不止一张地图片段有不同的标记

Question

我使用 android studio 应用程序。有 3 个用户（管理员、父母、司机）他们每个人都必须看到一张带有不同标记的地图，但是！！当我打开父母和司机活动时，我只看到管理标记！ 我尝试在打开地图之前清理标记，但它不起作用

AdminMapFragment：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.admin_map_fragment, container, false);

        // Get a reference to the SearchView


        SupportMapFragment supportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.ADMIN_MAP);
        supportMapFragment.getMapAsync(new OnMapReadyCallback() {
