Android SearchView in der Toolbar

Question

Ich habe versucht, in meiner Aktivität die Suchansicht aus dem Menü hinzuzufügen, kann aber keine Suchansicht in der Symbolleiste hinzufügen, wie ich die Suchansicht in meiner Aktivitätsleiste hinzufüge.

Answer 1

Ich habe mit Fragment auf diese Weise getan.

Ich habe mit onTextChangeListener von Suchansicht, überprüfen Sie einfach Ihre Logcat.

     if (searchView != null) { 
      searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName())); 

      queryTextListener = new SearchView.OnQueryTextListener() {

    @Override

     switch (item.getItemId()) { 
      case R.id.action_search: 
       // Not implemented here 
       return false; 
      default: 
       break;
