Bonjour je cherche a actualiser un textview dans un fragment après la suppression d'un élément d'une liste.

Mon fichier MainFragment:

import android.os.Bundle;
import androidx.fragment.app.Fragment;

import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import com.mycodeapps.todotasks.R;
import com.mycodeapps.todotasks.Utils.DatabaseManager;


public class MainFragment extends Fragment{
    private TextView taskCompleted;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView =  inflater.inflate(R.layout.fragment_main, container, false);
        taskCompleted = rootView.findViewById(R.id.tasksCompleted);
        DatabaseManager db;
        db = new DatabaseManager(getContext());
        db.openDatabase();
        upDateScore(db);
        return rootView;
    }

    public void upDateScore(DatabaseManager db){
        Log.i("DEBUG", (String) this.taskCompleted.getText());
        String pctScore = getString(R.string.done)+" "+db.readPctScore()+getString(R.string.pct);
        taskCompleted.setText(pctScore);//affectation du pourcentage
        Log.i("DEBUG", (String) this.taskCompleted.getText());
        db.close();
    }
}

Mon adapter:

import android.annotation.SuppressLint;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.mycodeapps.todotasks.Fragments.MainFragment;
import com.mycodeapps.todotasks.MainActivity;
import com.mycodeapps.todotasks.Model.taskModel;
import com.mycodeapps.todotasks.NewTaskActivity;
import com.mycodeapps.todotasks.R;
import com.mycodeapps.todotasks.Utils.DatabaseManager;
import java.util.List;

public class tasksAdapter extends  RecyclerView.Adapter<tasksAdapter.MyViewHolder>{

    private List<taskModel> tasksList;
    private final MainActivity activity;
    private final DatabaseManager db;
    private final MainFragment fragment;

    public tasksAdapter(DatabaseManager db, MainActivity activity, MainFragment fragment) {
        this.db = db;
        this.activity = activity;
        this.fragment = fragment;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
        View view = layoutInflater.inflate(R.layout.task_layout,parent,false);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        db.openDatabase();
        final taskModel item = tasksList.get(position);
        holder.task.setText(item.getTask());
        holder.task.setChecked(toBoolean(item.getStatus()));
        holder.task.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    item.setStatus(1);
                    db.updateStatus(item.getId(),1);
                } else {
                    item.setStatus(0);
                    db.updateStatus(item.getId(), 0);
                }
            }
        });
    }


    private boolean toBoolean(int n) {
        return n != 0;
    }

    @Override
    public int getItemCount() {
        return tasksList.size();
    }

    public Context getContext() {
        return activity;
    }

    @SuppressLint("NotifyDataSetChanged")
    public void setTasks(List<taskModel> tasksList) {
        this.tasksList = tasksList;
        notifyDataSetChanged();
    }

    public void deleteItem(int position) {
        taskModel item = tasksList.get(position);
        Bundle bundle = new Bundle();
        bundle.putInt("status", item.getStatus());
        bundle.putString("task", item.getTask());
        db.deleteTask(item.getId(),item.getStatus());
        tasksList.remove(position);
        notifyItemRemoved(position);
        ((MainFragment)fragment).upDateScore(db);
    }

    public void editItem(int position) {
        taskModel item = tasksList.get(position);
        Bundle bundle = new Bundle();
        bundle.putInt("id", item.getId());
        bundle.putString("task", item.getTask());
        bundle.putInt("status", item.getStatus());
        NewTaskActivity fragment = new NewTaskActivity();
        fragment.setArguments(bundle);
        fragment.show(activity.getSupportFragmentManager(), NewTaskActivity.TAG);
    }

    public static class MyViewHolder extends RecyclerView.ViewHolder {
        private final CheckBox task;
        public MyViewHolder(View view) {
            super(view);
            task = view.findViewById(R.id.todoCheckBox);
        }
    }

}

Dans mon adapter je souhaiterais quand j'exécute deleteItem mettre a jour le textview taskcompleted de mon fragment. J'ai créé une méthode dans mon fragment mais je n'arrive pas a y acceder. Je bloque si vous avez une solution je suis preneur.

Edit: Les erreurs retournées sont que les references dans la methode updatescore sont introuvables (taskcompleted, les 2 getstrings done et pct) .
