绑定serviceio服务MainActivity

activity和fragment中的使用
@Override
public void onAttach(@NotNull Context context) {
super.onAttach(context);
RunSubject.getInstance().add(this);
RunSubject.getInstance().setObserverControl(this);
}
@Override
public void onDetach() {
super.onDetach();
RunSubject.getInstance().remove(this);
}
@Override
public void update(RunControlInfo runControlInfo) {
//更新消息处理
}
