动作栏未显示在ListActivity中

Question

I have met with a problem that i cannot see my actionbar when the MainActivity extends ListActivity. I have read some questions and answers showing it is the problem with the theme. So i changed <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> to <style name="AppTheme" parent="android:Theme.Holo"> then i got the old weird looking Actionbar.

I want the new styled Actionbar in ListActivity.

Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

You should use Toolbar, ActionBar is deprecated.
