Answer 1

从Android操作栏样式生成器生成主题时，选择样式兼容性为AppCompat，然后重新生成。我猜你必须把它留给默认的Holo，这是创造这个错误

使用AppCOmpat主题重新生成可以解决您的问题

我的清单代码：

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/Theme.Tellfaactionbarstyle2">
    <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>
    <activity
        android:name=".MainActivity2"
        android:label="@string/title_activity_main_activity2">
    </activity>
    <activity
        android:name=".cal_activity"
        android:label="@string/title_activity_cal_activity">
    </activity>
</application>

和我的样式代码：

    <item name="android:background">@drawable/btn_cab_done_tellfaactionbarstyle2</item>
</style>

<!-- this style is only referenced in a Light.DarkActionBar based theme -->
<style name="Theme.Tellfaactionbarstyle2.Widget" parent="@style/Theme.AppCompat">
    <item name="popupMenuStyle">@style/PopupMenu.Tellfaactionbarstyle2</item>
    <item name="dropDownListViewStyle">@style/DropDownListView.Tellfaactionbarstyle2</item>
</style>
