Interface for an EditText subclass that can delegate calls to onKeyPreIme up to a registered listener.
Used in editable actions within
androidx.leanback.app.GuidedStepFragment to allow for custom back key handling. Specifically, this is used to implement the behavior that dismissing the IME also clears edit text focus. Clients who need to supply custom layouts for
GuidedActionsStylist with their own EditText classes should satisfy this interface in order to inherit this behavior.
Listener interface for key events intercepted pre-IME by edit text objects.
Set the listener for this edit text object.
