将 Parent 视图发送到 child (BottomSheetDialogFragment)

Question

今天我想知道是否可以这样做。我的意思是，当我加载 child 视图时发送 parent 视图。换句话说，我想在 child.

上处理 parent

Parent 查看

  imgFilter.setOnClickListener {
            MyDialogFragment().show(requireActivity().supportFragmentManager,"filter_dialog")
        }

Child 查看

class MyDialogFragment : BottomSheetDialogFragment() {
    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog

    val view = View.inflate(context, R.layout.filter_sheet_layout, null)

    val linearLayout = view.findViewById<LinearLayout>(R.id.root)
    val params = linearLayout.layoutParams as LinearLayout.LayoutParams
    params.height = getScreenHeight()
    linearLayout.layoutParams = params

    backArrowClick(view)
    hideKeyboard()


    dialog.setContentView(view)
    mBehavior = BottomSheetBehavior.from(view.parent as View)

    parentFragment?.view?.findViewById<TextView>(R.id.name_store)?.text = "Hello World"

    return dialog
}
}

如果可能，我不会这样做，或者如果您有其他建议，我会在这里听取和学习。

非常感谢！

问题是 show 方法正在接收来自 activity 的片段管理器作为参数，因此它找不到父片段

MyDialogFragment().show(childFragmentManager, "filter_dialog")

应该允许 parentFragment?.view? 被发现。
