I am trying to retrieve an url from Firebase in Android. However, my problem is that I can't retrieve the url without also getting the unique key of the child.
The value I am trying to retrieve is the following:
Down below is the code I use to retrieve the data from firebase.
final FirebaseDatabase database = FirebaseDatabase.getInstance();
myRef = database.getReference().child("LoadItems");
myRef.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot child : dataSnapshot.getChildren() ){
String key;
key = child.getKey();
Log.d(TAG, "onDataChange: " + key);
Log.d(TAG, "onDataChange: " + child.getValue());
}
}
@Override
public void onCancelled(DatabaseError databaseError) { }
});
So what I am trying to get is what the url alone.
There is no need to know any key in order to get that url. So please use my following lines of code:
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference shoesRef = rootRef.child("LoadItems").child("Shoes");
ValueEventListener valueEventListener = new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot ds : dataSnapshot.getChildren()) {
String url = ds.getValue(String.class);
Log.d(TAG, url);
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
Log.d(TAG, databaseError.getMessage()); //Don't ignore errors!
}
};
shoesRef.addListenerForSingleValueEvent(valueEventListener);
