Add this to your onCreate:

 yourView.setOnTouchListener(new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            drag(event, v);
            return false;
        }
    });

And this to your Activity Class outside any methods.

       public void drag(MotionEvent event, View v)
        {

            RelativeLayout.LayoutParams params = (android.widget.RelativeLayout.LayoutParams) v.getLayoutParams();

            switch(event.getAction())
            {
               case MotionEvent.ACTION_MOVE:
               {
                 params.topMargin = (int)event.getRawY() - (v.getHeight());
                 params.leftMargin = (int)event.getRawX() - (v.getWidth()/2);
                 v.setLayoutParams(params);
                 break;
               }
               case MotionEvent.ACTION_UP:
               {
                 params.topMargin = (int)event.getRawY() - (v.getHeight());
                 params.leftMargin = (int)event.getRawX() - (v.getWidth()/2);
                 v.setLayoutParams(params);
                 break;
               }
               case MotionEvent.ACTION_DOWN:
               {
                v.setLayoutParams(params);
                break;
               }
            }
