Didn't you get any error in GetContactAdapter ? Because you haven't overriden any methods from Filterable? — Raghavendra, Jan 02 '17 at 08:09

try this code if it might help you

public class SearchViewFilterMode extends Activity implements SearchView.OnQueryTextListener {

    private SearchView mSearchView;
    private ListView mListView;

    private final String[] mStrings = Cheeses.sCheeseStrings;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_ACTION_BAR);

        setContentView(R.layout.searchview_filter);

        mSearchView = (SearchView) findViewById(R.id.search_view);
        mListView = (ListView) findViewById(R.id.list_view);
        mListView.setAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                mStrings));
        mListView.setTextFilterEnabled(true);
        setupSearchView();
    }

    private void setupSearchView() {
        mSearchView.setIconifiedByDefault(false);
        mSearchView.setOnQueryTextListener(this);
        mSearchView.setSubmitButtonEnabled(true); 
        mSearchView.setQueryHint("Search Here");
    }

    public boolean onQueryTextChange(String newText) {
        if (TextUtils.isEmpty(newText)) {
            mListView.clearTextFilter();
        } else {
            mListView.setFilterText(newText.toString());
        }
        return true;
    }

    public boolean onQueryTextSubmit(String query) {
        return false;
    }
}

Please explain to the Author how it'll solve. Post some description along with code? — Raghavendra, Jan 02 '17 at 08:13
