java - 自定义主题 android 崩溃由 : java. lang.IllegalStateException : You need to use a Theme. AppCompat 主题(或后代)与此 Activity 引起

Question

我尝试以这种方式使用 AppCompat 来使用自定义主题

<resources>
    <style name="Theme.AppCompat" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
        <item name="android:windowContentOverlay">@null</item>
        <!--<item name="android:homeAsUpIndicator">@drawable/ic_drawer</item>--> 
        <item name="android:actionOverflowButtonStyle">@style/Theme.AppCompat.OverFlow</item>
  </style>

  <style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
      <item name="android:background">#00bcd4</item>
      <item name="android:windowContentOverlay">@null</item>
  </style>

    <style name="Theme.AppCompat.OverFlow">
     <item name="android:src">@drawable/menu</item>
  </style>

</resources>

当我启动应用程序时，我收到此错误:

在 list 中我写道:android:theme="@style/Theme.AppCompat"

知道为什么会崩溃吗？谢谢

Answer 1

你的 logcat 会告诉你一切

You need to use a Theme.AppCompat theme (or descendant) with this activity.

所以而不是

@android:style/Theme.Holo.Light

使用它作为您的父主题

Theme.AppCompat.Light
