试图移动我的东西Toolbar而不是动作栏,但我不断收到错误说

我得到在Android 2.3.5一个RuntimeException,但我正在用Theme.AppCompat(RES /价值/的themes.xml).这是电话:http://www.gsmarena.com/samsung_galaxy_y_s5360-4117.php

 <!-- res/values/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>

     <style name="Theme.Styled" parent="@style/Theme.AppCompat">
         <item name="actionBarStyle">@style/QueryActionBar</item>
         <item name="android:actionBarStyle">@style/QueryActionBar</item>
     </style>

     <style name="QueryActionBar" parent="@style/Widget.AppCompat.ActionBar">
         <item name="background">@color/blueback</item>
         <item name="android:background">@color/blueback</item>
         <item name="backgroundSplit">@color/blueback</item>
         <item name="android:backgroundSplit">@color/blueback</item>
     </style>

 </resources>

这是values-v11的文件.

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="QueryTheme" parent="@android:style/Theme.Holo">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
 </resources>

这是错误.

我一直在使用ToolBar它,因为它被添加到Support v7库中.我觉得我用得很好.但有一点我无法理解.为什么Google会创建这样的小部件？我的意思是我们可以ToolBar通过使用做任何事情ActionBar.我们为什么要使用ToolBar？有什么优势ToolBar了ActionBar如果有的话？是否有必要更换ActionBar的ToolBar？

任何提示都表示赞赏.并提前感谢.

PS:我发现ToolBar是一个蜕变ViewGroup.那么,我们怎么能ToolBar像Layout？有人可以发布一些代码吗？

我正在尝试构建我的应用程序,但没有成功..我尝试了几种方式,但没有任何工作.例外是:

Caused by: 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.

我的style.xml是:

<resources>

    <style name="AppTheme" parent="Theme.AppCompat.Light">

        <!-- theme customizations -->

        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowActionBar">false</item>

        <item name="android:textColorPrimary">@color/ldrawer_color</item>
        <item name="actionMenuTextColor">@color/ldrawer_color</item>
        <item name="android:textColorSecondary">@color/ldrawer_color</item>
    </style>

</resources>

正如你所看到的,我已经宣布了

<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>

这是我的manifest.xml

 <application
        android:allowBackup="true"
        tools:replace="android:icon"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" …

我试图运行我的Android应用程序时收到此错误.

奇怪的是:它只发生在Android应用程序与Jenkins一起构建(和签名)时.

当我使用eclipse的本地apk文件并将其推送到我的设备(或模拟器)时,一切正常

有任何想法吗？

编辑:AndroidManifest.xml

<application
    android:name="at.my.test.App"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"

    <activity
        android:name="SplashActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Black.NoTitleBar" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="LoginActivity"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="stateHidden" >
    </activity>
    <activity
        android:name="MyFirstActivity"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name="MySecondActivity"

    <activity

        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Black.NoTitleBar" >
    </activity>
</application>  

而themes.xml文件:

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

    <item name="android:actionBarStyle">@style/MyActionBar</item>
    <item name="android:homeAsUpIndicator">@drawable/ic_up_arrow</item>

    <item name="android:windowBackground">@android:color/white</item>
