我无法在我的对象属性“ArrayList”上实现 Parcelable，显然我的属性“ArrayList 有效，为什么？因为，我使用相同的方法：
in.readTypedList(etapes,Step.CREATOR);
in.readTypedList(points, LatLng.CREATOR);//BUG
我的课，当然还有：“import com.google.android.gms.maps.model.LatLng;”
public class Road implements Parcelable {
public String depart;
public String arrivee;
public int distance;
public int duration;
public ArrayList<Step> etapes = new ArrayList<Step>();
public String travel_mode;
public LatLngBounds bounds;
public ArrayList<LatLng> points = new ArrayList<LatLng>();
public Road(String depart, String arrivee, int distance, int duration, ArrayList<Step> etapes, String travel_mode, ArrayList<LatLng> points){
this.depart = depart;
this.arrivee = arrivee;
this.distance = distance;
this.duration = duration;
this.etapes = etapes;
this.travel_mode = travel_mode;
LatLngBounds.Builder builder = new LatLngBounds.Builder();
for(int i=0; i<points.size();i++){
builder.include(points.get(i));
}
bounds = builder.build();
this.points = points;
}
private Road(Parcel in){
depart = in.readString();
arrivee = in.readString();
distance = in.readInt();
duration = in.readInt();
in.readTypedList(etapes,Step.CREATOR);//GOOD
travel_mode = in.readString();
LatLng ne = new LatLng(in.readDouble(),in.readDouble());
LatLng sw = new LatLng(in.readDouble(),in.readDouble());
LatLngBounds.Builder builder = new LatLngBounds.Builder();
builder.include(ne);
builder.include(sw);
bounds = builder.build();
in.readTypedList(points, LatLng.CREATOR);//BUG
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
dest.writeString(depart);
dest.writeString(arrivee);
dest.writeInt(distance);
dest.writeInt(duration);

dest.writeString(travel_mode);
dest.writeDouble(bounds.northeast.latitude);
dest.writeDouble(bounds.northeast.longitude);
dest.writeDouble(bounds.southwest.latitude);
dest.writeDouble(bounds.southwest.longitude);
dest.writeParcelable(bounds, flags);
dest.writeTypedList(points);
}
public static final Parcelable.Creator<Road> CREATOR =
new Parcelable.Creator<Road>() {
public Road createFromParcel(Parcel in){
return new Road(in);
}
public Road[] newArray(int size){
return new Road[size];
}
