使用parcelables在活动之间传递对象？

Question

所以我有一个浴室类，通过另一个活动中的按钮实现Parcelable和onClick：

Intent i = new Intent(getApplicationContext(), BathroomView1.class);

Bundle b = new Bundle(); 
b.putParcelable("myObject", this);
i.putExtras(b);
startActivity(i);

和我在onCreate里面的我的BathroomView1，我有：

loc = (Bathroom)this.getIntent().getExtras().getParcelable("myObject");

但我继续在该行上获取空指针异常。继承我的logcat：
