【问题描述】：

您好，我有一个 bottomsheet 和一些 textViews（作为按钮），当按下它时它会导航到一个不同的片段，但问题是当按下 textView 并导航到片段时，底部的工作表仍然没有隐藏点击屏幕以隐藏底部工作表，我希望在启动片段时底部工作表将隐藏，这是我遇到的问题的屏幕记录link

Profile_Fragment.java

 ImageView accountSettings = view.findViewById(R.id.account_Settings);
  accountSettings.setOnClickListener(
                v -> {
                    BottomSheet bottomSheet = new BottomSheet();
                    bottomSheet.show(requireActivity().getSupportFragmentManager(), bottomSheet.getTag());
                }
        );

BottomSheet.java

public class BottomSheet extends BottomSheetDialogFragment {

    public BottomSheet() {
    }

    @Nullable
    @org.jetbrains.annotations.Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable @org.jetbrains.annotations.Nullable ViewGroup container, @Nullable @org.jetbrains.annotations.Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.bottom_sheet_profile, container, false);
       

        TextView settingsProfileTextView = view.findViewById(R.id.settings);
        settingsProfileTextView.setOnClickListener(v -> {
            Fragment settings_profile = new Settings_Profile();
            FragmentTransaction transaction = getParentFragmentManager().beginTransaction();
            transaction.add(R.id.fragment_container, settings_profile);
            transaction.addToBackStack(String.valueOf(settings_profile));
            transaction.commit();
          
        });
        TextView editProfileTextView = view.findViewById(R.id.edit_profile);
        editProfileTextView.setOnClickListener(v -> {
            Fragment edit_profile = new Edit_Profile();
            FragmentTransaction transaction = getParentFragmentManager().beginTransaction();
            transaction.add(R.id.fragment_container, edit_profile);
            transaction.addToBackStack(String.valueOf(edit_profile));
            transaction.commit();
        });
        return view;
    }
}

Edit_Profile.java // 按下 textView 时正在打开的片段

  @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable @org.jetbrains.annotations.Nullable ViewGroup container, @Nullable @org.jetbrains.annotations.Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_edit_profile, container, false);
        profilePhoto = view.findViewById(R.id.circleImageView);
        initImageLoader();
        setProfileImage();
        ImageView imageView = view.findViewById(R.id.backArrow);
        imageView.setOnClickListener(v -> {
            Fragment newCase = new Profile_Fragment();
            assert getFragmentManager() != null;
            FragmentTransaction transaction = getFragmentManager().beginTransaction();
            transaction.replace(R.id.fragment_container, newCase);
            transaction.disallowAddToBackStack();
            transaction.commit();
        });

        return view;
    }

【问题讨论】：

在 settingsProfileTextView 点击监听器中的 transaction.commit() 之前添加这些行。 mBottomSheetBehavior.setHideable(true); mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN);
对不起，我添加了它，但它不起作用

【解决方案1】：

您的BottomSheet 由BottomSheetDialogFragment 托管。在内部，它有一个Dialog，可以使用dismiss() 解除，最终将解除BottomSheet。

在提交片段事务时在您的代码中应用它：

    settingsProfileTextView.setOnClickListener(v -> {
        Fragment settings_profile = new Settings_Profile();
        FragmentTransaction transaction = getParentFragmentManager().beginTransaction();
        transaction.add(R.id.fragment_container, settings_profile);
        transaction.addToBackStack(String.valueOf(settings_profile));
        transaction.commit();
        dismiss(); // Dismiss the Bottom sheet
      
    });
    TextView editProfileTextView = view.findViewById(R.id.edit_profile);
    editProfileTextView.setOnClickListener(v -> {
        Fragment edit_profile = new Edit_Profile();
        FragmentTransaction transaction = getParentFragmentManager().beginTransaction();
        transaction.add(R.id.fragment_container, edit_profile);
        transaction.addToBackStack(String.valueOf(edit_profile));
        transaction.commit();
        dismiss(); // Dismiss the Bottom sheet
    });
