    final PopupWindow popupWindow = new PopupWindow(mView, 
 LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);

 .findViewById(R.id.radio0); 
    final RadioButton radio2 = (RadioButton) mView 
 .findViewById(R.id.radio1); 
    final RadioButton radio3 = (RadioButton) mView 
 .findViewById(R.id.radio2); 
 
    Button btn1 = (Button) mView.findViewById(R.id.button1); 
    btn1.setonClickListener(new onClickListener() { 
 
      @Override 
      public void onClick(View v) { 
 //确定按钮实现的操作  
 popupWindow.dismiss(); 
      } 
    }); 
    Button btn2 = (Button) mView.findViewById(R.id.button2); 
    btn2.setonClickListener(new onClickListener() { 
 
      @Override 
      public void onClick(View v) { 
 // 取消按钮实现的操作 
 popupWindow.dismiss(); 
      } 
    }); 
 
    popupWindow.setBackgroundDrawable(new BitmapDrawable()); 
    popupWindow.showAtLocation(findViewById(R.id.RelativeLayout1), 
 Gravity.CENTER | Gravity.CENTER, 0, 0);//在屏幕的中间位置显示
