fragment | Simple fragment/substring matching library

I'm using create-react-app and have configured my project for eslint. Below is my .eslintrc file.

I'm doing a Group Chat with Firebase and currently I'm using a RecyclerView to display chat messages and I'm having a problem. When you open the app in the fragmented home and you go to chat activity and start chatting (adding elements to recycler view) all goes fine. But, when you go via the NavigationDrawer to another fragment and get back to the chat fragment using again this Navigation Drawer. When you add one element in the chat it appears all in the blank it just displays the last message. Anybody knows why does this happens?

Here I leave the RecyclerView Adapter Code:

I have an Activity. In the Activity, I have a Navigation Drawer on the Left and a fragment. In the Navigation Drawer, I have a textview for Name. I want to set the text view from Fragment to Navigation Drawer in activity

Here's the image:

Here the Code in Activity(MyActivity.java):

I'm creating 2 pages (Summary and Cycles pages) using react.js.

On the Summary page, there is a column named CN that every item links to the Cycles page.

Summary page has a path /route/summary/location=abc and Cycles page has a path /route/cycle/location=abc/deviceId=4410

For example, if I click the value from CN column in the first row of the table inside the Summary page, I will be redirected to the Cycles page with the path /route/cycle/location=abc/deviceId=4410.

In the Summary page, I use https://github.com/react-bootstrap-table/react-bootstrap-table2 for the table component and I use a columnRenderer function inside columns.js to render a custom item inside the table like this one:

How can I put the pathname (example "abc") to a Link component inside cnColumnRenderer function in columns.js?

Summary page with the path: /route/summary/location=abc

Cycles page with the path: /route/cycle/location=abc/deviceId=4410

Error because of invalid hook call while rendering the Summary page

table code inside Summary page (inside Summary.js):

hint: focus on columns variable from './columns' and its implementation

From an API request, I get an array of data like below (I get 100 elements, but here I'm showing only 2):

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.

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:
