I want to retrieve four values as strings from my firebase database and add them to four textviews

Question

I currently have my code to retrieve just one and i don't want them in a listview, just in two textviews.

code to retrieve one:

fRef = new Firebase("https://sw1ft13s-6b875.firebaseio.com/users/" + userID);
fRef.addChildEventListener(new ChildEventListener() {
    @Override
    public void onChildAdded(com.firebase.client.DataSnapshot dataSnapshot, String s) {
        String kills = dataSnapshot.getValue(String.class);
        textViewUserkills.setText(kills);    `

and it retrieves just one succuessfully but i have more than one textview to retrieve to in the layout file

the layout file is:

</FrameLayout>

Use

fRef = new Firebase("https://sw1ft13s-6b875.firebaseio.com/users/" + userID);
fRef.addChildEventListener(new ChildEventListener() {
    @Override
    public void onChildAdded(com.firebase.client.DataSnapshot dataSnapshot, String s) {
        String kills = dataSnapshot.child("kills").getValue(String.class);
        textViewUserkills.setText(kills);
        String location=dataSnapshot.child("location").getValue(String.class);

and so on

thank you for your help... but, it doesnt retrieve back any data. unless i take out the " .child("kills") ". then it automatically retrieves the kills alone, ignoring the rest of the children (location, name, phonenumber). – Kalaiyo5 Jul 29 '17 at 10:39
Thanks for the concept ! – Kalaiyo5 Jul 29 '17 at 10:48

for this the best way is simply

What is the difference between ChildEventListener and ValueEventListener Firebase interfaces?

By changing the listener to valueEventListener(), retrieves the whole data for each value change.

fRef = new Firebase("https://sw1ft13s-6b875.firebaseio.com/users/" + userID);
fRef.addValueEventListener(new com.firebase.client.ValueEventListener() {
        @Override
        public void onDataChange(com.firebase.client.DataSnapshot dataSnapshot) {
            //String kills = dataSnapshot.getValue(String.class);
            String kills = dataSnapshot.child("kills").getValue(String.class);
            textViewUserkills.setText(kills);
            String location=dataSnapshot.child("location").getValue(String.class);
            textViewUserAddress.setText(location);

and so on! Thanks for the kick start from 'Martin De Simone'

Thanks for the kickstart? Is the same as the code i provided you — Martin De Simone, Jul 29 '17 at 14:51
