我怎样才能获得android Honeycomb系统的屏幕宽度和高度？

Question

my code:

Display display = activity.getWindowManager().getDefaultDisplay();
DisplayMetrics displayMetrics = new DisplayMetrics();
display.getMetrics(displayMetrics);

System.out.println("screen width:"+displayMetrics.widthPixels);
System.out.println("screen heigth:"+displayMetrics.heightPixels);

when I run this program in android Honeycomb system,the output is 800 and 1232 but the device's screen is 800_1280,hao can I get it? thanks.

This piece of code works for me (if you don't mind to use undocumented methods):

Display d = getWindowManager().getDefaultDisplay();
int width, height;

Method mGetRawH;
Method mGetRawW;
try {
    mGetRawH = Display.class.getMethod("getRawWidth");
    mGetRawW = Display.class.getMethod("getRawHeight");
    width = (Integer) mGetRawW.invoke(d);
    height = (Integer) mGetRawH.invoke(d);
} catch (NoSuchMethodException e) {
    e.printStackTrace();
} catch (IllegalArgumentException e) {
    e.printStackTrace();
} catch (IllegalAccessException e) {
    e.printStackTrace();
} catch (InvocationTargetException e) {
    e.printStackTrace();
}

//You should care about orientation here
int o = getResources().getConfiguration().orientation;
if (o == Configuration.ORIENTATION_PORTRAIT) {
    if (width > height) {
        int tmp = width;
        width = height;
        height = tmp;
    }
} else if (o == Configuration.ORIENTATION_LANDSCAPE) {
    if (width < height) {
        int tmp = width;
        width = height;
        height = tmp;
    }
}

Log.d("d", "w=" + width + " h=" + height);

1280 x 752 - landscape 800 x 1232 - portrait

This 48 px are for the Andriod default notification bar...

Actually device full screen width=800 and height=1280 (including status bar, title bar) . If you run your code to get display size, the system will not include status bar height and title bar height, so you will get height as 1232 (1280-(status bar height + title bar height)) .
