I have a Problem with Parcelable Data in an ArrayList sending via two Activities using Android.Bundle
I have two Activities (A and B).
In Aaaa.class:
ArrayList<Model> mModelList = new ArrayList<Model>
//Fill ArrayList with a few Model-Objects
Bundle mBundle = new Bundle;
Intent mIntent = new Intent(Aaaa.this, Bbbb.class);
mBundle.putParcelableArrayList("models", mModelList);
mIntent.putExtras(mBundle);
startActivity(mIntent);
In Bbbb.class:
Bundle mBundle = getIntent().getExtras();
ArrayList<Model> = mBundle.getParcelableArrayList("models");
The Model.class is implementing Parcelable.
So, the Problem is. When I fill the ArrayList (in Aaaa.class) and put it to the Bundle, I can see that the Bundle contains the varios Objects from the List. When I then try to fill the List in Bbbb.class a Exception is Thrown.

Line52 is
ArrayList<Model> = mBundle.getParcelableArrayList("models");
I have absolutly no Idea where is the Problem here, the Model.class is working fine with other Bundle - Intents.
Update:
The Model Class as followed.
public class Model implements Parceleble{
private String name;
private String address;
public Model(Parcel parcel){
}
public Model(){
}
public Model(String name, String address){
this.name = name;
this.address = address;
}
//Getter and Setter
//equals, HashCode, toString (autoGenerated from Idea)
@Override
public void writeToParcel(Parcel parcel, int i){
parcel.writeString(name);
parcel.writeString(address);
}
public void readFromParcel(Parcel parcel){
this.name = parcel.readString();
this.address = parcel.readString();
}
public static Parcelable.Creator<Model> CREATOR = new Parcelable.Creator<Model>(){
@Override
public Model createFromParcel(Parcel parcel){
return new Model(parcel);
}
@Override
public Model[] new Array(int size){
return new Model[size]
}
};
}
Your Parceleble implementation doesn't look quite correct to me, check out the sample code in API to see what are the required method/constructor that need to be overridden:
... ...
// ==================== Parcelable ====================
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel parcel, int flags) {
parcel.writeString(name);
parcel.writeString(address);
}
private Model(Parcel in) {
name = in.readString();
address = in.readString();
}
public static final Parcelable.Creator<Model> CREATOR = new Parcelable.Creator<Model>() {
public Model createFromParcel(Parcel in) {
return new Model(in);
}
public Model[] newArray(int size) {
return new Model[size];
}
};
... ...
Try this code and see if it helps.
