Question

I am using recyclerview in my android app and i want to show ads in my app, i know how to show ads but what i want to do is get recyclerview item count so if a user clicks on say e.g two items i want to show admob interstitial ad. I searched a lot but couldn't figure it out Here is my code

    public class DictionaryAdapter extends RecyclerView.Adapter <DictionaryAdapter.ViewHolder> {
     private Cursor cursor;

    public DictionaryAdapter() {

    }

    public void setCursor(Cursor cursor) {
        this.cursor = cursor;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int position) {

        Context context = parent.getContext();
        LayoutInflater inflater = LayoutInflater.from(context);

        View v = inflater.inflate(R.layout.dictionary_item_layout, parent, false);
        ViewHolder viewHolder = new ViewHolder(v, context);
        return viewHolder;
    }

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

        cursor.moveToPosition(position);
        holder.word.setText(cursor.getString(1));
    }

    @Override
    public int getItemCount() {
        if (cursor == null) return 0;
        return cursor.getCount();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        Context context;
        TextView word;

        public ViewHolder(@NonNull View itemView, final Context context) {
            super(itemView);

            this.context = context;
            word = itemView.findViewById(R.id.wordText);
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    int position = getAdapterPosition();
                    cursor.moveToPosition(position);

                    Intent intent = new Intent(context, DetailActivity.class);
                    intent.putExtra("ID", cursor.getString(0));
                    intent.putExtra("WORD", cursor.getString(1));
                    intent.putExtra("DEFINITION", cursor.getString(2));
                    context.startActivity(intent);


                }
            });

        }
    }
}

Here is how i get it my main activity

 preferences = getSharedPreferences("click_count",MODE_PRIVATE);
        if (preferences.getInt("count", 0) > 2) {
            mInterstitialAd = new InterstitialAd(this);
            mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
            mInterstitialAd.loadAd(new AdRequest.Builder().build());
            mInterstitialAd.setAdListener(new AdListener() {
                public void onAdLoaded() {
                    if (mInterstitialAd.isLoaded()) {
                        mInterstitialAd.show();
                    }
                }
            });


            editor = preferences.edit();
            editor.clear();
            editor.apply();
        }

You can simply save your clicks count in SharedPreference. First pass context to your Adapter.

private Context mContext;

 public DictionaryAdapter(Context mContext) {
    this.mContext = mContext;
    }

Then add the below methods to the adapter:

private void addClick(Context mContext) {
    int click = getClicksCount(mContext)+1;
    SharedPreferences preferences = mContext.getSharedPreferences("click_count", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putInt("count", click);
    editor.apply();
}

private int getClicksCount(Context mContext){
    SharedPreferences preferences = mContext.getSharedPreferences("click_count",Context.MODE_PRIVATE);
    return preferences.getInt("count",0);
}

And finally, use them. Your itemView clickListener will be like:

itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    addClick(mContext);
                    int position = getAdapterPosition();
                    cursor.moveToPosition(position);

                    Intent intent = new Intent(context, DetailActivity.class);
                    intent.putExtra("ID", cursor.getString(0));
                    intent.putExtra("WORD", cursor.getString(1));
                    intent.putExtra("DEFINITION", cursor.getString(2));
                    context.startActivity(intent);


                }
            });

You can get click counts by calling int count = getClicksCount(mContext); methode.
