Kotlin Android – Selectable Text in TextView
To enable text in TextView for selection, set android:textIsSelectable attribute to “true” for the TextView widget in layout XML file.
<TextView ... android:textIsSelectable="true" />
A behavior of selectable text in TextView would look like as shown in the following screenshot.

Example
In this example, we will create an Android Application with a TextView, and make the text in the TextView selectable.
Create an Android Application with an Empty Activity.

In the main activity layout file, create a TextView as shown in the following code.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:gravity="center" android:layout_height="wrap_content"> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textIsSelectable="true" android:textSize="30sp" android:padding="20sp" android:text="Hello World" /> </LinearLayout>
No changes are required in MainActivity.kt file.
MainActivity.kt
package com.example.myapplication import androidx.appcompat.app.AppCompatActivity import android.os.Bundle class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) } }
Run this Android Application and you should get the TextView displayed with text enabled for selection.

Double tap or long press on the text of TextView and a selection with options appears as shown in the following screenshot.

Conclusion
In this Kotlin Android Tutorial, we learned how to enable text in TextView for selection.
