Why do Voice Search isn't shown on my toolbar search action view?

Question

I learn how to add search view on action bar (I use toolbar) from http:/developer.android.com/training/search/setup.html. I can add that feature just fine, but when I want to add voice search, mic icon isn't shown. It looks like I just need to add android:voiceSearchMode="showVoiceSearchButton|launchRecognizer" .

I also have some another questions.

1. I set searchView.setIconifiedByDefault(false); but why do it still iconified by default?
2. How do I make the content view back to icon when I focus on another widget?

Here is my code:

MainActivity.java

 public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); handleIntent(getIntent()); } private void handleIntent(Intent intent) { if (Intent.ACTION_SEARCH.equals(intent.getAction())) { String query = intent.getStringExtra(SearchManager.QUERY); TextView textView = (TextView) findViewById(R.id.query); textView.setText(query); } } @Override protected void onNewIntent(Intent intent) { setIntent(intent); handleIntent(intent); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_main, menu); SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView(); searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); searchView.setIconifiedByDefault(false); return true; } } 

activity_main.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"> <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/toolbar" android:layout_height="wrap_content" android:layout_width="match_parent" android:minHeight="?attr/actionBarSize" /> <TextView android:id="@+id/query" android:text="@string/hello_world" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/toolbar"/> </RelativeLayout> 

searchable.xml

 <?xml version="1.0" encoding="utf-8"?> <searchable xmlns:android="http://schemas.android.com/apk/res/android" android:hint="@string/search_hint" android:label="@string/app_name" android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"/>

Try this one..

    public boolean onCreateOptionsMenu(Menu menu) {
        this.menu = menu;
        MenuInflater menuInflater = getMenuInflater();
        menuInflater.inflate(R.menu.menu_main, menu);

        MenuItem searchItem = menu.findItem(R.id.action_search);
        searchView = (SearchView) searchItem.getActionView();
        searchView.setQueryHint(getResources().getString(R.string.hint));

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

}
