and/or latter screen.And for example：Preset range is the plurality of pictures institute close to viewing area
Scope.When the page is obtained, it is possible to know the position of every pictures in the page, therefore can basis
Which pictures position of the picture among the page is determine needs loading.
If preset range is located at the side of viewing area, the direction that can slide the page according to user determines
The position of preset range.For example：If user's upward sliding page, preset range is located under viewing area
Side；If user's slide downward page, preset range is located at viewing area top.
Step S120, caches the pre-loaded picture.
During user slides the page, constantly caching preloads picture, because the capacity for caching has
The upper limit, so when the caching with capacity when being more than default threshold value, distance is removed in the caching
The farthest picture of current display area.The threshold value is experiment value or empirical value.Cache overflow can be so prevented,
Can also ensure that the picture in the close region of current display area can quickly show.
For example：Fig. 2 is picture loading schematic diagram according to an embodiment of the invention.The page in this example is row
Table page, there is n (n is more than 0) pictures in list page；Picture of the page in on-screen display (osd) area is picture
3rd, picture 4 and picture 5, before display picture 3, picture 4 and picture 5, first determine in caching whether
Picture 3, picture 4 and picture 5 are stored, if stored, with direct access and can have been shown,
If do not stored, Loaded Image from network side and 3, picture 4 and picture 5 and shown, afterwards caching figure
Piece 3, picture 4 and picture 5；Picture 3, picture 4 and picture 5 are removed in the active volume of caching, is remained
Remaining active volume also allow cache 4 pictures, then can determine preset range for viewing area it is outside upper,
Under each two pictures scope, i.e. picture 1, picture 2, picture 6 and picture 7；In display picture 3, figure
During piece 4 and picture 5, picture 1, picture 2, picture 6 and picture 7 are preloaded, and be put into caching
In；User slides page process, if picture 3 removes viewing area, picture 6 enters viewing area, then
Picture 6 is directly obtained from caching and is shown, during display picture 4, picture 5 and picture 6,
Due to picture 7 in the buffer, picture 8 can be preloaded and is cached, by that analogy；If user is again
It is secondary to slide the page to the position of picture 3, picture 4 and the place of picture 5, figure can be obtained from caching again
Piece 3, picture 4 and picture 5 simultaneously show.
It will be appreciated by those skilled in the art that thought of the invention, presumptive area can also be viewing area
The scope of 4 pictures below domain, can also be the scope+viewing area of 1 pictures of viewing area top
