在我的学校应用项目中，我的ListActivity在从我的主屏幕进行搜索时未显示顶部的操作栏。我尝试使用样式Theme.Holo但是它要求我在我的主要活动上扩展ActionBarActivity，这已被弃用。现在，我正在我的主要活动上扩展AppCompatActivity，但这只会使应用程序崩溃，因为我使用Theme.Holo作为应用主题。
有没有办法让我可以使用Theme.Holo样式，而不必在主屏幕上展开ActionBarActivity？
我所要做的就是让我的ListActivity出现在最顶层的动作栏，但由于某些繁琐的原因而没有显示出来。
在我的styles.xml中：
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>

首先，您可以使用“Theme.AppCompat.Light.DarkActionBar”轻松获得带有主题ActionBar的暗材料，即Android Studio中的每个项目都附带默认的AppTheme。 其次，对于ActionBar（Material样式），您需要使用一个名为Toolbar的小部件，该小部件随API21一起提供，也可以在早期版本的Android的支持库中使用。为了将其用于API＆lt; 21，你需要在你的xml代码中添加这样的东西： -
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_activity_main_actionbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Light"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:background="?attr/colorPrimary"/>
由于它是支持库功能，您需要在根选项卡中使用以下行： -
的xmlns：应用= “http://schemas.android.com/apk/res-auto”
对于API＆gt; = 21，使用工具栏代替android.support.v7.widget.Toolbar
这将显示活动中带有黑色主题的操作栏。

您可以在getActionBar()的{{1}}中使用onCreate()。
您也可以使用ListActivity
