yes take a bitmap in the canvas and draw it by specifying the coordinates

eg.

          int Down_yvalue=0;
          int Current_yvalue=0;
          Bitmap bmp1 = BitmapFactory.decodeResource(getResources(), R.drawable.face);
      canvas.drawBitmap(bmp1, Down_yvalue, Current_yvalue, new Paint());

and ontouch event get the coordinates and redraw it by calling this method invalidate eg .

               public boolean onTouchEvent(MotionEvent event) {
               Down_yvalue=(int)event.getX();
               Current_yvalue=(int) event.getY();
               invalidate() ;
            }
