如何解决 java.lang.RuntimeException: Parcelable 写序列化对象遇到IOException
How to solve java.lang.RuntimeException: Parcelable encountered IOException writing serializable object
在我的 Android 应用程序中，我想将我的自定义对象传递给另一个 activity.I 我正在使用意图
Intent i = new Intent(A.this,B.class);
i.putExtra ("Object", myObject);
context.startActivity (i);
正在调用activity
MyObject myObject = (MyObject) intent.getSerializableExtra ("Object");
当我 运行 它显示的应用程序
时，我还在我的模型 class.But 中实现了 Serilizable
java.lang.RuntimeException: Parcelable encountered IOException writing serializable object
日志显示了这一点
