标签：androidframework layout item 面试 Koltin31 var android null id

import android.content.Intent

import android.view.LayoutInflater

import android.view.View

import android.view.ViewGroup

import androidx.recyclerview.widget.RecyclerView

import com.example.takeout.R

import com.example.takeout.model.beans.Order

import com.mob.wrappers.PaySDKWrapper

import org.jetbrains.anko.find

class OrderRvAdapter (val context: Context) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {

private var orderList: List = ArrayList()

fun setOrderData(orders: List) {

this.orderList = orders

notifyDataSetChanged()

}

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {

// val itemView = View.inflate(context, R.layout.item_order_item, null)

//TODO:没有填充满,原因是recycleview的孩子，测量模式是UNSPECIFY

//通过返回值已经addview,如果attachToRoot使用true会再一次addView()，就会报错

val itemView = LayoutInflater.from(context).inflate(R.layout.item_order_item,parent, false)

return OrderItemHolder(itemView)

}

override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {

val tvSellerName: TextView

val tvOrderType: TextView

//findviewbyId tv_order_item_seller_name tv_order_item_type

tvSellerName = item.find(R.id.tv_order_item_seller_name)

tvOrderType = item.find(R.id.tv_order_item_type) //订单状态

}

TakeoutService.kt使用Retrofit请求数据的封装

package com.example.takeout.model.net

import retrofit2.Call

import retrofit2.http.GET

interface TakeoutService {

//ex. @GET(“users/{user}/repos”)

//ex. fun listRepos(@Path(“user”) user: String): Call<List>

//http://127.0.0.1:8090/takeout?index=0

@GET(“takeout?index=0”)

fun getHomeInfo(): Call

//http://127.0.0.1:8090/takelogin?index=0

@GET(“takelogin?index=0”)

fun loginByPhone() : Call

//http://127.0.0.1:8090/takeorder?index=0

@GET(“takeorder?index=0”)

fun getOrderList() : Call

}

var goodsInfos: List? = null

var distribution: Distribution? = null

var detail: OrderDetail? = null

inner class Rider {

var id = 0

var name: String? = null

var phone: String? = null // public Location location;

}

inner class OrderDetail {

var username: String? = null

var phone: String? = null

var address: String? = null

var pay: String? = null

var time: String? = null

}

inner class Distribution {
