I can't setProgress(0) of ALL Seekbars in RecyclerView when clicking a button (Android)

I have a RecyclerView of questions (which are saved and retrieved from database) and seekbars (which I save in database).
Link to image
After clicking on SUBMIT EXTRA QUESTIONS there is a dialog which appears
Link to image
I want after clicking on Okay the progress of ALL seekbars to be 0.
I tried to do this submitExpenseData(jsonArrayQuestion.toString(), getId, jsonArrayAnswer.toString(), formatter.format(date));
holder.seekBar.setProgress(0);
But It changes only the progress of the last seekbar. Does anyone have any idea?

Repository class returning null values in ViewModel to recycler view list

Here is so far my implementation. I am trying to get the list of Bluetooth devices after the scan is finished. But the observer is not returning a list of devices.

How to Update Images and Text in Firebase and Retrieve Them In RecyclerView

I followed a Tutorial and was Successfully able to Load the data in Firebase and also retrieve it back in RecyclerView and also Learned How to Delete data but now I'm Stuck that how to update this data in the Firebase and show it in RecyclerView.I have used Picasso for the Images.
This is my Gallery.java file

Any Solution for this how can I update it.

There is no update method in firebase storage, So for a workaround:
get the name the file you want to delete
delete the file you want to update
upload the new file
rename file with the previous file name

How to sort recyclerView, Bold item if unread and unbold if item opened?

I have 2 Activities in my application.
activityMain contain 3 Fragments
The third fragment is a conversations list. This is a recylerView where each Item leads to a specific chat.
activityConversation contains a Chat.
First, i would like to sort the conversations in the the recyclerView in order of "Last actives". The most recent active should be displayed on top of the list, the second last active on second postition etc...
Secondly, each Item of the recyclerView contains a Textview. For each item, I would like to display the last message posted in the related chat in this Texview.
Finally, i would like to display these Item textViews in Bold since the conversation has not been opened until the last chat update.
Has anyone an Idea to help me achieve that?
Here my Chat Activity:

Thank you in advance for your time.

maintain a flag in data level to know is it read or unread,based on that you can apply the styles.

There is two way to do this.
First you can ask to backend to write server side to query to handle last activity bases of timestamp .In this case you have to send your particular timestamp to server when you open particular conversation .
Other you can make local database ex-(sql database) and handle it in your own code by updating query when you reading or undreading conversation.

First page of ViewPager not getting rendered

I am using a ViewPager to be able to swipe between views. The problem that I am facing is, the first page does not render properly(only the static members from layout file get rendered), but the second page and further pages are rendered properly. Also, when I go to third or later page and then come swiping back to the first page, it gets rendered perfectly.
I know that ViewPager loads the first page as well second page in the beginning and does the same for every next page. Is this the reason why my first page is not rendered properly? I am making a network call on each page and the data returned is being displayed on the page.

just add this method to your Class
#Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
it will render every time when you enter to particular layout. this is the override method of pagerAdapter.
