Android SearchView на панели инструментов

Ответ 1

Я сделал с Фрагмент таким образом.

Я сделал с onTextChangeListener в представлении поиска, просто зарегистрируйте Logcat.

Ссылка на скриншот:

menu.xml - (res → menu)

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".HomeActivity">

    <item
        android:id="@+id/action_search"
        android:icon="@android:drawable/ic_menu_search"
        android:title="Search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always" />

</menu>

MainFragment.java

public class MainFragment extends Fragment {

    private SearchView searchView = null;
    private SearchView.OnQueryTextListener queryTextListener;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_main, container, false);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setHasOptionsMenu(true);
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.menu, menu);
        MenuItem searchItem = menu.findItem(R.id.action_search);
        SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);

        if (searchItem != null) {
            searchView = (SearchView) searchItem.getActionView();
        }
        if (searchView != null) {
            searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));

            queryTextListener = new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextChange(String newText) {
                    Log.i("onQueryTextChange", newText);

                    return true;
                }
                @Override
                public boolean onQueryTextSubmit(String query) {
                    Log.i("onQueryTextSubmit", query);

                    return true;
                }
            };
            searchView.setOnQueryTextListener(queryTextListener);
        }
        super.onCreateOptionsMenu(menu, inflater);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.action_search:
                // Not implemented here
                return false;
            default:
                break;
        }
        searchView.setOnQueryTextListener(queryTextListener);
        return super.onOptionsItemSelected(item);
    }
}

Готово
