mBus is a lightweight messaging system providing communication between daemons and applications. enabling development of component based distributed applications. every daemon registers with a unique namespace and a set of procedures with various number of arguments under the namespace. procedure request and responce are in JSON format. any daemon can post an event under registered namespace with various number of arguments in JSON format. any daemon or application can subscribe to events with namespaces and can call procedures from other namespaces. mBus consists of two parts; a server and client[s]. server interface for other daemons/applications to register themselves, send events and call procedures from other daemons/applications. all messaging is in JSON format, and communication is based on TLV (type-length-value) messages. mBus framework has built in applications; broker, subscribe, command and publish. broker is a very simple implementation of server and is the hearth of mBus. subscribe is to listen every messages generated by either server or clients, and useful for debug purposes. publish is for publishing an event, and command is for calling a procedure from connected clients. mBus client library (libmbus-client) is to simplify development of software using mbus (connecting to it).

How to save scroll state of a Recyclerview when an item is clicked?

I have an issue with Recyclerview item selection , which is set up in a fragment , the problem is each page which is created by ViewVager has its own instance of the Recyclerview so the output is that selecting Recyclerview items will reset the scroll state of the Recyclerview, so I'm looking for a solution to to save scroll state of a Recyclerview when an item is clicked.

You can solve this by tracking the current scroll value of the RecyclerView, and whenever you hit an a ReyclerView item; add a new parameter to the listener callback with this tracked scroll value to update the new fragment that will be shown on the ViewPager.

QUESTION

Can the RecyclerView scroll with the rest of the fragment layouts?

Asked 2021-Jul-05 at 12:37

I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.

The RecyclerView and ViewPager are both set inside viewpager_with_toolbar_overlay.xml Layout , and both has been settup in The Activity.

TvShowEpisodeDetailsFragment is the fragment class which belongs to activity class TvShowEpisodeDetails , the fragment creates as many episodes as a TV Show season can offer.

And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get non-fixable highlighting and scrolling issues , that is why I set it inside the activity because it does not give those issues.

I need to make it work somehow inside the activity.

My goal is that RecyclerView and ViewPager has to be in the same layout XML file and they both must either be in the activity or fragment class

Is it possible to make the RecyclerView scroll with rest of the fragment layouts?

Is it possible to do it programmatically?

Here is the activity

I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.

It's hard to use the RecyclerView outside of the ViewPager page fragment; because you can't synchronize and link the touch/motion events when you scroll the page up/down (or when you swipe to next/previous page) between both the page fragment and a standalone (i.e. activity) RecyclerView. Even that won't be smooth.

So, the RecyclerView should be a part of the ViewPager page.

And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get unfixable highlighting and scrolling issues

So, now the issue of adding the RecyclerView in the ViewPager fragment is the highlighting issue of the RecyclerView item when you click on any item or when you swipe the ViewPager to right/left page.

But, the main issue is that there is a RecyclerView instance per page, i.e. if you have 5 pages, then you have 5 RecyclerViews.

So, it's a cumbersome to track highlighting only within the RecyclerView adapter class. And hence manipulating that with OnClickListeners solely will have issues of linking these RecyclerView and adapter instances together to update their highlighting item.

So, a simpler approach is to pass a parameter to the RecyclerView adapter with the selected item (which is definitely equals to the current ViewPager page position).

And then do a check in the onBindViewHolder() if the position equals to the passed-in value, then highlight the item; otherwise keep items with the original color.

So, wrapping this up into actions:

Change the adapter constructor to accept a highlighted_position parameter

Yes, a Viewpager can be setup in a Fragment.

You just need to get the right FragmentManager when constructing it i.e use getChildFragmentManager() in mViewPager.setAdapter(new TvShowEpisodeDetailsAdapter(getSupportFragmentManager()));

From https://developer.android.com/guide/fragments/fragmentmanager

Access the FragmentManager

Accessing in an activity

Every FragmentActivity and subclasses thereof, such as AppCompatActivity, have access to the FragmentManager through the getSupportFragmentManager() method.

Accessing in a Fragment

Fragments are also capable of hosting one or more child fragments. Inside a fragment, you can get a reference to the FragmentManager that manages the fragment's children through getChildFragmentManager().

QUESTION

RecyclerView has an instance for each item of a list

Asked 2021-Jun-21 at 20:11

I have a fragment which shows a list of tv show episodes , swiping left or right will switch to the next or previous episode(this is done by ViewPager), then I created a horizontal RecyclerView to show the list of the episodes in a horizontal scroll bar.

Now I have 2 problems

Problem 1 For example I selected episode 9, now episode 9 is highlighted in the RecyclerView Scroll bar then I scroll until I reach 14, 15, 17 (this is the last scroll state of 9) then I click on 14 it gets highlighted but the scroll resets to 1 (which is not what I want) , now I scroll back and I see 14 is highlighted , now when I scroll back to 9 and tap on it , the scroll state of 9 goes to the last state that I scrolled to 15 and clicked on it. Please check this video

Problem 2 For example I selected 2 now I tap on 3, it switches to 3 but the highlight is still on 2 I have to click again on 3 to get it highlighted. please take a look at this video

I think this is all caused by the fact that each episode or I should say each page of ViewPager has its own instance of the RecyclerView. correct me if I'm wrong

But what I want is a single instance of RecyclerView to be available for all episodes.

How can I Fix that?

Hint RecyclerView Adapter is set inside the fragment, transfering the index of the clicked item (episode) from the adapter to the fragment via onItemClick interface from the adapter. From inside the fragment I use another interface sendText(int position); to tranfer the index of the clicked item to the Activity so that I can set ViewPager mViewPager.setCurrentItem(position,false);

You have just saved the position of the selected item but not the state of all the items in the list i.e whether they are selected or unselected. Recycler View recycles the views when scrolled. So, you just need to use ArrayList of PlanelModel instead of ArrayList of String as shared below which has a variable called "isPlanetSelected" to save state of the item.
