Question

我目前尝试使用Android的 Fabulous筛选器库（Link）制作一个Floating Button，以打开一个带有动画的Fragment Dialog。

我想将其用作过滤器片段对话框，允许用户选择日期，然后将所选日期传递回屏幕（我使用片段而不是活动）。

即使我遵循了文档代码，回调似乎也不起作用。

我的问题：

当我关闭override fun onResult(result: Any?)时，Fragment Dialog永远不会被调用/运行，是否执行不正确，所以回调函数永远不会被调用？

我的愿望结果：

如何使用其回调函数将数据（选定的日期）从Fragment Dialog传递到屏幕（片段）？

我的屏幕课程（片段）

class DashboardFragment : Fragment(), AAH_FabulousFragment.Callbacks {

    override fun onResult(result: Any?) {
        Log.d("k9res", "onResult: " + result.toString());
        if (result.toString() == "swiped_down") {
            //do something or nothing
        } else {
            //handle result
        }
    }

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_dashboard, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        floatingActionButton2.setOnClickListener {
            val dialogFrag = HistoryFilterFragment.newInstance()
            dialogFrag.setParentFab(floatingActionButton2)
            dialogFrag.show(this.fragmentManager, dialogFrag.tag)
        }
    }
}

片段对话框类

class HistoryFilterFragment : AAH_FabulousFragment() {

    override fun setupDialog(dialog: Dialog, style: Int) {
        val contentView = View.inflate(context, R.layout.fragment_history_filter, null)
        val rl_content = contentView.findViewById(R.id.rl_content) as RelativeLayout
        contentView.button2.setOnClickListener { closeFilter("closed") }

        setAnimationDuration(500) 
        setPeekHeight(400)

        // Callback Function Here
        setCallbacks(targetFragment as AAH_FabulousFragment.Callbacks?) //optional; to get back result
        setAnimationListener(targetFragment as AAH_FabulousFragment.AnimationListener?) //optional; to get animation callbacks

        setViewMain(rl_content) 
        setMainContentView(contentView) 
        super.setupDialog(dialog, style)
    }

    companion object {

        fun newInstance(): HistoryFilterFragment {
            return HistoryFilterFragment()
        }
    }

}

如何使用Android Fabulous Filter回调传递数据？
