I have come across some tutorials using switch statements to make quiz app by using radio buttons, but I intend to use buttons but not radio buttons to do this... Can I? I want the user to be able to play the quiz app by clicking buttons but not radio buttons. Please guide me through!! Thanks in advance!

The tutorials I mentioned is as below:

MainActivity,java file code

package com.example.ab.quiz;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.RadioButton;

import android.widget.RadioGroup;

import android.widget.TextView;



public class MainActivity extends AppCompatActivity {

EditText ed1;

TextView tv1,tv2,tv3;

RadioButton a,b,c,d;

Button bt;

RadioGroup rg;

int q,s;



@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    ed1=(EditText)findViewById(R.id.name);

    tv1=(TextView)findViewById(R.id.ques);

    tv2=(TextView)findViewById(R.id.response);

    tv3=(TextView)findViewById(R.id.score);

    rg=(RadioGroup)findViewById(R.id.optionGroup);

    a=(RadioButton)findViewById(R.id.option1);

    b=(RadioButton)findViewById(R.id.option2);

    c=(RadioButton)findViewById(R.id.option3);

    d=(RadioButton)findViewById(R.id.option4);

    bt=(Button)findViewById(R.id.next);

    q=0;

    s=0;



}

public void quiz(View v){

    switch (q){

        case 0:

        {

            rg.setVisibility(View.VISIBLE);

            a.setChecked(false);
