EDIT:

public class RecyclerAdapterChooseCountry extends RecyclerView.Adapter<RecyclerAdapterChooseCountry.MyViewHolder> {

private LayoutInflater inflater;

List<CountryInformation> data = Collections.emptyList();

public RecyclerAdapterChooseCountry(Context context, List<CountryInformation> data) {
    inflater = LayoutInflater.from(context);
    this.data = data;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = inflater.inflate(R.layout.country_list, parent, false);
    MyViewHolder holder = new MyViewHolder(view, mActivity /*<- cant add this*/ );
    return holder;
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {

    CountryInformation information = data.get(position);

    holder.title.setText(information.title);
    holder.icon.setImageResource(information.iconId);

}

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


public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    TextView title;
    ImageView icon;

    private Activity mActivity;

    public MyViewHolder(View itemView, Activity mActivity  ) {
        super(itemView);

        title = (TextView) itemView.findViewById(R.id.list_title);
        icon = (ImageView) itemView.findViewById(R.id.list_item);
        icon.setOnClickListener(this);
        this.mActivity = mActivity;
    }

    @Override
    public void onClick(View v) {

        String selectedCountry;

        int country = getPosition();

        String ololo = Integer.toString(country);

        Log.i("WORKS", "Выюрана страна под номером" + ololo);
        switch (getPosition()) {

                mActivity.setResult(mActivity.RESULT_OK, intent);
                mActivity.finish();

                break;
            case 1:

Answer 1

Can't set method setResult in RecyclerAdapter

setResult is not accessible inside MyViewHolder class becuase setResult is define inside Activity class

For accessing setResult from non Activity class pass Activity context in Adapter constructor when creating object of Adapter:

private Activity mActivity;
public MyViewHolder(View itemView,Activity mActivity) {
        super(itemView);
        /...your code here..
        this.mActivity=mActivity;
 }

use mActivity for accessing setResult inside onClick of Button

Answer 2

You can use setResult() and finish() by passing activity as a parameter to RecyclerAdapter, then access it using activity.setResult(), activity.finish()
