Glide 是一个 Android 上的图片加载和缓存库，其目的是实现平滑的图片列表滚动效果。 Glide 3.4.0 发布，此版本现已提供下载，包括大量新特性和 bug 修复。此版本最值得关注的是动态 GIFs，可以通过 GifDecoder 来对 GIFs 进行解码，修复了相关的一些小问题，比如渲染和解码通道的问题。 更多内容请看 milestone。 完整改进记录： 新特性 Allow RequestBuilders to be re-used for multiple loads by introducing the .from() and .clone() APIs. These APIs allow users to set options on a request builder once, pass the builder to their adapters, and then start multiple loads with the single builder (#182). // In your Activity/Fragment@Overridepublic void onCreate(Bundle savedInstanceState) { DrawableRequestBuilder requestBuilder = Glide.with(this) .from(String.class) .placeholder(R.drawable.spinner) .centerCrop() .crossFade(); mAdapter = new MyAdapter(requestBuilder); }// In your Adapter@Overridepublic View getView(int position, View convertView, ViewGroupParent parent) { ... mRequestBuilder.load(myUrls.get(position)).into(convertView); } Add a method to GlideBuilder to set a global decode format (#177), see the configuration wiki. Glide.setup(new GlideBuilder(context) .setDecodeFormat(DecodeFormat.ALWAYS_ARGB_8888)); Add a .preload() API to allow preloading media into memory (#169). Glide.with(fragment) .load(url) .preload(width, height); Add a .signature() API to allow users to easily mix in additional data to cache keys, giving users more control over cache invalidation (#178, #179), see the cache invalidation wiki. Glide.with(fragment) .load(url) .signature(new StringSignature("Version1")) .into(view); Add a Glide.preFillBitmapPool() API to allow pre-filling the BitmapPool to avoid jank from allocations after app startup (#93). Glide.get(context) .preFillBitmapPool(new PreFillType.Builder(mySize)); Allow recursive calls to thumbnail() to load an arbitrary number of different sized thumbnails for a single Target (#149). Glide.with(fragment) .load(myUrl) .thumbnail(Glide.with(fragment) .load(myUrl) .override(200, 200) .thumbnail(Glide.with(fragment) .load(myUrl) .override(50, 50))) .into(myView); Allow thumbnail() to load model and data types that are different than those of the parent (#107). Transformations are now only applied once and no longer have to be idempotent (#112). Build/Infrastructure PMD/Findbugs (#164) Jacoco/Coveralls with 85% test coverage (34f797b). Standard import order (f7a6d65). Bugs 修复 性能 Avoid allocating large byte arrays in BufferedInputStream (#225). Use downsampled image size when obtaining Bitmaps from the pool (#224). GIFs Avoid a crash causing race decoding multiple frames with the same GifDecoder (#212). Always use ARGB_8888 to prevent null GIF frames on some versions of Android that don’t support ARGB_4444 (#216). Fix partially decoded GIF frames (appears as grey or transparent noise in frames) (#207, #204). Set a default frame delay for GIFs which do not specify a frame delay, or specify an overly short frame delay (#205). More robust GIF decoding logic, including a fix for decoding only the first few rows of certain GIFs (#203). Allow fade in/cross fade animations by ensuring that the first frame of GIFs is decoded before the GIF is returned (#159). Fix GIFs always appearing transparent pre KitKat (#199). Memory Fix a memory leak when Glide is first called in an Activity (#210). Transformations Fix underdraw in FitCenter causing noise along the sides of certain images (#195). Maintain transparency during bitmap transformations (#156). Caching Fixed Drawables being cached only be integer resource id which can change and/or overlap after subsequent compilations (#172). Uris Fix failure to detect certain types of file Uris (#161). 其他 Fix concurrency bugs resulting in incorrect assertions being thrown when loads were started on multiple threads (#191, #181). Fix BitmapRequestBuilder not setting the decode format on the cache decoder when format() is called (#187). Fix an assertion in ViewTarget related to restarting requests (#167). Fix Glide.with() throwing pre Honeycomb when given non-support Activities (#158). Avoid using Closeable interface when loading ParcelFileDescriptors on 4.1.1 or earlier (#157). Fix an NPE in Bitmap#getAllocationByteCount() due to a framework bug in the initial release of KitKat (#148). Glide 3.4.0 发布，Android 的媒体管理库下载地址
