QUESTION
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:

QUESTION
I'm having an issue that maybe is happening to other community members and I wanted to ask if somebody knows the solution. I have an app with these Two activities (MainActivity, UserProfileActivity).
The MainActivity contains a NavigationDrawer that navigates through fragments. So here it's the problem. While navigating in the second fragment and pressing a button in that fragment. It opens the UserProfileActivity (child of MainActivity) with the app bar generated by being a child. When you press that back button of this new Activity it should get back to MainActivity (parent) in the fragment that we were when we called this new Activity. But not, it's getting back to the MainActivity but with the home fragment loaded. Not the one we called previously.
Does anybody know how to solve that problem? Here I leave the code of the intent I do from the fragment:
...ANSWER
Answered 2021-Jun-09 at 13:55Reason behind this behavior:
If you set the value of android:parentActivityName
in your manifest.xml, by default pressing navigation button will create a new instance of the parent activity every time rather than popping it out from the activity backstack, so you're seeing the home fragment.
Workaround
At first, remove android:parentActivityName
from manifest.xml. In onCreate method of your ChildActivity, put getSupportActionBar().setDisplayHomeAsUpEnabled(true)
if you haven't already. Then override onSupportNavigateUp()
of your ChildActivity, and put finish()
.
ChildActivity.java:

ANSWER
Answered 2021-Jun-05 at 12:05There are two things I would like to suggest here.
- First if possible get back to
ConstraintLayout
as in your last answer. It is not necessary for sure, but would recommend. - Second the blipping might be cause by the difference in
elevation
since theelevation
ofNavigationView
is different.
So I suggest you add the following to your FragmentContainerView

QUESTION
I am currently developing an Android NFC application. This application contains a NavigationDrawer in which I can access 3 different fragments which each correspond to 3 different NFC features.
My goal is that when the onNewIntent method is called, so when the NFC tag is detected, I update the UI with the information in the tag.
At first, the update of the UI is done synchronously but the idea is to have something asynchronous by using coroutines in the future.
The problem is simply that the UI does not update when the onNewIntent function is called, can you help me?

Answered 2021-May-05 at 13:17Your problem is that ViewModelProviders
returns different viewModel
instances, and when you try to assign some _icManufacturer
value, it changes in the activity's ViewModel, but not in the fragment's ViewModel.
You should add the following code

I created NavigationDrawer for my HomeScreen and now want to add it in every Activity. How can I do this without copy/pasting code into every Activity? Below is my HomeScreen XML code.
...ANSWER
Answered 2021-May-04 at 04:24Normally, IMHO, NavigationDrawer is intended to use with Fragment. A main Activity has its NavigationDrawer that is common among Fragments. So that each Fragment doesn't have to have or manage its own NavigationDrawer.
In Activity:
