RecyclerView onCreateViewHolder Return Type Incompatibility With Multiple Custom ViewHolders

The RecyclerView.Adapter is a parameterized class that takes in a single ViewHolder type. Your definition probably looks like:

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MenuItemViewHolder>

It should be:

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>

Don't forget to have the right definition for onBindViewHolder as well. You need to override getItemViewType as well.

Full working code

For those who want a full working code. There you go.

 public class YourListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {      private static final int LAYOUT_ONE= 0;      private static final int LAYOUT_TWO= 1;      @Override      public int getItemViewType(int position)      {          if(position==0)             return LAYOUT_ONE;          else             return LAYOUT_TWO;      }      @Override      public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {         View view =null;         RecyclerView.ViewHolder viewHolder = null;         if(viewType==LAYOUT_ONE)         {             view = LayoutInflater.from(parent.getContext()).inflate(R.layout.one,parent,false);            viewHolder = new ViewHolderOne(view);         }         else         {            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.two,parent,false);            viewHolder= new ViewHolderTwo(view);         }        return viewHolder;      }      @Override      public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {          if(holder.getItemViewType()== LAYOUT_ONE)          {              // Typecast Viewholder               // Set Viewholder properties               // Add any click listener if any           }          else {              ViewHolderOne vaultItemHolder = (ViewHolderOne) holder;              vaultItemHolder.name.setText(displayText);              vaultItemHolder.name.setOnClickListener(new View.OnClickListener() {                     @Override                     public void onClick(View v) {                      .......                     }                });            }        }     //****************  VIEW HOLDER 1 ******************//      public class ViewHolderOne extends RecyclerView.ViewHolder {          public TextView name;          public ViewHolderOne(View itemView) {               super(itemView);               name = (TextView)itemView.findViewById(R.id.displayName);          }      }   //****************  VIEW HOLDER 2 ******************//      public class ViewHolderTwo extends RecyclerView.ViewHolder{          public ViewHolderTwo(View itemView) {          super(itemView);           .....
