How can I check if an individual toggleButton in my recyclerView is selected?

Question

I am creating an app that allows the user to create alarms and if the alarm is toggled on, then it will use broadcast receiver to wake the user up. The issue I am currently having is checking if a toggleButton from the recyclerView is checked. I need to check if each one is on and if it is, wake the user up at the set time. Any help is greatly appreciated!

Activity that allows user to create the alarm object

import com.google.android.material.floatingactionbutton.FloatingActionButton;

import java.util.Calendar;

public class CreateAlarmObject extends AppCompatActivity {

    FloatingActionButton backButton;
    Button addButton;
    EditText name, time;
    Item newItem = new Item(R.drawable.ic_clock, "Line 1", "Line 2", false, 0, 0);
    int currentHour, currentMinute;

                currentHour = alarmTimePicker.getCurrentHour();
                currentMinute = alarmTimePicker.getChildCount();

                    Log.d("Item added", (i + 1) + ": " + newItem.getName(i) + ", " + newItem.getTime(i));
                }

            }
        });
    }
}

And the item class itself

        }

        @Override

            return new Item[size];
        }
    };

    public int getImageResource () {
        return mImageResource;
    }

    public String getText1 () {
        return mText1;
    }

    public String getText2 () {
        return mText2;
    }

    public void setText1 (String newString) {
        mText1 = newString;
    }

    public void setText2 (String newString) {
        mText2 = newString;
    }

    public void addActivity (int time, String name) {

        myActivities.add(newActivity);
    }

    public int numActivities () {

    }

    public int getTime (int i) {

    }

    public String getName (int i) {
        return myActivities.get(i).getName();
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(mImageResource);
        dest.writeString(mText1);
        dest.writeString(mText2);
    }

    public boolean getToggleOn(){ return toggleOn; }

    public void setToggleOn(boolean toggleOn) { this.toggleOn = toggleOn; }

    public int getCurrentHour () {
        return currentHour;
    }

    public int getCurrentMinute () {
        return currentMinute;
    }

    void setCurrentHour (int newHour) {
        currentHour = newHour;
    }

    void setCurrentMinute (int newMinute) {
        currentMinute = newMinute;
    }
}

Answer 1

if I get you Right I think you can do it this way
1 Disable the Recyclable by this.setIsRecyclable(false) this line of code in the constructor of the viewholder class
only if you have limited items in your list
2. Add The toggle event on the Toggle Button

    mToggleButton = itemView.findViewById(R.id.toggleButton);
    mToggleButton.setOnCheckedChangeListener(
    new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
        {
          currentItem.setToggleOn(isChecked);
            
        }
      }
    });

Also effect the changes to the source eg database.
3. check the toggle property of your current item in the onBindViewHolder method like

       if (currentItem.getToggleOn())
          holder.mToggleButton.setChecked(true);
        
       else
           holder.mToggleButton.setChecked(false);
        }
