如何使用 Kotlin 转换 Android Studio 中字符串列表中的 StringBuilder 项?
How can I convert a StringBuilder item in a List of strings in Android Studio using Kotlin?
我的改造中有这个 StringBuilder 项目:
retrofitData.enqueue(object:Callback<List<HospitalResponse>?>{
override fun onResponse(call: Call<List<HospitalResponse>?>, response: Response<List<HospitalResponse>?>) {
val responseData = response.body()!!
val myStringBuilder = StringBuilder()
for(hospitalResponse in responseData){
myStringBuilder.append(hospitalResponse.hospitalName)
myStringBuilder.append("\n")
}
我想将 StringBuilder 转换为列表:
val hospitals = mutableListOf<String>()
我该怎么做?
我看到三个选项:
- 获取 StringBuilder 并将其转换为列表(不推荐)
val list1 = myStringBuilder.toString().trim('\n').split("\n")
- 创建一个列表并将名称放入列表而不是将其附加到 StringBuilder
val list2 = ArrayList<String>()
for(hospitalResponse in responseData){
list2.add(hospitalResponse.hospitalName)
}
- 使用折叠功能
val list3 = responseData.fold(ArrayList<String>()) { list, value ->
list.add(value.hospitalName)
list
}
