I need help on getting the "message" Object from this DataSnapshot result

DataSnapshot { key = user-4, value = {-JvFuwKX7r7o0ThXc0x8={sender=unit_owner, message=fkfkgkgkgkggkgkgkgkgkgkgkgkgkgkgkgkglgkgkgkgkgkgkgkg, role=unit_owner, profile_image=http://54.169.41.20/assets/boy-862a2e9036b094973c04afa1c0365a45.png, name=Paul Bartbartbart}} }

I am able to get the key value by getKey() and I have JvFuwKX7r7o0ThXc0x8 as an Object as well, this is an automatic FireBase generated name of the object. Instead of listening to the object itself. How can I navigate trough, "sender" or "message" and getting its value by using DataSnapshot member methods?

I looks like you're adding a value listener to something that has multiple children. I'm guessing it's a limitToLast(1) query, but it would be really helpful if you include the code in your question. Until you do add it however, this is my guess of what your code looks like:

Firebase ref = new Firebase("https://yours.firebaseio.com");

Query messages = ref.orderByKey().limitToLast(1);

messages.addValueEventListener(new ValueEventListener() {

    @Override

    public void onDataChange(DataSnapshot dataSnapshot) {

        Log.i("Messages", dataSnapshot.toString());

    }



    @Override

    public void onCancelled(FirebaseError firebaseError) {



    }

})

While you are limiting the filter to single message, you are still a list of messages. It's just a list of only 1 message.

This means that on onDataChange you will still need to drill down into the child. Since you cannot do that by index, you will need to use a for loop:

public void onDataChange(DataSnapshot dataSnapshot) {

    for (DataSnapshot chatSnapshot: dataSnapshot.getChildren()) {

        String message = (String) chatSnapshot.child("message").getValue();

        String sender = (String) chatSnapshot.child("sender").getValue();

    }

}

Note that this gets a lot more readable if you take a moment to create a Java class that represents the message:

public class Chat {

    String message;

    String sender;

    public String getMessage() { return message; }

    public String getSender() { return sender; }

}

Then you can get the message with:

public void onDataChange(DataSnapshot dataSnapshot) {

    for (DataSnapshot chatSnapshot: dataSnapshot.getChildren()) {

        Chat chat = chatSnapshot.getValue(Chat.class);

        String message = chat.getMessage();

        String sender = chat.getSender();

    }

}

The above snippet still needs the for loop, since you're still getting a list of 1 messages. If you want to get rid of that loop, you can register a child event listener:

query.addChildEventListener(new ChildEventListener() {

    @Override

    public void onChildAdded(DataSnapshot dataSnapshot, String s) {

        Chat chat = dataSnapshot.getValue(Chat.class);

        String message = chat.getMessage();

        String sender = chat.getSender();

    }



    // other overridden messages have been removed for brevity



})

Firebase will call the onChildAdded() method for each child, so you don't have to look over them yourself.

The value will be returned as an Object, as you've stated, but you can actually cast it to Map<String, Object> since you know it should be a map.

So, do something like this:

Map<String, Object> val = (Map<String, Object>) dataSnapshot.getValue();

String message = (String) val.get("message");

String sender = (String) val.get("sender");
