依赖库

我这里用了应用更新，所以更新的时候需要网络，其他数据读取本地json数据不需要联网

本地json数据加载与解析

import android.content.Context

import java.io.BufferedReader
import java.io.IOException
import java.io.InputStreamReader

class JsonFileUtil {

    companion object {
        fun loadFile(context: Context, fileName: String): String {
            val stringBuilder = StringBuilder()
            try {
                val inputStream = context.resources.assets.open(fileName)
                val isr = InputStreamReader(inputStream)
                val reader = BufferedReader(isr)
                var jsonLine: String?
                while (reader.readLine().also { jsonLine = it } != null) {
                    stringBuilder.append(jsonLine)
                }
                reader.close()
                isr.close()
                inputStream.close()

            } catch (e: IOException) {
                e.printStackTrace()
                YUtils.hideLoading()
            }
            return stringBuilder.toString()
        }
    }
}

private lateinit var mapBeanList: MutableList<Word>

val str = JsonFileUtil.loadFile(this, "word.json")

val mapBeanListType: Type = object : TypeToken<ArrayList<Word?>?>() {}.type
mapBeanList = Gson().fromJson(str, mapBeanListType)

initAdapter(mapBeanList)

private fun initAdapter(list: MutableList<More>) {
    //设置布局排列方式
    val staggeredGridLayoutManager = StaggeredGridLayoutManager(2, LinearLayoutManager.VERTICAL)
    binding.rv.layoutManager = staggeredGridLayoutManager

    //加载适配器
    moreAdapter = MoreAdapter(this, list)
    binding.rv.adapter = moreAdapter
}
