您可以将自定义对象传递给两个活动之间：

2.通过在你的类中实现Parcelable接口MyView

3.通过在你的类中实现Serializable接口MyView

是的，只有当您的自定义对象类实现Parcelable接口时才有可能。

一种选择可能是让您的自定义类实现 Serializable 接口，然后您可以使用 Intent#putExtra() 方法的 putExtra(Serializable..) 变体以额外的意图传递对象实例。

伪代码：

//to pass :
   intent.putExtra("MyClass", obj);  

// to retrieve object in second Activity
getIntent().getSerializableExtra("MyClass");
