我在学校课程中将这些数据解析为：
JsonArrayRequest schoolRequest = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
OurSchool ourSchool = new OurSchool();
ourSchool.schoolId = obj.getInt("id");
ourSchool.schoolName = obj.getString("name");
ourSchool.schoolLocation = obj.getString("address");
ourSchool.schoolLogo = obj.getString("logo");
ourSchool.district=obj.getString("district");
ourSchool.country=obj.getString("country");
ourSchool.phone=obj.getString("phone");
ourSchool.email=obj.getString("email");
ourSchool.website=obj.getString("website");
ourSchool.type=obj.getString("institution_type");
ourSchool.estb_date=obj.getString("establishment_date");
ourSchool.admission_start_date=obj.getString("admission_open_from");
ourSchool.admission_end_date=obj.getString("admission_open_to");
ourSchool.latitude=obj.getDouble("latitude");
ourSchool.longitude=obj.getDouble("longitude");
// adding schools to ourSchool list
JSONArray fees=obj.getJSONArray("fees");
List<FeeClass> listFeeClass= new ArrayList<FeeClass>();//by Ahamed
for (int j=0;j<fees.length(); j++){
FeeClass feeClass= new FeeClass();//by Ahamed
JSONObject obj1=fees.getJSONObject(j);
feeClass.setGrade(obj1.getString("grade"));//By Ahamed
feeClass.setFee(obj1.getString("price"));//ByAhamed
listFeeClass.add(feeClass);//by Ahamed
ourSchool.grade=obj1.getString("grade");//you need to remove this line
ourSchool.fee=obj1.getString("price");//you need to remove this line
}
ourSchool.setFeesList(listFeeClass);//by Ahamed
ourSchoolsListItems.add(ourSchool);
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
});
我将这些数据发送到我的schooldetail课程
Intent i = new Intent(School.this, SchoolDetails.class);
i.putExtra("school", ourSchoolsListItems.get(position));
startActivity(i);
最后我尝试将相应学校的所有这些数据检索为
ourSchool = (OurSchool) getActivity().getIntent().getSerializableExtra("school");
一切都很好。唯一的问题是内部＆＃34;费用＆＃34; api中的对象。我想显示相应课程的所有费用细节。但我只是收到最后一个对象的费用细节＆＃34;费用＆＃34;。例如在小天使的学费范围内，我只是获得2级的成绩，等级和价格。我想检索费用数组中的所有对象详细信息。请帮助。
更新 //由艾哈迈德
class FeeClass{
String grade,fee;
public void setGrade(String grade){
this.grade=grade;
}
public String getGrade(){
return this.grade;
}
}
在OurSchool课程中添加以下变量。
List<FeeClass> feeClassObject= new ArrayList<FeeClass>();
还有getter和setter
public void setFeesList(List<FeeClass> feeClassObject){
this.feeClassObject=feeClassObject;
}
public List<FeeClass> getFeesList(){
return feeClassObject;
}
并查看您的for循环代码
答案 0 :(得分：1)
因为，你的第一个循环学校创建了一个单独的OurSchool对象。在单个的ourchool对象中，您试图将所有费用详细信息放在单个指针对象中。因此，第一个费用详细信息保存在该费用详细信息对象上，并再次收取第二个费用详细信同样的事情，直到你的第二个循环完成。所以，最后一项只存在于该对象上。就这样。快乐的编码。
修改
因此，您必须在ourSchool对象上维护一个List。
像，
class FeeObject{
String feeDetails1,feeDetails2..etc
}
在OurSchoolObject中添加以下变量。
List<FeeObject> feeObjectList= new ArrayList<>();
这就是全部

使用此模型类来解析json。
public class OurSchool {
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getDistrict() {
return district;
}
public void setDistrict(String district) {
this.district = district;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {

public String getInstitutionType() {

}
public void setInstitutionType(String institutionType) {
this.institutionType = institutionType;
}
public String getEstablishmentDate() {
return establishmentDate;
}
public void setEstablishmentDate(String establishmentDate) {
this.establishmentDate = establishmentDate;
}
public String getAdmissionOpenFrom() {
return admissionOpenFrom;
}
public void setAdmissionOpenFrom(String admissionOpenFrom) {
this.admissionOpenFrom = admissionOpenFrom;
}
public String getAdmissionOpenTo() {
return admissionOpenTo;
}
public void setAdmissionOpenTo(String admissionOpenTo) {
this.admissionOpenTo = admissionOpenTo;
}
public String getLogo() {
return logo;
}
public void setLogo(String logo) {
this.logo = logo;
}
public int getActive() {
return active;
}
public void setActive(int active) {
this.active = active;
}
public String getCreatedAt() {
return createdAt;
}
public void setCreatedAt(String createdAt) {
this.createdAt = createdAt;
}
public String getUpdatedAt() {
return updatedAt;
}
public void setUpdatedAt(String updatedAt) {
this.updatedAt = updatedAt;
}
public double getLatitude() {
return latitude;
}
public void setLatitude(double latitude) {
this.latitude = latitude;
}
public double getLongitude() {
return longitude;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
public List<Fees> getFees() {
return fees;
}
public void setFees(List<Fees> fees) {
this.fees = fees;
}

然后添加依赖项
compile 'com.google.code.gson:gson:2.8.0'
答案 2 :(得分：0)
请在下面这样做。如果有任何混淆，请告诉我。
public class OurSchool {
private ArrayList<Fees> feeList;
public void setFees(ArrayList<Fees> list){
this.feeList=list
}
publice ArrayList<Fees> getFeeList(){
return feeList;
}
}
public class Fees{
private long id;
private long school_id;
private int grade;
private int fee;
}
然后OnResonse方法就是这样的
JsonArrayRequest schoolRequest = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
-------other code -------
JSONArray fees=obj.getJSONArray("fees");
ArrayList<Fees> feeList=new ArrayList<Fees>;
for (int j=0;j<fees.length(); j++){
final Fees fees=new Fees();
JSONObject obj1=fees.getJSONObject(j);
fees.grade=obj1.getString("grade");
fees.fee=obj1.getString("price");
feeList.add(fees)
}
ourSchool.setFees(feeList); /// Add the feeList ///
ourSchoolsListItems.add(ourSchool);// Add the OurSchool ///
}
