code is as follows :

  
  	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);
  	}
