II do not understand the problem, problem: After clicking the button, you want to modify the data in the list, and if there are other operations, then be done, then call adapter.notifyDatachanged () method, the UI will be redrawn. The second chart will be displayed.

One problem: you need to spread Button Activity in adapter, with mass participation, as it can operate, and other controls are similar
Second problem: the direct use notifyDataSetChanged (); you can
For example:
Adapter refresh listview
enabled threadHandler handler = new Handler ()
{
@ Override
public void handleMessage (Message msg)
{
if (msg.what == Delete_TOPIC_SUCCESS)
{
Toast.makeText (context, "deleted successfully", Toast.LENGTH_SHORT) show ();.
myList.remove (selectIndex);
notifyDataSetChanged ();
}
else if (msg.what == Ding_TOPIC_SUCCESS)
{
Toast.makeText (context, "bumping success", Toast.LENGTH_SHORT) show ();.
. myList.get (selectIndex) setDingCount (. myList.get (selectIndex) getDingCount () +1);
notifyDataSetChanged ();
}
else if (msg.what == Ding_TOPIC_GOVER)
{
Toast.makeText (context, "the stickers that you have the top off, you can not repeat the top", Toast.LENGTH_SHORT) show ();.
notifyDataSetChanged ();
}
else
{
Toast.makeText (context, msg.getData () getString ("msg"), Toast.LENGTH_SHORT.) Show ();.
}
}
};

 case R.id.btn_house_user_cancle_id: 
Toast.makeText (mContext, "Unfollow", 0) show ();. 
viewHolder.btn_house_user_guanzhu.setVisibility (View.VISIBLE); 
break; 

For example, this will not work ah second button is not displayed. . . . . .
