Today I Built a Calculator App

Himanshu Gaur — Tue, 11 Feb 2025 16:11:39 +0000

Today was a milestone in my coding journey as I successfully built a simple calculator that can perform basic arithmetic operations like addition, subtraction, multiplication, and division. This project not only improved my understanding of layouts in XML but also sharpened my skills in building user interfaces (UI) using XML. Here's a rundown of my experience and what I learned along the way.

Diving into XML Layouts
The first step in building my calculator was designing the layout. I spent a considerable amount of time understanding how to structure and organize the UI components using XML. Learning to work with different layout types such as LinearLayout and RelativeLayout was a significant part of this process. I found that mastering XML layouts is crucial for creating visually appealing and functional interfaces.

Making Buttons Work with OnClickListener
Once the layout was set, the next challenge was to make the buttons functional. This involved learning about the OnClickListener in Android development. By implementing OnClickListener, I was able to define what actions should be taken when each button is pressed. This part of the project was particularly exciting as it brought my calculator to life, allowing it to respond to user interactions.

Implementing Arithmetic Operations
With the layout and button functionalities in place, the core of the calculator—performing arithmetic operations—was next. I wrote the logic for addition, subtraction, multiplication, and division, ensuring that each operation works seamlessly. It was a great exercise in honing my problem-solving skills and understanding the flow of data within the app.

Reflections and Future Goals
Building this calculator was a rewarding experience that taught me a lot about XML layouts and UI development. It also reinforced the importance of attention to detail, especially when it comes to coding user interactions.

My Android Development Journey: Mastering XML & Embracing Jetpack Compose

Himanshu Gaur — Thu, 06 Feb 2025 13:07:35 +0000

Today marks an exciting milestone in my Android development journey! I delved into the world of XML (Extensible Markup Language), which has long been the backbone of designing user interfaces in Android applications. While Google is now shifting towards Jetpack Compose—a modern and declarative UI toolkit—understanding XML remains a crucial skill for any Android developer.

Understanding XML Layouts
XML is used to structure the UI elements of an app. It provides a clear, hierarchical representation of views and components that make up the user interface. One of the most important aspects of XML layouts is the ability to assign unique IDs to elements. These IDs help us reference UI components in our Kotlin or Java code, enabling interaction with buttons, text fields, and other views.

Exploring ConstraintLayout and LinearLayout
During my learning session, I explored two commonly used layout structures:

ConstraintLayout: A powerful and flexible layout that allows positioning elements relative to each other or to the parent container. It’s highly recommended for complex UI designs as it reduces the nesting of views, improving performance.

LinearLayout: A simpler layout that arranges UI components in a horizontal or vertical order. While easy to use, excessive nesting can impact performance.

UI Development: Side Window vs. Manual Coding
Android Studio provides a side window where we can visually design UI components using drag-and-drop functionality. However, relying too much on this feature isn't considered best practice. Writing XML manually gives us greater control and a deeper understanding of the UI structure.

My First XML-Based App: Age Calculator
To apply my newfound knowledge, I built a simple Age Calculator app! The app allows users to select their birthdate using a DatePickerDialog and calculates their age in minutes. This project was a great way to reinforce my learning and experiment with UI elements and event handling.

Jetpack Compose vs. XML: A Comparison
With Google’s push toward Jetpack Compose, it’s important to understand how it compares with XML-based UI development:

Syntax & Readability: Jetpack Compose uses a declarative Kotlin-based approach, making UI code more readable and concise, whereas XML requires separate layout files.

Performance: Jetpack Compose can be more efficient as it eliminates the need for complex view hierarchies, while XML layouts rely on ViewGroups, which can impact performance.

Flexibility: Jetpack Compose allows dynamic UI updates with less boilerplate code, whereas XML-based UIs require modifying Views manually.

Learning Curve: XML is well-established, and many developers are already familiar with it, while Jetpack Compose introduces new concepts that may require some learning.

Interoperability: Both XML and Jetpack Compose can be used together in the same project, making the transition smoother for developers.

Looking Ahead
As I continue my Android development journey, I’m excited to explore Jetpack Compose and compare it with XML-based UI development. The shift to a more intuitive, Kotlin-based UI design approach will be an interesting experience.

Stay tuned for more updates as I dive deeper into Android development!
Happy Coding!

Step 3: Designing the Location Selection Screen

I then crafted the LocationSelectionScreen, a crucial part of the app where users can set the location for their shopping needs. This screen provides an intuitive interface where users can interact with a map to select their desired location.

Step 4: Enhancing the Alert Dialog

In this step, I added an Address button within an alert dialog to allow users to set their location on Google Maps. This feature enhances the user experience by offering a seamless way to pinpoint and select addresses directly from the map.

Step 5: Navigating Android Composable and Location Services

Finally, I delved into Android Composable and Location Services. Navigating through these advanced topics allowed me to efficiently manage and implement location-based features in my app, bringing a layer of interactivity and real-world relevance to the user experience.

Reflecting on Today's Lecture

Today's lesson was incredibly rewarding as I applied the concepts of Location from our previous video to build a more dynamic and user-centric Shopping List app. Sir Denis Panjuta's instruction was, as always, invaluable. His expert guidance on integrating Google Maps into our application opened my eyes to new possibilities and the practical implementation of theoretical knowledge.

In summary, today's advancements in my Shopping List app were a testament to the power of combining maps, location services, and effective data management. I look forward to the next steps in this journey and further enriching my development skills.
