Display中getHeight()和getWidth() 官方廢棄

        今天使用Display獲取屏幕的寬和高時出現下面的提示：

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

官方解釋：
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.

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.
