android获取屏幕的高度和宽度用到WindowManager这个类，两种方法： 

 
1、WindowManager wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE);
 
     int width = wm.getDefaultDisplay().getWidth();
     int height = wm.getDefaultDisplay().getHeight();
 
2、WindowManager wm = this.getWindowManager();
 
     int width = wm.getDefaultDisplay().getWidth();
     int height = wm.getDefaultDisplay().getHeight();
