How can I get the value in Firebase Database with android?

Question

My Firebase Realtime Database is like this :

{Singer :
    Billie Eilish :
        01 :
            songType : \"type01\"
            songName : \"bad guy\"
             


        

Answer 1

why don't you just go with fetch data which contains only songType : type01 try this

DatabaseReference reference = FirebaseDatabase.getInstance().getReference();

Query query = reference.child("Singer").orderByChild("songType").equalTo("type01");
query.addListenerForSingleValueEvent(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        if (dataSnapshot.exists()) {
            for (DataSnapshot issue : dataSnapshot.getChildren()) {
                //set featched value to recyclerview 
            }
        }
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {

    }
});
