在ActionBar Android中显示SearchView

我试图在活动的

操作栏中显示
搜索视图
。我在这里遵循了android开发者指南
但是没有显示
SearchView
，我不知道为什么。
这是我的活动代码

    public class SearchActivity extends ActionBarActivity {


    private String query;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        FacebookSdk.sdkInitialize(getApplicationContext());
        super.onCreate(savedInstanceState);
        setContentView(R.layout.search_activity_layout);


        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            this.query = intent.getStringExtra(SearchManager.QUERY);
            Toast.makeText(this,query, Toast.LENGTH_LONG);
        }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.options_menu, menu);

        return true;
    }

}

下面是
serachable.xml
文件

    <?xml version="1.0" encoding="utf-8"?>

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search_hint" />

这是舱单

<activity android:name=".SearchActivity"
              android:label="SearchActivity">

        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <meta-data android:name="android.app.searchable"
            android:resource="@xml/searchable"/>


    </activity>



唯一奇怪的是，
options\u menu.xml
文件中的这一行（
android:showAsAction=“collapseActionView | ifRoom”
）以红色突出显示
 试着把它放在您的选项菜单.xml中：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/search"
        android:title="@string/search_title"
        android:icon="@drawable/ic_action_search"
        app:actionViewClass="android.widget.SearchView"
        app:showAsAction="collapseActionView|ifRoom" />
</menu>

请尝试将此项放入您的选项_menu.xml中：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
