this link可以帮助我们，
好，
1。我们的模型类可能像：
public class SlotInfo {
public String dateOfSlot;
public ArrayList<AvailableTimeSlot> availableTimeSlots;
public long scheduleId;
public ArrayList<GetBlockedTiming> getBlockedTimings;
public long blockId;
public long fkTimeId;
public boolean isDeleted;
public long fkScheduledId;
public long utcDateOfSlot;
}
public class AvailableTimeSlot {
public long timeSlotId;
public String timeOfSlot;
public String timeofSlotDateTime;
}
public class GetBlockedTiming {
public String dateOfSlot;
public ArrayList<AvailableTimeSlot> availableTimeSlots;
public ArrayList<GetBlockedTiming> getBlockedTimings;
public long blockId;
public long fkTimeId;
public boolean isDeleted;
public long fkScheduledId;
public long utcDateOfSlot;
}
我们应该
ArrayList<SlotInfo> slotInfos = new ArrayList<>();
try {
JSONObject jSlots = new JSONObject("Your JSON String");
JSONArray arrDetail = jSlots.getJSONArray("Detail");
for(int i = 0; i < arrDetail.length(); i++) {
JSONObject jSlot = arrDetail.getJSONObject(i);
SlotInfo slotInfo = new SlotInfo();
slotInfo.blockId = jSlot.getLong("blockId");
slotInfo.dateOfSlot = jSlot.getString("dateOfSlot");
slotInfo.fkScheduledId = jSlot.getLong("fkScheduledId");
slotInfo.fkTimeId = jSlot.getLong("fkTimeId");
// so set all top level data ...
// then availableTimeSlots
slotInfo.availableTimeSlots = new ArrayList<>();
JSONArray arrAvailableTimeSlots = jSlots.getJSONArray("AvailableTimeSlots");
for(int j = 0; j < arrAvailableTimeSlots.length(); j++) {
JSONObject jAvailableTimeSlot = arrAvailableTimeSlots.getJSONObject(j);
AvailableTimeSlot availableTimeSlot = new AvailableTimeSlot();
availableTimeSlot.timeOfSlot = jAvailableTimeSlot.getString("timeOfSlot");
// so set all data ...
// and add it to
slotInfo.availableTimeSlots.add(availableTimeSlot);
}
// then GetBlockedTimings
slotInfo.getBlockedTimings = new ArrayList<>();
JSONArray arrGetBlockedTimings = jSlots.getJSONArray("GetBlockedTimings");
for(int k = 0; k < arrGetBlockedTimings.length(); k++) {
JSONObject jGetBlockedTiming = arrAvailableTimeSlots.getJSONObject(k);
GetBlockedTiming getBlockedTiming = new GetBlockedTiming();
getBlockedTiming.blockId = jGetBlockedTiming.getLong("blockId");
// so set all data ...
// and add it to
slotInfo.getBlockedTimings.add(getBlockedTiming);
}
slotInfos.add(slotInfo);
}
} catch (JSONException e) {
e.printStackTrace();
}
假设我们在类级别定义文本视图：
TextView tvDateOfSlot1;
TextView tvDateOfSlot2;
TextView tvDateOfSlot3;
所以我们可以在onCreateView中设置它们，例如：
tvDateOfSlot1 = findViewById(R.id.tv_dateOfSlot1);
tvDateOfSlot2 = findViewById(R.id.tv_dateOfSlot2);
tvDateOfSlot3 = findViewById(R.id.tv_dateOfSlot3);
然后，在初始化“ slotInfos”后，我们可以设置textView值，例如：
tvDateOfSlot1.setText(slotInfos[0].dateOfSlot);
tvDateOfSlot2.setText(slotInfos[1].dateOfSlot);
tvDateOfSlot3.setText(slotInfos[2].dateOfSlot);
祝你好运

答案 1 :(得分：0)
JsonObject mainObject = new JsonObject("Your JSON String");
JsonArray arr = mainObject.getJsonArray("Detail");
for(int i = 0; i < arr.lenght(); i++) {
JsonObject dateOfSlotObj = arr.getJsonObject(i);
String dateOfSlot = dateOfSlotObj.getString("DateOfSlot");//DateOfSlot field
JsonArray availableSlotsArr = dateOfSlotObj.getJsonArray("AvailableTimeSlots");
for(int j = 0; j < availableSlotsArr.lenght(); j++) {
JsonObject availableSlotObj = availableSlotsArr[j];
int timeSlotId = availableSlotObj.getInt("TimeSlotId");
String timeOfSlot= availableSlotObj.getString("TimeOfSlot");
String timeofSlotDateTime= availableSlotObj.getString("TimeofSlotDateTime");
}
}
要检查GetBlockedTimings是否不为空，可以检查下一行代码
if(!dateOfSlotObj.isNull("GetBlockedTimings")){
//extract array and do something
}
