Use the custom RecyclerView application, consisting of one textView and three radioButton.
When you press any radioButton, an audio file is played.

Notes:

When I use MeidaPlayer
Inside RecyclerView
The application does not work

Code class MainActivity

public class MainActivity extends AppCompatActivity {



private String question = {

        "The capital of France",

        "The capital of India",

        "The capital of Iraq"

};

private String answer1 = {"Paris", "New Delhi", "Baghdad" };

private String answer3 = {"Canberra", "Manama", "Brasilia" };

private String answer2 = {"Havana", "Doha", "Moscow" };



///////////////////////////////



protected void onCreate(Bundle savedInstanceState) {

    setContentView(R.layout.activity_main);

    super.onCreate(savedInstanceState);



    addQuestion();



}



//////////////////////////////



public void addQuestion() {



    List<Question> questionsList = new ArrayList<>();

    RecyclerView recyclerView = findViewById(R.id.recycler);

    recyclerView.setLayoutManager(new LinearLayoutManager(this));



    for (int i = 0; i < question.length; i++) {



        String item0 = question[i];

        String item1 = answer1[i];

        String item2 = answer2[i];

        String item3 = answer3[i];



        Question questionClass = new Question(item0, item1, item2, item3);



        questionsList.add(questionClass);



    }



    QuesAdapter adapter = new QuesAdapter(questionsList);

    recyclerView.setAdapter(adapter);



}



}

This class is intended to add menu items

public class Question {



final String question, answer_1, answer_2, answer_3;



public Question(String question, String answer_1, String answer_2, String answer_3) {



    this.question = question;

    this.answer_1 = answer_1;

    this.answer_2 = answer_2;

    this.answer_3 = answer_3;



}



}

This class is for the RecyclerView custom list
Here's the problem
If the button is pressed
I want to play a sound file

public class QuesAdapter extends RecyclerView.Adapter<QuesAdapter.QuesHolder> 

{



private List<Question> questionList;



public QuesAdapter(List<Question> questionList) {

    this.questionList = questionList;

}



@Override

public QuesHolder onCreateViewHolder(ViewGroup viewGroup, int i) {



    View row = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.question, viewGroup, false);



    QuesHolder holder = new QuesHolder(row);



    return holder;

}



@Override

public void onBindViewHolder(QuesHolder viewHolder, int i) {



    Question question = questionList.get(i);



    TextView ques = viewHolder.question;

    final RadioButton answer1 = viewHolder.answer1;

    RadioButton answer2 = viewHolder.answer2;

    RadioButton answer3 = viewHolder.answer3;



    ques.setText(question.question);

    answer1.setText(question.answer_1);

    answer2.setText(question.answer_2);

    answer3.setText(question.answer_3);



    /////////////////////////////

    // Start: this is the problem

    // Press the button An audio file is playing

    answer1.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View v) {



            Log.i("TAG", answer1.getText() + "");



        }

    });

    // End: this is the problem

    ///////////////////////////



}



@Override

public int getItemCount() {

    return questionList.size();

}



class QuesHolder extends RecyclerView.ViewHolder {



    private TextView question;

    private RadioButton answer1, answer2, answer3;



    public QuesHolder(View itemView) {

        super(itemView);



        question = itemView.findViewById(R.id.question);

        answer1 = itemView.findViewById(R.id.answer_1);

        answer2 = itemView.findViewById(R.id.answer_2);

        answer3 = itemView.findViewById(R.id.answer_3);



    }

}

}

Put your sound file inside the raw folder in res directory, you probably would have to make raw folder in res because it is not present when you create project and

final MediaPlayer mp = MediaPlayer.create(this, R.raw.sound);

answer1.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View v) {

        mp.start();

        Log.i("TAG", answer1.getText() + "");



    }

});
