Bottom Sheet Fragment 第二次调用时出错

Question

我有一个 class BottomSheetFragment extends BottomSheetDialogFragment，它包含子片段，我从片段中调用它。问题是，当我第二次调用它时，我的应用程序崩溃并出现 Binary XML file line #69: Duplicate id 0x7f090071, tag null, or parent id 0xffffffff with another fragmenterror.

底部 sheet class:

public class BottomSheetFragment extends BottomSheetDialogFragment {
    public BottomSheetFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v = inflater.inflate(R.layout.fragment_bottom_sheet, container, false);

        return v;
    }


}

在其 XML 中包含一个子片段 public class CreateNotesFragment extends android.support.v4.app.Fragment

BottomSheetFragment class 在按钮单击时在另一个片段中调用，如下所示：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_all_works, container, false);

        createNew = view.findViewById(R.id.add_file_btn);


        createNew.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                MainActivity mainActivity = (MainActivity)getActivity();
                mainActivity.showBottomSheetDialogFragment();
            }
        });


        return view;
    }

这里是 MainActivity 中显示底部的方法 sheet:

public void showBottomSheetDialogFragment() {
            bottomSheetFragment = new BottomSheetFragment();
            bottomSheetFragment.show(getSupportFragmentManager(), bottomSheetFragment.getTag());
    }

我假设由于某种原因第二次调用 BottomSheetFragment 时 CreateNotesFragment 不再存在，但我该如何修复它？

谢谢。

更新
这是 fragment_bottom_sheet.xml

中的第 69 行

<fragment
            android:id="@+id/notes_fragment"
            android:name="com.app.parsec.secondary_fragments.CreateNotesFragment"

我还注意到，如果我从 XML 中删除这个片段，我可以打开 BottomSheetFragment 而不会出现任何崩溃，所以问题一定出在子片段上。

解决了
解决方案是动态地将片段添加到片段中，而不是通过 XML。所以，我的 BottomSheetFragment 现在看起来像这样：

public class BottomSheetFragment extends BottomSheetDialogFragment {
    public BottomSheetFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_bottom_sheet, container, false);
        getChildFragmentManager().beginTransaction().replace(R.id.fragment_here, new CreateNotesFragment()).commit();
        return v;
    }


}

Answer 1

您正在尝试打开同一个片段。当前片段应该被关闭。 bottomSheetFragment.dismiss(); 然后 bottomSheetFragment.show(getSupportFragmentManager(), tag)

你可以尝试给片段一个不同的标签。

public void showBottomSheetDialogFragment() {
       bottomSheetFragment = new BottomSheetFragment();
       bottomSheetFragment.show(getSupportFragmentManager(), bottomSheetFragment.getTag());
}

编辑：

此错误发生在已在布局中定义的嵌套片段上，请尝试从 XML 布局中删除您的片段并将其替换为 FrameLayout，然后在代码中动态实例化您的片段。

Answer 2

您在 YourFragment 的 XML 文件中调用片段标记，基本上，将 bottom sheet 添加到片段 的方法是错误的。以下是您可以做到的方式：

点击按钮调用此方法：

callToGuideShareDialog();

给底部充气Sheet在这个方法里面查看

private void callToGuideShareDialog() {
final View viewBottom = DataBindingUtil.inflate(getLayoutInflater(), R.layout.------, null, false).getRoot();
            ImageView imageView = viewBottom.findViewById(R.id.img_size_guide_share);
            TextView textViewMsg = viewBottom.findViewById(R.id.----);
            viewBottom.findViewById(R.id.-----).setOnClickListener(this);
            TextView textViewMeasurement = viewBottom.findViewById(R.id.----);

        sheetDialog = new BottomSheetDialog(context);
        sheetDialog.setContentView(viewBottom);

        viewBottom.post(new Runnable() {
            @Override
            public void run() {
                BottomSheetBehavior mBehavior = BottomSheetBehavior.from((View) viewBottom.getParent());
                mBehavior.setPeekHeight(viewBottom.getHeight());
            }
        });

        if (sheetDialog != null)
            sheetDialog.show();
}

Bottom Sheet Fragment 第二次调用时出错
