ListView的刷新取到列表顶部 [英] ListView refresh taking it to the top of the list

问题描述

场景：我使用的自定义适配器列表视图。我取每5秒内的数据，然后在列表视图中显示它。

问题：每一个后刷新顶部的列表滚动。我希望该列表保持原样从滚动的立场和公正的基础数据被刷新。

当前code：这就是所谓的我每次获取新的数据时

  mListAdapter =新CustomListAdapter（这一点，mListData）;
mList.setAdapter（mListAdapter）;
 

解决方案

而不是你的code的

请尽量把每次获取数据时这一个：

  adapter.notifyDataSetChanged（）;
 

Scenario: I am using a listview with custom Adapter. I am fetching data every 5 seconds and then displaying it in the listview.

Problem: After every refresh the list scrolls at the top. I would want the list to stay as is from the scroll standpoint and just the underlying data to be refreshed.

Current code: This is called every time I fetch a new data.

mListAdapter = new CustomListAdapter(this, mListData);
mList.setAdapter(mListAdapter);

解决方案

Instead of your code please try to put every time you fetch data this one:

adapter.notifyDataSetChanged();
