[2] popupWindow的应用

来源: 互联网发布时间: 2014-02-18

popupWindow的使用

1.定义一个Popupwindow:

private PopupWindow popWinOfKeyboard;
private LayoutInflater inflater ;

2.onCreate()

  inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.keyboard, null);
        
        popWinOfKeyboard = new PopupWindow(layout, 480, 350);//设置popupwindow的宽高
        popWinOfKeyboard.setAnimationStyle(R.style.PopupAnimation);
        popWinOfKeyboard.setOutsideTouchable(true);//设置点击PopopWindow的其他位置的时候关闭,无效！！
        
        View myPopView = popWinOfKeyboard.getContentView();//这个很重要！没有这个就找不到，就会nullpoint

                dialNum0 = (ImageButton)myPopView.findViewById(R.id.dial_num_0);
		dialNum1 = (ImageButton)myPopView.findViewById(R.id.dial_num_1);
		dialNum2 = (ImageButton)myPopView.findViewById(R.id.dial_num_2);
               //................
               dialNum0.setOnClickListener(this);
		dialNum1.setOnClickListener(this);
		dialNum2.setOnClickListener(this);
               //..............

3.显示

@Override
	public void onAttachedToWindow()
	{
		//放在这里面比较给力啊
		super.onAttachedToWindow();
		popWinOfKeyboard.showAtLocation(tvTitleText, Gravity.CENTER, 0, 145);//这里的布局可能有问题！！！
	}

4.关闭

popWinOfKeyboard.dismiss();
