fragments | Relax Fragments API for React components and GraphQL queries | GraphQL library

Based on official documentation when we use ViewBinding in fragments, we should set binding to null in onDestroyView of the fragment:

I'm new to android studio and i'm not sure what was going on with it. How can I solve this error?

In the logcat, it mentioned that I required a view for recycler_food_list which apparently I had already coded into the foodlistfragment.java.

Logcat

I have an application under construction using the Navigation Drawer Activity which is the one with the left menu like the old version of Google PlayStore:

As you know the design comes bundled with a FAB (FloatingActionButton):

Now, in the left side menu you see these three Fragments:

I wanted to know, how do I assign different actions to the FAB when I change the Fragment? From the MainActivity I see that there is the k but I do not understand how to assign a different functionality to it, since when changing the Fragment, the same FAB is still there and executes the same action that in this case is a Toast:

I want to use navigation bottom menu with using navHostFragment in main activity. But when I run the program ,it stops on setContent in onCreat method MainActivity java code. I try to use bindig class insted setContent directly but nothing changes.

this is MainActivity.java

I have a List which contains the XML events created as a part of the output from the JAXB Marshaling approach. After completion of the JAXB Marshaling process this List can contain large amounts of XML.

These XML fragments so are part of a large XML. The large XML has some additional header elements so I am trying to create the large XML using the XMLEventWriter and trying to add the elements from my LIST but it does not work as expected and running into various errors.

I get the following error:

I am using ViewPager2 with FragmentStateAdapter to create a collection of fragments. I want to access a particular fragment on the basis of its position in the Adapter. How can I achieve the same?

I am developing a Master-Detail App.

I have 1 EntityType for Master View (Master) and another EntityType for Detail (Detail). I have created an Association from Master to Detail.

Master View works perfectly. Detail has 2 parts:

1. Header: which shows a few fields from the Line selected in Master view. (Name, ID and not much more)
2. Body: it has 2 fragments. These 2 fragments displays the info from Detail Entity.

My Issue is:

• I got errors in the Console cause fields loaded on Fragments are searched from the Entity type Master. It means that the View && Fragments are loaded before the second Binding is done.

What I have tried:

• I used the BusyIndicator and controlling the events (attachRequestComplete and/or attachEventOnce("dataReceived")) from the Model in the onInit() assigning view.setBusy(false) when they are reached. It doesn't work for me.

• I tried it out but when the Event of the 2nd binding is reached the view is already loaded.

After loading the info in Master View:

I want to change firestore query parameter when clicking button. For example, my query is this by default:

After adding the setFragmentResultListener which i use to add data that i get from another fragment to a table , i get the folllowing logcat error:
