Toast Does Not Display when I click a row

Android Programming (3rd Edition) 8. Displaying Lists with RecyclerView
1

My Toast does not appear in response to code:

private class CrimeHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        public TextView mTitleTextView;
        private TextView mDateTextView;
        private CheckBox mSolvedCheckBox;
        private Crime mCrime;
        public CrimeHolder(View itemView) {
            super(itemView);
            mTitleTextView = itemView.findViewById(R.id.list_item_crime_title_text_view);
            mDateTextView = itemView.findViewById(R.id.list_item_crime_date_text_view);
            mSolvedCheckBox = itemView.findViewById(R.id.list_item_crime_solved_check_box);
        }
        public void bindCrime(Crime crime) {
            mCrime = crime;
            mTitleTextView.setText(mCrime.getTitle());
            mDateTextView.setText(mCrime.getDate().toString());
            mSolvedCheckBox.setChecked(mCrime.isSolved()); }

        @Override
        public void onClick(View v) {
            Toast.makeText(getActivity(), mCrime.getTitle() + " clicked!", Toast.LENGTH_SHORT).show();
        }
    }

Any help would be appreciated.

Hello,

You must implement the “setOnClickListener()”. So, you can write it like this:

 public CrimeHolder(View itemView) {
            super(itemView);
            mTitleTextView = itemView.findViewById(R.id.list_item_crime_title_text_view);
            mDateTextView = itemView.findViewById(R.id.list_item_crime_date_text_view);
            mSolvedCheckBox = itemView.findViewById(R.id.list_item_crime_solved_check_box);
            itemView.setOnClickListener(this);   ---> important !
        }
