I'm trying to parcel an object which contains some string/int variables and an object variable. The strings and int's are working, but not the nested object. I understand I would have to it also parcelable, but I'm apparently doing something wrong=. In my nested class, the writeToParcel method gets called (I check with a Log.d() call), but the createFromParcel() doesn't. I end up getting a null object. This is my simplified code:
public class MyClass implements Parcelable {
public MyClass() {
}
private Integer id;
private String name;
private MyOtherClass otherClass = new MyOtherClass();
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public OtherClass getOtherClass() {
return otherClass;
}
public void setOtherClass(OtherClass otherClass) {
this.otherClass = otherClass;
}
public static final Parcelable.Creator<MyClass> CREATOR
= new Parcelable.Creator<MyClass>() {
public MyClass createFromParcel(Parcel in) {
return new MyClass(in);
}
public MyClass[] newArray(int size) {
return new MyClass[size];
}
};
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(id);
dest.writeParcelable(otherClass, flags);
}
private MyClass(Parcel in) {
name = in.readString();
id = in.readInt();
otherClass = (OtherClass) in.readParcelable(OtherClass.class.getClassLoader());
}
}
class MyOtherClass implements Parcelable {
public OtherClass() {
}
private String resourcePreviewURL;
public String getResourcePreviewURL() {
return resourcePreviewURL;
}
public void setResourcePreviewURL(String resourcePreviewURL) {
this.resourcePreviewURL = resourcePreviewURL;
}
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel out, int flags) {
Log.d("parcel", "write to parcel"); // this gets called
out.writeString(resourcePreviewURL);
}
public static final Parcelable.Creator<MyOtherClass> CREATOR
= new Parcelable.Creator<MyOtherClass>() {
public MyOtherClass createFromParcel(Parcel in) {
Log.d("parcel", "create from parcel"); // this doesn't get called
return new MyOtherClass(in);
}
public ResourcePreviews[] newArray(int size) {
return new ResourcePreviews[size];
}
};
private OtherClass(Parcel in) {
Log.d("parcel", "read from parcel"); // this doesn't get called
resourcePreviewURL = in.readString();
}
}
