We’ve arranged them horizontally in four layers. This will be for the users to interact with our calculator. So to create the interface we’ve added the number button and the operators for the calculator.

Now, we’ll see what’s there in the code to understand it better.

Please download the source code: Android calculator source code

First of all, you would need to download the code.

So let us see the required files & steps for the code:

Throughout this article, we’ll understand the usage and working of the code before we implement it. Now we’ll begin with the development of a simple calculator app. Android virtual device is also shipped with android studio that will be helpful in testing whether the applications are working or notĭevelop a Simple Calculator App in Android Studio Android Studio: Android Studio is the backbone of our application, as we will develop our app using android studio.It will be used for the development of the user interface for the application XML: XML is another important part of our android application.Java programming plays a very important role as we will develop the app code in Java Java: First of all you need to have the knowledge of Java Programming.To develop this simple calculator app the requirements and prerequisites are as follows: This calculator app would be a one time install once the user installs it they are always ready to use it.Then, there will be a screen that will show the number entered by the user and result when they click on answer.Then we’ll have to create two more buttons for the delete and answer buttons.Another thing would be operators like +, *, /, -, % that are created using buttons too.It will have the number keys that will be created using buttons.Let us go through its description about what things the user interface will have:

For the development of this application, we will make use of Android Studio. This android application will have a user interface with numbers and arithmetic operations. This is a basic project for beginners, the android calculator app will help us to do various arithmetic calculations. What is our simple calculator project all about? Okay, now let us begin with our project without any further delay!! The first calculator was invented in the year 1642 by Blaise Pascal when he was 19 years old. We’ll understand the complete project development in this article.ĭo you know when was the first ever mechanical calculator created? The Calculators that we use today were never the same earlier. Today we are going to see and learn to implement an Android Project that is a simple calculator app in android studio. Hey there Android enthusiasts, greetings from DataFlair.
