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

Problem

In my app i need to start RecyclerAdapter.class and wait for result, but i cant write lines setResult and finish: ``` public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { TextView title; ImageView icon; public MyViewHolder(View itemView) { super(itemView); title = (TextView) itemView.findViewById(R.id.list_title); icon = (ImageView) itemView.findViewById(R.id.list_item); icon.setOnClickListener(this); } @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()) { case 0: selectedCountry = "ukr"; Log.i ("1" ,"" +selectedCountry); Intent intent= new Intent(); intent.putExtra("country", selectedCountry); break; case 1: selectedCountry = "by"; Log.i ("1" ,"" +selectedCountry); break; case 2: selectedCountry = "rus"; Log.i ("1" ,"" +selectedCountry); break; case 3: selectedCountry = "nrus"; Log.i ("1" ,"" +selectedCountry); break; } //intent. putExtra("country") } } ``` how i need to write it?Please help me and explain what i do wrong I need to setResult from all my cases 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()) { case 0: selectedCountry = "ukr"; Log.i("1", "" + selectedCountry); Intent intent = new Intent(); intent.putExtra("country", selectedCountry); mActivity.setResult(mActivity.RESULT_OK, intent); mActivity.finish(); break; case 1: selectedCountry = "by"; Log.i("1", "" + selectedCountry); break; case 2: selectedCountry = "rus"; Log.i("1", "" + selectedCountry); break; case 3: selectedCountry = "nrus"; Log.i("1", "" + selectedCountry); break; } } } ``` }
