QUESTION
So, I have an activity which contains three fragments and I am switching between the fragments using ViewPager.
So in one of my Fragment I am using a recycler view to load my data. I am using onCreateView to initialize my view and populate recycler view also. But the problem here is when I switch back and forth between the fragments my recycler view items gets loaded again. I don't want that. I want the items to be loaded only once.
eg. when I switch back and forth between IMAGES and SAVED tab the recycler view gets reloaded in IMAGES tab.(ps. look at image to understand better)
This is my fragment where recycler view is loaded.

QUESTION
The title itself is my problem, whenever I open MainActivity then navigate to another fragment available in the hamburger/drawer menu then press/swipe back to return in main screen (first fragment) it recreates. Is there away for Nav Component to make it not recreate the first fragment? I am using the Jetpack Navigation template generated by Android Studio and it seems that is the default behavior.
This is the MainActivity
...ANSWER
Answered 2021-Apr-23 at 04:30As per the Saving state with fragments guide, it is expected that your Fragment's view (but not the fragment itself) is destroyed and recreated when it is on the back stack.
As per that guide, one of the types of state is non config state:
NonConfig: data pulled from an external source, such as a server or local repository, or user-created data that is sent to a server once committed.
NonConfig data should be placed outside of your fragment, such as in a ViewModel. The ViewModel class inherently allows data to survive configuration changes, such as screen rotations, and remains in memory when the fragment is placed on the back stack.
So your fragment should never be calling fetchAssets("30") in onCreateView(). Instead, this logic should happen inside a ViewModel such that it is instantly available when the fragment returns from the back stack. As per the ViewModel guide, your fetchAssets should be done inside the ViewModel and your Fragment would observe that data.
QUESTION
After performing filtering on Recyclerview items that are fetched through json. It's opening the wrong item when I clicked after filtering the list. Suppose A,B,C,D are in my list, and when I filter for B and click on it - it shows the wrong item (like: A,C,D) but not B. How to fix this?
MainActivity.java:

I have a problem, when i swipe to refresh the data, the first swipe is ok but after that every swipe reload and add the same data over and over again, by the end i have a list with same items over and over... I'm using a loader. I tried to clear before but i don't understand what's wrong with my code, if someone could explain it to me. Thank You. Here my code :
...ANSWER
Answered 2020-Aug-06 at 13:13Just use mExampleList.clear() at the first line of your parseJSON() function and then you'll be able to add the "updated" items.
In addition I'd suggest that you move swipeRefreshLayout.setRefreshing(false) to the end of Volley onResponse and onError() implementation - Right now you're telling the swipeRefreshLayout to stop refreshing before the request(that happens asynchronously) has finished

QUESTION
I've created a simple project to study Kotlin and Android architecture
https://github.com/AOreshin/shtatus
The screen consists of RecyclerView and three EditTexts.
Corresponding ViewModel is exposing 7 LiveData's:
- Three LiveData corresponding to filters
- Event to notify the user that no entries are found
- Event to notify the user that no entries are present
- Status of SwipeRefreshLayout
- List of connections to show based on filter input
When user types text in filter ViewModel's LiveData gets notified about the changes and updates the data. I 've read that it's a bad practice to expose MutableLiveData to Activities/Fragments but they have to notify ViewModel about the changes somehow. When no entries are found based on the user's input Toast is shown.
The problem
When the user enters filter values that have no matches, Toast is shown. If the user then rotates the device Toast is shown again and again.
I've read these articles:
https://proandroiddev.com/livedata-with-single-events-2395dea972a8
But I don't understand how I can apply these to my use case. I think the problem in how I perform the updates

Answered 2020-May-28 at 23:18After some head scratching I've decided to go with internal ViewModel statuses, this way logic in Activity/Fragment is kept to a minimum.
So now my ViewModel looks like this:
QUESTION
I have the following problem. Posts of other users are coming out fine only one post. But if it's your profile, in the HomeFragment the posts are coming out duplicated and I am not sure why that is.
In my readPosts(); method, if I get rid of this line } else if (mFirebaseUser.getUid().equals(post.getPublisher())) {mPostLists.add(post); it's fine, but then my posts don't show up only the posts of the people I follow. I need mine to show up also in the newsfeed, but just once not duplicated. All of my posts are being duplicated. Same post comes up twice on my feed. Can someone tell me what I am doing wrong?
Something I am doing wrong in my readPosts(); method, but I am not sure what after having played around with it a bunch.
HomeFragment
...ANSWER
Answered 2020-Apr-18 at 23:50Check your inner loop in readPosts(). The loop is based on elements of mFollowingList. This condition has nothing to do with that:
