怎么获取ListView里Item中的控件

ListView默认情况当item有焦点时，item上的button等子控件获取不到焦点；当子控件有焦点时，item无焦点无法响应onItemClick事件ViewGroup.FOCUS_AFTER_DESCENDANTS：表示item的子控件优先于item获得焦点；ViewGroup.FOCUS_BEFORE_DESCENDANTS：表示item优先于其子控件获得焦点。

解决法：[java]viewplaincopylistView.setOnItemSelectedListener(onItemSelectedListener);privateAdapterView.OnItemSelectedListeneronItemSelectedListener=newAdapterView.OnItemSelectedListener(){@OverridepublicvoidonItemSelected(AdapterViewparent,Viewview,intposition,longid){//当此选中的item的子控件需要获得焦点时parent.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);//elseparent.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);}@OverridepublicvoidonNothingSelected(AdapterViewparent){parent.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);}}
