[android] Handle Button click inside a row in RecyclerView

I find that typically:

• I need to use multiple listeners because I have several buttons.
• I want my logic to be in the activity and not the adapter or viewholder.

So @mark-keen's answer works well but having an interface provides more flexibility:

public static class MyViewHolder extends RecyclerView.ViewHolder {

    public ImageView iconImageView;
    public TextView iconTextView;

    public MyViewHolder(final View itemView) {
        super(itemView);

        iconImageView = (ImageView) itemView.findViewById(R.id.myRecyclerImageView);
        iconTextView = (TextView) itemView.findViewById(R.id.myRecyclerTextView);

        iconTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onClickListener.iconTextViewOnClick(v, getAdapterPosition());
            }
        });
        iconImageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onClickListener.iconImageViewOnClick(v, getAdapterPosition());
            }
        });
    }
}

Where onClickListener is defined in your adapter:

public MyAdapterListener onClickListener;

public interface MyAdapterListener {

    void iconTextViewOnClick(View v, int position);
    void iconImageViewOnClick(View v, int position);
}

And probably set through your constructor:

public MyAdapter(ArrayList<MyListItems> newRows, MyAdapterListener listener) {

    rows = newRows;
    onClickListener = listener;
}

Then you can handle the events in your Activity or wherever your RecyclerView is being used:

mAdapter = new MyAdapter(mRows, new MyAdapter.MyAdapterListener() {
                    @Override
                    public void iconTextViewOnClick(View v, int position) {
                        Log.d(TAG, "iconTextViewOnClick at position "+position);
                    }

                    @Override
                    public void iconImageViewOnClick(View v, int position) {
                        Log.d(TAG, "iconImageViewOnClick at position "+position);
                    }
                });
mRecycler.setAdapter(mAdapter);
