在下面的代码中，在将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，自定义列表不会显示任何数据，但是如果我转到下一个选项卡并进入回到它开始显示数据（注意：从数据库成功获取新数据只有自定义列表不会生成），有什么我缺少的东西？如何在paginition后将数据插入到自定义列表中
下面的代码片段

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));
