setView - used to add a custom view inside the alert dialog. 
setPositiveButton - We pass the string name, as well as Button, clicked callback method here. setCustomTitle - Here you can pass a custom view that’ll be put in place of the title part in the alert dialog. Some of the methods that can be used on an AlertDialog. Optionally, we can pass another parameter, the alert dialog style. We pass the context inside the constructor. val alertDialogBuilder = AlertDialog.Builder(this) To create an AlertDialog we use the AlertDialog.Builder inner class. Buttons - There are three types of buttons: Positive, Negative, and Neutral. There are three core components that build an Alert Dialog. They generally show some information and ask for a user action. Alert DialogsĪlert Dialog is a window that pops up on the screen. In this tutorial, we’ll be discussing Alert Dialogs and implement them in our Android Application using Kotlin. You must use this ID to inflate the layout from the XML: private void displayToast ( String message ) Īnd then you can display the custom toast using displayToast("Message"). Notice that the ID of the LinearLayout element is "toast_layout_root". First, simply define the XML view in res/layout in a file such as toast_layout.xml: You can also create a Toast that uses a custom XML layout rather than just displaying plain text. 
makeText ( applicationContext, "some message", Toast. makeText ( getApplicationContext (), "some message", Toast. You can change this position with the setGravity method and specifying a Gravity constant. A standard toast notification appears near the bottom of the screen, centered horizontally. You can configure the position of a Toast. show () // also supports Toast.LENGTH_LONG also supports Toast.LENGTH_LONG Toast. This method takes three parameters: the application Context, the text message, and the duration for the toast. Toasts automatically disappear after a timeout.įirst, instantiate a Toast object with one of the makeText() methods. It only fills the amount of space required for the message and the current activity remains visible and interactive. A toast provides simple feedback about an operation in a small popup.
