pop Windows

在用户点击或者其他事件的时候，需要弹出一个自定义的窗口，Popup Window可以满足这种需求，效果如下：

代码如下：
view sourceprint?1.private PopupWindow Popup;
2.//how much time your popup window should appear
3.private static final int POPUP_DISMISS_DELAY = 4000
4.private DismissPopup mDismissPopup = new DismissPopup();
view sourceprint?01.Popup = new PopupWindow(this.getViewInflate()
02.                         
.inflate(R.layout.main1,null,null),0,0);   
03.Popup.setOutsideTouchable(false);
04.Popup.setTouchInterceptor(new OnTouchListener() {
05.

06. 
public boolean onTouch(View v, MotionEvent event) {
07.     
//your code when touched on the event
08. 
return false;
09. 
}
10.

11. 
});
12.

13.     
Popup.showAtLocation(this.findViewById(R.id.main2),Gravity.BOTTOM, 20, 20);
14.     
youractivity.postDelayed(mDismissPopup, POPUP_DISMISS_DELAY);
下面这个线程是为了配合设定时间关闭窗口。
view sourceprint?1.class DismissPopup implements Runnable {
2.         
public void run() {
3.             
// Protect against null-pointer exceptions
4.             
if (mPopup != null) {
5.                 
mPopup.dismiss();
6.             
}
7.         
}
8.     
}
