Cant get all value from Firebase in Android Studio

Question

I have some problem about reading value in Firebase Database, This is structure of Realtime Database, sorry I wasn't allowed to embedded picture:

• LampController
  • Schedule
    • TimeEnd: "5:30"
    • TimeStart: "21:15"
    • isActive: true

This is my Object class, also contains Constructor, Getter and Setter:

public class ScheduleObject {
    private String TimeEnd;
    private String TimeStart;
    private Boolean isActive;

    ...
}

When I use dataSnapshot.getValue(ScheduleObject.class), I will get values from TimeEnd and TimeStart but isActive is always return null. Seem like it didn't get the value on Firebase but I don't know why?

        public void onDataChange(DataSnapshot dataSnapshot) {
            if (dataSnapshot.exists()) {
                scheduleObject = new ScheduleObject();
                scheduleObject = dataSnapshot.getValue(ScheduleObject.class);
            }
        }

Only when I use dataSnapshot.child("isActive").getValue(Boolean.class) its will return value from Firebase. Thanks for any help!

Answer 1

option 1) if your boolean field is named as isActive, then the getter must be named as isIsActive() or getIsActive()

option 2) if you want a getter isActive, the field name would be active only
