操作欄背景不變

我已經在android上，並按照他們的指示風格的行動欄，它不工作。該應用程序不斷停止。顯示消息時，我可以看到變化的顏色。我有一個注2：4.4.2。這裏是我的操作欄背景不變

styles.`

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
<!-- the theme applied to the application or activity --> 
<style name="CustomActionBarTheme" 
    parent="@android:style/Theme.Holo.Light.DarkActionBar"> 
    <item name="android:actionBarStyle">@style/MyActionBar</item> 
</style> 

<!-- ActionBar styles --> 
<style name="MyActionBar" 
    parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse"> 
    <item name="android:background">#F00</item> 
</style> 
</resources>`

清單

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="funnestgames.actionbar" > 

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

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

</manifest>

和我的logcat。

您可以從您的MainActivity類別下改變背景顏色

ActionBar actionBar = getSupportActionBar(); 
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#C71585")));

，或者如果您使用以下的風格爲您的ActionBar它不會給你錯誤

<style name="MyActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
