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：
