Now we shall look into the layout xml file and Activity(Kotlin file) to set OnClickListener for a Button.Ĭreate an Android Application with Kotlin Support and replace activity_main.xml and MainActivity.kt with the following content. In this tutorial, we will learn how to set OnClickListeners for multiple Views and handle them all in one onClickListner method. Example – Kotlin Androide tOnClickListener() The function type is (DialogInterface, Int) -> Unit. The function is a part of the DialogInterface.OnClickListener () interface. Inside the setPositiveButton function, we pass the Button text along with a Kotlin function that’s triggered when that button is clicked.
What we have done here is, we got the reference to the Button and then used setOnClickListener method to trigger an action when the button is clicked. The builder.show () displays the Alert Dialog on the screen. Val btn_click_me = findViewById(R.id.btn_click_me) as Buttonītn_click_me.setOnClickListener "You clicked me.", Toast.LENGTH_SHORT).show()
Following code helps you to set on-click listener for Button.
