RecycleBin机制是ListView能够实现成百上千条数据都不会OOM最重要的一个原因。RecycleBin是AbsListView的一个内部类。

* RecycleBin当中使用mActiveViews这个数组来存储View，调用这个方法后就会根据传入的参数来将ListView中的指定元素存储到mActiveViews中。
* RecycleBin当中使用mActiveViews这个数组来存储View，调用fillActiveViews()这个方法后就会根据传入的参数来将ListView中的指定元素存储到mActiveViews中。
* mActiveViews当中所存储的View，一旦被获取了之后就会从mActiveViews当中移除，下次获取同样位置的时候将会返回null，所以mActiveViews不能被重复利用。
* addScrapView()用于将一个废弃的View进行缓存，该方法接收一个View参数，当有某个View确定要废弃掉的时候（比如滚动出了屏幕）就应该调用这个方法来对View进行缓存，RecycleBin当中使用mScrapV
* iews和mCurrentScrap这两个List来存储废弃View。
