Java Android:getParcelable返回空值？

作为我最后一个问题的后续内容：

我现在正试图通过Parcelable传递我的ArrayList。但是，当从其他活动获取时，它返回null。我似乎不明白为什么。我有以下几点

ResultsList.java

 public class ResultsList extends ArrayList<SearchList> implements Parcelable {

    /**
 * 
 */
private static final long serialVersionUID = -78190146280643L;

 public ResultsList(){

}

public ResultsList(Parcel in){
    readFromParcel(in);
}

@SuppressWarnings({ "rawtypes" })
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
    public ResultsList createFromParcel(Parcel in) {
        return new ResultsList(in);
    }

    public Object[] newArray(int arg0) {
        return null;
    }

};

private void readFromParcel(Parcel in) {
    this.clear();

    //First we have to read the list size
    int size = in.readInt();

    //Reading remember that we wrote first the Name and later the Phone Number.
    //Order is fundamental

    for (int i = 0; i < size; i++) {
        String title = in.readString();
        String Des = in.readString();
        String message = in.readString();
        SearchList c = new SearchList(title,Des,link);
        this.add(c);
    }

}

public int describeContents() {
    return 0;
}

public void writeToParcel(Parcel dest, int flags) {
    int size = this.size();
    //We have to write the list size, we need him recreating the list
    dest.writeInt(size);
    //We decided arbitrarily to write first the Name and later the Phone Number.
    for (int i = 0; i < size; i++) {
        SearchList c = this.get(i);
        dest.writeString(c.gettitle());
        dest.writeString(c.getDescription());
        dest.writeString(c.getmessage());
    }
}
 }

listOfResults

声明为

resultslistofResults=newresultslist（）并在前面的代码中填充，然后将其与

Intent intent = new Intent(this ,newthing.class);
    Bundle b = new Bundle();
    b.putParcelable("results", listOfResults);
    startActivityForResult(intent,0);

接收

    Bundle extras = getIntent().getExtras();
    ResultsList results = extras.getParcelable("results");

我想指出的是，我正在通过检查进入捆绑包的Arraylist的size（），然后检查出来，来测试这个空值。它可以很好地输入，但输出为空。
未将捆绑包附加到intent！（doh！）被IRC上一位善良的绅士指出#安卓开发

    Bundle extras = getIntent().getExtras();
    ResultsList results = extras.getParcelable("results");
