解决方案
创建一个的ArrayList＆LT;整数GT;状态与同尺寸为的ArrayList＆LT;＆HashMap的LT;字符串，字符串＆GT;＆GT;数据; 现在，只要你发出请求并获得成功，该位置添加到状态。然后里面getView（）方法：
如果（status.contains（新的整数（位置）））{
button.setText（应用）;
}
其他{
button.setText（应用）;
}
此外，做出 adapter.notifyDataSetChanged（）的调用您已经添加了位置，状态数组列表后。这将确保该列表将被刷新。
I have a list with button Apply.When the user clicks on the apply button an popup is called from which user enters some values and sends the values to the web service.When i get success response the webservice i want to refresh my list so that the text on button that is Apply should be changed to Applied

解决方案
Create an ArrayList<Integer> status with the same size as ArrayList<HashMap<String, String>> data; Now, whenever you make the request and get success, add the position to status. Then inside getView() method :
if(status.contains(new Integer(position))) {
button.setText("Applied");
}
else {
button.setText("Apply");
}
Also, make a call to adapter.notifyDataSetChanged() after you've added the position to status arraylist. This'll ensure that the list is refreshed.
