Set value from Firebase Realtime Database to RadioButton

Question

Is there a way I can set a RadioButton with a string value in my Firebase Realtime Database? Is it possible? Below is my code.

DatabaseReference questions_beg_java = FirebaseDatabase.getInstance().getReference().child("Questions").child("BeginnerJava").child("QuestionOne");
        questions_beg_java.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

                String question_one = dataSnapshot.child("question_one").getValue().toString();
                String answer_one = dataSnapshot.child("answer_one").getValue().toString();
                String answer_two = dataSnapshot.child("answer_two").getValue().toString();
                String answer_three = dataSnapshot.child("answer_three").getValue().toString();

                //radioButton1.
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });

What do I add to set a value to the RadioButton? As in retrieving it from Firebase Realtime Database?

How do you want to set the RadioButton? Which value from the database should be used? Could you use a [switch statement](https://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html)? — Grimthorr, Nov 15 '18 at 15:03

The Android [`RadioButton`](https://developer.android.com/reference/android/widget/RadioButton) view inherits from [`TextView`](https://developer.android.com/reference/android/widget/TextView), so you can use [`setText()`](https://developer.android.com/reference/android/widget/TextView#setText(java.lang.CharSequence)). — Grimthorr, Nov 15 '18 at 15:22

The Android RadioButton widget is basically a TextView with some extra styling and functionality. It is therefore inheriting all methods from TextView, including setText().

This means that you can do something like:

String answer_one = dataSnapshot.child("answer_one").getValue().toString();
radioButton1.setText(answer_one);
