Context中获取屏幕尺寸的2种方法

方法1：

public Point getDisplayMetrics() { 
   DisplayMetrics dm = new DisplayMetrics(); 
   dm = getApplicationContext().getResources().getDisplayMetrics(); 
   int screenWidth = dm.widthPixels; 
   int screenHeight = dm.heightPixels; 
   return new Point(screenWidth ,screenHeight );
}

 

方法2：

public Point getDisplayScreen() { 
   WindowManager windowManager = getWindowManager();
   Display display = windowManager.getDefaultDisplay();
   screenWidth  = display.getWidth();
   screenHeight = display.getHeight();
   return new Point(screenWidth ,screenHeight );
}

 

 

2种方法都可以获取当前display的screen尺寸。
