Unable to get the correct screen size using Services for Android

So i am trying to get the screen size of the Moto Droid on my application. on my Create, i am using the Service windowManager to get the default display.

Display display = getWindowManager().getDefaultDisplay();
    int width = display.getWidth(); 
    int height = display.getHeight();

When i set it i get width of 320 and height 570. that looks wrong, it should be 320x480. i want to place a 300x50 image on the bottom of the screen on any device (actually) so normally i would get the height of the screen and minus the image height so it places it on a view. but since i am getting 570 for some reason, i have to scroll down to see the image. why is it getting the wrong screen size and is there another more accurate 开发者_JAVA技巧way of getting the size. Thank you

Layout code goes as follows

   linearOut = new LinearLayout(this);
    linear = new LinearLayout(this);
    linear.setOrientation(LinearLayout.VERTICAL);


    scroll = new ScrollView(this);
    linearOut.addView(scroll);
    scroll.addView(linear);

            linear.addView(text);
    linear.addView(bbottom.getViewGroup());

    setContentView(linearOut);

try this::

Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
    int width = display.getWidth(); 
    int height = display.getHeight();

I think i got it. so the info above shows full screen viewable. so that does include the status bar. Is there a way to see the height of the status bar? i am not sure if all android devices have the same pixel height for the status bar.
