这个 Activity 已经有一个由窗口装饰提供的操作栏 [英] This Activity already has an action bar supplied by the window decor

问题描述

试图移动我的东西以使用 Toolbar 而不是操作栏，但我一直收到错误提示

Trying to move over my stuff to use Toolbar instead of action bar but I keep getting an error saying

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.tyczj.weddingalbum/com.xxx.xxx.MainActivity}: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

然后我在我的样式中添加了我的活动没有操作栏

so then I added in my style for my activity to have no actionbar

<style name="AppCompatTheme" parent="@style/Theme.AppCompat.Light">
        <item name="android:windowActionBar">false</item>
</style>

主题适用于我的清单中的活动

and the theme is applies to activties in my manifest

<activity
        android:name=".MainActivity"
        android:windowSoftInputMode="adjustResize|stateHidden"
        android:theme="@style/AppCompatTheme" android:screenOrientation="portrait"/>

MainActivity 扩展了 GooglePlayServiceActivity 所以我也在那里设置了主题

MainActivity extends GooglePlayServiceActivity so I also set the theme there too

<activity
       android:name=".GooglePlayServicesActivity"
       android:label="@string/title_activity_google_play_services"
       android:theme="@style/AppCompatTheme">

但我仍然收到错误消息.我也不在任何地方请求窗口功能.任何想法为什么我仍然得到这个?

but I still get the error. I also do not request window feature anywhere. any ideas why I still get this?

推荐答案

我认为你是在为 Android Lollipop 开发，但无论如何包括这一行:

I think you're developing for Android Lollipop, but anyway include this line:

<item name="windowActionBar">false</item> 

到 app/src/main/res/values/styles.xml 中的主题声明.

此外，如果您使用的是 22.1 或更高版本的 AppCompatActivity 支持库，请添加以下行:

Also, if you're using AppCompatActivity support library of version 22.1 or greater, add this line:

<item name="windowNoTitle">true</item>

添加所有这些内容后，您的主题声明可能如下所示:

Your theme declaration may look like this after all these additions:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>
