捕获 BottomSheetDialogFragment 的解雇

Question

有什么方法可以捕获 BottomSheetDialogFragment 的 dismissal/cancel 吗？

底部sheetclass

public class ContactDetailFragment extends BottomSheetDialogFragment
{
    private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback()
    {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState)
        {
            if (newState == BottomSheetBehavior.STATE_HIDDEN)
            {
                dismiss();
            }
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset)
        {
        }
    };

    @Override
    public void setupDialog(Dialog dialog, int style)
    {
        super.setupDialog(dialog, style);
        View contentView = View.inflate(getContext(), R.layout.fragment_contactdetail, null);

        dialog.setContentView(contentView);

        BottomSheetBehavior mBottomSheetBehavior = BottomSheetBehavior.from(((View) contentView.getParent()));
        if (mBottomSheetBehavior != null)
        {
            mBottomSheetBehavior.setBottomSheetCallback(mBottomSheetBehaviorCallback);
            mBottomSheetBehavior.setPeekHeight((int) DisplayUtils.dpToPixels(CONTACT_DETAIL_PEEK_HEIGHT, getResources().getDisplayMetrics()));
        }
    }
}

我试过的方法都不行

在setupDialog中添加dialog.setOnCancelListener();或dialog.setOnDismissListener();永远不会被触发
底部sheet行为的onStateChanged仅在用户向下拖动底部sheet通过折叠状态时才会触发，dismissed/cancelled[没有状态] =32=]
通过使用 ContactDetailFragment.getDialog().setOnCancelListener() 将相同的 oncancel/ondismiss 侦听器添加到 BottomSheetDialogFragment 的实例化不会被触发

鉴于它本质上是一个对话片段，必须有某种方法来捕捉解雇？

Answer 1

找到一个简单的解决方案。在 BottomSheetDialogFragment 中使用 onDestroy 或 onDetach 可以让我正确地解雇
