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; } } 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); // Initializing UI elements falseButton = findViewById(R.id.false_button); trueButton = findViewById(R.id.true_button); nextButton = findViewById(R.id.next_button); prevButton = findViewById(R.id.prev_button); questionTextView = findViewById(R.id.question); answerTextView = findViewById(R.id.answer); // Hide the answer text initially answerTextView.setVisibility(View.INVISIBLE); // Load the first question updateQuestion(); // Button click listeners falseButton.setOnClickListener(v -> checkAnswer(false)); 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) { nextButton.setVisibility(View.GONE); prevButton.setVisibility(View.GONE); trueButton.setVisibility(View.GONE); falseButton.setVisibility(View.GONE); 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); } } 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.activity.enableEdgeToEdge import androidx.appcompat.app.AppCompatActivity import androidx.core.view.ViewCompat import androidx.core.view.WindowInsetsCompat class MainActivity : AppCompatActivity() { // UI components private lateinit var falseButton: Button private lateinit var trueButton: Button private lateinit var nextButton: ImageButton private lateinit var prevButton: ImageButton private lateinit var questionTextView: TextView private lateinit var answerTextView: TextView // Variable to track the correct answers private var correct = 0 // Index to track the current question private var currentQuestionIndex = 0 // Array holding the questions and their correct answers private val questionBank: Array<Question> = arrayOf( Question(R.string.a, true), Question(R.string.b, false), Question(R.string.c, true), Question(R.string.d, false), Question(R.string.e, false), Question(R.string.f, true), ) override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) enableEdgeToEdge() setContentView(R.layout.activity_main) // Adjust layout to fit system UI elements ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main)) { v, insets -> val systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars()) v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom) insets } // Initializing UI elements falseButton = findViewById(R.id.false_button) trueButton = findViewById(R.id.true_button) nextButton = findViewById(R.id.next_button) prevButton = findViewById(R.id.prev_button) questionTextView = findViewById(R.id.question) answerTextView = findViewById(R.id.answer) // Hide the answer text initially answerTextView.visibility = View.INVISIBLE // Load the first question updateQuestion() // Button click listeners falseButton.setOnClickListener { checkAnswer(false) } trueButton.setOnClickListener { checkAnswer(true) } nextButton.setOnClickListener { answerTextView.visibility = View.INVISIBLE // Check if there are more questions if (currentQuestionIndex < 7) { currentQuestionIndex += 1 // If all questions are completed, display the score if (currentQuestionIndex == 6) { nextButton.visibility = View.GONE prevButton.visibility = View.GONE trueButton.visibility = View.GONE falseButton.visibility = View.GONE questionTextView.text = "Your Score: $correct/6" } else { updateQuestion() } } } prevButton.setOnClickListener { answerTextView.visibility = View.INVISIBLE // Prevent going back before the first question if (currentQuestionIndex > 0) { currentQuestionIndex = ((currentQuestionIndex - 1) % questionBank.size) updateQuestion() } } } // Updates the displayed question private fun updateQuestion() { questionTextView.setText(questionBank[currentQuestionIndex].answerResId) } // Checks the user's answer and updates the UI private fun checkAnswer(userChooseCorrect: Boolean) { val answerIsTrue = questionBank[currentQuestionIndex].isAnswerTrue val message: String if (userChooseCorrect == answerIsTrue) { message = "That's correct" correct++ } else { message = "That's incorrect" } // Display feedback message answerTextView.visibility = View.VISIBLE answerTextView.text = message } }
