Question

我正在开发一个餐厅计划。我遇到了问题。现在我将告诉您产品选择过程中发生的事件

**该应用程序由两个片段组成。活动名称是＆＃39; MasaDetay＆＃39;。 FragmentOne名称是＆＃39; MasaUrunler＆＃39;，FragmentTwo名称是＆＃39; MasaAdisyon＆＃39; **

＆＃39; MasaUrunler＆＃39;中的操作片段

我带着Volley带来数据库中的产品，我将它们列在屏幕上，这要归功于RecycleView
我打印列出的产品，并在另一项活动中选择这些产品的数量，份数和属性
我获取了onActivityResult函数中的所有数据
我将数组中保存的数据发送到另一个片段

在＆＃39; MasaAdisyon＆＃39;片段，发生以下事件

我正在 onCreateView 中执行LayoutManager事件，并绑定适配器和 RecycleViewAdapter
< / LI>
我在 RecyclerViewAdapter 的 getItemCount 函数中查看数组的大小。 在此步骤中，新数据不会进入RecycleViewAdapter

MasaUrunler Kotlin代码

var adapter : MasaAdisyonListesiAdapter? = null
var ADISYONLISTESI = ArrayList<AdisyonListesiBilgileri>()
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                          savedInstanceState: Bundle?): View? {

    var thisView = inflater.inflate(R.layout.fragment_masa_adisyon, container, false)
    var args = arguments
    var layoutManager = LinearLayoutManager(context, LinearLayoutManager.VERTICAL, false)
    thisView?.findViewById<RecyclerView>(R.id.masaAdisyonListesiRecycle)?.layoutManager = layoutManager
    adapter = MasaAdisyonListesiAdapter(ADISYONLISTESI)
    if(args?.getSerializable("ADISYONLISTESI") != null){
        ADISYONLISTESI = args?.getSerializable("ADISYONLISTESI") as ArrayList<AdisyonListesiBilgileri>
        adapter?.notifyDataSetChanged()
    }
    thisView?.findViewById<RecyclerView>(R.id.masaAdisyonListesiRecycle)?.adapter = adapter
    return thisView
}
inner class MasaAdisyonListesiAdapter(_ADISYONLISTESI : ArrayList<AdisyonListesiBilgileri>) : RecyclerView.Adapter<MasaAdisyonListesiAdapter.MasaAdisyonListesiViewHolder>(){
    var ADISYONLAR = _ADISYONLISTESI
    override fun getItemCount(): Int {
        Log.e("ADISYONBOYUTU",ADISYONLAR.size.toString())
        return ADISYONLAR.size
    }
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MasaAdisyonListesiViewHolder {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }
    override fun onBindViewHolder(holder: MasaAdisyonListesiViewHolder, position: Int) {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }
    inner class MasaAdisyonListesiViewHolder(itemView : View) : RecyclerView.ViewHolder(itemView) {

    }
}

MasaAdisyon Kotlin代码

String date = "24May2018";
LocalDate ldt = LocalDate.parse(date, DateTimeFormatter.ofPattern("ddMMMyyyy", Locale.US));
String result = ldt.format(DateTimeFormatter.ofPattern("dd-MM-yyyy",Locale.US));
=>24-05-2018

**我希望您的解决方案得到答案。谢谢*
