Android:错误膨胀类<unknown>,原因:缺少主题.AppCompat主题[复制]

我正在尝试在一个回收查看项目中使用自定义表布局。请注意,相同的组件已经在应用程序的其他部分中使用过,没有问题(从未在recycleriew tho中出现过)。

我要充气的项目只包含TabLayout:

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <my.package.CustomTabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_constraintTop_toTopOf="parent">

            <android.support.design.widget.TabItem
                android:id="@+id/tab1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/text1" />

            <android.support.design.widget.TabItem
                android:id="@+id/tab2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/text2" />

        </my.package.CustomTabLayout>

    </android.support.constraint.ConstraintLayout>

</layout>

例外情况:

DataBindingUtil.inflate(LayoutInflater.from(MyApplication.getContext()), R.layout.tabs_item, parent, false)

适配器中有其他膨胀,工作正常。

有什么想法吗?
