　　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。

　　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.

1 2	`Glide.setup(new` `GlideBuilder(context)` `.setDecodeFormat(DecodeFormat.ALWAYS_ARGB_8888));`

Add a .preload() API to allow preloading media into memory (#169).

3

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.

4

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).

1 2	`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 whenformat() 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).
