我有一个FragmentActivity,我想在其中使用一个地图片段.我在获取支持片段管理器访问它时遇到问题.

 if (googleMap == null) {
            googleMap = ((SupportMapFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.map1)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }

            // create marker
            MarkerOptions marker = new MarkerOptions().position(
                    new LatLng(latitude, longitude)).title("Hello Maps ");

            CameraPosition cameraPosition = new CameraPosition.Builder()
                    .target(new LatLng(latitude, longitude)).zoom(15).build();

            googleMap.animateCamera(CameraUpdateFactory
                    .newCameraPosition(cameraPosition));

            // adding marker
            googleMap.addMarker(marker);

我试图在点击侦听器中使用底部工作表，但我在这一行收到错误。

BottomSheetFragment.show(getSupportFragmentManager())

无法解析方法“show(?, java.lang.String)”无法解析方法“getSupportFragmentManager()”

我想在片段类中使用底部工作表。

SubCategoryDe​​tailFragment.java

  public class SubCategoryDetailFragment extends Fragment {

        TextView txtv_sort;

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View view= inflater.inflate(R.layout.fragment_sub_category_detail, container, false);
            toolbar = ((MainActivity) getActivity()).findViewById(R.id.toolbar);
            toggle = ((MainActivity) getActivity()).getToggle();
            shimmerContainer = view.findViewById(R.id.shimmer_view_container);
            recyclerView_subcatDetail = view.findViewById(R.id.recycler_view_subCategoryDetail);

           txtv_sort = view.findViewById(R.id.txtv_sort);

            toggle.setDrawerIndicatorEnabled(false);
            toggle.setHomeAsUpIndicator(R.drawable.back);
            toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    getActivity().onBackPressed();
                }
            });


         txtv_sort.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    BottomSheetFragment bottomSheetFragment = new BottomSheetFragment();
                    bottomSheetFragment.show(getSupportFragmentManager(), bottomSheetFragment.getTag());
                }
            });

            return view; …
