I have a Fragment that is created through a FragmentStateAdapter. The Fragment creates a view on Android Studio. I was wondering if there is a way to updates contents of the view that is generated dynamically? Say I receive some data from a server and want to add a new TextView to that view.
Couldn't find a solution :(

I am using Firebase in my project, and want to retrieve the data from the database and show it in my Text View in my profile fragment which is a part of Bottom Navigation View. I tried the bundle but it throws error for some reason. So i wanted to know is there any easy way to transfer data from main activity to fragment, specifically one row of Firebase data in different element of the fragment.
Make an interface between the the main activity and the fragment when use click to show the fragment ,fire the interface and pass the sting or what you need
another solution you can use a viewModel between the activity and fragment and fire Live data between them
you can also use EventBus

I would like to create an app in Android Studio that has a Button in Main Activity and when i clicks this button, it should open a google map with my customized lat,lng markers and camera functions as an another activity. I tried this one by creating a Button in the Main Activity.XML and wrote buttonOnClickListener() by specifying Intent that MainActivity.this,Mapfragment.class.For this I selected GoogleMaps as my start Activity instead of blank activity at starting of my project. And also for this MapFragment, I got Google maps API key. But when I run this App on my android mobile, it simply opening google map with my customized lat,lng instead of showing my Main Activity which is having a Button in it. I am confused with this, can anyone help me out of this problem.Thank You
Yes, I got it. I tried to solve this problem and got a solution for it. Initially as I said, at the starting of my project I selected a google map activity instead of blank activity. So now, to get a Button in my Main activity, I have created a MainActivity.XML in Layout folder and added a Button to it. Then, for this MainActivity.XML file corresponding .Java class was created and specified the MainActivity.XML in it and declared the Button and wrote OnClickListener for Button, so that when the Button clicks it should open my google map fragment with customized location. Importantly, we should specify this mainactivity.java in the Manifest.XML as an Activity specifying it as a Launcher activity in the Application. Now, run the app and first it displays MainActivity with a Button and now when I clicks it, it opens my google map fragment activity with the help of Intent.
I have a Fragment A with a RecyclerView.
Fragment A populates the RecyclerView items (a list of users) from SQLite and displays it in the onCreateView() method, and it works fine.
When i go to Fragment B and add a new user and hit done, i go back to Fragment A, now i should "Refresh" the users list.
I tried achieving that through moving the code from onCreateView() to onResume(). But, i have no access to a view like i do on the onCreateView().
What do you think is the best approach on handling this?
Thanks!
So, at first I suppose you should update data on your list, which one you give to your adapter. If that won't help, try to create new adapter and bind it with recyclerview in your onResume() method.
I'm developing an app which has a ListView on a Fragment, I'm getting some data from SQLite using AsyncTask and filling a ListView, but every time i switch between the tabs, the ListView is populated all over again, it's not getting all the data again, but it is putting on the List again...
Is there a way to stop that? I want that my ListView is populated only once when i create the fragment. i am using Android ActionbarSherlock Nested Fragment Tabs.
You have to detach fragment an then attach again once you return to that tab, instead of remove fragment and create again.
