I am working with GridView. I want to update GridView on some basis. But notifyDataSetChanged() method is not working.
I am selecting tables on basis of section name. When I select section name very first time than I got tables of that section. But when I go to sections fragment again and select diff. section than I get previously selected tables only. That means notifyDataSetChanged() is not working.
What I have tried is like below.

At last I got the solution.
I have done like below...
I was maintaining a FLAG called getTableStatus to get the tables of particular section. If the value of getTableStatus is FALSE than only TableStatusAsync is called. At first selection of section, tables are coming from web service and those tables are being inserted in DB.
On second time, selecting of SECTION, tables are coming from DB not from web service. And tables are coming from DB are of previously selected SECTION. So, there is nothing to do with notifyDataSetChanged().
I have just change the FLAG value to FALSE by calling pref.setTableStatus(false); on selection of SECTION. Now, TableStatusAsync is called every time when you change your selection of SECTION.
Modified Code...
TableScreenSectionwiseActivity.java
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
pref.setSectionId(view.getTag().toString());
pref.setTableStatus(false);
pref.setTableServiceStatus(false);
Fragment fragment = new TableScreenActivity();
ReplaceFragment.getReplaceFragment(getActivity(), fragment, "");
}
