How to Retrieve a List object from the firebase in android

Question

I am having trouble retrieving a List from the Firebase. I have no trouble storing it, but as soon as I try to cast dataSnapshot.getValue() to ArrayList my app crashes, givi

Answer 1

A bit late, but in case any one else needs this.

IF the list is inside another object.

The object

public class Question {

    public Date date;
    public String questionNumber;
    public String questionText;
    public QuestionType questionType;
    public String multipleSelection1;
    public String multipleSelection2;
    public String multipleSelection3;

    public Question() {
        // Default constructor required for calls to DataSnapshot.getValue(User.class)
    }
}

Then to get your array of question objects

GenericTypeIndicator> t = new GenericTypeIndicator>() {};
List questionList = dataSnapshot.getValue(t);
