我想使用实现Serializable
的DataWrapper将我的ArrayList对象传递给另一个活动。
我按照这里提供的答案:Pass arraylist of user defined objects to Intent android
我正在MPAndroidChart
图书馆PieChart
OnChartGestureListener()
启动另一个活动。这是我传递我的ArrayList对象threadList
:
mChart.setOnChartGestureListener(new OnChartGestureListener() {
@Override
public void onChartSingleTapped(MotionEvent me) {
Intent intent = new Intent(MainActivity.this, TextersSmsActivity.class);
intent.putExtra("threadList", new DataWrapper(threadList));
MainActivity.this.startActivity(intent);
}
//.....
}
我像这样实现了DataWrapper类:
public class DataWrapper implements Serializable {
private static final long serialVersionUID = 100L;
private ArrayList<OneThread> threadList;
public DataWrapper(ArrayList<OneThread> threadList) {
this.threadList = threadList;
}
public ArrayList<OneThread> getThreadList() {
return threadList;
}
}
收到Parcelable encountered IOException writing serializable object
错误。
这是我的Logcat:

我按照上面链接中的答案(传递数组列表对象)但得到错误,导致错误的原因以及如何删除它?
答案 0 :(得分:39)
您的OneThread
班级也应该实施Serializable
。所有子类和内部子类都必须实现Serializable
。
