在下面的代码中，分页数据存储到数据库之后，但是当我从数据库中获取新数据时，自定义列表没有显示任何数据，但是如果我转到下一个选项卡并返回它开始显示数据（注意：来自数据库的新数据成功获取仅未生成自定义列表），有什么我遗漏的吗？
下面是代码片段

mAppStatus = AppStatus.getInstance(this);
List<NameValuePair> params = new ArrayList<NameValuePair>(2);
params.add(new BasicNameValuePair(Constants.AUTH_KEY, mAppStatus
.getSharedStringValue(Constants.AUTH_KEY)));
String pageNumber = new Integer(iPageNo).toString();
params.add(new BasicNameValuePair("PAGE_NO", pageNumber));
String strJsonReponse = RestClient.getInstance(this).doApiCall(
Constants.strFeedsTab, "GET", params);
Log.i("Feeds Data Response...######",
String.valueOf(strJsonReponse));
