Serializable
を実装するDataWrapperを使用して、ArrayListオブジェクトを別のアクティビティに渡します。
私はここで提供される答えに従いました: ユーザー定義オブジェクトのarraylistをIntent Androidに渡す 。MPAndroidChart
ライブラリPieChart
のOnChartGestureListener()
から別のアクティビティを開始しています。これは、ArrayListオブジェクトthreadList
を渡す方法です。
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);
}
//.....
}
私は次のようにDataWrapperクラスを実装しました:
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;
}
}
そしてParcelable encountered IOException writing serializable object
エラー。ここに私のLogcatがあります:

上記のリンクで(配列リストオブジェクトを渡すために)回答をたどりましたが、エラーが発生しました。エラーの原因と削除方法は?
OneThread
クラスもSerializable
を実装する必要があります。すべてのサブクラスと内部サブクラスはSerializable
を実装する必要があります。
