android-data-binding | Sample use of Data Binding Library | Data Visualization library

I'm learning to make an android application with MVVM, I found a problem that is the data from the API generates null values. I followed the tutorial from this link, but the data samples I take are different. the data I retrieve is an object and not an array I took the data from link

Model

Moving from MVP to MVVM and trying to learn from tutorials on web.

Some of the tutorials state that ViewModel classes should not have any reference to Activity or View(android.view.View) classes.

But in some of the tutorials i've seen Views are used in ViewModel class and Activities to start other Activities using ViewModel. For example:

My problem is that I need to access my LayoutNameBinding, but I am unable to do so. Only DataBinding generated class which is available is LayoutNameBindingImpl.

• Build is successful (No errors)
• DataBinding is enabled within build.gradle(:app)
• DataBinding plugin kotlin-apt is applied within build.gradle(:app)
• My layout is contained within a
• LobbyFragmentBinding.java is generated and contains LobbyFragmentBinding

The commented part is what I would like to be able to do within my code. Part of the code shown is inspired of https://github.com/android/sunflower which explains how to use different parts of Android JetPack.

• Rebuild
• Manually add "import com.kotlin.projet3.databinding.LobbyFragmentBinding"
• Solutions found at android: data binding error: cannot find symbol class (Problem is not the same, but tried anyways)
• Solutions found at Data Binding class not generated (Problem is not the same, but tried anyways)

I'm a newbie for android data binding. I want to bind multiple SeekBars to a collection of float, such as

I have the same problem as here, but I don’t have enough reputation to ask the author if he could solve it. Can anyone know how to fix this? Android Studio does not see included layout elements. I tried clean project, rebuild project - no helps.

First, I need to acknowledge the clearly very similar but not duplicate issue here. None of the proposed solutions in that thread work.

My application file structure is as follows:

Basically I am implementing a paint app, so I made a custom View to handle event and draw on canvas. Now I would like to display the coordinate of the points being drawn on a TextView in real time. So I am trying to use a ViewModel with LiveData to do the updating. But I can't figure out a way to give the information from my custom View to the ViewModel. How would you do that ? I also tried to use BindingAdapter but I can't find a way to do that.

Here the code for my custom View:

I am using Android Databinding adapter and it says, it have to be static. So I am trying to make it non static and inject my classes into it with Dagger by following this tutorial. Although I can use my Picasso instance which is provided by dagger normally in app, it says Picasso cannot be provided without an @Inject constructor or an @Provides-annotated method.

I add @Inject annotation to my binding adapter constructor but still get same error
