How To Use TextView In Kotlin

In Kotlin, TextView is a fundamental UI component used to display and manipulate text in Android applications. It is part of the Android framework and is commonly used to present textual information to the user.

To use a TextView in Kotlin, you typically follow these steps: Define a TextView in your XML layout file:

<TextView
    android:id="@+id/myTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello, World!" />

In your Kotlin code, access the TextView using its ID:

val myTextView = findViewById<TextView>(R.id.myTextView)

Note: If you're using Kotlin Android Extensions or View Binding, you can skip the findViewById step and directly reference the TextView by its ID. Manipulate the TextView as needed. For example, you can change the text dynamically:

myTextView.text = "Welcome to Kotlin"

You can also apply various styling attributes to TextView, such as text color, font size, alignment, etc., using XML attributes or programmatically. Additionally, you can handle events like clicks on the TextView by setting an OnClickListener or performing other interactions as required in your app.

textView?.setOnClickListener{ Toast.makeText(this@MainActivity,
                "You Click on Textview", Toast.LENGTH_LONG).show() }

By leveraging the capabilities of TextView, you can create dynamic and interactive user interfaces in your Kotlin-based Android applications, effectively displaying and managing textual content for an enhanced user experience.
