无法在ArrayAdapter中使用style.xml attr值

当我尝试从TextView中的属性而不是styles.xml为colors.xml分配颜色时，我遇到了一个奇怪的问题。

所以我有styles.xml（摘录）定义“color_title”的颜色：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="color_title" format="reference" />

    <style name="DayTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="color_title">@color/buttonHoverBackground</item>
    </style>

    <style name="NightTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="color_title">@color/buttonBackground</item>
    </style>

</resources>

如果我在普通布局中使用它，它可以正常工作。但是当我尝试在自定义数组适配器中使用的列表项中使用它来填充ListView时，我得到一个android.view.InflateException：

  

“二进制XML文件行#XX：错误扩充类   android.widget.TextView”。

这适用于适配器：

<TextView
                    android:id="@+id/ticker_article_title"
                    android:layout_width="match_parent"
                    android:textColor="@color/black"
                    android:layout_height="wrap_content"
                    android:textSize="@dimen/news_detail_info_box_title"/>

这不起作用

<TextView
               android:id="@+id/ticker_article_title"
               android:layout_width="match_parent"
               android:textColor="?attr/color_title"
               android:layout_height="wrap_content"
               android:textSize="@dimen/news_detail_info_box_title"/>

所以我想知道这是否正常，或者为什么我不能在ArrayAdapter中使用样式属性，而它仍然适用于应用程序的其他部分。

编辑：这是完整的堆栈跟踪

stacktrace（de.mycompany.myapp.screens.adapter.NewsOverviewTickerAdapter.getView(NewsOverviewTickerAdapter.java:90)）中的第13行指向自定义ArrayAdapter中的此部分：

if (rootView == null) {
    final LayoutInflater inflater = (LayoutInflater) getContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    rootView = inflater.inflate(
            R.layout.fragment_newsoverview_ticker_listitem, null);
            ...

Edit2：这是一个示例，它显示View中的?attr/和同一布局文件和片段中的ListView的用法。该按钮使用android:textColor="?attr/color_settings_sublabels"：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <Button
            android:id="@+id/button_meine_ressorts"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:textSize="@dimen/news_detail_info_box_title"
            android:textColor="?attr/color_settings_sublabels"
            android:background="?attr/color_background"
            android:text="@string/menu_favorites_edit"
            android:textAllCaps="true"/>

        <include layout="@layout/load_data_shimmer"
                 android:id="@+id/loadingPanel_initial"/>

        <ListView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/news_ticker_list"/>

    </LinearLayout>

</RelativeLayout>
