The error occured because user.get("lname") does not explictly return a String.

You should call toString() or better if your sure that this is a String declare it when you declare your hashmap HashMap<String, String> user = new HashMap<String, String>();

lname.setText(user.get("lname"));

It seems that user.get("lname") doesn't return a String, yet setText accepts String as parameter.

Try to converse it to a String, or call the toString method on the result.
