How to Create a Quiz App In Android?

Last Updated : 15 Jul, 2025

Android is an operating system which is basically made for Mobile phones. It is based on the Linux Kernel and other open-source software and is developed by Google. Android is very popular nowadays among students and students are now choosing Android for their projects. It's very much important for a beginner to build basic Android apps to learn Android Development. In this article let's create a simple Quiz App in Android using Java and Kotlin. A simple Quiz App that contains a set of curated questions and their answers and checks for the score at the end.

Step by Step Implementation Step 1: Creating a new project

To create a new project in the Android Studio, please refer to How to Create/Start a New Project in Android Studio?

Step 2: Working with activity_main.xml

Add the below code in the activity_main.xml file. Here the parent layout is a LinearLayout whose orientation is set to vertical. Inside it, there is one ImageView, one TextView, two Buttons, and two ImageButton. The Button and ImageButton are inside a child LinearLayout for horizontal orientation. ImageView is used for displaying image and TextView is used to display the question and Button is used to indicate true/false and ImageButton for navigating to next/previous question.

activity_main.xml:

activity_main.xml


 <?xml version="1.0" encoding="utf-8"?>
<!--Using linear layout with vertical orientation and center gravity -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:background="#FFFFFF"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    tools:context=".MainActivity">

    <!--ImageView used for showing pictures along with questions-->
    <ImageView
        android:id="@+id/myimage"
        android:layout_width="wrap_content"
        android:src="@drawable/f1"
        android:layout_height="wrap_content"/>

    <!--TextView used for showing questions on screen-->
    <TextView
        android:id="@+id/answer_text_view"
        android:text="@string/a"
        android:textColor="@android:color/black"
        android:textSize="30sp"
        android:padding="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <!--Using another LinearLayout for showing buttons
        in horizontal orientation-->
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <!--TrueButton-->
        <Button
            android:id="@+id/true_button"
            android:layout_marginRight="20dp"
            android:backgroundTint="#5BD91B"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:text="@string/true_text" />

        <!--FalseButton-->
        <Button
            android:id="@+id/false_button"
            android:layout_marginLeft="20dp"
            android:layout_width="wrap_content"
            android:backgroundTint="#E33328"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:text="@string/false_text" />

    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <!--PreviousButton-->
        <ImageButton
            android:id="@+id/prev_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/baseline_keyboard_arrow_left_black_18dp"
            android:backgroundTint="#DFD2D1"
            android:text="@string/prev_text" />

        <!--NextButton-->
        <ImageButton
            android:id="@+id/next_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:backgroundTint="#DFD2D1"
            android:src="@drawable/baseline_keyboard_arrow_right_black_18dp"
            android:text="@string/next_text" />

    </LinearLayout>
</LinearLayout>

Design UI:

Step 3: Working with strings.xml

Navigate to app > res > values > strings.xml and make the following changes. We will be adding 6 questions and fetch them later in MainActivity file.

strings.xml:

XML


 <resources>
    <string name="app_name">Demo</string>

    <string name="a">New Delhi is the capital of India</string>
    <string name="b">West Bengal is located in the west of India</string>
    <string name="c">Arunachal Pradesh is a state of India</string>
    <string name="d">Brazil is located in North America</string>
    <string name="e">HTML is a programming language</string>
    <string name="f">React is a web development framework</string>

</resources>

Step 4: Create a data class for questions

To create a new data class right-click a Java/Kotlin file or folder, and select New > Java/Kotlin Class. Now add the following code in the file.

Question.java


 package org.geeksforgeeks.demo;

public class Question {
    // Resource ID for the question text (stored in strings.xml)
    private int answerResId;
    // Correct answer (true or false)
    private boolean isAnswerTrue;

    public Question(int answerResId, boolean isAnswerTrue) {
        this.answerResId = answerResId;
        this.isAnswerTrue = isAnswerTrue;
    }

    // Getter for answerResId
    public int getAnswerResId() {
        return answerResId;
    }

    // Setter for answerResId
    public void setAnswerResId(int answerResId) {
        this.answerResId = answerResId;
    }

    // Getter for isAnswerTrue
    public boolean isAnswerTrue() {
        return isAnswerTrue;
    }

    // Setter for isAnswerTrue
    public void setAnswerTrue(boolean answerTrue) {
        isAnswerTrue = answerTrue;
    }
}

Question.kt


 package org.geeksforgeeks.demo

data class Question (
    var answerResId: Int,
    var isAnswerTrue: Boolean
)

Step 5: Working with MainActivity file

onCreate() method is invoked first when the app is launched. Question[] array is instantiated with question Id and right answer to the question. setOnClickListener() method is invoked whenever Button/ImageButton is clicked, so when the user clicks a button it checks for its Id by getId() method and performs actions as per our logic. updateQuestion() updates question by settext() method of TextView and changes images by keeping track of question number. checkAnswer() method checks the original answer with the button clicked and uses Toast to display text accordingly.

MainActivity.java


 package org.geeksforgeeks.demo;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    // UI components
    private Button falseButton;
    private Button trueButton;
    private ImageButton nextButton;
    private ImageButton prevButton;
    private TextView questionTextView;
    private TextView answerTextView;

    // Variable to track correct answers
    private int correct = 0;

    // Index to track the current question
    private int currentQuestionIndex = 0;

    // Array holding the questions and their correct answers
    private final Question[] questionBank = {
            new Question(R.string.a, true),
            new Question(R.string.b, false),
            new Question(R.string.c, true),
            new Question(R.string.d, false),
            new Question(R.string.e, false),
            new Question(R.string.f, true)
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        trueButton.setOnClickListener(v -> checkAnswer(true));

        nextButton.setOnClickListener(v -> {
            answerTextView.setVisibility(View.INVISIBLE);

            // Check if there are more questions
            if (currentQuestionIndex < 7) {
                currentQuestionIndex++;

                // If all questions are completed, display the score
                if (currentQuestionIndex == 6) {

                    questionTextView.setText("Your Score: " + correct + "/6");
                } else {
                    updateQuestion();
                }
            }
        });

        prevButton.setOnClickListener(v -> {
            answerTextView.setVisibility(View.INVISIBLE);

            // Prevent going back before the first question
            if (currentQuestionIndex > 0) {
                currentQuestionIndex = (currentQuestionIndex - 1) % questionBank.length;
                updateQuestion();
            }
        });
    }

    // Updates the displayed question
    private void updateQuestion() {
        questionTextView.setText(questionBank[currentQuestionIndex].getAnswerResId());
    }

    // Checks the user's answer and updates the UI
    private void checkAnswer(boolean userChooseCorrect) {
        boolean answerIsTrue = questionBank[currentQuestionIndex].isAnswerTrue();
        String message;

        if (userChooseCorrect == answerIsTrue) {
            message = "That's correct";
            correct++;
        } else {
            message = "That's incorrect";
        }

        // Display feedback message
        answerTextView.setVisibility(View.VISIBLE);
        answerTextView.setText(message);
    }
