By default, the notification's text content is truncated to fit one line. If you want your notification to be longer, for example, to create a larger text area, you can do it in this way:

• A.  var builder = NotificationCompat.Builder(this, CHANNEL_ID)
  .setContentText("Much longer text that cannot fit one line...")
  .setStyle(NotificationCompat.BigTextStyle()
  .bigText("Much longer text that cannot fit one line..."))
  ...
• B.  var builder = NotificationCompat.Builder(this, CHANNEL_ID)
  .setContentText("Much longer text that cannot fit one line...")
  .setLongText("Much longer text that cannot fit one line..."))
  ...
• C.  var builder = NotificationCompat.Builder(this, CHANNEL_ID)
  .setContentText("Much longer text that cannot fit one line...")
  .setTheme(android.R.style.Theme_LongText);
  ...

In general, you should send an AccessibilityEvent whenever the content of your custom view changes. For example, if you are implementing a custom slider bar that allows a user to select a numeric value by pressing the left or right arrows, your custom view should emit an event of type TYPE_VIEW_TEXT_CHANGED whenever the slider value changes. Which one of the following sample codes demonstrates the use of the sendAccessibilityEvent() method to report this event.

• A.  override fun onKeyUp(keyCode: Int, event: KeyEvent): Boolean { return when(keyCode) { KeyEvent.KEYCODE_ENTER -> { currentValue-- sendAccessibilityEvent (AccessibilityEvent.TYPE_VIEW_CONTEXT_CLICKED) true
  }
  ...
  }
  }
• B.  override fun onKeyUp(keyCode: Int, event: KeyEvent): Boolean { return when(keyCode) { KeyEvent.KEYCODE_DPAD_LEFT -> { currentValue-- sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED) true
  }
  ...
  }
  }
• C.  override fun dispatchPopulateAccessibilityEvent(event: AccessibilityEvent): Boolean { return super.dispatchPopulateAccessibilityEvent(event).let { completed -> if (text?.isNotEmpty() == true) { event.text.add(text) true
  } else {
  completed
  }
  }
  }
