【问题描述】：

我有一个具有此类定义的数据类

data class AccountInfoResponse(
    @SerializedName("userprofile") val userprofiles: ArrayList<UserProfile>,
    @SerializedName("userpatients") val userpatients: ArrayList<UserPatient>
)

class UserPatient (
    @SerializedName("sex") val sex: String,
    @SerializedName("date of birth") val date_of_birth: String,
    @SerializedName("address") val address: String,
    @SerializedName("patientID") val patientId: Int,
    @SerializedName("first name") val first_name: String,
    @SerializedName("clinicName") val clinic_name: String,
    @SerializedName("clinicID") val clinicId: Int,
    @SerializedName("mobile") val mobile: String,
    @SerializedName("last name") val last_name: String
)

我需要把这个类转换成这样的json字符串

"userpatients":["sex":"male","date of birth":"2010-01-03","image":"","clinics":[1],"primary_provider":["clinic":1,"patient":1,"providers":1],"role":"patient","last name":"John","address":"300 east main st.  San Jose, Ca 95014","first name":"John","username":"John","email":"[e-mail]","mobile":"[phone]"],"userpatients":["sex":"female","date of birth":"2000-01-01","address":"fawal st1","patientID":1,"first name":"john","clinicName":"light house peds","clinicID":1,"mobile":"8056688042","last name":"john"]

【参考方案1】：

我可以看到你想序列化ArrayList<UserPatient>。您可以使用Gson 轻松完成。

例子：

val response = AccountInfoResponse(/* Here goes the objects that is needed to create instance of this class */)

val jsonString = Gson().toJson(response.userpatients)

输出：

"userpatients":["sex":"male","date of birth":"2010-01-03","image":"","clinics":[1],"primary_provider":["clinic":1,"patient":1,"providers":1],"role":"patient","last name":"John","address":"300 east main st.  San Jose, Ca 95014","first name":"John","username":"John","email":"[e-mail]","mobile":"[phone]"],"userpatients":["sex":"female","date of birth":"2000-01-01","address":"fawal st1","patientID":1,"first name":"john","clinicName":"light house peds","clinicID":1,"mobile":"8056688042","last name":"john"]
