android - 解码时出现ClassNotFoundException:io.realm.NeedRealmProxy $$ Parcelable

从片段HomeFragment运行此代码片段时出现此错误。

public void onTaskClick(View view, Need need, int position) {
    Log.d(TAG, "onTaskClick() - " + need.toString());

    Intent intent = new Intent(getActivity(), TaskDetailsActivity.class);

    Bundle bundle = new Bundle();
    bundle.putParcelable(TaskDetailsActivity.EXTRA_OBJ_NEED, Parcels.wrap(need));

    startActivity(intent, bundle);

这里是realmlistparcelconverter.java

public class RealmListParcelConverter implements

    @Override

        parcel.writeInt(input == null ? NULL : input.size());
        if (input != null) {
            for (RealmObject item : input) {
                parcel.writeParcelable(Parcels.wrap(item), 0);
            }
        }
    }

    @Override
    public RealmList fromParcel(android.os.Parcel parcel) {
        int size = parcel.readInt();
        RealmList list = new RealmList();
        for (int i=0; i<size; i++) {
            Parcelable parcelable = parcel.readParcelable(getClass().getClassLoader());
            list.add((RealmObject) Parcels.unwrap(parcelable));
        }
        return list;

最佳答案

您应该传递id，然后在另一侧按id拉出对象。
类似于：

public void onTaskClick(View view, Need need, int position) {
    Log.d(TAG, "onTaskClick() - " + need.toString());

    Intent intent = new Intent(getActivity(), TaskDetailsActivity.class);
    intent.putExtra("need_id", need.getId());
    startActivity(intent);
}

然后在接收id的活动中，将对象取回。

// in onCreate(), onHandleIntent(), etc.
// get the needId back out.
String needId = intent.getStringExtra("need_id");

// get the object out by id.
realm.where(Need.class).equalTo("id", needId).findFirst();

// Lookup by PK is super fast, but if you want you can always use
realm.where(Need.class).equalTo("id", needId).findFirstAsync();
// This will make this microsecond lookup happen on a background thread
// and return the object back to you on your main thread, but is
// probably overkill for a single object.
