fragment showing but recycler view isn't

The button view shows confirming that the fragment shows, however the recycler view doesn't.
The logged array size of "jobs" is 1, confirming that getItemCount() isn't the problem and that the recycler adapter constructor is called. I'm reusing my JobRecyclerAdapter class but nothing's static, so there shouldn't be any interference between the two instances. The layout is a a copy of a working one I have, minus different ids and layout name, so that shouldn't be a problem either. There are no errors.

Fragment (I only showed the relevant parts of the fragment.)
RecyclerView jobRecyclerView;
JobRecyclerAdapter jobRecyclerAdapter;
LinearLayoutManager llm;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.sub_fragment_active_jobs_1, container, false);
this.jobRecyclerView = view.findViewById(R.id.activeJobRecyclerView);
return view;
}
public void configureJobsRecyclerAdapter(Job activeJob, List<Drawable> imageDrawables) {
Log.d("downloadActiveJob", "configureJobRecyclerAdapter called");
List<Job> downloadedJobs = new ArrayList<>();
downloadedJobs.add(activeJob);
Integer arraySize = imageDrawables.size();
Log.d("downloadActiveJob", "configureJobRecyclerAdapter: " + arraySize.toString());
jobRecyclerAdapter = new JobRecyclerAdapter(downloadedJobs, imageDrawables, this);
llm = new LinearLayoutManager(context);
jobRecyclerView.setLayoutManager(llm);
jobRecyclerView.setAdapter(jobRecyclerAdapter);
}
Update: If I move the recycler view/adapter setup code to onResume, the recycler view is visible. When I update the recycler view with a new adapter, the recycler view becomes invisible.
If I can't solve it using this new discovery I'll post the whole fragment.

Hey, you create the function configureJobsRecyclerAdapter() but didn't call it inside fragment onCreateView(). Like...
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.sub_fragment_active_jobs_1, container, false);
this.jobRecyclerView = view.findViewById(R.id.activeJobRecyclerView);
configureJobsRecyclerAdapter()//Add this line.
return view;
}

if you are fetching data which are required for configureJobsRecyclerAdapter() from an api maybe you are setting empty list at the time when you are calling configureJobsRecyclerAdapter(). and that's why when you call it in onResume, the list becomes visible(because then data is fetched).
and don't forget to call adapter.notifyDataSetChanged() after each change in your list.

Android Spinner Inside RecyclerView Get Current View When Selected

I have a RecyclerView implementing a LinearLayout of CardViews through an adapter. Inside each CardView, I have a spinner. What I need to do is get the CardViews position when a spinner is selected. Ex.. if I have 10 CardViews in a list on the screen with a spinner in each, and a select a value from the spinner in the 5th item, I need to get that 5th position as well as the selected value.
I'm able to get the selected value just fine. The issue is with getting the CardViews position. The CardViews are being generated from an ArrayList.
I will include my code below along with an image of the desired results. Any help is greatly appreciated!!

You can set an OnClickListener on mGameSpinner in your onBindViewHolder().
onBindViewHolder(final PopularAdapter.MyViewHolder holder, final int position)
You can then store/use the position parameter as it will be the index into your gameArray for that particular spinner. You can then use that index to grab the spinner's currently selected value and do whatever you need to do with it.

I think you should set a tag for each view in the RV through the holder in onBindViewHolder. Something like:
holder.itemView.setTag(game.getId());
The game's Id should be one of the data points in the ArrayList you passed into the Adpater. So it'd be easier to add a getId() method to your game object.
Once you have an integer Id to call on that's unique to each game in the list, you can simply find that Id within the Spinner's onItemSelectedListener with:
int ID = (int) holder.itemView.getTag();
Then you can use ID within your if-else statements to know which game within your card list the spinner is selected for.

#Override
public void onBindViewHolder(final LanguagesAdapter.MyViewHolder holder, final int position) {
holder.edit_language_name.setText(edit_languageDetails_ArrayList.get(position).getEt_language_name());
sp_langage_rating=edit_languageDetails_ArrayList.get(position).getEt_language_ratings();
String ss=sp_langage_rating;

RecyclerView not displaying items, no errors being reported

So here is the gist of the issue, I have implemented RecyclerViews in several activities successfully, however this particular RecyclerView DOES NOT DISPLAY ANYTHING!
I have created a fragment within a tablayout to display, and also rewritten the code thrice. Here is the code for the entire fragment(View is inflating fine, along with a searchbar on top of the recycler) adapter is at the bottom. I have left OnBindViewHolder blank on purpose as I wrote it twice before aldready without any results. Any help would be appreciated.

PS: I have checked the dataset which is returning a size on querying the database, the adapter has been notified too and the getItemCount returns a non-zero size. I am honestly clueless as to what the problem is!
EDIT: Here is the (almost) identical code i used for another static inner class fragment. This implementation works just fine.

}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

case R.id.bApplyJob:
serverRequests.applyForJob(receivedUser.getEmail(), receivedUser.getName(), jobID.getText().toString(), jobPos.getText().toString());

}
}
}

Your ViewHolder must work with views for display. Example:
public VH(View v) {
super(v);
jobLocation = (TextView) v.findViewById(R.id.returnedJobLocation);
jobLocation.setText("something location");
}

RecyclerView not populating on fragment

I have been trying to figure this problem out for quite a while now, but i just can't figure out what the problem is. The aim is to make a request to Songkick api (which is json), which will return the upcoming events of artist and populate it on the the fragment. The request works fine, but it doesn't come on the screen using recyclerView.
This is my xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

android:id="#+id/List"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
This is the Adapter:
public class AdapterEvents extends RecyclerView.Adapter<AdapterEvents.ViewHolderEvents> {
private LayoutInflater layoutInflater;
private String cls = "TAG";
private ArrayList<Events> listEvents = new ArrayList<>();
public AdapterEvents(Context context){
layoutInflater = LayoutInflater.from(context);
}
public void setListEvents(ArrayList<Events> listEvents){
this.listEvents = listEvents;
notifyItemRangeChanged(0,listEvents.size());
}
#Override
public ViewHolderEvents onCreateViewHolder(ViewGroup parent, int viewType) {
View view = layoutInflater.inflate(R.layout.custom_events,parent,false);
ViewHolderEvents viewHolder =new ViewHolderEvents(view);
return viewHolder;
}
//create an object for each textview
#Override
public void onBindViewHolder(ViewHolderEvents holder, int position) {
Events currentEvent = listEvents.get(position);
holder.DateTextView.setText(currentEvent.getStartDate());
// + "--"+ currentEvent.getEndDate()
holder.displayName.setText(currentEvent.getDisplayName());
holder.Venue.setText(currentEvent.getVenue());
}
#Override
public int getItemCount() {
return listEvents.size();
}
static class ViewHolderEvents extends RecyclerView.ViewHolder{
private TextView DateTextView;
private TextView displayName;
private TextView Venue;
public ViewHolderEvents(View itemView){
super(itemView);
DateTextView = (TextView) itemView.findViewById(R.id.DateTextView);
displayName = (TextView) itemView.findViewById(R.id.displayName);
Venue = (TextView) itemView.findViewById(R.id.Venue);
}
}
}
and this part is from my fragment class:
public void sendRequest(){
// Formulate the request and handle the response.
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET,
getRequestUrl(),(String)null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse( JSONObject response) {
listEvents= parseJSONResponse(response);
adapterEvents.setListEvents(listEvents);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// Handle error
}
});
requestQueue.add(request);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_events, container,false);
recyclerView = (RecyclerView)view.findViewById(R.id.List);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
adapterEvents = new AdapterEvents(getActivity());
recyclerView.setAdapter(adapterEvents);
return view;
}
I have been on this for about a few days, and it's sort of frustrating because it's my project that is due in a week time. Any sort of help will be much appreciated. Thanks in advance.

How to implement OnSetClickListener for button in RecyclerView?

I have been having difficulties making my device register button clicks within an android recyclerview and am not sure why it is not responding as I have looked around and it seems as though it should work. But what I really want to know is if I have put stuff in the wrong place, am I missing something and if so what?
Holder Class
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView time;
public ImageButton button;
public ViewHolder(View v) {
super(v);
time = (TextView)v.findViewById(R.id.time);
button = (ImageButton)v.findViewById(R.id.imageButton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("Test", "Button clicked");
}
});
}
}
Adapter Class
public class ListAdapter extends RecyclerView.Adapter<ViewHolder> {
// WIll hold the timer objects passed through
ArrayList<Timer> lData = null;
// Provide a suitable constructor (depends on the kind of dataset)
public ListAdapter(ArrayList<Timer> myDataset) {
lData = myDataset;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_adapter, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.time.setText(lData.get(position).getTime());
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return lData.size();
}
// Gets the timers
public ArrayList<Timer> getData() {
return lData;
}
}
Main Activity Class (OnCreate Method)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new ListAdapter(timers);
mRecyclerView.setAdapter(mAdapter);
}
