android获得屏幕高度和宽度

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();
