我在学校类里面将这些数据解析为:
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 类中作为
Intent i = new Intent(School.this, SchoolDetails.class);
i.putExtra("school", ourSchoolsListItems.get(position));
startActivity(i);
最后我尝试检索相应学校的所有这些数据
ourSchool = (OurSchool) getActivity().getIntent().getSerializableExtra("school");
一切正常。唯一的问题是 api 中的“费用”对象。我想显示相应类(class)的所有费用明细。但我只是在“费用”中获取最后一个对象的费用详细信息。例如在小天使的学费数组中，我只是获取 2 年级的 ID、年级和价格。我想检索费用数组中的所有对象详细信息。请帮忙。
更新 //通过艾哈迈德
class FeeClass{
String grade,fee;
public void setGrade(String grade){
this.grade=grade;
}
public String getGrade(){
return this.grade;
}
}
在您的 OurSchool 类中添加以下变量。
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;
}
然后查看您的 for 循环代码
最佳答案
因为，您的第一个 for 循环学校创建了一个 OurSchool 对象。在那个单一的 ourschool 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，第一个费用明细保存在该费用明细对象中，第二个费用明细再次替换您现有的费用明细对象。在你的第二个 for 循环完成之前做同样的事情。因此，最后一项只会存在于该对象上。就这样。快乐编码。
编辑
因此，您必须在我们的学校对象上维护一个列表。
喜欢，
class FeeObject{
String feeDetails1,feeDetails2..etc
}
在 OurSchoolObject 中添加以下变量。
List<FeeObject> feeObjectList= new ArrayList<>();
就这样
