70.7 Receiving Direct Reply Input

Now that the notification is successfully seeking input from the user, the app needs to do something with that input. The goal of this particular tutorial is to have the text entered by the user into the notification appear on the TextView widget in the activity user interface.

When the user enters text and taps the send button the MainActivity is launched via the intent contained in the PendingIntent object. Embedded in this intent is the text entered by the user via the notification. Within the onCreate() method of the activity, a call to the getIntent() method will return a copy of the intent that launched the activity. Passing this through to the RemoteInput.getResultsFromIntent() method will, in turn, return a Bundle object containing the reply text which can be extracted and assigned to the TextView widget. This results in a modified onCreate() method within the MainActivity.kt file which reads as follows:
