ExpandableListView不展開

Question

我使用下面的代碼在MainActivity設置onGroupClickListener ，並且還將OnLongClickListener設置為在名為MyExpandableListAdapter自定義適配器的getGroupView()中進行查看。

然后，當我運行程序onGroupClickListener永遠不會觸發，我會從OnGroupClickListener()返回true或false。如果我從getGroupView()程序中刪除OnlongClickListener ， onGroupClickListener()正常運行，並且onGroupClickListener()將觸發！ 這里發生了什么以及如何解決？

如果不是那樣，則無法將longClickListener設置為ExpandableListView組？!!!這是MainActivity中OnGroupClickListener()的代碼

exListView.setOnGroupClickListener(new OnGroupClickListener(){

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v,
                int groupPosition, long id) {                               
            gallery.setAdapter(new ImageAdapter(getBaseContext(),(Bitmap[]) exListAdapter.getChild(groupPosition, 7)));             
            lastClickedGroup=groupPosition;                 
            return false;               
        }

    }); 

這是在MyExpandableListAdapter中長按的代碼：

arg2.setOnLongClickListener(new OnLongClickListener(){

        @Override
        public boolean onLongClick(View view) {
            DetailDialog.getDialog(screen.getContext(),(String)getChild(arg0,5));
            return true;
        }

    });

試試這個可能對你有幫助

exListView.setOnGroupClickListener(new OnGroupClickListener(){

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v,
                int groupPosition, long id) {                               
            gallery.setAdapter(new ImageAdapter(getBaseContext(),(Bitmap[]) exListAdapter.getChild(groupPosition, 7)));             
            lastClickedGroup=groupPosition;                 
            exListView.expandGroup(groupPosition);//UPDATE HERE
            return false;               
        }

    });
