Dynamic TextView in Kotlin

Android TextView is an user interface that is used to display some text to the user. In this article we will be discussing how to programmatically create a TextView in Kotlin .

Step by Step Implementation

Step 1: Create a new project

Let’s start by first creating a project in Android Studio. To do so, follow these instructions:

• Click on File, then New and then New Project and give name whatever you like
• Then, select Kotlin language Support and click next button.
• Select minimum SDK, whatever you need.
• Select Empty activity and then click finish.

Step 2: Modify activity_main.xml file

Second step is to design our layout page. Here, we will use the RelativeLayout to get the TextView from the Kotlin file.

activity_main.xml:

Step 3: Create TextView in MainActivity.kt file

Navigate to app > src > main > java/kotlin > {package-name} > MainActivity.kt. In this file, we declare a variable TextView to create the TextView widget like this:

val textView = TextView(this)

textView.layoutParams= LinearLayout.LayoutParams(
 ViewGroup.LayoutParams.WRAP_CONTENT,
 ViewGroup.LayoutParams.WRAP_CONTENT
)

then add the widget in layout using this:

layout.addView(textView)

MainActivity File:
