android - ActionBarCompat : java. lang.IllegalStateException : You need to use a Theme. AppCompat

Question

我在 Android 2.3.5 上遇到 RuntimeException，但我是使用 Theme.AppCompat (res/values/themes.xml)。这是电话:http://www.gsmarena.com/samsung_galaxy_y_s5360-4117.php

 <!-- res/values/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>

     <style name="Theme.Styled" parent="@style/Theme.AppCompat">
         <item name="actionBarStyle">@style/QueryActionBar</item>
         <item name="android:actionBarStyle">@style/QueryActionBar</item>
     </style>

     <style name="QueryActionBar" parent="@style/Widget.AppCompat.ActionBar">
         <item name="background">@color/blueback</item>
         <item name="android:background">@color/blueback</item>
         <item name="backgroundSplit">@color/blueback</item>
         <item name="android:backgroundSplit">@color/blueback</item>
     </style>

 </resources>

这是 values-v11 的文件。

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="QueryTheme" parent="@android:style/Theme.Holo">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
 </resources>

这是错误。

抱歉，我在 AndroidManifest.xml 中也定义了 android:theme="@style/Theme.Styled"。

如果您在 MainActivity 中扩展 ActionBarActivity，您还必须更改 values-v11 中的父主题。
所以 values-v11 中的 style.xml 将是 -

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="QueryTheme" parent="@style/Theme.AppCompat">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
 </resources>

编辑:我建议您停止使用 ActionBar 并开始使用 Android Design Support Library 中包含的 AppBar 布局。
