这是一个 API 的 URL...我如何解析这个对象以使用改造来获取数据？

这里是关于如何使用改造来获取带有数组的 JSON 对象的示例。我相信您在更改它以处理您的数据时不会遇到麻烦。

Example.java

public class Example {

@SerializedName("PnrNumber")
@Expose
private String pnrNumber;
@SerializedName("Status")
@Expose
private String status;
@SerializedName("ResponseCode")
@Expose
private String responseCode;
@SerializedName("TrainNumber")
@Expose
private String trainNumber;
@SerializedName("TrainName")
@Expose
private String trainName;
@SerializedName("JourneyClass")
@Expose
private String journeyClass;
@SerializedName("ChatPrepared")
@Expose
private String chatPrepared;
@SerializedName("From")
@Expose
private String from;
@SerializedName("To")
@Expose
private String to;
@SerializedName("JourneyDate")
@Expose
private String journeyDate;
@SerializedName("Passangers")
@Expose
private List<Passanger> passangers = null;

public String getPnrNumber() {
return pnrNumber;
}

public void setPnrNumber(String pnrNumber) {
this.pnrNumber = pnrNumber;
}

public String getStatus() {
return status;
}

public void setStatus(String status) {
this.status = status;
}

public String getResponseCode() {
return responseCode;
}

public void setResponseCode(String responseCode) {
this.responseCode = responseCode;
}

public String getTrainNumber() {
return trainNumber;
}

public void setTrainNumber(String trainNumber) {
this.trainNumber = trainNumber;
}

public String getTrainName() {
return trainName;
}

public void setTrainName(String trainName) {
this.trainName = trainName;
}

public String getJourneyClass() {
return journeyClass;
}

public void setJourneyClass(String journeyClass) {
this.journeyClass = journeyClass;
}

public String getChatPrepared() {
return chatPrepared;
}

public void setChatPrepared(String chatPrepared) {
this.chatPrepared = chatPrepared;
}

public String getFrom() {
return from;
}

public void setFrom(String from) {
this.from = from;
}

public String getTo() {
return to;
}

public void setTo(String to) {
this.to = to;
}

public String getJourneyDate() {
return journeyDate;
}

public void setJourneyDate(String journeyDate) {
this.journeyDate = journeyDate;
}

public List<Passanger> getPassangers() {
return passangers;
}

public void setPassangers(List<Passanger> passangers) {
this.passangers = passangers;
}

}

Passanger.Java

public class Passanger {

@SerializedName("Passenger")
@Expose
private String passenger;
@SerializedName("BookingStatus")
@Expose
private String bookingStatus;
@SerializedName("CurrentStatus")
@Expose
private String currentStatus;

public String getPassenger() {
return passenger;
}

public void setPassenger(String passenger) {
this.passenger = passenger;
}

public String getBookingStatus() {
return bookingStatus;
}

public void setBookingStatus(String bookingStatus) {
this.bookingStatus = bookingStatus;
}

public String getCurrentStatus() {
return currentStatus;
}

public void setCurrentStatus(String currentStatus) {
this.currentStatus = currentStatus;
}

}

以下是根据您在问题中提供的响应生成的类。 您可以使用此链接为 JSON 响应生成 POJO 类。 JSON TO POJO

添加这个 gradle：

implementation 'com.google.code.gson:gson:2.8.2'

初始化 Gson 构建器：

private Gson gson;


GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.setDateFormat("M/d/yy hh:mm a");
gson = gsonBuilder.create();

使用 GSON 解析 JSON

gson.fromJson(jsonObject.getJSONObject("data").toString(), Example.class);

这些是使用 GSON 解析 JSON 的基本步骤。
