Erreur de gonflage de la classe android.support.v7.widget.CardView ClassNotFoundException

J'essaye de gonfler une mise en page qui contient un CardView mais je suis confronté à quelques problèmes.

Ci-dessous est l'état d'erreur,

implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha02'
implementation 'androidx.cardview:cardview:1.0.0'

Kotlin code dans le RecyclerViewAdapter,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:card_view="http://schemas.android.com/apk/res-auto"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical">
    <android.support.v7.widget.CardView
            android:id="@+id/cardView"
            android:layout_width="match_parent"
            android:layout_height="150dp"
            card_view:cardCornerRadius="0dp"
            card_view:cardElevation="@dimen/margin10"
            card_view:cardMaxElevation="@dimen/margin10"
            card_view:contentPadding="@dimen/margin10">
        <RelativeLayout
                android:id="@+id/relativeLayout"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical"
                android:layout_gravity="center">
            <ImageView
                    android:id="@+id/iv_card_item"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerInParent="true"
                    android:tint="@android:color/white"
                    android:padding="5dp"/>
        </RelativeLayout>

    </android.support.v7.widget.CardView>

</LinearLayout>

Voici la mise en page xml.

class RecyclerViewAdapter(private val recyclerViewItems: ArrayList<HearthstoneCardItemData>, context: Context) :
    RecyclerView.Adapter<RecyclerViewHolder>() {

    private val inflater = LayoutInflater.from(context)

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerViewHolder {
        val view = inflater.inflate(R.layout.recycler_view_card_item, parent, false)
        return RecyclerViewHolder(view)
    }
}

J'ai également ajouté les bonnes dépendances dans le fichier gradle (je pense)

J'ai également nettoyé la reconstruction, toujours pas de changement Tout conseil serait apprécié!

évidemment android.support.v7.widget.CardView ne vient pas de androidx

Cela ressemble à un problème androidx . Il a été déplacé ailleurs. Essayez à nouveau d'ajouter la vue de carte au XML sans spécifier le package, puis laissez-le compléter automatiquement le package.

@EpicPandaForce Vous avez raison, androidx n'a pas migré automatiquement le package xml cardview.

Vous avez besoin de androidx.cardview.widget.CardView et non de android.support.v7.widget.CardView .

Le studio Android n'a pas complètement migré mon application vers Androidx. Mais après avoir changé le nom du package dans la mise en page xml, le problème a été résolu.

Merci à tous!

Lorsque j'ai migré vers androidx , mon Android Studio n'a pas complètement migré. Donc, le fait est que si vous migrez vers androidx , assurez-vous d'ajouter la dépendance CardView à votre build.gradle

build.gradle

<androidx.cardview.widget.CardView
    android:id="@+id/card_view"
    android:layout_gravity="center"
    android:layout_width="200dp"
    android:layout_height="200dp"
    card_view:cardCornerRadius="4dp">

    <TextView
        android:id="@+id/info_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Text"/>
</androidx.cardview.widget.CardView>

et dans votre mise en page xml

dependencies {
    // Other dependencies ...
    implementation 'androidx.cardview:cardview:1.0.0'
}
