Display中getHeight()和getWidth() 官方废弃

        今天使用Display获取屏幕的宽和高时出现下面的提示：

Display dp=getWindowManager().getDefaultDisplay();
        int Height=dp.getHeight();  ---->The method getHeight() from the type Display is deprecated
        int Width=dp.getWidth();    ---->The method getWidth() from the type Display is deprecated
官方解释：
int    getHeight()
This method was deprecated in API level 13. Use getSize(Point) instead. 

int     getWidth()
This method was deprecated in API level 13. Use getSize(Point) instead. 

http://developer.android.com/reference/android/view/Display.html
替代的方法：
DisplayMetrics dm = new DisplayMetrics();
                getWindowManager().getDefaultDisplay().getMetrics(dm);
SCREEN_WIDTH = dm.widthPixels;
SCREEN_HEIGHT = dm.heightPixels;

解析heightPixels和widthPixels：
public int     heightPixels     The absolute height of the display in pixels.
public int     widthPixels     The absolute width of the display in pixels.
