I wanted to setup a list of users and their corresponding details by fetching data from https://jsonplaceholder.typicode.com/users. But I cannot add multiple objects.
I was able to show 6 details such as id, name, username, email, phone and website. But somehow when I'm integrating "address" as a new JSONObject under JsonArrayRequest, I'm getting a blank screen on my emulator.
Here's what I did:
JsonArrayRequest jar =new JsonArrayRequest(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
for(int i=0; i<response.length(); i++) {
try {
JSONObject JSobj1 = response.getJSONObject(i); //First object
String id = JSobj1.getString("id");
String name = JSobj1.getString("name");
String username = JSobj1.getString("username");
String email = JSobj1.getString("email");
String phone =JSobj1.getString("phone");
String website =JSobj1.getString("website");
JSONObject JSobj2 = JSobj1.getJSONObject("address"); //Second object
String street = JSobj2.getString("street");
String suite = JSobj2.getString("suite");
String city = JSObj2.getString("city");
String zipcode = JSObj2.getString("zipcode");
Setget sg =new Setget();
sg.setId(id);
sg.setName(name);
sg.setUsername(username);
sg.setEmail(email);
sg.setPhone(phone);
sg.setWebsite(website);
sg.setStreet(street);
sg.setSuite(suite);
sg.setCity(city);
sg.setZipcode(zipcode);
arrayList.add(sg);
if(arrayList.size()>0){
listView.setAdapter(new Myadapter()); //Custom Adapter
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this,"Server Error",Toast.LENGTH_SHORT).show();
}
});
Volley.newRequestQueue(MainActivity.this).add(jar);
}
I expected the full list from https://jsonplaceholder.typicode.com/users as an output but there's a blank screen on my emulator. Please help.
Thanks
Hey you need add below classes
public class Address {
@SerializedName("street")
@Expose
private String street;
@SerializedName("suite")
@Expose
private String suite;
@SerializedName("city")
@Expose
private String city;
@SerializedName("zipcode")
@Expose
private String zipcode;
@SerializedName("geo")
@Expose
private Geo geo;
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getSuite() {
return suite;
}
public void setSuite(String suite) {
this.suite = suite;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getZipcode() {
return zipcode;
}
public void setZipcode(String zipcode) {
this.zipcode = zipcode;
}
public Geo getGeo() {
return geo;
}
public void setGeo(Geo geo) {
this.geo = geo;
}
}
Company Class

return name;
}
public void setName(String name) {
this.name = name;
}
public String getCatchPhrase() {
return catchPhrase;
}
public void setCatchPhrase(String catchPhrase) {
this.catchPhrase = catchPhrase;
}
public String getBs() {
return bs;
}
public void setBs(String bs) {
this.bs = bs;
}
}

Replace below code with your code
@Note: Replace mJsonArray with your response class
ArrayList<TestModel> listdata = new ArrayList<TestModel>();
JSONArray mJsonArray = new JSONArray();
//Replace mJsonArray to response
for(int i=0; i<mJsonArray.length(); i++) {
try {
JSONObject json = mJsonArray.getJSONObject(i); //First object
String id = json.getString("id");
String name = json.getString("name");
String username = json.getString("username");
String email = json.getString("email");
String phone =json.getString("phone");
String website =json.getString("website");
JSONObject json2 = json.getJSONObject("address"); //Second object
String street = json2.getString("street");
String suite = json2.getString("suite");
String city = json2.getString("city");
String zipcode = json2.getString("zipcode");
JSONObject json3 = json2.getJSONObject("geo");
String lat = json3.getString("lat");
String lang = json3.getString("lng");
JSONObject json4 = json.getJSONObject("company");
String companyName = json4.getString("name");
String catchPhrase = json4.getString("catchPhrase");
String bs = json4.getString("bs");
TestModel model = new TestModel();
model.setId(id);
model.setName(name);
model.setUsername(username);
model.setEmail(email);
model.setPhone(phone);
model.setWebsite(website);
Address mAddress = new Address();
mAddress.setStreet(street);
mAddress.setSuite(suite);
mAddress.setCity(city);
mAddress.setZipcode(zipcode);
Geo mGeo = new Geo();
mGeo.setLat(lat);
mGeo.setLng(lang);
mAddress.setGeo(mGeo);
model.setAddress(mAddress);
Company company = new Company();
company.setBs(bs);
company.setCatchPhrase(catchPhrase);
company.setName(companyName);
model.setCompany(company);
listdata.add(model);
} catch (JSONException e) {
e.printStackTrace();
}
}
if(listdata.size()>0){
//Hope you need pass list to MyAdapter
listView.setAdapter(new Myadapter()); //Custom Adapter
}
