org.greenrobot.eventbus.它的超级类没有带有@Subcribe注释的公共方法

Question

我正在使用EventBus来控制mediaplayer的状态，但是我在执行过程中遇到了一个错误。

原因：org.greenrobot.eventbus.事件总线异常：订阅者类maa. Mainactive及其超类没有带有@Subcribe注释的公共方法

 @Override
    public void onStart() {
        super.onStart();
        EventBus.getDefault().register(this);
    }

    @Override
    public void onStop() {
        EventBus.getDefault().unregister(this);
        super.onStop();
    }

    @Override
    protected void onDestroy() {
        radioManager.unbind();
        super.onDestroy();
        if (radioManager.isPlaying()) {
            radioManager.playOrPause(getPreference(getApplicationContext()));
        } else {
            radioManager.playOrPause(getPreference(getApplicationContext()));
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        radioManager.bind();
    }

    @Subscribe
    public void onEvent(String status) {
        switch (status) {
            case PlaybackStatus.LOADING:
                progressloading.setVisibility(View.VISIBLE);
                trigger.setVisibility(View.GONE);
                break;
            case PlaybackStatus.ERROR:
                Toast.makeText(this, R.string.no_stream, Toast.LENGTH_SHORT).show();
                break;
        }
        if (status.equals(PlaybackStatus.PLAYING)) {
            trigger.setVisibility(View.VISIBLE);
            progressloading.setVisibility(View.GONE);

        }
        trigger.setImageResource(status.equals(PlaybackStatus.PLAYING)
                ? R.drawable.ic_pause_black
                : R.drawable.ic_play_arrow_black);
    }

        if (service != null)
            EventBus.getDefault().post(service.getStatus());
    }

    public void unbind() {

        context.unbindService(serviceConnection);

    }

    private ServiceConnection serviceConnection = new ServiceConnection() {
        public void onServiceConnected(ComponentName className, IBinder binder) {
            RadioService.LocalBinder rl = (RadioService.LocalBinder) binder;
            service = rl.getService();
        }
        public void onServiceDisconnected(ComponentName arg0) {
            serviceBound = false;
        }
    };
}
