您需要为子项和组项设置单独的单击侦听器,如下所示
expandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView expandableListView, View view,
int groupPosition, int childPosition, long l) {
Item item = (Item) topicListAdapter.getChild(groupPosition,childPosition);
handleClick(item);
return false;
}
});
expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView expandableListView, View view, int groupPosition, long l) {
Item item = (item) topicListAdapter.getGroup(groupPosition);
handleClick(item);
return false;
}
});
