我陷入一个循环状态，我在另一个循环中使用for循环，以便在我从Json响应中获取的嵌套recyclerview中显示数据，但没有得到所需的解决方案，下面是我的代码，我也正在附加我的结果输出并附加了必需的输出，如果有人知道解决方案，请帮助我。
我的代码在这里
JSONArray jsonArray = jsonRootObject.getJSONArray("data");
for(int i=0;i < jsonArray.length();i++){
JSONObject object1 =jsonArray.getJSONObject(i);
JSONArray jsonArrayRates = object1.getJSONArray("rates");
Log.e("jsonArraySize",String.valueOf(jsonArrayRates.length()));
String fuel_type = null;
demoCarSectionList.clear();
for (int j=0;j < jsonArrayRates.length();j++){
JSONObject objectRates=jsonArrayRates.getJSONObject(j);
access_Rate=objectRates.getString("access_rate");
String carID=objectRates.getString("car_id");
Log.e( "carIdInside" ,carID);
amount= (rate_int * time_int);
freeDriving= String.valueOf(distance_Car);
demoCarSectionList.add(access_Rate);
}
Log.e( "value_inside" , demoCarSectionList.get(1));
demoCarList.add((ArrayList<String>) demoCarSectionList);
}
Resulted output from above code-

答案 0 :(得分：0)
经过2-3天的努力后，我得到了答案，这都与列表的初始化有关，它的很小的错误，demoCarSectionList需要在本地初始化，因此它将为循环的每个索引更新列表。
代码应该像这样
JSONArray jsonArray = jsonRootObject.getJSONArray("data");
for(int i=0;i < jsonArray.length();i++){
JSONObject object1 =jsonArray.getJSONObject(i);
JSONArray jsonArrayRates = object1.getJSONArray("rates");
Log.e("jsonArraySize",String.valueOf(jsonArrayRates.length()));
String fuel_type = null;
demoCarSectionList= new ArrayList<>();
demoCarSectionList.clear();
for (int j=0;j < jsonArrayRates.length();j++){
JSONObject objectRates=jsonArrayRates.getJSONObject(j);
access_Rate=objectRates.getString("access_rate");
String carID=objectRates.getString("car_id");
Log.e( "carIdInside" ,carID);
amount= (rate_int * time_int);
freeDriving= String.valueOf(distance_Car);
demoCarSectionList.add(access_Rate);
}
Log.e( "value_inside" , demoCarSectionList.get(1));
demoCarList.add((ArrayList<String>) demoCarSectionList);
}
