这个活动已经有一个由窗口装饰提供的操作栏

试图移动我的东西使用工具栏而不是操作栏，但我一直得到一个错误说

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.

然后我添加了我的样式，让我的活动没有动作栏

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

这个主题适用于我清单中的活动

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

MainActivity扩展了GooglePlayServiceActivity，所以我也设置了主题

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

但我还是得到了错误。我也不要求窗口功能的任何地方。知道为什么我还能收到这个吗?

当前回答

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

    Change this to NoActionBar 

        <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
            <!-- Customize your theme here. -->

        </style>

    This one worked for me

其他回答

在你的应用主题中添加这两行，位于style.xml:-

 <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>

    //Add this two line will fix your problem
    <item name="windowNoTitle">true</item>   <--1(this applies after 22.0.1 support library i think 
    <item name="windowActionBar">true</item> <--2

尝试更改应用程序主题的父元素

在themes.xml中更改如下

<style name="AppCompatTheme" parent="@style/Theme.AppCompat.Light">

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

或下面是在主题定义中禁用操作栏的正确方法

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

这就是我解决问题的方法。在你的AndroidMainfest.xml中添加以下代码

<activity android:name=".YourClass"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar">
 </activity>

简单地说，你可以做到以下几点:-

if (android.os.Build.VERSION.SDK_INT >= 21) {
        Window window = getWindow();
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));

    }

我也面临着同样的问题。但是我用了:

getSupportActionBar () hide ();

之前

setContentView (R.layout.activity_main);

现在它正在起作用。

我们可以在style。xml中尝试其他选项，

<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>
