Android BottomSheetDialogFragment结果到启动它的片段

我正在尝试侦听或将数据从BottomSheetDialogFragment传递到Fragment以更改片段上的内容，在按钮上单击我在Homefragment中显示BottomSheetDialogFragmentin，BottomSheetDialogFragmentwill将执行API调用，如果成功，它将关闭BottomSheetDialogFragment并执行Homefragment中的第二个API调用，在第二个API调用成功时，我将使textview可见性消失在Homefragment中，这会给我带来NullpointerException
