Hello,
I have a small problem, hope you can help me.
I want to pass one object of class A from one Android Activity to
another and I need to use Parcelable (performance and Class loading
issues). My code is similar to the lines listed below:
class A implements Parcelable {
private String x; //other fields here...
private B b;
......
public void writeToParcel(Parcel out, int i) {
out.writeString(x);
out.writeParcelable(b, i);
}
public static Parcelable.Creator CREATOR = new Parcelable.Creator
() {
public A createFromParcel(Parcel in) {
A result = new A();
result.x= in.readString();
result.b = in.readParcelable(getClass().getClassLOader
());
return result;
}
}
}
class B implements Parcelable {...}
// Sending Parcelable ....
bundle.putParcelable(KEY1, a);
bundle.putSerializable(KEY2, something);
bundle.putParcelable(KEY3, otherParcelableObject);
//Receiving Parcelable...
@Override
public void onCreate(Bundle icicle) {
Bundle receivedBundle = getIntent().getExtras()
Object o= receivedBundle.getParcelable(KEY3)
// Problem: "o" is NULL here
// Debug: receivedBundle.mMap= HashMap{ [something, null],
[Map { [KEY3, other], [null,null] }, KEY2], [KEY1, a] }
If I remove from class A the code that writes B into Parcel,
receivedBundle.mMap has the expected value: HashMap {[KEY1, a], [KEY2,
something], [KEY3, other]}.
Am I doing something wrong or is the parcelization mechanism not
supporting recursive Parcelable entities?
Thanks in advance,
Lia.
