Participants view not showing all participants when opened while participants join and leave

[tomastiminskas]

Base branch: develop: All new changes needs to be done using develop branch as base branch. We use develop as base for Test Flight distribution releases. Pull from develop before starting any new ticket

Context

• Tapping on the 3 dots button on the top right corner of the chat view and then selecting Create Call sends a call message to a contact
• From the message row you can join the call inside Sphinx
• When inside the call the forth button from left to right will present a view from bottom with the list of participants in the call

Involved files

• CallActivity.kt
• ParticipantsFragment.kt
• fragment_participants.xml

Issue description

• When the participants view is presented and a participant joins or leaves the call, the title of the view will update with the new participants count, but the list won't so the old list will still be visible

Screenshots

1. You are on the call and the participants view shows "1 Participant" and just one item for you on the list
   

2. A second participant joins the call, the title of the participants view updates and now show "2 Participants", but the list still shows 1 item. It should update automatically and show the 2 participants in the call
   

Requirements

• Fix the participants view logic and UI so every time the participants in the call change, the view is updated even if it's visible

Acceptance Criteria

• Fix issues related with participants list not updating when participants change while view is presented

@tomastiminskas I'll take this, might take some time for me so if someone else comes along feel free to take it from me.

@seankibler any updates on this?

[seankibler]

@tomastiminskas I'm sorry I have been busy and am just finishing up another bounty. I'm ready to dive in now if it is still needed.

[tomastiminskas]

@seankibler yes of course, go ahead!

@tomastiminskas well I've made progress. I've got the list updating but it's rendering a whole new list over top of the old one. Hoping to fix that up this weekend. Hopefully PR incoming soon.

@peacejokanola I wasn't able to test your changes since when trying to run from the changes on your branch (after merging into a branch on our side) it throws a compilation error that is preventing the app to run. Basically it's not finding setOnDismissListener on CallActivity.kt. Screenshot attached:

Once you solved this I will be able to test and check if the issues is fixed and the feature is working as expected. Thanks in advance
