Embodiment
The method and system of a kind of picture loaded and displayed provided by the invention, for making object of the present invention, technical scheme and advantage clearer, clear and definite, referring to accompanying drawing, developing simultaneously, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The method of a kind of picture loaded and displayed that the embodiment of the present invention provides, comprises the following steps:
The first step: model is used for depositing the list of all pictorial information pictures.Described in step 1 specific as follows:
Step 1, obtain each pictorial information and build picture list, be used for depositing all pictorial informations.Comprise: picture name, picture path, photo resolution, picture size etc.
In this example, the picture relating to comprises local picture (being stored in flash, SD card, the medias such as USB flash disk) and network picture.Network picture comprises media picture in the LAN (Local Area Network) that picture that network operator server provides and network neighbor obtain.
Wherein, local pictorial information obtains and comprises: by the scanning of hardware device drivers layer, obtain the pathname of current media medium, then according to picture suffix name (such as .jpg, .png .gif etc.) All Files is scanned, the picture file information scanning is saved in to picture list.
Network picture information acquisition obtains by the following method:
A. the pictorial information that Virtual network operator provides obtains: the interface that application provides by operator obtains pictorial information, and information is kept in picture list.The interface that operator provides is decided through consultation by applying Fang Ji operator side agreement.
B. network neighbor obtains media pictorial information acquisition in LAN (Local Area Network): (network neighbor's detection method is not in this invention scope by network neighbor, to detect interface, therefore do not describe in detail) obtain the network neighbor address (IP) there is shared resource, then scan All Files folder under this address and obtain pictorial information, pictorial information is kept in picture list.
Second step, structure picture load list, build picture display list, build download pictures list (being step 2).
Wherein, step 21, structure picture load list: be used for depositing the callback interface for showing needing after the ID of the picture of loading in picture list downloaded with this picture.
As shown in Figure 1 to Figure 3, when picture loads after thread startup, by this picture, load the ID depositing in list, find pictorial information corresponding in picture list, then according to picture path, obtain object picture; Such as: start most, current screen 10 shows that page is the 1st page, altogether needs to load 2 pages, and the current user's of being shown to is the 1st page, and the 2nd page of next screen 11 as caching page, to guarantee that user checks the fluency of picture speed.If one page shows 15, the so current picture that need to load is 15*2=30 in picture list, and so, this picture loads in list will deposit 0 to 29 according to loading sequence; If current screen Image Display is the 2nd page, the 1st page of a screen on caching page, the 3rd page of next screen, the order that picture loads list is: 15 ~ 29, then 0 ~ 14,30 ~ 44(hypothesis has abundant picture).
The callback interface of the picture providing in list is provided the picture of the embodiment of the present invention, while having downloaded for picture, judges whether picture needs to show and realize the method for Image Display.
Particularly first, the Image ID loading and Image Display list can be contrasted, if this Image ID is not in Image Display list, directly skip over, not load photo current, and ID is shifted out from picture loading list; Secondly, while Loading Image, this picture still needs to show, but needs the time because picture loads, after loading completes, because user's operation, display page changes, and picture does not need to show again, so, should be discharged, allow it no longer show, to guarantee the correctness (this judgement occurs in the picture callback interface of picture loading list definition) of picture browsing.
Step 23, build download pictures list: for depositing the current display screen downloaded and the ID of buffer memory screen shots.Before each pictures is downloaded, judge whether the existing identical picture resource of having downloaded, to reuse resource.
The 3rd step: according to the demonstration needs of screen and the utilization rate of current internal memory, picture is compressed to download when picture is downloaded; Download pictures pictorial information is saved in described picture list after picture application start, picture application builds and shows photo frame according to the picture total quantity in described Image Display list, and need the picture showing to carry out loaded and displayed picture according to the last screen of current display screen and/or a rear screen, exceed the last screen of current display screen and/or the picture of rear screen a needs demonstration does not all load, described in specific as follows
The download of picture is from picture loads list, to obtain Image ID and carry out, if in the process of downloading (picture a has not yet downloaded), user has carried out Image Display switching, no longer show photo current a, but other picture b, after a download finishes, will go to contrast with the pictorial information in Image Display list so, and see and whether still need the picture of demonstration.
Download pictures is to preserve to download successful pictorial information.Because preserve current screen, a upper screen/next screen picture, so switched after a screen, actual is that a upper screen or next screen become current screen.If downloaded on picture the picture of a screen or next screen, just do not needed again to download the effect of this list that Here it is before.Described in specific as follows:
Step 3, be divided into A and two kinds of scenes of B and carry out picture and load the introduction that list and Image Display list load.Other application scenarios only need to design Image Display list and picture loads list, and the principle of work that picture adds carrier thread does not change.
A. every screen need to show multiple thumbnail scenes (photograph album application etc.).
According to picture total quantity, on screen, build the photo frame for Showing Picture, and fill with acquiescence background picture.Revise picture and load list and Image Display list.Set photo current and add up to n, every screen display picture is m, and current page is p, builds screen photo frame to be:
A. when p=1,
As n <=m, need to build m photo frame, and fill acquiescence picture; Image ID 0 ~ m-1 is added to picture and loads list and Image Display list.
As n > m and n > 2*m, need to build 2*m photo frame, and fill acquiescence picture, Image ID 0 ~ 2*m-1 is added to picture and loads list and Image Display list.
As n > m and n <=2*m, need to build n photo frame, and fill acquiescence picture, Image ID 0 ~ n-1 is added to picture and loads list and Image Display list.As shown in Fig. 1 the first half.
B. when having carried out turning over screen, user browses, during p > 1,
When photo current sum n < (p*m), need to build m+(n-(p-1) * m) individual photo frame, and fill acquiescence picture; * m-1 of current screen Image ID (p-1) * m ~ n – 1 and last screen Image ID (p-2) * m ~ (p-1) is added to picture and loads list and Image Display list, as shown in Fig. 3 the first half.
When n > (p*m) and n <=(p+1) * m, need to build 2*m+(n-p * m) individual photo frame, and fill acquiescence picture; The * m-1 of current screen Image ID (p-1) * m ~ p*m – 1, last screen Image ID (p-2) * m ~ (p-1) and a rear screen Image ID p*m ~ n-1 are added to picture and load list and Image Display list.
When n > (p+1) * m, need to build 3*m photo frame, and fill acquiescence picture; * m-1 of * m-1 of current screen Image ID (p-1) * m ~ p*m-1, last screen Image ID (p-2) * m ~ (p-1) and a rear screen Image ID p*m ~ (p+1) is added to picture and loads list and Image Display list.
B. every screen only need to show the application scenarios (Photo Browser, picture browsing etc. in webpage) of a pictures.
Set picture and add up to n, the Image ID of current demonstration is m.
A. when n=1, build a photo frame, fill acquiescence picture.Image ID 0 is added to picture and loads list and Image Display list.
B. when user operates, during n > 1
When m=0, build 2 photo frames, fill acquiescence picture.Image ID 0 and 1 is added to picture and loads list and Image Display list.As shown in Fig. 1 the latter half.
When m>0, build 3 photo frames, fill acquiescence picture.By picture m, m-1 and m+1 are added to picture and load list and Image Display list.As shown in Fig. 2 the latter half.
When m=n-1, build 2 photo frames, fill acquiescence picture.By picture m, m-1 is added to picture and loads list and Image Display list.As shown in Fig. 3 the latter half.
In the present embodiment, it should be noted that, the loading of picture is an asynchronous process, and picture loads list and Image Display list for this Asynchronous loading, so picture adds carrier thread and main thread, is concurrent execution in no particular order; When picture in main thread loads list and Image Display list and changes, picture adds the picture that loads in carrier thread and show and all can dynamically change.
It is when preventing asynchronous download pictures that the picture that builds in the present embodiment loads list and Image Display list, and user's toggle screen makes the picture of downloading not need to show and cause mistake.Download pictures list is to preserve to download complete picture to avoid repeated downloads picture.
By concrete example, picture downloading process of the present invention and Image Display process are described further below:
Wherein, the detailed process that picture is downloaded as shown in Figure 4, specifically comprises:
Whether step S10, lower carrier thread start, and enter step S11 when being, enter step S12 when no.
After step S11, group thread start, judge that sub-thread, whether in waiting status, enters step S13 when being, when no, enter step S14.
Step S12, no startup of carrier thread instantly, control and allow lower carrier thread not start and proceed to step S14.
Step S13, activation, group thread is starting state, but sub-thread is while being waiting status, need again activate sub-thread.All pictures are downloaded complete, so sub-thread waits task next time need activate sub-thread again.
In the present embodiment, create a new sub-thread and namely do not need to judge waiting status.Before whether just need to judging while only having the thread having created to reuse, in waiting status, need to activate and continue to work.
Do you step S14, judge that it is empty that picture loads list? when being, enter step S15, when no, enter step S16.
Step S15, sub-thread waits.In the present embodiment, when picture loading list length is 0, picture adds carrier thread and enters waiting status, waits for user's operation next time.
First object in step S16, delete list, and obtain this ID, proceed to step S17.
Step S17, judge whether to be Image Display list? when no, return to step S14, when being, enter step S18.
Step S18, judge whether to be present in download pictures list? when being, return to S14, when no, enter step S19.
Step S19, by demand technique compresses multiple, and enter step S20.
Step S20, download pictures, and enter step S21.
Step S21, judge whether internal memory overflows, and enters step S22 when being, enters step S23. when no
Step S22, the compression multiple that setting is larger, and return to step S20.Be step S19-22 when needing download pictures, according to the demonstration of screen, need and the utilization rate of current internal memory is compressed download to picture.This kind of compression method of sacrificing picture quality, the amount of ram that former picture is taken becomes the compression of multiple to get off.Such as the picture of a 1200*1200, wide and height all compresses 8 times, and the internal memory taking is so just 1/ (8*8)=1/64 of former figure.Can prevent low memory.
Step S23, download pictures success, and enter step S24.
Step S24, join download pictures list.
In picture downloading process of the present invention, first judge whether to have started picture and add carrier thread, do not start and start; Started and judged that sub-thread, whether in waiting status, if in waiting status, activates; Wherein, the principle of work of sub-thread is: work in the time of in harness, and when not working, have a rest and wait for.
Then judge whether picture loads list is empty, and empty if, picture adds carrier thread and enters waiting status; If it is not empty that picture loads list, continue following operation.
Remove picture and load first object (as the step S16 in figure tetra-) in list, this object is kept in a temporary variable I and (is removed liking in order to guarantee that list has been empty when all objects of picture loading list all judge end).From this variable I, obtain this Image ID as the Image ID of current loading, and remove to judge whether in Image Display list (as the step S17 in figure tetra-).Do not exist, skip and carry out next pictures download; If be present in Image Display list, then entered download pictures list and go to judge that whether this Image ID successfully downloaded (as step S18), if there is the pinup picture success of explanation picture, do not need again to download, skip the download of carrying out next picture.
When picture is downloaded successfully, Image ID is added into download pictures list, from variable I, obtain the call back function of picture, carry out the Graphics Processing of picture; When loading list length, be 0, thread is in waiting status.
In the present embodiment, before picture is downloaded, need to arrange according to picture demand size, when needing download pictures, according to the demonstration needs of screen and the utilization rate of current internal memory, picture be compressed to download.Be that in the present embodiment, to download to picture in internal memory be through the picture of overcompression rather than download former figure and then adjust picture size.Download former figure and adjust size again and can not reduce the amount of ram that picture takies, at least, in the process of download pictures, the occupancy of internal memory is still very high.Such as former figure size 1200*1200, one pictures size of screen display is: 150*100, the wide height of picture can be carried out to equal proportion compression, carry out the compression of 1200/150=8 times, the picture after downloading is the 1/8 original wide * 1/8 former figure size in height=1/64, has saved very most internal memory.If the picture committed memory after the compression of demand size has still exceeded the memory size that system provides (as step S21), then exception catching can be carried out picture to less ratio compression, obtain less picture, when showing, do suitable stretching, to meet the size of the required picture of application.This way is especially obvious to the optimization of internal memory when thumbnail is made.
In the present invention, as shown in Figure 5, Image Display process specifically comprises the following steps Image Display process:
Step S30, user check next screen picture, proceed to step S31.
Step S31, judge whether next screen picture exists, and enters step S32 when no, enters step S33 when being.
Step S32, prompting user, next screen picture does not exist.
Step S33, next screen Image Display are current screen, and proceed to step S34.
Step S34, empty picture and load list and Image Display list, and proceed to step S35.
Whether step S35, the front upper screen picture of tangent screen exist, and enter step S36 when being, enter step S37 when no.
Step S36, in download pictures list, delete this Image ID, and proceed to step S37.
After step S37, tangent screen, whether next screen picture exists, and enters step S38 when being, enters step S39 when no.
Step S38, establishment next screen photo frame, and proceed to step S39.
Step S39, the sub-thread of download pictures, and proceed to step S40.
Step S40, download pictures success, and proceed to step S41.
Step S41, call picture call back function, and proceed to step S42.
Whether step S42, picture in Image Display list, enter step S43 when no, enters step S44 when being.
Step S43, from download pictures list, delete and releasing memory.
Step S44, corresponding photo frame show.
In the present embodiment, when user browses other page of picture, terminal can be according to the last ping buffer picture of user's indicated number or a rear ping buffer picture as current screen picture.Such as: current screen display shows that page is the 3rd page, and left side is the 2nd page, and right side is the 4th page.User need to browse the 2nd page of picture, and screen slides to the right.Now, current page becomes second page, and left side needs new to add the 1st page as caching page, and the 3rd page, right side is as caching page.The 4th page of picture has not been buffer memory screen picture, needs releasing memory.The Image ID sequence of this page, from deleting download pictures list, is discharged to the internal memory that this screen picture takies.Meanwhile empty picture and load list and Image Display list (step S34 as shown in Figure 5), according to foregoing step 3, recalculate picture and load list and Image Display list.
And download successful picture, be invoked at the call back function (step S41 as shown in Figure 5) that picture loads the picture that in list, registration realizes.This function, by list contrasts with Image Display, judges whether this picture is to Show Picture.If so, show this picture, replace acquiescence picture; Otherwise, discharge the shared internal memory of this picture, and it (is noted: before and after picture obtains from deleting download pictures list, because the time is longer, now user's page turn over operation can cause the variation of Image Display list and loading list, and the picture of downloading can not be released, so there is this judgement).
In the present embodiment, because picture is Asynchronous loading, so picture adds carrier thread (step shown in Fig. 4 and Fig. 5) and main thread, (step 1-> step 3) is concurrent execution in no particular order, when picture in main thread loads list and Image Display list and changes, picture adds the picture that loads in carrier thread and show and all can dynamically change.
Based on above-described embodiment, the present invention also provides a kind of system of picture loaded and displayed, as shown in Figure 6, described system comprises: picture list is set up module 610, pictorial information module 620, picture and downloaded compression module 630, picture load-on module 640, Image Display module 650, download pictures module 660;
Wherein, described picture list is set up module 610 for setting up picture list, for depositing all pictorial informations; Set up picture and load list, for depositing described picture list, need the pictorial information loading; Set up Image Display list, for depositing described picture list, need the pictorial information showing; Set up download pictures list, for depositing the pictorial information of having downloaded;
