User interface to a large extent determines whether the app is received by users, in order to provide a friendly interface, you need to use the image in the application, Android provides a wealth of image processing capabilities.Simple use of images using Drawable objectsAfter adding drawable resources to Android apps, The system automatically creates an index entry in the R.java file: R.drawable.filename,

I believe we usually do Android applications, how much will be contacted to load pictures asynchronously, or load a large number of pictures of the problem, and load pictures we often encounter many problems, such as the image of the disorder, oom and other issues, for beginners, these problems will be more difficult to solve, So there are a lot of open source image loading framework came into being, more famous is Universal-image-loader, I believe ma

Simple "puzzle" implementation1. Free to display more than one picture, each free to move, rotate, zoom2. JSON-based graphical location parameter storage3. Position parameters can be recorded after manual placement to fileMaybe:1. Add a gradient animation when switching graphics positions2. The current input is an absolute number of parameters, no relative to the width of the mobile phone, the latter is intact...Welcome to join us to enrich some inter

Android Common picture-loading framework Picture loading involves the caching of pictures, the processing of pictures, the display of pictures and so on. And with the mobile phone equipment on the market, the rapid development of hardware, the picture of the demand for more and more high, a little processing will caus

Previous "Android" read all the pictures on the SDcard card and show that the reading process has a progress bar display (click the Open link) test on the real machine is very problematic, often encountered memory overflow, the situation of the card dead. Because of the memory on the real machine now, 2G has rarely seen, basically all 8G look like. This app is unfriendly because it puts the read-out image on the app one at a time and does not read the

Compression Reason:1.imageview size If it is 200*300 then loading a 2000*3000 picture into memory is obviously a waste of shameful behavior;2. The most important thing is that when the picture is too large, loading the original image directly causes an Oom exception (out of memory overflow)So generally for large graphs we need to do the compression processingAuthoritative handling methods refer to the big
