我正在尝试将自定义对象的arraylist从一个活动传递给另一个。 arrayList包含非常简单的对象。这是班级：
public class MaPin implements Serializable{
private Location pLocation;
private String pMessage;
public MaPin(Location location, String message){
this.pLocation = location;
this.pMessage = message;
}
public Location getpLocation() {return this.pLocation; }
public String getpMessage(){ return this.pMessage; }
}
如您所见，它实现了可序列化。然后根据这篇文章：Pass arraylist of user defined objects to Intent android，使用Data Wrapper很方便。所以我用了一个：
public class DataWrapper implements Serializable {
private ArrayList<MaPin> mMapArr;
public DataWrapper(ArrayList<MaPin> data) { this.mMapArr = data; }
public ArrayList<MaPin> getmMapArr() { return this.mMapArr; }
}
其中也实现了serializable。
要将数据从一个活动传递到另一个活动，我在原始活动上使用它：
Intent intent = new Intent(MainActivity.this, HistoryActivity.class);
intent.putExtra(EXTRA_MESSAGE, new DataWrapper(mMapinHistory));
startActivity(intent);
mMapinHistory是“MaPin”的ArrayList。
接收我在目的地活动上使用它：
Intent intent = getIntent();
DataWrapper wp = (DataWrapper) getIntent().getSerializableExtra(MainActivity.EXTRA_MESSAGE);
mPositionHistory = wp.getmMapArr();
所以你可以看到我认为我尊重帖子中提到的内容。但是，我仍然有以下错误：
java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = ovh.trimard.locapp.DataWrapper)
我不知道为什么DataWrapper和MaPin都可以实现序列化！
我做错了什么？
