Android Class Parcelable with ArrayList

Question

I have an android project where I have a class. In that class is an ArrayList. I will be getting some XML, parsing it out, then making objects ou

Answer 1

Create a new java file for "Choices" and implement "Parcelable". If you do not implement parcelable you will get run-time exception (Unable to Marshal). So use the code below :

    public class Choices implements Parcelable{

        boolean isCorrect;
        String choice;

        public Choices(boolean isCorrect, String choice) {
            this.isCorrect = isCorrect;
            this.choice = choice;
        }
        //Create getters and setters 

        protected Choices(Parcel in) {
            isCorrect = in.readByte() != 0;
            choice = in.readString();
        }

        public static final Creator CREATOR = new Creator() {
            @Override
            public Choices createFromParcel(Parcel in) {
                return new Choices(in);
            }

            @Override
            public Choices[] newArray(int size) {
                return new Choices[size];
            }
        };

        @Override
        public String toString() {
            return "Choices [isCorrect=" + isCorrect + ", choice=" + choice
                    + "]";
        }

        @Override
        public int describeContents() {
            return 0;
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
            dest.writeByte((byte) (isCorrect ? 1 : 0));
            dest.writeString(choice);
        }
    }

As mentioned in above answer by @G.Blake you need to make Choices Parcelable and Android knows how to parcel ArrayLists of Parcelables
