Android中带有自定义RecyclerView的InflateException

对于我的一个项目，我想构建一个自定义的recyclerview。因此，我通过以下方式扩展了RecyclerView：

class MyCustomRecyclerView : RecyclerView {
constructor(context: Context) : super(context){
initializationCode(context)
}
constructor(context: Context,attrs: AttributeSet?) : super(context,attrs){
initializationCode(context)
}
...
}


为简洁起见，我排除了自定义RecyclerView的大部分内容。如您所见，我还在Kotlin中添加了所需的构造函数作为辅助构造函数。
特别是，带有AttributeSet的构造函数对于这种自定义视图实现至关重要。现在，膨胀的XML如下所示：

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

name="postListViewModel"
type="com.celik.abdullah.myproject.viewmodels.PostFragmentViewModel" />

android:layout_
android:layout_
tools:cOntext=".ui.fragments.PostFragment">
android:id="@+id/custom_recycler_view"
android:layout_
android:layout_
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:padding="6dp"
android:clipToPadding="false"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:postListData="@{postListViewModel.postList}"
tools:listitem="@layout/post_list_item">





但是我得到以下异常：

有人可以帮忙吗？

看起来您的initializeCode在通货膨胀期间引发了异常。 InvocationTargetException包装构造函数引发的en异常。

您正在使用layoutManager属性，并且正在设置androidx的 LinearLayoutManager

app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"


尝试从XML中删除它，并从Kotlin文件中动态设置它

仔细检查是否从RecyclerView的{​​{1}}扩展MyCustomRecyclerView中的androidx。

此外，RecyclerView在RecyclerView之外也可用

请检查androidX和withoutAndroidX版本以供参考
