　　从日志可以看到问题的解决方法是给当前的 activity 使用 Theme.AppCompat 主题。

解决方法

　　给当前的 Activity 使用 ThemeAppCompat 主题。
　　未修改之前的主题

    <style name="AppTheme" parent="android:Theme.Holo.Light.NoActionBar.Fullscreen">
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowEnableSplitTouch">false</item>
        <item name="android:splitMotionEvents">false</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowAnimationStyle">@style/ActivityAnimStyle</item>
    </style>

　　修改之后的主题

    <style name="ServiceAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowBackground">@color/translate</item>
        <item name="android:windowAnimationStyle">@style/ActivityAnimStyle</item>
        <item name="android:windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
    </style>

　　更换主题之后，问题得到解决。
