Android解析JSON格式数据的两种方式(JSONObject和Gson)

  [{"id":"1","verison":"1.0","name":"shufu"},
         {"id":"2","verison":"2.2","name":"pangzi"},
         {"id":"3","verison":"3.3","name":"john"}]

private fun parserJSONWithJSONObject(jsonData: String) {
        try {
            val jsonArray = JSONArray(jsonData)
            for (i in 0 until jsonArray.length()) {
                val jsonObject = jsonArray.getJSONObject(i)
                val id = jsonObject.getString("id")
                val name = jsonObject.getString("name")
                val version = jsonObject.getString("version")
                Log.d("MainActivity", "id is $id")
                Log.d("MainActivity", "name is $name")
                Log.d("MainActivity", "version is $version")
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

   implementation 'com.google.code.gson:gson:2.8.6'

  {"name":"John","age":18}

　val gson = Gson()
  val person = gson.fromJson(jsonData, Person::class.java)

  [{"name":"John","age":18},
         {"name":"Jack","age":19}, 
         {"name":"shufu","age":20}]

 val typeOf = object : TypeToken<List<Person>>() {}.type
 val people = gson.fromJson<List<Person>>(jsonData, typeOf)

class App(val id: String, val name: String, val version: String)

　private fun parseJSONWithGSON(jsonData: String) {
    val gson = Gson()
    val typeOf = object : TypeToken<List<App>>() {}.type
    val appList = gson.fromJson<List<App>>(jsonData,typeOf)
    for (app in appList) {
        Log.d("MainActivity", "id is ${app.id}")
        Log.d("MainActivity", "name is ${app.name}")
        Log.d("MainActivity", "version is ${app.version}")
    }
