Question

我从http：/developer.android.com/training/search/setup.html学习如何在操作栏上添加搜索视图（我使用工具栏）。我可以添加该功能，但是当我想添加语音搜索时，麦克风图标不会显示。看起来我只需要添加android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"。

我还有另外一些问题。

我设置searchView.setIconifiedByDefault(false);，但为什么默认情况下仍然会图标化？
当我专注于另一个小部件时，如何将内容视图恢复为图标？

这是我的代码：

MainActivity.java

＆＃13;

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;
    }
}

＆＃13;

activity_main.xml中

＆＃13;

<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>

＆＃13;

searchable.xml

＆＃13;

<?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"/>

＆＃13;

试试这个..

    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()));

}

为什么语音搜索没有显示在我的工具栏搜索操作视图中？
