RecyclerExampleAdapter gives errors

[sschueller]

I am trying to implement the second example (Recipe 2 RecyclerView with Advanced ads) but I run into the following Issues:

RecyclerExampleAdapter.java

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.ViewGroup;
import android.widget.ListView;
import com.clockbyte.admobadapter.ViewWrapper;
import java.util.ArrayList;
import java.util.List;

public class RecyclerExampleAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private List<String> items = new ArrayList<String>();
    private Context mContext;

    public RecyclerExampleAdapter(Context context){
        mContext = context;
    }

    @Override
    public viewGroup onBindViewHolder(ViewWrapper<RecyclerViewExampleItem> viewHolder, int position) {
        RecyclerViewExampleItem rvei = viewHolder.getView();
        String str = getItem(position);
        rvei.bind(str);
    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    @Override
    protected RecyclerViewExampleItem onCreateItemView(ViewGroup parent, int viewType) {
        RecyclerViewExampleItem rvei = new RecyclerViewExampleItem(mContext);
        return rvei;
    }

    @Override
    public String getItem(int position) {
        return items.get(position);
    }

    public void addAll(List<String> lst){
        items.addAll(lst);
    }
}

RecyclerViewExampleItem.java

import android.content.Context;
import android.widget.FrameLayout;
import android.widget.TextView;

public class RecyclerViewExampleItem extends FrameLayout {

    TextView tvText;

    public RecyclerViewExampleItem(Context context) {
        super(context);
        //inflate(context, R.layout.recyclerview_item, this);
        //tvText = ((TextView) findViewById(R.id.tvText));
    }

    public void bind(String str){
        tvText.setText(str); //publishing the text from you data collection to each item in the RecyclerView
    }
}

Gives:

• Class 'RecyclerExampleAdapter' must either be declared abstract or implement abstract method 'onBindViewHolder(VH, int)' in 'Adapter
• Method does not override method from its superclass for public viewGroup onBindViewHolder
• Method does not override method from its superclass for protected RecyclerViewExampleItem onCreateItemView
• Method does not override method from its superclass for public String getItem

If I let Android Studio generate the methods I get:

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return null;
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

    }

What am I missing?

Figured it out. Wiki is out of date, sample app works.

@sschueller Sorry for late answer. Yeah seems like that. I've updated Wiki.
