Searchbar With Tablayout And Viewpager. Searchbar (edittext) Doesn't Filter Through Users, Nor Events

My SearchFragment is the host Fragment for two other Fragments: SearchUsersFragment and SearchEventsFragment. The way I have it organized is the TabLayout and Viewpager are in the

Solution 1:

I have used a searchView here for filtering 3 fragments together

searchView.setOnQueryTextListener(newSearchView.OnQueryTextListener() {
        @OverridepublicbooleanonQueryTextSubmit(String query) {
            returnfalse;
        }

        @OverridepublicbooleanonQueryTextChange(String newText) {

            mAdapter.getFilter().filter(newText);
            fAdapter.getFilter().filter(newText);
            rAdapter.getFilter().filter(newText);
            returnfalse;
        }
    });

And then in my adapters I have done implements Filterable and

@OverridepublicFiltergetFilter() {
    return myFilter;
}

privateFilter myFilter = newFilter() {
    @OverrideprotectedFilterResultsperformFiltering(CharSequence constraint) {

        ArrayList<String> filterList = newArrayList<>();

        if (constraint == null || constraint.length() == 0) {
            filterList.addAll(MainActivity.Db.getWholeData());
        } else {
            String toFilter = constraint.toString().toLowerCase().trim();

            for (String item : MainActivity.Db.getWholeData()) {
                if (item.toLowerCase().contains(toFilter)) {
                    filterList.add(item);
                }
            }
        }

        clickPurposeFav = filterList;
        FilterResults filterResults = newFilterResults();
        filterResults.values = filterList;

        return filterResults;
    }

    @OverrideprotectedvoidpublishResults(CharSequence constraint, FilterResults results) {          

        MainActivity.arrList.clear();
        MainActivity.arrList.addAll((List) results.values);

     }
};
