此活動已具有窗口裝飾提供的操作欄

本文翻譯自：This Activity already has an action bar supplied by the window decor

Trying to move over my stuff to use Toolbar instead of action bar but I keep getting an error saying 嘗試移動我的東西以使用Toolbar而不是操作欄，但我不斷收到錯誤消息

so then I added in my style for my activity to have no actionbar 因此，我添加了自己的風格以使我的活動沒有操作欄

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

and the theme is applies to activties in my manifest 這個主題適用於我的清單中的活動

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

MainActivity extends GooglePlayServiceActivity so I also set the theme there too MainActivity擴展了GooglePlayServiceActivity，所以我也在那裏設置了主題

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

but I still get the error. 但是我仍然得到錯誤。 I also do not request window feature anywhere. 我也不會在任何地方請求窗口功能。 any ideas why I still get this? 任何想法爲什麼我仍然得到這個？

I think you're developing for Android Lollipop, but anyway include this line: 我認爲您正在開發Android Lollipop，但無論如何都包括以下內容：

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

to your theme declaration inside of your app/src/main/res/values/styles.xml . 到app/src/main/res/values/styles.xml內的主題聲明。

Also, if you're using AppCompatActivity support library of version 22.1 or greater, add this line: 另外，如果您使用的是22.1或更高版本的AppCompatActivity支持庫，請添加以下行：

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

Your theme declaration may look like this after all these additions: 在完成所有這些添加之後，您的主題聲明可能看起來像這樣：

<!-- 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>

Another easy way is to make your theme a child of Theme.AppCompat.Light.NoActionBar like so: 另一個簡單的方法是使您的主題成爲Theme.AppCompat.Light.NoActionBar的子級， Theme.AppCompat.Light.NoActionBar所示：

<style name="NoActionBarTheme" parent="Theme.AppCompat.Light.NoActionBar">
     ...
</style>

Go to the 'style.xml' of your project and make windowActionBar to false 轉到項目的“ style.xml”，並將windowActionBar設置爲false

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

I also faced same problem. 我也面臨同樣的問題。 But I used: 但是我用過：

getSupportActionBar().hide();

before 之前

setContentView(R.layout.activity_main);

Now it is working. 現在正在工作。

And we can try other option in Style.xml , 我們可以在Style.xml中嘗試其他選項，

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

Add this in your values/styles.xml 將此添加到您的values / styles.xml中

<style name="YourCustomTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>

<style name="AppBaseTheme" parent="YourCustomTheme">

</style>

<style name="AppTheme" parent="AppBaseTheme">

</style>

And add the following code in your values-v11/styles.xml and values-v14/styles.xml 並在values-v11 / styles.xml和values-v14 / styles.xml中添加以下代碼

<style name="AppBaseTheme" parent="YourCustomTheme">

</style>

Thats it. 而已。 It will work. 它會工作。
