I am using Android’s two-way databinding for a form fragment with a the corresponding ViewModel. I am using an Observer object in the ViewModel that extends BaseObservable in order to use the @Bindable annotation and so far it has been working perfectly for TextInputEditTexts and MaterialSwitches. The problem I have now is that when using AutoCompleteTextView (within the TextInputLayout) for a spinner behaviour I can not make it work.
