Using Kotlin Anko Library for Android Development

Kotlin Anko is a powerful library that simplifies Android app development by providing a concise and expressive way to create user interfaces and perform common tasks. In this guide, we'll explore how to use Kotlin Anko for Android app development.

Adding Anko to Your Project

To start using Kotlin Anko, you need to add the Anko library to your project's dependencies. Add the following lines to your app's build.gradle file:

dependencies {
implementation "org.jetbrains.anko:anko:$anko_version"

Make sure to replace `$anko_version` with the version of Anko you want to use.

Creating User Interfaces

Anko simplifies UI creation. Here's how you can define a simple UI using Anko:

class MyActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {

verticalLayout {
padding = dip(16)

val name = editText {
hint = "Name"

button("Submit") {
onClick { toast("Hello, ${name.text}!") }

In this code, we use Anko's DSL to create a vertical layout containing an EditText and a Button. The `onClick` function of the Button displays a toast message.

Working with Dialogs

Anko simplifies creating and displaying dialogs. Here's an example of creating a confirmation dialog:

alert("Delete Item", "Are you sure you want to delete this item?") {
yesButton { /* Delete the item */ }
noButton { /* Cancel deletion */ }

Anko's DSL allows you to create and customize dialogs with ease.


Kotlin Anko is a valuable library for Android developers looking to streamline UI creation and common tasks. With Anko, you can write Android code in a more concise and expressive manner, making your development process more efficient and enjoyable.

Happy coding with Kotlin Anko!
