Java 底页对话框片段

从映射片段调用

ScheduleFragment scheduleFragment = new ScheduleFragment();
scheduleFragment.showNow(getChildFragmentManager(),scheduleFragment.getTag());

public class ScheduleFragment extends BottomSheetDialogFragment {

public ScheduleFragment(){

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

}

计划片段

ScheduleFragment scheduleFragment = new ScheduleFragment();
scheduleFragment.showNow(getChildFragmentManager(),scheduleFragment.getTag());

public class ScheduleFragment extends BottomSheetDialogFragment {

public ScheduleFragment(){

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

}

现在我面临的问题是，每当应用程序恢复时，模式底部页似乎正在从隐藏状态更改为展开状态。是否有任何修复方法
