Android is an operating system which is built basically 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 baby Android apps to learn Android. In this article let’s create a simple Quiz App in android using Java. A simple Quiz App that contains a set of curated questions and its answers and checks for the correctness of the answer given by the user. It navigates through the questions using dynamic programming.


Step 1: Creating a new project

  • Click on the File option at the topmost corner in the left.
  • Then click on new and open a new project and name the project.
  • Now select the Empty Activity with language as Java.
  • Name it QuizApp.

Creating a new project

Step 2: Designing the UI 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.

Adding images in the drawable folder:

The following are the links given for all the drawable files that are used in this project.

  • For flower images (f1/f2/f3/f4/f5/f6/f7): Refer to this.
  • For the next icon: Refer to this.
  • For the previous icon: Refer to this.
  • For emoji: Refer to this.

The complete code for the activity_main.xml file is given below.


<?xml version="1.0" encoding="utf-8"?>
<!--Using linear layout with vertical orientation and center gravity -->
<LinearLayout xmlns:android=""
    <!--ImageView used for showing pictures along with questions-->
    <!--TextView used for showing questions on screen-->
    <!--Using another LinearLayout for showing buttons
        in horizontal orientation-->
            android:text="@string/true_text" />
            android:text="@string/false_text" />
            android:text="@string/prev_text" />
            android:text="@string/next_text" />

After adding this code in activity_main.xml the UI looks like:

Step 3: Working with 

To create a new Java class right-click a Java file or folder, and select New > Java Class

Now add the following code in the Here use getters and setters method to retrieve and set data. Method isAnswerTrue() returns answerTrue as already passed in Question Constructor.

package org.geeksforgeeks.quizapp;
public class Question
    // answerResId will store question
    private int answerResId;
    // answerTrue will store correct answer
    // of the question provided
    private boolean answerTrue;
    public Question(int answerResId, boolean answerTrue)
      // setting the values through
      // arguments passed in constructor
      this.answerResId = answerResId;
      this.answerTrue = answerTrue;
    // returning the question passed
    public int getAnswerResId() 
      return answerResId; 
    // setting the question passed
    public void setAnswerResId(int answerResId)
      this.answerResId = answerResId;
    // returning the correct answer
    // of question
    public boolean isAnswerTrue() 
      return answerTrue; 
    // setting the correct
    // ans of question
    public void setAnswerTrue(boolean answerTrue)
      this.answerTrue = answerTrue;

Step 4: Working with strings.xml file

In the strings.xml file, we have to provide the question bank. One can add many questions inside this file.


    <!--All the string resources come here including Questions and title -->
    <string name="app_name">GFG | HOW WELL DO YOU KNOW SIMRAN?</string>
    <string name="correct"><b>CORRECTNESS IS</b> \n
                           <b>%1$d</b> OUT OF 6</string>
    <string name="true_text">true</string>
    <string name="false_text">false</string>
    <string name="correct_answer">That\'s correct</string>
    <string name="wrong_answer">That\'s incorrect</string>
    <string name="a">Simran loves Chocolates.</string>
    <string name="b">Simran Knows Following Skills:\n \t
                     <b>Ballet</b>\n \t
    <string name="c">Do You Think Simran Believes In:\n \t
    <string name="d">Do You Think Simran Wants To Visit <b>Italy</b></string>
    <string name="e">Simran Loves Loyalty.</string>
    <string name="f">Simran Sleeps Less</string>
    <string name="next_text">next</string>
    <string name="prev_text">previous</string>


Step 5: Working with

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.
