) { final AbsListView absListView = (AbsListView) view; return absListView.getChildCount () > 0 && (absListView.getFirstVisiblePosition() > 0 || absListView.getChildAt 讲道理,如果传入的参数View就是AbsListView的话,是不会出现滑动冲突的。那我们排查的重点就先放在排查参数View上,打印view的地址果然看不到一点AbsListView的影子。 ) { final AbsListView absListView = (AbsListView) realView; return absListView.getChildCount ) { final AbsListView absListView = (AbsListView) realView;

    Android中动态更新ListView

    其中OnScrollListener接口需要实现如下两个方法: onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount firstVisibleItem 可视的第一个列表项的索引 visibleItemCount 可视的列表项个数 totalItemCount 总共的列表项个数 onScrollStateChanged(AbsListView () 44 { 45 @Override 46 public void onScrollStateChanged(AbsListView layoutParams = new AbsListView.LayoutParams 133 (AbsListView.LayoutParams.FILL_PARENT, 134 AbsListView.LayoutParams.WRAP_CONTENT

    实习入职第二十天:从setRecyclerListener看listView回收机制

    包容类:AbsListView public static interface AbsListView.RecyclerListener A RecyclerListener is used to receive 这个监听器是用来释放 与该view(放进垃圾堆里面的view,在listView里面就是item视图)  相关的资源 另请参见:AbsListView.RecycleBin, AbsListView.setRecyclerListener 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

    初识ListView

    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
