Android 圖片加載和緩存庫，Glide 3.5.0 發布

Glide是一個囊括了圖片下載、剪裁、內存和磁盤緩存，以及位圖重用功能于一體的快速高效圖像加載庫，同時也方便了接口的使用。默認情況下，Glide庫在Google Vooley項目的基礎上實現了通過http協議的圖像獲取以及Android并行網絡的操作。

Glide 3.5.0 發布，此版本是增量版本，包括一些新特性和重要的 bug 修復。

新特性

• 添加 GlideModules，更簡單的延遲配置 (#311).

• 支持原始大小 (#274):

// You can override a view's size to request the original image:Glide.with(context)
    .load(myUrl)
    .override(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)
    .into(myImageVIew);// SimpleTarget also now defaults to SIZE_ORIGINAL:Glide.with(context)
    .load(myUrl)
    .into(new SimpleTarget<Bitmap>() {        @Override
        public void onResourceReady(Bitmap bitmap, GlideAnimation animation) {            ...
        }
    });

• 改進 ListPrerloader API, including an interface allowing different sizes per position thanks to @DavidWiesner (#273)

• [ALPHA] AppWidget 和 NotificationTarget實現 thanks to @pavlospt (#242):

AppWidgetTarget widgetTarget = 
        new AppWidgetTarget(context, remoteViews, R.id.view_id, 300, 400, R.id.widget_id);Glide.with(context)
    .asBitmap()
    .load(myUrl)
    .into(widgetTarget);

• Override values are passed through to thumbnails (#236).

• Automatically call trim/clear memory based on ComponentCallbacks (9063f6c).

Build/Infrastructure

• 更新到 Robolectric 2.4 thanks to @TWiStErRob (#249).

• 更新到 Android gradle plugin 1.0+ (ba32d32).

• 添加 Intellij 文件，開發更方便 (e34df44)

Bugs 修復

性能

• Fixed needlessly copying Bitmaps decoded from data without an EXIF orientation tag (#270).

• Freed thumbnails eagerly when full loads finish (#237).

• Fixed a strict mode violation initializing the disk cache on Lollipop (#298).

• Fixed a NetworkOnMainThread exception in the OkHttp integration library (#257)

• Calculate sample size correctly thanks to @jisung (#288)

Rendering

• Worked around a framework issue in KitKat and Lollipop causing certain types of Bitmaps to render old data (#301).

• Fixed large BMPs failing to render (#283).

• Fixed decode failure for images with minimal EXIF segments (#286).

• Fixed a bug causing shared color filters (#276).

其他

• Fixed a crash when the Glide singleton is instantiated on a background thread (#295).

• Fixed a crash when completing loads started or cancelled other loads (#303).

• Fixed skipMemoryCache not always skipping the memory cache (#258).

示例代碼：

// For a simple view:
@Override
public void onCreate(Bundle savedInstanceState) {
    ...
 
    ImageView imageView = (ImageView) findViewById(R.id.my_image_view);
 
    Glide.with(this).load("http://goo.gl/h8qOq7").into(imageView);
}
 
// For a list:
@Override
public View getView(int position, View recycled, ViewGroup container) {
    final ImageView myImageView;
    if (recycled == null) {
        myImageView = (ImageView) inflater.inflate(R.layout.my_image_view,
                container, false);
    } else {
        myImageView = (ImageView) recycled;
    }
 
    String url = myUrls.get(position);
 
    Glide.with(myFragment)
        .load(url)
        .centerCrop()
        .placeholder(R.drawable.loading_spinner)
        .crossFade()
        .into(myImageView);
 
    return myImageView;
}
