maxScrollX = horizontalScrollView.getChildAt(0) .getMeasuredWidth()-horizontalScrollView.getMeasuredWidth(); if (horizontalScrollView.getScrollX()==0) { lImageView.setImageResource(R.drawable.left_green); }else { lImageView.setImageResource(R.drawable.left); } if (horizontalScrollView.getScrollX()==maxScrollX) { rImageView.setImageResource(R.drawable.right_green); }else { rImageView.setImageResource(R.drawable.right); } — jack, Mar 08 '12 at 03:36

    maxScrollX = horizontalScrollView.getChildAt(0).getMeasuredWidth()-horizontalScrollView.getMeasuredWidth(); 
    if (horizontalScrollView.getScrollX() == 0) { 
        lImageView.setImageResource(R.drawable.left_green); 
    } else { 
        lImageView.setImageResource(R.drawable.left); 
    }

    if (horizontalScrollView.getScrollX() == maxScrollX) { 
        rImageView.setImageResource(R.drawable.right_green); 
    } else { 
        rImageView.setImageResource(R.drawable.right); 
    }
