android获取屏幕的高度和宽度

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();




WindowManager wm = (WindowManager)this.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();
