i found solution,this is that code
String pris="super Creamcracker";
DatabaseReference ref=FirebaseDatabase.getInstance().getReference().child("Items");
ref.orderByChild("Name").equalTo(pris).addValueEventListener(new ValueEventListener(){
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot datas: dataSnapshot.getChildren()){
String keys=datas.child("Price").getValue().toString();
pric.setText(keys);
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
I don't think so it is possible. Will let you know if find any solution.
