    DisplayMetrics dm = new DisplayMetrics();   
    dm = getApplicationContext().getResources().getDisplayMetrics();   
    int screenWidth = dm.widthPixels;   
    int screenHeight = dm.heightPixels;   
    return new Point(screenWidth ,screenHeight );  
 }

第二种：

 WindowManagerwindowManager=getWindowManager();
 Displaydisplay=windowManager.getDefaultDisplay();
