这是我从Serializable扩展的界面：
public interface InstaListener extends Serializable {
void onSuccess(String response);
void onFailure(int code, String reason);
}
以下是我在两个活动之间传递此监听器的方法：
InstaListener iListener = new InstaListener() {
@Override
public void onSuccess(String response) {
}
@Override
public void onFailure(int code, String reason) {
}
};
Intent intent = new Intent(activity, Insta.class);
intent.putExtra("email", email);
intent.putExtra("phone", phone);
intent.putExtra("purpose", purpose);
intent.putExtra("amount", amountstr);
intent.putExtra("name", name);
intent.putExtra("env", env);
intent.putExtra("listener", iListener);
activity.startActivity(intent);
以下是我在Insta类中接收侦听器的方式。
instaListener = (InstaListener) getIntent().getSerializableExtra("listener");
我搜索了很多帖子，但没有解释为什么我收到错误： java.io.NotSerializableException
任何帮助？
修改 发布异常和堆栈跟踪

答案 0 :(得分：1)
InstaListener的方法 - 本地实现是instamojo.library.InstamojoPay的内部类，它不是Serializable。您可能不希望它是Serializable，因此解决方案是将您的InstaListener实现编写为静态嵌套类，而不是方法本地内部类。
答案 1 :(得分：0)
你有一个内部类instamojo.library.InstamojoPay，它不可序列化。
要避免此异常，请将java.io.Serializable添加到内部类或将transient关键字添加到内部类对象声明
