Android 获取屏幕尺寸实例代码

实现代码：

/**

*

* android:smallScreens="true"

* android:normalScreens="true"

* android:largeScreens="true"

* android:resizeable="true"

* android:anyDensity="true" />

*

* 使Android程序支持了多种分辨率

*/

mWidthScreen = display.getWidth();

mHeightScreen = display.getHeight();

LogUtils.e("Width：" + display.getWidth());

LogUtils.e("Height：" + display.getHeight());
