I'm trying to validate my login but every time I press the login button an "app keeps stopping" error appears.

All,

I'm building a media player using Amazon Corretto 11 library and OpenJFX. I have this issue that's keeping me on the struggle. Still a newbie in Java, it will be much appreciated if someone can help me out on this.

I have created a custom class that extends from the MaterialCardView class, to which I add a TextView programmatically like this:

I'm trying to use ViewBinding in the new module I added to the project that will contain all the CustomViews in the project.

This module at this moment is the only one that will implement the viewbinding. The main module (app), is using at this moment kotlin synthetic.

Originally I have this 2 custom views:

(Pre - ViewBinding --> This is working. I can see it in the fragment attached)

CustomView 1:

I have implemented Junit test with Mokito for my app. I like to test the Login Activity. But getting Nullpointer exception.

I want to customize a MultiAutoCompleteTextView, which will be placed inside a TextInputLayout in order to use Material, for the sake of reusability and updatability to the underlying code.

I have yet to start and I already have problems with it though.

Graphic demostration of the problem

As you can see, the first TextInputLayout is completely wrong. They both have the exact same structure and attributes, the only different thing is the custom view. It is basically an empty class that extends MultiAutoCompleteTextView.

Below is the xml and the custom view class.

I was wondering if someone found some clever solution to reuse components (multiple views) when working with MVVM.

By component I mean a set of views that end up being reused in an app. For instance, an empty state formed of an ImageView and a TextView, and let's also add some sort of ClickListener for the text, for the sake of the example.

Now, what I want to do is to reuse this view in multiple .xml files BUT providing different values for the text, the image, and bind the listener to action in the Fragment's ViewModel.

What I've been doing is create a CustomEmptyState that would extend a LinearLayout or some kind of Layout and add Custom Attributes to it.

So, in the end, I would use my custom view like this:
