如何在 longItemClick [重复] 后实现 ExpandableListView 发布的侦听器

Question

在我的项目中，在OnLongClick 事件之后发布ExpandableListView 项目时，我需要执行一些操作。这个怎么做？谁能举个简单的例子？

Answer 1

expandableListview.setOnItemLongClickListener(new OnItemLongClickListener() {
      @Override
      public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
          int itemType = ExpandableListView.getPackedPositionType(id);

          if ( itemType == ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
              childPosition = ExpandableListView.getPackedPositionChild(id);
              groupPosition = ExpandableListView.getPackedPositionGroup(id);

              //do your per-item callback here
              return true; //true if we consumed the click, false if not

          } else if(itemType == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
              groupPosition = ExpandableListView.getPackedPositionGroup(id);
              //do your per-group callback here
              return true; //true if we consumed the click, false if not

          } else {
              // null item; we don't consume the click
              return false;
          }
  });
