display getSize() 过时

If you want the the display dimensions in pixels you can usegetSize: 
如果你想得到页面的像素值，使用getSize：

Display display =getWindowManager().getDefaultDisplay(); 
Point size = new Point(); 
display.getSize(size); 
int width = size.x; 
int height = size.y; 

If you're not in an Activity you can get the default Display viaWINDOW_SERVICE: 
如果代码不在Activity中，你可以通过WINDOW_SERVICE得到屏幕尺寸：

WindowManager wm = (WindowManager)ctx.getSystemService(Context.WINDOW_SERVICE); 
Display display =wm.getDefaultDisplay(); 

Before getSize was introduced (in API level 13), you coulduse the getWidth and getHeight methods that are nowdeprecated: 

在getSize没有引入前（API level 13之前），你可以使用getWidth 和getHeight 。但是已经过时：

Display display =getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  //deprecated 
int height = display.getHeight();  //deprecated
