android獲得屏幕高度和寬度

android獲取屏幕的高度和寬度用到WindowManager這個類，兩種方法：

 

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();
