Why my recyclerview isn't showing any item?

I just created my recyclerview to show a cardview when I just filling the required data on AddNewTimerFragment.java. But somehow it wont show the card that contains the data that I've fill in before. I've tried to changes something, but doesn't work.

Calculation using JSON Data in RecyclerView and ToggleButton

I want to do calculation using JSON Data in RecyclerView with ToggleButton. When the toggle button is checked the value should change and when its not checked the value should change again for that particular RecyclerView row. The problem is when I click the ToggleButton, 2 other RecyclerView row's ToggleButton is also checked.

I would suggest to have all your item properties in one object and add the background color to it.
When a color is picked just save it to your verse object and when view is created set it.
Also add the background to your ViewHolder.
public class Verse {
private String versenumber;
private String verseid;
private String verselist;
private String refernce;
private int backgroundColor
// Getters and setters
}
public class FullverseAdopter extends ArrayAdapter<Verse> {
private ALLVERSE activity;
private List<Verse> verse;
TextToSpeech textToSpeech;
private DatabaseHelper mDBHelper;
private SQLiteDatabase mDb;
private int selectcolor;
ArrayList<String>colors;
public FullverseAdopter(ALLVERSE context, int resource, List<Verse> verse) {
super(context, resource);
this.activity = context;
this.verse = verse;
}
// The rest of your code
}

Change colour of an item view in recycler view after comparison with its textview data

I have a RecyclerView with 'n' number of ItemViews in it. These ItemViews contain Textviews with data with are updated through Firestore.
Now I need to compare one of the value0(getexpirydate) in the Textviews with another value1(Current date). Then if value1 > value0, then change the colour of that specific Itemview to RED. else GREEN.

So was able to make it work by adding this before setText.
String date = new SimpleDateFormat("dd.MM.yyyy", Locale.getDefault()).format(new Date());

Date d1 = new SimpleDateFormat("dd.MM.yyyy").parse(contract.getDateofexpiry());
if (d1.after(date1)){
holder.contractname.setTextColor(Color.GREEN);
}
} catch (ParseException e) {
e.printStackTrace();
}

#Override
public void onBindViewHolder(#NonNull ContractsAdapter.ContractViewHolder holder, int position) {
Contracts contract = contractsList.get(position);
if (contract.getCurrentDate() > contract.getDateofexpiry()) {
holder.dateofexpiry.setTextColor(Color.RED);
}
holder.dateofexpiry.setText(contract.getDateofexpiry());
}

Scrape web's infinite scrolling “load more” button using Java in Android Studio

So far I can't find an article that explains how to handle scraping infinite scrolling page in Android Studio's Java. Maybe I'm not good at searching or else.
I'm doing a news app project that will display news using web scraping technique, and can also fetch data from the next page.
More on here : How to crawl a website with multiple pages using java
But, now I'm facing a new problem because one of my news source using infinite scrolling method for their site -> https://www.gameinformer.com/news
