Question

我正在尝试使用ActionBar粗体制作标题，我想我已经拥有了所有必要的样式，但是它出现了这个错误消息：

  Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat th
eme (or descendant) with this activity.

值 - ＆GT; styles.xml：

 <resources xmlns:android="http://schemas.android.com/apk/res/android">

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="actionBarStyle">@style/MyTheme.MyActionBar</item>
</style>

  <style name="MyTheme.MyActionBar" parent="@style/Widget.AppCompat.Base.ActionBar">
    <item name="titleTextStyle">@style/MyTheme.MyActionBar.TitleTextStyle</item>
  </style>

  <style name="MyTheme.MyActionBar.TitleTextStyle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textStyle">bold</item>
  </style>

在我的清单中：

  <activity 
         android:theme="@style/AppTheme"
         android:name=".TestActivity"
         android:screenOrientation="portrait"
         android:label="Example">
     </activity>

所以它告诉我我没有使用Theme.AppCompat主题或后代，但我的AppTheme的父级是AppBaseTheme，它的父级是Theme.AppCompat.Light.DarkActionBar。那么为什么抱怨这个呢？

再次编辑： 对不起，错误消失了。但是，我的头衔仍然不大胆。这就是我的全部：

Answer 1

I'm testing in Api 17

<强>问题：

<item name="actionBarStyle">@style/MyTheme.MyActionBar</item>
<item name="titleTextStyle">@style/MyTheme.MyActionBar.TitleTextStyle</item>

actionBarStyle和titleTextStyle仅用于较低级别的API，因为您使用更高级别的API来引用名称前的android:。

<强>样品：

<item name="android:actionBarStyle">@style/MyTheme.MyActionBar</item>
<item name="android:titleTextStyle">@style/MyTheme.MyActionBar.TitleTextStyle</item>

编辑：

其中一个带有actionBarStyle值文件夹和其他主题android:actionBarStyle到v-11值文件夹

Android：操作栏中的appcompat v7粗体标题
