有时候需要动态添加数据，屏幕显示满了，数据需要滚动展示。这里主要弄懂scrollTo(0, off)方法的含义喊用法。

含义不说了，大概意思就这样。

下面来看他的用法：

 TextView textView = new TextView(AFSearchActivity.this);  
        textView.setText(\"Text View \");  
        LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(  
                LinearLayout.LayoutParams.MATCH_PARENT,  
                LinearLayout.LayoutParams.WRAP_CONTENT  
        );  
        textView.setPadding(30, 15, 0, 15);
        textView.setTextSize(30);
        textView.setTextColor(Color.WHITE);
        //增加一个TextView到线性布局中
       layout.addView(textView, p);  

        ImageView imageView = new ImageView(AFSearchActivity.this);
        imageView.setImageResource(R.drawable.im_dottend_line);

      //增加一个ImageView到线性布局中
        layout.addView(imageView, p);  
        if(sName == null || sName.equals(\"\")){
   textView.setText(\"-\");
  }else{
   textView.setText(sName);
   sName = \"\";
    mHandler.post(mScrollToBottom);  
  }
 }
 private Runnable mScrollToBottom = new Runnable()
    {  
        @Override 
        public void run()
        {  
            int off = layout.getMeasuredHeight() - nameScroll.getHeight();  
            if (off > 0)
            {  
             nameScroll.scrollTo(0, off);  
            }                         
        }  
    };
