ViewTarget介绍
[英]A base Target for loading android.graphics.Bitmaps into Views that provides default implementations for most most methods and can determine the size of views using a android.view.ViewTreeObserver.OnDrawListener.
To detect View reuse in android.widget.ListView or any android.view.ViewGroup that reuses views, this class uses the View#setTag(Object) method to store some metadata so that if a view is reused, any previous loads or resources from previous loads can be cancelled or reused.
Any calls to View#setTag(Object)} on a View given to this class will result in excessive allocations and and/or IllegalArgumentExceptions. If you must call View#setTag(Object) on a view, use #setTagId(int) to specify a custom tag for Glide to use.
Subclasses must call super in #onLoadCleared(Drawable)[中]加载android的基本目标。图样将位图映射到视图中，为大多数方法提供默认实现，并可以使用安卓系统确定视图的大小。看法ViewTreeObserver。我是你的听众。检测android中的视图重用。小装置。ListView或任何安卓系统。看法ViewGroup重用视图，该类使用View#setTag（Object）方法存储一些元数据，以便在重用视图时，可以取消或重用以前加载的任何加载或资源。在给定给该类的视图上调用View#setTag（Object）}将导致过度分配和/或IllegalArgumentException。如果必须在视图上调用View#setTag（Object），请使用#setTagId（int）指定Glide要使用的自定义标记。子类必须在#onLoadCleared（Drawable）中调用super

/** * Returns any stored request using {@link android.view.View#getTag()}. * *
For Glide to function correctly, Glide must be the only thing that calls {@link * View#setTag(Object)}. If the tag is cleared or put to another object type, Glide will not be * able to retrieve and cancel previous loads which will not only prevent Glide from reusing * resource, but will also result in incorrect images being loaded and lots of flashing of images * in lists. As a result, this will throw an {@link java.lang.IllegalArgumentException} if {@link * android.view.View#getTag()}} returns a non null object that is not an {@link * com.bumptech.glide.request.Request}.
