Introduction Jetpack Compose is a modern toolkit for building native Android UI, designed to simplify and accelerate UI development with Kotlin. One of the most powerful aspects of Jetpack Compose is how it allows developers to define UI components declaratively and manage state efficiently. In this article, we will explore an Android Kotlin example that demonstrates the use of combinedClickable in Jetpack Compose. The example showcases how different types of click interactions—single click, double click, and long press—can be handled within a single composable function to create a responsive and interactive UI. This tutorial is perfect for developers who are familiar with the basics of Jetpack Compose but want to take a deeper dive into handling multiple types of gestures with combinedClickable . By the end of this breakdown, you’ll understand how to implement gesture handling in a clean and readable way using Compose's modern features. Setting Up the Main Activity The entry poin...

This code demonstrates how to apply various types of brushes to create backgrounds in Jetpack Compose. It showcases solid color brushes with different shapes and transparency, as well as a horizontal gradient brush with rounded corners. Breakdown of the Code The code is structured within the MainActivity class. The onCreate function sets the content using setContent { GetScaffold() } . This calls the GetScaffold composable which builds the overall layout with a Scaffold element. GetScaffold composes a top bar using TopAppBar and sets the content with MainContent . MainContent defines a vertical column with centered elements and spacing. It then creates three Box composables, each demonstrating a different background brush usage. Background Brush Examples: The first box uses a SolidColor brush with a light gray color, rectangular shape, and 50% transparency (alpha 0. 5F). The second box also uses a SolidColor brush, but with a blue color, rounded corner shape wit...
