Android BottomSheetDialogFragment黑暗主题不适用

Question

我的问题是BottomSheetDialogFragment没有使用黑暗主题。我可以从OnCreateView手动更改主题，但它会破坏bottomomsheetdialog的动画，并且根视图正在消失。需要帮助。

public class FilterBottomSheetFragment : BottomSheetDialogFragment 
{
    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        //if (ThemeService.GetTheme(Context) == ThemeService.THEME_LIGHT)
        //{
        //    inflater.Context.SetTheme(Resource.Style.AppTheme_Light);
        //}
        //else if (ThemeService.GetTheme(Context) == ThemeService.THEME_DARK)
        //{
        //    inflater.Context.SetTheme(Resource.Style.AppTheme_Dark);
        //}

        return inflater.Inflate(Resource.Layout.filter_bottomsheet_dialog_alternate, container, false);
    }  
}

这就是我从mainActivity调用dialogfragment的方法;

FilterBottomSheetFragment filterBottomSheetFragment = new FilterBottomSheetFragment();
filterBottomSheetFragment.Show(SupportFragmentManager, "filterBottomSheetFragment");

活动继承自BaseActivity。

public class BaseActivity : AppCompatActivity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);

        if (ThemeService.GetTheme(this) == ThemeService.THEME_LIGHT)
        {
            SetTheme(Resource.Style.AppTheme_Light);
        }
        else if (ThemeService.GetTheme(this) == ThemeService.THEME_DARK)
        {
            SetTheme(Resource.Style.AppTheme_Dark);
        }
    }
}
