I could resolve the problem.complete code is :

public class MultiTouchListener implements View.OnTouchListener {


    private float mPrevX;
    private float mPrevY;

    public QuranActivity mainActivity;
    public MultiTouchListener(QuranActivity mainActivity1) {
        mainActivity = mainActivity1;
    }

    @Override
    public boolean onTouch(View view, MotionEvent event) {
        float currX,currY;
        int action = event.getAction();
        switch (action ) {
            case MotionEvent.ACTION_DOWN: {

                mPrevX = event.getX();
                mPrevY = event.getY();
                break;
            }

            case MotionEvent.ACTION_MOVE:
            {

                int w = mainActivity.getWindowManager().getDefaultDisplay().getWidth() - 100;
                int h = mainActivity.getWindowManager().getDefaultDisplay().getHeight() - 100;



                currX = event.getRawX();
                currY = event.getRawY();


               ViewGroup.MarginLayoutParams marginParams = new ViewGroup.MarginLayoutParams(view.getLayoutParams());


                //marginParams.topMargin = (int)(currY - mPrevY);


            /*    if(currX>w){
                    marginParams.leftMargin = (int)(currX - mPrevX)-100;
                }
                else {
                    marginParams.leftMargin = (int)(currX - mPrevX);
                }


                if(currY>h){
                    marginParams.rightMargin = (int)(currY - mPrevY)-100;
                }
                else {
                    marginParams.rightMargin = (int)(currY - mPrevY);
                }
*/




                marginParams.setMargins(0, (int)(currY - mPrevY),0, 0);
                RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
                view.setLayoutParams(layoutParams);

                Log.e("onTouch X",currX - mPrevX+"  " + "" );
                Log.e("onTouch Y",currY - mPrevY+"  " + "" );



                break;
            }



            case MotionEvent.ACTION_CANCEL:
                break;

            case MotionEvent.ACTION_UP:

                break;
        }

        return true;
    }
}

  1. First Detect amount of area scrolled by view using Android listView find the amount of pixels scrolled
  2. Then set this scrolled height dynamically to the view Android set height and width of Custom view programmatically
