如何通过活动发送ArrayList <CustomClass>（）

我有这个课：

public class FlightData implements Parcelable { private double x; private double y; private double time;

FlightData(double x, double y, double time){
    this.x = x;
    this.y = y;
    this.time = time;
}

private FlightData(Parcel in) {
    x = in.readDouble();
    y = in.readDouble();
    time = in.readDouble();
}


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

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeDouble(x);
    dest.writeDouble(y);
    dest.writeDouble(time);
}

public static final Creator<FlightData> CREATOR = new Creator<FlightData>() {
    @Override
    public FlightData createFromParcel(Parcel in) {
        return new FlightData(in);
    }

    @Override
    public FlightData[] newArray(int size) {
        return new FlightData[size];
    }
};

...

} 我尝试将其打包，然后是意图。但是我什至无法在同一个活动中检索它（它在另一个活动中抛出null，所以我也尝试在当前活动中获取它-null）：

    List<FlightData> flightDataList = new ArrayList<>();
    //... arraylist gets filled in
    intent = new Intent(this, DatasheetActivity.class);
    bundle = new Bundle();
    bundle.putParcelableArrayList("FlightDataList", (ArrayList<? extends Parcelable>) flightDataList);
    intent.putExtra("Bundle", bundle);

    Log.d("ErrorCustom",Integer.toString(flightDataList.size()));

//Log.d("ErrorCustom",Integer.toString(intent.getExtras().getParcelableArrayList("FlightDataList").size())); //throws null error

    startActivity(intent);

我确实想发送ArrayList，因为它被填充在当前活动中（带有进度条）。
