How can I get android Honeycomb system's screen width and height?

问题

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);

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)).
