在我的 Android 应用程序中，我想将自定义对象传递给另一个 Activity 。我正在使用 Intent 来实现
Intent i = new Intent(A.this,B.class);
i.putExtra ("Object", myObject);
context.startActivity (i);
在通话 Activity 中
MyObject myObject = (MyObject) intent.getSerializableExtra ("Object");
此外，我已经在我的模型类中实现了可序列化。但是当我运行应用程序时，它显示
java.lang.RuntimeException: Parcelable encountered IOException writing serializable object
日志显示了这一点

最佳答案
在堆栈跟踪中，您可以看到
Caused by: java.io.NotSerializableException: com.eventmate2.model.Age
Age 类未实现 Serialized 接口(interface)。实现将解决这个问题
