I am displaying a userlist and I am using serachview in my actionbar to search. When I am using the searchView in activity, it works fine but when I use it for fragment, searchview doesn't work. It does not search in the listview.
Below is my code.
UserListFragment.java

private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";

private CustomAdapter adapter;
SharedPreferences.Editor preferenceEditor;
Timer myTimer;
View view;
ActionBar actionBar;
private static final String PREFRENCES_NAME = "setPreferences";
private ProgressDialog progressBar;
String partnerKeyValue;

I have written setHasOptionsMenu(true); in onCreate of UserFragment.java The logout functionality works fine but the search isn't working.
I have tried various options given on Stackoverflow as well as from other resource, but nothing worked. :(
Any help is appreciated. Thanks in advance.
