How do i pass data to another method

i am trying to set up a delete button to delete a customer from a table, the customers are displayed in card views using a recycler view so each customer will have their own delete button, the customer information are displayed using textviews. i need to pass the customer id to the delete method i order to search the table for that specific id to delete. how do i pass the data succesfully?

this is what iver currently got to try and pass the data i need

 public void onBindViewHolder(@NonNull MyHolder holder, final int position) {

        holder.idText.setText(String.valueOf(id.get(position)));
        holder.nameText.setText(String.valueOf(name.get(position)));
        holder.surnameText.setText(String.valueOf(surname.get(position)));
        holder.add1Text.setText(String.valueOf(add1.get(position)));
        holder.add2Text.setText(String.valueOf(add2.get(position)));
        holder.add3Text.setText(String.valueOf(add3.get(position)));
        holder.postCodeText.setText(String.valueOf(postCode.get(position)));
        holder.phoneNumberText.setText(String.valueOf(phoneNumber.get(position)));
        holder.emailText.setText(String.valueOf(email.get(position)));
        
        GlobalVars.id = holder.idText.getText().toString();

        holder.delete.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                db.deleteCustomer(GlobalVars.id);
            }
        });
    }

this is my delete method

public long deleteCustomer(String id)
    {
        SQLiteDatabase db = this.getWriteableDatabase();
        ContentValues idValue = new ContentValues();
        idValue.put(CUSTOMER_ID, id);

        return db.delete(TABLE_NAME, "where Customer_ID = " + idValue, null);
    }

when i run the app it displays the customers and the buttons but when i click any of the buttons i get a blank screen then it returns to the login screen i have.

this is the errors that show up in logcat
