Expandable Text in Android using Jetpack Compose
Many applications display tons of textual data in form of passages and have the feature of expanding or contracting it. Generally, 2-3 out of n lines of a passage are displayed along with “View More”, “Read More”, and “…” at the end. These appear like hyperlinks that upon click expand the text to full.
So in this article, we will show you how you could create an expandable text in Android using Jetpack Compose. Follow the below steps once the IDE is ready.
Step by Step Implementation
Step 1: Create a New Project in Android Studio
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. While choosing the template, select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version. We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project.
Step 2: Working with the MainActivity.kt file
Go to the MainActivity.kt file and refer to the following code. Below is the code for the MainActivity.kt file. Comments are added inside the code to understand the code in more detail.
You can see that we are successfully able to implement expandable text in our application.
