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?

it comes out from there and goes to failure and i am not getting the result after clicking the button.its showing me nothing .

Please help me for ViewOrder Activity

Here I am posting my code. After selecting checkbox user click on save button and onClick of that, another activity is open with only selected items(As you want),
Here is my code:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.rView);
context = this;
numberlist = new ArrayList<Number>();
for (int i = 0; i < 50; i++) {
Number number = new Number(String.valueOf(i), false);
number.setSelected(false);
numberlist.add(number);
}
customAdapter = new CustomAdapter(context, R.layout.list_item, numberlist);
recyclerView.setAdapter(customAdapter);
btn = (Button) findViewById(R.id.button1);

Android Recyclerview, okhttp, receiving an java.lang.ClassCastException error

I am trying to load data into my recyclerview via url okhttp calls, and I am receiving the following error:

It can't be cast because it doesn't implement that interface. Your commented-out #override statement should be a clue for you here.
Change it to:
public class SearchActivity extends AppCompatActivity
implements SearchForBarbershop.BarbershopRequesterResponse {
....
And don't forget to remove the comment for method you implemented:
#Override
public void receivedNewShop(final Barbershop newBarbershop) {
....

I think you need change constructor SearchForBarbershop
BarbershopRequesterResponse listener;
Context context
public SearchForBarbershop (Context context,BarbershopRequesterResponse listener) {
client = new OkHttpClient();
isLoadingData = false;
this.context = context;
this.listener = listener;
}
And change in SearchActivity
searchForBarbershop = new SearchForBarbershop(SearchActivity.this, this);
