请问在广播接收器中如何获取自定义对象？

Question

发送：
 Intent intent=new Intent(TestActivity2.this,
                        BroadcastReceiverGPS.class);
                intent.setAction("com.xyz");
//                传输对象测试
                SvStatus svStatus=new SvStatus();
                svStatus.setB(1);
                svStatus.setB1(1);
                svStatus.setB2(1);
                svStatus.setC(1f);
                svStatus.setC(1f);
                intent.putExtra("sv",svStatus);
                sendBroadcast(intent);

接收
public void onReceive(Context context, Intent intent) {
        String acion=intent.getAction().toString();
        switch (acion){
            case ACTION1:
                Log.i(TAG,"reciver the abc...");
                break;
            case ACTION2:
                Log.i(TAG,"reciver the xyz...");
//                Object o= (intent.getSerializableExtra("sv"));
//                SvStatus svStatus=(SvStatus)o;
//                Log.i(TAG,"sv:"+svStatus.getB());
                SvStatus s=intent.getParcelableExtra("sv");
                Log.i(TAG,"sv:"+s.getB());
                break;
            default:
        }
    }

你先确认一下27行能不能拿到内容,是没set进去,还是取的方式不对
