I have a registration activity and a dialog fragment. Every time I press a button from registration activity, a dialog fragment with a button shows up, web service is called when the button is pressed. What I want to do is, I want to get the TextInputLayout from registration activity to my dialog fragment because if there's a web service error in one of the fields I want to use setError() to display that error. I've tried using an LayoutInfater to inflate the view, i don't get any error when I run the code but I also don't see inline error in my TextInputLayout.
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.activity_register, null);
Is it possible? Any help would be greatly appreciated.
You should never pass views from one activity/fragment to other activities/fragments!
In your case, its better to use a mechanism to pass result of API call from your dialog fragment to activity. In this case there are multiple ways; one is to use a SharedViewModel between your dialog and activity. Another one is to use FragmentResult API to pass result of the API call to activity.
