Using java Syntax Highlighting
  1.  private float mx,my;

  3.     @Override
  4.  
  5.     public boolean onTouchEvent(MotionEvent event)
  6.  
  7.     {
  8.  
  9.         ImageView switcherView = (ImageView)mSwitcher.getCurrentView();
  10.  
  11.         float curX,curY;
  12.  
  13.         switch(event.getAction())
  14.  
  15.         {
  16.  
  17.            case MotionEvent.ACTION_DOWN :
  18.  
  19.                    mx = event.getX();
  20.  
  21.                    my = event.getY();
  22.  
  23.                    break;
  24.  
  25.           case MotionEvent.ACTION_MOVE :
  26.  
  27.                    curX = event.getX();
  28.  
  29.                    curY = event.getY();
  30.  
  31.                    switcherView.scrollBy((int)(mx - curX),(int)(my - curY));
  32.  
  33.                    mx = curX;
  34.  
  35.                    my = curY;
  36.  
  37.                    break;
  38.  
  39.            case MotionEvent.ACTION_UP :
  40.  
  41.                    curX = event.getX();
  42.  
  43.                    curY = event.getY();
  44.  
  45.                    switcherView.scrollBy((int)(mx - curX),(int)(my - curY));
