怎么获取屏的分辨率信息？

如何获取屏的分辨率信息？？
通过什么api，谢谢

[解决办法]

 First you need to get the WindowManager by :

 WindowManager wm = getSystemService(Context.WINDOW_SERVICE);

 Next use the method to retrieve a Display object:

 Display d = wm.getDefaultDisplay();

 and finally the resolution:

 int height = d.getHeight();
 int width = d.getWidth();
