public void onClick(View v) {
            // TODO Auto-generated method stub
            log.setText(log.getText() + "\n" +input.getText());

            if(log.getLineCount() > 5){
                scroll_amount = scroll_amount + log.getLineHeight();
                log.scrollTo(0, scroll_amount);
            }
        }

我称为变量滚动量的onCreate（）之外。再次感谢！

I called the variable scroll amount outside the onCreate(). Thanks again!
