包容类：AbsListView public static interface AbsListView.RecyclerListener A RecyclerListener is used...重要的类有三个：Listview、AbsListView、AdapterView。...图中可以看出重要的类有三个：Listview、AbsListView、AdapterView。主要的回收类RecycleBin位于AbsListView中。...RecycleBin类解析 位于AbsListView中，6466-6900行。 AbsListView的源码中可以看到有个RecycleBin 对象mRecycler。...（6902）该方法属于AbsListView。

从上图可以看出，AdapterView派生了三个子类：AbsListView、AbsSpinner 和 AdapterView Animator，这三个子类依然是抽象的，实际使用时往往采用它们的子类。...其中AbsListView提供的常用XML属性及相关方法如下表所示。 XML属性 相关方法 说明 android:choiceMode 设置 AbsListView 的选择行为。...header View 之后绘制分割条 android:stackFromBottom 设置是否从底端开始排列列表项 android:textFilterEnabled 设置是否对列表项进行过滤，当该 AbsListView...这是默认值 normal : 当该 AbsListView 收到数据改变通知，且最后一个列表项可见时，该 AbsListView 将会滚动到底端 alwaysScroll : 该 AbsListView
mSwipeListView.setOnScrollListener(new OnScrollListener() { @Overridepublic void onScrollStateChanged(AbsListView...mPosition = arg0.getFirstVisiblePosition(); } } @Overridepublic void onScroll(AbsListView
如代码所示 lv_home.setOnScrollListener(new AbsListView.OnScrollListener() { private int scrollState...; @Override public void onScrollStateChanged(AbsListView view, int scrollState...this.scrollState = scrollState; } @Override public void onScroll(AbsListView...int visibleItemCount, int totalItemCount) { if (scrollState == AbsListView.OnScrollListener.SCROLL_STATE_IDLE
效果图： 这里面需要注意一点是 这个按钮加一个判断，当可见区域超过一屏时候显示此按钮 否则隐藏 判断逻辑代码： mListRefreshView.setOnScrollListener(new AbsListView.OnScrollListener...() { @Override public void onScrollStateChanged(AbsListView view, int scrollState...) { } @Override public void onScroll(AbsListView view, int firstVisibleItem
（Android已经预先定义了一些场景所需要的接口和基类如BaseAdapter,ArrayAdapter等） AbsListView 作为ListView和GridView的父类，AbsListView...也就是说ListView和GridView使用的是同一种View复用机制，该机制主要是由两者的父类AbsListView中的内部类RecycleBin完成。...注：以下源码来自android-6.0.0_r5 AbsListView$RecycleBin /** *RecycleBin有助于在布局中重用视图。...Otherwise make some up... // noinspection unchecked AbsListView.LayoutParams p = (AbsListView.LayoutParams...Otherwise make some up... // noinspection unchecked AbsListView.LayoutParams p = (AbsListView.LayoutParams
