导致异常的Pracelable对象的ArrayList

标签： java android arraylist parcelable

当我将Parcelable对象的arraylist传递给GCM服务时，我得到了异常。 非常感谢帮助。

这不是其他一些问题（如this one）的情况，他们在一个parcelable对象中有一个ArrayList。我有一个parcelable对象的ArrayList

我有以下Parcelable类：

public class PreferencesLeg implements Parcelable {

public int index;
public int pref1;
public int pref2;

public PreferencesLeg(int index, int pref1, int pref2) {
    this.index = index;
    this.pref1 = pref1;
    this.pref2 = pref2;
}


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

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeInt(this.index);
    dest.writeInt(this.pref1);
    dest.writeInt(this.pref2);
}

protected PreferencesLeg(Parcel in) {
    this.index = in.readInt();
    this.pref1 = in.readInt();
    this.pref2 = in.readInt();
}

public static final Creator<PreferencesLeg> CREATOR = new Creator<PreferencesLeg>() {
    public PreferencesLeg createFromParcel(Parcel source) {
        return new PreferencesLeg(source);
    }

    public PreferencesLeg[] newArray(int size) {
        return new PreferencesLeg[size];
    }
};
}

我正在使用此课程如下：

Bundle extras = new Bundle();
ArrayList<PreferencesLeg> preferencesLegs = new ArrayList<>();
for (Leg leg : legList.legs) {

    PreferencesLeg preferencesLeg = new PreferencesLeg(leg.index, leg.pref1,
            leg.pref2);
    preferencesLegs.add(preferencesLeg);
}
extras.putParcelableArrayList(PREFERENCES_LEGS, preferencesLegs);


OneoffTask oneoffTask = new OneoffTask.Builder()
        .setService(UpdatePreferencesService.class)
        .setTag(unique_id)
        .setExtras(extras)
        .setExecutionWindow(0.0F, 10.0F)
        .setRequiredNetwork(Task.NETWORK_STATE_CONNECTED)
        .setUpdateCurrent(true)
        .build();

GcmNetworkManager.getInstance(this).schedule(oneoffTask);

...

public class UpdatePreferencesService extends GcmTaskService {
    @Override
    public int onRunTask(TaskParams taskParams) {

        String id = taskParams.getTag();
        Bundle extras = taskParams.getExtras();

        ArrayList<PreferencesLeg> preferencesLegs = extras.getParcelableArrayList(PREFERENCES_LEGS);


...

我尝试运行任务时遇到异常：

您可以尝试直接设置ClassLoader。

extras.setClassLoader(PreferencesLeg.class.getClassLoader());
