更改棒棒糖工具栏文本颜色

我正在尝试在Lollipop工具栏中设置文本样式。但是，无论我尝试什么，颜色总是来自应用程序的“ text_primary”样式项，而不是我尝试覆盖它的样式。

下面是一个例子。我正在尝试使文本变白。

colors.xml：

<resources>
    <color name="primary">#8BC34A</color>
    <color name="primary_dark">#669900</color>
    <color name="accent">#64DD17</color>
    <color name="text_primary">#333</color>
    <color name="text_secondary">#424242</color>
    <color name="photo_tint">#424242</color>

    <color name="toolbarTitleText">#fff</color>
    <color name="toolbarActionMenuTextColor">#333</color>
    <color name="toolbarTextColorSecondary">#fff</color>
</resources>

styles.xml：

<resources>
    <style name="AppTheme" parent="AppTheme.Base">

        <item name="android:colorPrimary">@color/primary</item>
        <item name="android:colorPrimaryDark">@color/primary_dark</item>
        <item name="android:colorAccent">@color/accent</item>
        <item name="android:textColorPrimary">@color/text_primary</item>
        <item name="android:textColor">@color/text_secondary</item>
        <item name="android:navigationBarColor">@color/primary_dark</item>

    </style>

    <style name="ToolbarTheme" parent="Theme.AppCompat">
        <item name="android:textColorPrimary">@color/toolbarTitleText</item>
        <item name="android:textColorPrimaryInverse">@color/toolbarTitleText</item>
        <item name="actionMenuTextColor">@color/toolbarActionMenuTextColor</item>
        <item name="android:textColorSecondary">@color/toolbarTextColorSecondary</item>
    </style>

</resources>

工具栏

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"
    app:theme="@style/ToolbarTheme"
    android:theme="@style/ToolbarTheme"
    android:titleTextAppearance="@color/toolbarTitleText"
    android:subtitleTextAppearance="@color/toolbarTitleText"
    app:titleTextAppearance="@color/toolbarTitleText"
    app:subtitleTextAppearance="@color/toolbarTitleText"
    />

如您所见，我已经尝试了几种方法来在toolbar.xml中应用“ ToolbarTheme”样式。但是，没有任何效果。
