在Listfragment android中使用自定义listview刷新Listadapter

Question

我使用列表适配器将值设置为listview.values是从webservice api加载的。我需要如何使用android中的列表适配器刷新自定义列表视图。

Answer 1

There are two ways to do that:

1. Create a new adapter and set it to the ListView with setAdapter every time you reload your data.
2. Reuse the adapter (via setData or similar methods) and invoking notifyDataSetChanged after that, so the view is refreshed.

Answer 2

您需要使用适配器中的notifyDataSetChanged（），以使适配器需要扩展BaseAdapter，因此每次更改某些数据时，请调用，

instanceOfAdaper.notifyDataSetChanged()

Answer 3

I guess you must be using AsyncTask method to fetch data from WebService,Just override this method,and call notifyDataSetChanged method in onPostExecute like this.

protected void onPostExecute(String result) {
    adapter.notifyDataSetChanged();             
}
