Re-initialise position of ImageButton in Android

Question

In this problem i wanted to change the position of the ImageButton frequently. After the first initialization the ImageButton is not changing its position. Here is the code...

runOnUiThread(new Runnable() {
        public void run()
        {
            for(int i=0;i<60;i++)
            {
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                }
                img.refreshDrawableState();

                Random r=new Random();
                int a=r.nextInt();
                int b=r.nextInt();

                if(a<0)
                    a=a*(-1);
                if(b<0)
                    b=b*(-1);

                w=(a%(width-50))-72;
                h=(b%(height-50))-30;



                img.refreshDrawableState();
                img.setLeft(w);
                img.setTop(h);

                Toast.makeText(getApplicationContext(), "width : "+w+"\theight : "+h, Toast.LENGTH_SHORT).show();
            }
        }
    });

The variables height & width are height & width of the screen

Then it's logical that you button doens't move.. the relativelayout works as designed — Tobrun, Aug 22 '13 at 14:29
Learn about the different types of viewgroups here: http://developer.android.com/reference/android/view/ViewGroup.html (different types of viewgroups can be selected in the known subclasses item). If you want to use x,y coordinates then absoluteLayout will the way to go, but this is not the android way (not anymore atleast hence it deprecated) — Tobrun, Aug 22 '13 at 14:39

You should use an Absolute Layout and set the layout parameters. I found this question/answer useful when I needed to do something similar.
