TextView Implementation in Kotlin

Android app development, the TextView plays a crucial role in presenting textual information to the user. Whether it’s displaying static text, dynamic content, or even richly formatted text, the TextView is an indispensable user interface component.

A simple XML code of TextView in a layout is shown below.

mainactivity.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/text_view_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hi, How are you ?" />

</LinearLayout>

TextView supports multiline text display and provides options for controlling text wrapping and truncation.

We’ll demonstrate how to set the maximum number of lines, enable scrolling for long text, and implement ellipsis for text that exceeds the available space.

Additionally, we’ll explore the use of scrollable TextView containers for displaying large amounts of text. Now Please check below kotlin code.

MainActivity.kt

import android.os.Bundle
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
    private lateinit var textView: TextView

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        textView = findViewById(R.id.textView)

        val content = "Welcome to Kotlin TextView!"
        textView.text = content
    }
}
