How Can I Update My Information In Different Location? Android Firebase

Click this to see Firebase Data Structure I want to update my information (firstname, middlename, lastname) which is in a different location. I'm updating my information using stud

Solution 1:

To update a record in a Firebase database, you can use setValue() method directly on the reference. Assuming that teacher is the direct child of the Firebase root, you can use this code:

DatabaseReferencerootRef= FirebaseDatabase.getInstance().getReference();
DatabaseReferencefirstNameRef= rootRef.child("teacher").child(teacherId).child("class").child(classId).child("Listofstudents").child(listId).child("firstname");
firstNameRef.setValue("New Name");

In which teacherId, classId and listId are those random generated keys that i see in your database.

If you want to update the same data, in a different location, just add another reference to desired location and use the same setValue() method.

Hope it helps.
