BadParcelableException:Parcelable protocol requires a Parcelable 错误

在Android中的不同Activity之间传递对象，采用Bundle.putParcelable(Key, Object)时，在实现Parcelable接口的时候要注意一下方面；

/**

* 必须实现Parcelable.Creator接口，否则在获取该类数据的时候会报错
* 
* android.os.BadParcelableException:Parcelable protocol requires a
* Parcelable.Creator object called CREATOR on class
* 
* Parcelable.Creator接口实现了从Parcel容器读取本对象（Teacher）数据，并返回该对象给逻辑层使用
* 
* Parcelable.Creator接口对象名必须为CREATOR,否则同样会报上述同样的错误；
* 
* 在读取Parcel容器中的数据事，必须按成员变量声明的顺序来读取数据，不然会出现获取数据错误；
* 
* 反序列化对象

Teacher.java

Activity发送数据的主要代码

Teacher teacher = new Teacher();teacher.setName("老师");teacher.setAge(33);Intent intent = new Intent(First_Activity.this,Second_Activity.class);Bundle bundle = new Bundle();bundle.putParcelable("teacher", teacher);intent.putExtras(bundle);startActivity(intent);

Activity接收数据的主要代码

// 通过实现Parcelable接口后接收数据txt_5 = (TextView) findViewById(R.id.txt_5);Bundle bundle = getIntent().getExtras();Teacher teacher = (Teacher) bundle.getParcelable("teacher");txt_5.setText(teacher.getName() + "---" + teacher.getAge());
