我在Gradle文件中有以下内容:

classpath 'com.android.tools.build:gradle:1.2.3'
classpath 'com.google.gms:google-services:1.4.0-beta3'

...

compile 'com.android.support:design:23.2.0'
compile 'com.mcxiaoke.volley:library:1.0.16'
compile 'com.android.support:cardview-v7:23.2.0'
compile 'com.android.support:recyclerview-v7:23.2.0'
compile 'com.prolificinteractive:material-calendarview:0.8.0'
compile 'net.hockeyapp.android:HockeySDK:3.5.0'
compile 'com.google.code.gson:gson:1.7.2'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.google.android.gms:play-services-analytics:8.1.0'
compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:support-v4:23.2.0'

我的styles.xml:

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorControlNormal">@color/secondary_text</item>
        <item name="colorControlActivated">@color/accent_color</item>
        <item name="colorControlHighlight">@color/secondary_text</item>
        <item name="colorPrimary">@color/primary_color</item>
        <item name="colorPrimaryDark">@color/dark_primary_color</item>
        <item name="colorAccent">@color/accent_color</item>

        <item name="android:windowActionModeOverlay">true</item>
        <item name="windowActionModeOverlay">true</item>
        <item name="android:actionModeBackground">@color/dark_primary_color</item>

    </style>

我尝试更改为Base.Theme.AppCompat.Light.NoActionBar,但它不存在。我已尝试更改为compile 'com.android.support:design:23.2.0',在预览中切换API级别,重建,使缓存等无效。

有什么想法吗?

我认为这已经在支持23.3.0中修复,至少它已经为我修复了。

升级到支持库(23.3.0)后,它也发生在我身上。清理和重建解决了这个问题。
