Getting the size of the window WITHOUT title/notification bars

Question

I\'ve been playing around with Android development and one of the things I\'d like to be able to do is dynamically create a background image for my windows, similar to the one b

Answer 1

Use View.MeasureSpec.getSize method in onMeasure override.

    @Override
protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)
{
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);
    ...
}

Answer 2

To accomplish this in my app, I had to find a View's dimensions within the main Activity. It looked something like this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    gestureScanner = new GestureDetector(this);   //Object for handling gestures.

    mvView = new MyView(this);  //MyView is class that extends View.
    setContentView(myView);
}

@Override
public void onShowPress(MotionEvent e) {

    //Returns the size of the entire window, including status bar and title.
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics(dm);

    //Try to find the dimension of the view without the status/title bars.
    int iViewHeight = mvMountain.getHeight();
    int iViewWidth = mvMountain.getWidth();


    Toast toast = Toast.makeText(this," View:" + iViewWidth + ","+iViewHeight + " Window: " + dm.widthPixels + " by " + dm.heightPixels, 2);
    toast.show();
}

I have a tutorial on my blog that give you the ability to save your screen size on launch, You can read it here: http://evgeni-shafran.blogspot.com/2011/01/android-screen-size-problem.html

Basicly you need to overide an onMeasure method of the first layout that hold you full screen, and get the width and height from there

Answer 4

in the first onDraw, call getWidth, getHeight. these will not be valid before then.

if you are not using a custom view/layout then you can instead call getWidth/getHeight during the first onWindowFocusChanged

Answer 5

have a look at getwidth() and getheight() maybe? that should give you the size of the screen. though, I don't know If it takes the bars or not. But I don't think so...
