Specific embodiment
A kind of method and system of picture loaded and displayed provided by the invention, for make the purpose of the present invention, technical solution and
Advantage is clearer, clear, and the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that herein
Described specific embodiment is only used to explain the present invention, is not intended to limit the present invention.
A kind of method of picture loaded and displayed provided in an embodiment of the present invention, comprising the following steps:
Step 1: initially setting up for storing all pictorial information picture lists.Described in step 1 specific as follows:
Step 1 obtains each pictorial information building picture list, is used to store all pictorial informations.It include: picture name
Claim, picture path, photo resolution, picture size etc..
In this example, the picture being related to includes local picture (being stored in flash, SD card, the media mediums such as USB flash disk) and network
Picture.Network picture includes media medium figure in the picture that network operator server provides and the local area network of network neighbor's acquisition
Piece.
Wherein, local pictorial information acquisition includes: to obtain current media medium by the scanning of hardware device drivers layer
Then pathname is scanned All Files according to picture suffix name (such as .jpg .png .gif etc.), by what is scanned
Picture file information preservation is to picture list.
Network picture information acquisition is prepared by the following:
A. the pictorial information that network operator provides obtains: application obtains pictorial information by the interface that operator provides,
By information preservation in picture list.The interface that operator provides is decided through consultation by application side and operator side's agreement.
B. network neighbor obtains media medium pictorial information in local area network and obtains: it is (online to detect interface by network neighbor
Neighbor detection method is not described in detail not in the invention scope) the network neighbor address (IP) for having shared resource is obtained, then sweep
It retouches All Files folder under the address and obtains pictorial information, pictorial information is stored in picture list.
Second step, building picture load list, and building picture shows list, constructs (the i.e. step 2) of download pictures list.
Wherein, step 21, building picture load list: be used to store the ID needed picture to be loaded in picture list and
The callback interface for display after the completion of picture downloading.
As shown in Figure 1 to Figure 3, after picture load thread starting, the ID stored in list is loaded by the picture, is found
Then corresponding pictorial information in picture list obtains object picture according to picture path；Such as: most start, current screen 10
It shows that page is page 1, needs to load page 2 in total, be currently displayed to user is page 1, and page 2 of next screen 11 is as caching
Page, to guarantee that user checks the fluency of picture speed.If one page shows 15, currently need picture to be loaded for figure
15*2=30 in piece list, then, this picture, which loads in list, to store 0 to 29 according to loading sequence；If worked as
Preceding screen picture is shown as page 2, then a screen page 1 on caching page, and next screen page 3, picture loads the sequence of list are as follows: 15~
29, then 0~14,30~44 (assuming that having enough pictures).
The callback interface of the picture provided in the picture load list of the embodiment of the present invention, when being completed for picture downloading,
Judge whether picture needs to show and realize the method that picture is shown.
Step 22, building picture show list: being used to store the ID, Yi Jiyong for needing picture to be shown in picture list
To judge currently to load whether the picture in list needs to load or show.
Specifically it is possible, firstly, to the Image ID loaded and picture be shown that list compares, if the Image ID
It does not show in list, then directly skips in picture, be not loaded with current image, and ID is removed from picture load list；Secondly, plus
When carrying picture, the picture still need it is to be shown, but because picture load needs the time, after loading is complete, because of user
Operation, the display page have changed, and picture does not need to show again, so, it should be discharged, it is allowed no longer to show, to protect
Demonstrate,prove the correctness of picture browsing (judgement occurs in the picture callback interface that picture load list defines).
Step 23, building download pictures list: for storing the current display screen downloaded and caching screen map
The ID of piece.Before the downloading of each picture, judge whether have the identical picture resource downloaded, to reuse resource.
Step 3: display when picture is downloaded according to screen needs and the utilization rate of current memory compresses picture
Downloading；Picture using download pictures after starting and saves pictorial information into the picture list, and picture is applied according to
Picture shows that the picture total quantity in list carries out building display photo frame, and according to the previous screen of current display screen and/or latter
Screen needs picture to be shown to carry out loaded and displayed picture, and previous screen and/or latter screen beyond current display screen need to be shown
Picture is not loaded with, described in detail below,
The downloading of picture is to obtain Image ID from picture load list and carry out, if (figure during downloading
Piece a not yet downloads completion), user has carried out picture display switching, i.e., no longer show current image a, but other picture b, that
Whether it is necessary to go to show that the pictorial information in list compares with picture after a downloading, seeing still need to be to be shown
Picture.
Download pictures are then to save to have downloaded successful pictorial information.Because saving current screen, a upper screen/next
Shield picture, so a really upper screen or next screen become current screen after switching a screen.If downloaded before
The picture of a screen or next screen on picture, there is no need to re-download, here it is the effects of this list.It is described in detail below:
Step 3 is divided into the introduction that two kinds of scenes of A and B carry out picture load list and picture display list load.It is other to answer
It only needs to design picture with scene and shows list and picture load list, the working principle of picture load sub thread does not become
Change.
A. every screen needs to show multiple thumbnail scenes (photograph album application etc.).
The photo frame for showing picture is constructed on the screen according to picture total quantity, and is filled out with default background picture
It fills.It modifies picture load list and picture shows list.Current image sum is set as n, every screen shows that picture is m, currently
Page is p, then constructs screen photo frame are as follows:
A. as p=1,
As n≤m, then need to construct m photo frame, and fill default picture；0~m-1 of Image ID is added to picture to add
It lists table and picture shows list.
Work as n > m and n > 2*m, then need to construct 2*m photo frame, and fill default picture, 0~2*m-1 of Image ID is added
List is loaded into picture and picture shows list.
Work as n > m and n≤2*m, then need to construct n photo frame, and fill default picture, 0~n-1 of Image ID is added to
Picture loads list and picture shows list.As shown in Fig. 1 top half.
B. when user turn over screen browsing, when p > 1,
As current image sum n < (p*m), then need to construct m+ (n- (p-1) * m) a photo frame, and fill default picture；
Image ID (p-1) * m~n -1 and previous screen Image ID (p-2) * m~(p-1) * m-1 will currently be shielded and be added to picture load list
List is shown with picture, as shown in Fig. 3 top half.
As n > (p*m) and n≤(p+1) * m, then need to construct 2*m+ (n-p*m) a photo frame, and fill default picture；
Image ID (p-1) * m~p*m -1, previous screen Image ID (p-2) * m~(p-1) * m-1 and latter screen Image ID p*m will currently be shielded
~n-1 is added to picture load list and picture shows list.
As n > (p+1) * m, then need to construct 3*m photo frame, and fill default picture；Image ID (p-1) * will currently be shielded
M~p*m-1, previous screen Image ID (p-2) * m~(p-1) * m-1 and latter screen Image ID p*m~(p+1) * m-1 are added to figure
Piece loads list and picture shows list.
B. every screen only needs to show the application scenarios (Photo Browser, picture browsing etc. in webpage) of a picture.
Picture sum is set as n, the Image ID currently shown is m.
A. as n=1, a photo frame, filling default picture are constructed.Image ID 0 is added to picture load list and figure
Piece shows list.
B. when user is operated, when n > 1
As m=0,2 photo frames, filling default picture are constructed.Image ID 0 and 1 is added to picture load list and figure
Piece shows list.As shown in the lower half portion Fig. 1.
As m > 0,3 photo frames, filling default picture are constructed.By picture m, m-1 and m+1 be added to picture load list and
Picture shows list.As shown in the lower half portion Fig. 2.
As m=n-1,2 photo frames, filling default picture are constructed.Picture m, m-1 are added to picture load list and figure
Piece shows list.As shown in the lower half portion Fig. 3.
In the present embodiment, it should be noted that the load of picture is an asynchronous process, and picture loads list and picture
Display list is for this asynchronous load, so picture load sub thread and main thread concurrently execute in no particular order；
When picture in main thread loads list and picture display list change, picture loads the picture for loading and showing in sub thread all
It can dynamic change.
Constructed in the present embodiment picture load list and picture show list be in order to prevent asynchronous download pictures when
It waits, user switches screen and the picture of downloading is made not needed to show and cause mistake.Download pictures list is to save downloading
The picture finished is to avoid repeated downloads picture.
Process, which is described further, to be shown to picture downloading process of the invention and picture below by way of specific example:
Wherein, the detailed process of picture downloading is as shown in figure 4, specifically include:
Step S10, whether downloading sub thread starts, and S11 is entered step when being, S12 is entered step when no.
Step S11, after sub thread starts, judge whether sub thread is waited for, S13 entered step when being,
S14 is entered step when no.
Step S12, carrier thread does not start instantly, then control allows downloading sub thread not start and be transferred to step S14.
Step S13, it activates, i.e., when sub thread is starting state, but sub thread is wait state, sub-line need to be activated again
Journey.All picture downloadings finish, so sub thread waits task next time, need to activate sub thread again.
A new sub thread is created in the present embodiment not need namely to judge wait state.Only create
It just needs to judge whether to be waited for before to need to activate when thread reuses to continue to work.
Step S14, do you judge that picture load list is empty? S15 is entered step when being, S16 is entered step when no.
Step S15, sub thread waits.In the present embodiment when picture load list length be 0 when, picture load sub thread into
Enter wait state, waits the subsequent operation of user.
Step S16, first object in delete list, and the ID is obtained, it is transferred to step S17.
Step S17, judge whether to be that picture shows list? return step S14 when no, S18 is entered step when being.
Step S18, judge whether there is in download pictures list? S14 is returned when being, S19 is entered step when no.
Step S19, technique compresses multiple on demand, and enter step S20.
Step S20, download pictures, and enter step S21.
Step S21, judge whether memory overflows, S22 is entered step when being, S23. is entered step when no
Step S22, bigger compression multiple, and return step S20 are set.That is step S19-22 when needing download pictures,
It is needed according to the display of screen and the utilization rate of current memory carries out compression downloading to picture.A kind of this sacrifice picture quality
Compression method, by original picture occupy amount of ram get off at the compression of multiple.Such as the picture of a 1200*1200, it is wide and
It is high all to compress 8 times, then the memory occupied is just 1/ (8*8)=1/64 of original image.It can prevent low memory.
Step S23, download pictures success, and enter step S24.
Step S24, it is added to download pictures list.
In picture downloading process of the present invention, it is first determined whether picture load sub thread is had been turned on, it is inactive, it is opened
It is dynamic；It has been started up, judges whether sub thread is waited for, activated if being waited for；Wherein, sub-line
The working principle of journey is: working when in harness, rests and wait when work.
Then judge whether picture load list is sky, and if it is sky, picture enters wait state if loading sub thread；Such as
The load list of fruit picture is not empty, the then following operation of continuation.
First object (the step S16 in such as Fig. 4) in picture load list is removed, which is stored in one and is faced
In variations per hour I (removing object is to guarantee that list has been empty at the end of picture load all objects of list all judge).
The Image ID is obtained from variable I as the Image ID currently loaded, and goes to judge whether to show in list in picture (as schemed
Step S17 in 4).Do not exist, then skips and carry out next picture downloading；It shows in list, is entered back into if there is in picture
Download pictures list goes to judge whether the Image ID has been successfully downloaded (such as step S18), if existing illustrate picture
Textures success, does not need to re-download, skips the downloading for carrying out next picture.
When picture is downloaded successfully, Image ID is added into download pictures list, the readjustment of picture is obtained from variable I
Function carries out the display processing of picture；When load list length is 0, thread is waited for.
In the present embodiment, before picture downloading, need to be configured according to picture demand size, when needing download pictures
When, it is needed according to the display of screen and the utilization rate of current memory carries out compression downloading to picture.Downloaded in the present embodiment
Picture into memory is the picture through overcompression rather than then downloading original image adjusts picture size again.Downloading original image adjusts again
Size not can be reduced the amount of ram of picture occupancy, at least during download pictures, the occupancy of memory or very high.
Such as original image size 1200*1200, the picture size that screen is shown are as follows: 150*100, then it can be by the high progress of the width of picture
Equal proportion compression, carries out 1200/150=8 times of compression, that is, the picture after downloading is 1/8 wide * 1/8 original high=1/64 original
Figure size has saved significant portion of memory.If still exceeded by the compressed picture committed memory of demand size
Then picture then can be carried out smaller scale compression by exception catching by the memory size (such as step S21) that system provides,
Smaller picture is obtained, does stretching appropriate when display, to meet the size of the required picture of application.This way is in breviary
The optimization of memory is especially apparent when figure production.
In the present invention, picture show process as shown in figure 5, picture show process specifically includes the following steps:
Step S30, user checks next screen picture, is transferred to step S31.
Step S31, judge that next screen picture whether there is, S32 is entered step when no, S33 is entered step when being.
Step S32, user is prompted, next screen picture is not present.
Step S33, next screen picture is shown as currently shielding, and is transferred to step S34.
Step S34, it empties picture load list and picture shows list, and be transferred to step S35.
Step S35, upper screen picture whether there is before tangent screen, and S36 is entered step when being, S37 is entered step when no.
Step S36, the Image ID is deleted in download pictures list, and is transferred to step S37.
Step S37, next screen picture whether there is after tangent screen, and S38 is entered step when being, S39 is entered step when no.
Step S38, next screen photo frame is created, and is transferred to step S39.
Step S39, download pictures sub thread, and it is transferred to step S40.
Step S40, download pictures success, and it is transferred to step S41.
Step S41, picture call back function is called, and is transferred to step S42.
Step S42, whether picture shows in list in picture, and S43 is entered step when no, S44 is entered step when being.
Step S43, simultaneously releasing memory is deleted from download pictures list.
Step S44, corresponding photo frame is shown.
In the present embodiment, when user browses other pages of pictures, terminal can indicate to show previous ping buffer figure according to user
Piece or latter ping buffer picture are as current screen picture.Such as: current screen display page is page 3, and left side is page 2, and right side is
Page 4.User needs to browse the picture of page 2, then screen slides to the right.At this point, current page becomes second page, left side needs newly to add
Add page 1 as caching page, right side page 3 is used as caching page.The picture of page 4 has not been caching screen picture, needs to discharge interior
It deposits.The Image ID sequence of this page is deleted from download pictures list, discharges the memory of screen picture occupancy.At the same time
It empties picture load list and picture shows list (step S34 as shown in Figure 5), counted again according to step 3 noted earlier
Nomogram piece loads list and picture shows list.
And it downloads successful picture and is invoked at the call back function for registering the picture of realization in picture load list (such as Fig. 5 institute
The step S41 shown).The function passes through and picture shows list comparison, judges whether the picture is to need to show picture.If
It is then to show the picture, replaces default picture；Otherwise, the occupied memory of the picture is discharged, and by it from having downloaded figure
(note: before and after picture acquisition, since the time is longer, the page turn over operation of user will lead to picture and show at this time for deletion in piece list
The variation of list and load list, and the picture downloaded cannot be released, so there is this judgement).
In the present embodiment, because picture is asynchronous load, picture loads sub thread (Fig. 4 and step shown in fig. 5)
(step 1-> step 3) concurrently executes in no particular order, and the picture load list and picture in main thread are shown with main thread
When list changes, is loaded in picture load sub thread and the picture of display all can dynamically change.
