Android 如何将.txtassets资源 转换为ArrayList<；字符串>；kotlin格式

创建一个如下所示的模型

data class Coordinate(val latitude: String, val longitude: String)

//从资源文件中读取坐标并转换为ArrayList的函数

fun readCoordinatesFromAsset(context: Context, assetFileName: String): 
   ArrayList<String> {
   val gson = Gson()
   val arrayList = ArrayList<String>()

   try {
        context.assets.open(assetFileName).use { inputStream ->
        val reader = InputStreamReader(inputStream)
        val coordinates = gson.fromJson(reader, ArrayList::class.java)

        // Convert the ArrayList of Coordinate objects to an ArrayList of strings
        for (coordinate in coordinates) {
            arrayList.add(coordinate.toString())
        }
    }
  } catch (e: Exception) {
    e.printStackTrace()
  }

return arrayList
}

您的文本文件应类似于以下格式

Coordinate.txt

[
        "97.951476367000055,3.155017079000061",
        "97.951800004000063,3.154406602000051",
        "97.949325673000033,3.156145963000029",
        "97.948721732000081,3.15657051200003",
        "97.948646156000052,3.156623638000042",
        "97.947494978000066,3.15786896100002",
        "97.94724135000007,3.158143331000076",
        "97.947000011000057,3.158404405000056",
        "97.946790649000036,3.158630887000072",
        "97.946272953000062,3.15919092200005",
        "97.945702608000033,3.15980791000004",
        "97.945553326000038,3.159969400000023",
        "97.944601930000033,3.160998592000055",
        "97.944409762000078,3.161206474000039"
    ]

您可以将该方法调用为

val resulArray: ArrayList<String> =readCoordinatesFromAsset(this,"Coordinate.txt")
