代码如下：

	private void init()
	{
		//九宫格适配器
		adapter = new GridViewAdapter(this, titles, imgIds);
		
		//初始化GridView
		View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.activity_morefunction, null);
		gridView = (GridView) view.findViewById(R.id.gridview);
		gridView.setAdapter(adapter);	
		//初始化PopupWindow
		popupWindow = new PopupWindow(gridView, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, true);
		popupWindow.setBackgroundDrawable(new BitmapDrawable());
	}

	private void event()
	{		
		tabWidget.getChildAt(4).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				parent = MainActivity.this.findViewById(android.R.id.tabhost);
				openPopupWindow();
			}
		});
	}

	/***
	 * 显示PopupWindow
	 */
	private void openPopupWindow()
	{
		popupWindow.showAtLocation(parent, Gravity.CENTER,0,0);
	}

求解啊！怎么样才能正常显示，急急急！

viewgroup先removeallchilds，再添加child就可以了。错误是那个child已经有一个parent了，再给他一个parent就会报错。

 popupWindow = new PopupWindow(view, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, true);
    popupWindow.setBackgroundDrawable(new BitmapDrawable());

你初始化PopupWindow干嘛用GridView

提示的很明显的你的parenta 有问题 你可以换个其他布局的地方添加以下你的PopupWindow试试看

我知道是parent有问题，我希望的效果是PopupWindow显示在TabHost上

显示popUpWindow对象之前 if(contentView != null && contentView.getParent() != null) { ((ViewGroup)contentView.getParent()).removeAllViews(); }
