RecyclerView OnClicklistener ne répond pas

Question

Tout d'abord je sais qu'il y a des centaines de ces questions mais les réponses n'ont pas résolu mon problème. Je pense que c'est quelque chose de petit qui me manque, fondamentalement j'ai ajouté un RecyclerView et ai besoin de commencer une nouvelle activité quand une carte est cliquée.

J'ai suivi ce tutoriel et ça a été fluide jusqu'à ce point. https://guides.codepath.com/android/using-the-recyclerview

C'est le recycleur

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".MainActivity"> 

    <ImageView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/bgImg" 
     android:scaleType="centerCrop"/> 

    <android.support.v7.widget.RecyclerView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/RV" 
     /> 

</FrameLayout> 

Ceci est la carte

<android.support.v7.widget.CardView 
    xmlns:card_view="http://schemas.android.com/apk/res-auto" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/card_view" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    card_view:cardCornerRadius="4dp" 
    android:layout_margin="5dp" 
    android:clickable="true" 
    android:background="?android:attr/selectableItemBackground"> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 

    <ImageView 
     android:id="@+id/vendor_image2" 
     android:layout_width="fill_parent" 
     android:layout_height="240dp" 
     android:padding="5dp" /> 

    <RelativeLayout android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@+id/vendor_image2" 
     > 

     <TextView 
      android:id="@+id/vendor_name2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textAppearance="?android:attr/textAppearanceMedium" 
      android:textStyle="bold" 
      android:layout_marginLeft="10dp" 
      android:layout_marginTop="5dp" 
      android:paddingBottom="5dp"/> 

     <TextView 
      android:id="@+id/vendor_content2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginLeft="15dp" 
      android:layout_marginTop="7dp" 
      android:layout_toEndOf="@+id/vendor_name2" 
      android:textColor="@color/text_col" 
      android:paddingBottom="5dp" /> 

     <TextView 
      android:id="@+id/vendor_suburb2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textStyle="italic" 
      android:textColor="@color/text_col" 
      android:layout_below="@+id/vendor_name2" 
      android:layout_marginLeft="10dp" /> 
     <RatingBar 
      android:id="@+id/MyRating2" 
      style="?android:attr/ratingBarStyleSmall" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_below="@id/vendor_suburb2" 
      android:layout_marginLeft="10dp" 
      android:isIndicator="true" 
      android:layout_marginTop="5dp" 
      android:layout_marginBottom="5dp" 
      android:numStars="5" 
      android:textColor="@android:color/black" 
      android:rating="3.5" 
      android:stepSize="0.1" /> 

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

Et enfin l'adaptateur et gestionnaire

Je pense que vous avez juste oublié de régler la onClickListener dans votre constructeur ViewHolder:

public VendorHolder(View itemView) 
    { 
     //These pull as null 
     super(itemView); 
     Vvendor_image = (ImageView)itemView.findViewById(R.id.vendor_image2); 
     Vvendor_name = (TextView)itemView.findViewById(R.id.vendor_name2); 
     Vvendor_content =(TextView)itemView.findViewById(R.id.vendor_content2); 
     Vvendor_suburb = (TextView)itemView.findViewById(R.id.vendor_suburb2); 
     Vrating = (RatingBar) itemView.findViewById(R.id.MyRating2); 

     // If it should be triggered only when clicking on a specific view, replace itemView with the view you want. 
     itemView.setOnClickListener(this); 
    }
