溢出菜单不适用于 Appcompat

Question

我刚刚从 Eclipse 转移到 Android Studio，我正在使用 Appcompat 库，因为它默认出现在 Android Studio 中并且很难停用它。

问题是，当我创建一个 ActiveBar 时，应该显示在溢出菜单中的项目从未出现，溢出菜单图标（3 个点）也没有出现。

只创建栏中的项目，如果我触摸打开溢出菜单的硬件键，应用程序崩溃。

MainActivity.java:

public class MainActivity extends ActionBarActivity {

public final static String EXTRA_MESSAGE = "com.learning.app1.MESSAGE";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.main_activity_actions, menu);

    return super.onCreateOptionsMenu(menu);
}

main_activity_actions:

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

<item android:id="@+id/action_search"
    android:title="@string/action_search"
    android:icon="@drawable/ic_action_search"
    app:showAsAction="ifRoom" />

<item android:id="@+id/action_settings"
    android:title="@string/action_settings"
    app:showAsAction="never"/>

我用的是AndroidStudio自带的BlankActivity，只修改了main_activity_actionsXML文件。不知道是我哪里有问题还是Appcompat库有bug

如果你能帮助我，我将不胜感激。谢谢。
