ExpandableListView不扩展

Question

我使用下面的代码在onGroupClickListener中设置MainActivity，我还设置了OnLongClickListener以查看名为getGroupView()的自定义适配器的MyExpandableListAdapter。< / p>

然后当我运行程序onGroupClickListener时，我从OnGroupClickListener()返回true或false。如果我从OnlongClickListener程序正常运行getGroupView()并{ {1}}会开火！这里发生了什么以及如何解决？

如果没有，则表示无法将onGroupClickListener()设置为longClickListener的组？!!!以下是MainActivity中ExpandableListView的代码

OnGroupClickListener()

以下是MyExpandableListAdapter中长按的代码：

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;               
        }

    });

试试这可能会对你有所帮助

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;               
        }

    });
