I am beginner in android Retrofit2 API call.
How to fetch items and set in recycler view .I think am not getting how to set items to the adapter class.
please help me out with this.
I have tried all possible ways to solve but not able to find any solution regarding this.
You have error with your models. They aren't properly configured. Please see this tutorial for a better understanding of retrofit and recyclerview.

I know how to receive arrays when they are this type:
[
{
"username": "luis",
"job": "developer",
"age": 23
}
]
my problem is when I must receive an array with a specific name like this:
{"result":[{"userid":"1","username":"Luis","job":"developer","age":"23"}]}
in this case I must receive the array above with the name "result" using retrofit2. Can anyone please help me I'm new at Retrofit.
This is what I have tried:
MainActivity
apiInterface = ApiClient.getApiClient().create(ApiInterface.class);
Call<List<Workers>> call = apiInterface.getWorkers();
call.enqueue(new Callback<List<Workers>>() {
#Override
public void onResponse(Call<List<Workers>> call, Response<List<Workers>> response) {
list=response.body();
adapter = new WorkerAdapter(getApplicationContext(),list);
recyclerView.setAdapter(adapter);
}
#Override
public void onFailure(Call<List<Workers>> call, Throwable t) {
}
});
ApiClient:
public class ApiClient {
public static final String BASE_URL="http://192.168.31.206/test1_database/";
public static Retrofit retrofit = null;
public static Retrofit getApiClient(){
if (retrofit==null){
retrofit=new Retrofit.Builder().baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create()).build();
}
return retrofit;
}
}
ApiInterface:
public interface ApiInterface {
#GET("getAllUser.php")
Call<List<Workers>> getWorkers();
}
my POJO or Workers class:
public class Workers {
#SerializedName("username")
String Name;
#SerializedName("job")
String Job;
#SerializedName("age")
int Age;
public String getName() {
return Name;
}
public String getJob() {
return Job;
}
public int getAge() {
return Age;
}
}
and finally my RecyclerAdpter:
public class WorkerAdapter extends RecyclerView.Adapter<WorkerAdapter.ViewHolder>{
Context context;
List<Workers> list;
public WorkerAdapter(Context context,List<Workers> list) {
this.context = context;
this.list = list;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.item_recycler,parent,false);
ViewHolder holder = new ViewHolder(v);
return holder;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.name.setText(list.get(position).getName());
holder.job.setText(list.get(position).getJob());
holder.age.setText(String.valueOf(list.get(position).getAge()));
}
#Override
public int getItemCount() {
return list.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView name, job, age;
public ViewHolder(View itemView) {
super(itemView);
name= (TextView) itemView.findViewById(R.id.nametxt);
job=(TextView) itemView.findViewById(R.id.jobtxt);
age=(TextView) itemView.findViewById(R.id.agetxt);
}
}
}
I've been stuck for two days now and I still can't solve it. Please help!
create a class model called Result and in Interface class write this code:
#GET("your endpoint")
Call<Result>getResult();
and in Result class write below code:
#SerializedName("result")
private List<UserInfo> userInfo;
good luck.
package com.example;
import java.util.List;
public class Example {
private List<Result> result = null;
public List<Result> getResult()
{
return result;
}
public void setResult(List<Result> result)
{
this.result = result;
}}
package com.example;
public class Result {
private String userid;
private String username;
private String job;
private String age;
public String getUserid()
{
return userid;
}
public void setUserid(String userid)
{
this.userid = userid;
}
public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String getJob()
{
return job;
}
public void setJob(String job)
{
this.job = job;
}
public String getAge()
{
return age;
}
public void setAge(String age)
{
this.age = age;
}}
Make some model using this website. I have done these above code using this website.
Now, do this
#Get<"url">
call<Example> get()
if you have to use this json format
{"result":[{"userid":"1","username":"Luis","job":"developer","age":"23"}]}
you have to create two models like this:
class Result {
#SerializedName("result")
#Expose
List<ResultDetail> result;
}
class ResultDetail {
#SerializedName("userid")
#Expose
String userId ;// use int instead
String username;
String job;
String age; // use int instead
}
add GsonConverterFactory to your app build.gradle
com.squareup.retrofit2:converter-gson:2.14
now build retrofit instance :
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("some base url like : www.example.com/api/")
.addConverterFactory(GsonConverterFactory.create())
.build();
YourSerivce service = retrofit.create(YourService.class);
interface YourService {
#GET("someThing") // complete url is www.example.com/api/someThing
Call<Result> getResult();
}
and finally get result like this :
retrofit.getResult().enqueue(.....)
After a lot of testing guided by the 3 answers given and some video tutorial I finally figure it out.
ApiClient:
public class ApiClient {
private static final String BASE_URL="http://192.168.31.206/";
public static Retrofit retrofit = null;
public static ApiInterface instance=null;
public static Retrofit getApiClient(){
if (retrofit==null){
retrofit=new Retrofit.Builder().baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create()).build();
}
return retrofit;
}
public static ApiInterface getInterface(){
if (instance==null){
instance=getApiClient().create(ApiInterface.class);
}
return instance;
}
}
ApiInterface:
public interface ApiInterface {
//this could be test1_database/getAllUser.json
#GET("test1_database/getAllUser.php")
Call<Result> getWorkers();
}
Workers (POJO) class:
public class Workers {
#SerializedName("userid")
private String userid;
#SerializedName("username")
private String username;
#SerializedName("job")
private String job;
#SerializedName("age")
private String age;
public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}
Result (POJO) class:
public class Result {
#SerializedName("result")
private List<Workers> result = null;
public List<Workers> getResult() {
return result;
}
public void setResult(List<Workers> result) {
this.result = result;
}
}
MainActivity class:
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
List<Workers> list = new ArrayList<>();
WorkerAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.recycler);
recyclerView.setHasFixedSize(true);
LinearLayoutManager manager = new LinearLayoutManager(this);
manager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(manager);
ApiInterface apiCall = ApiClient.getInterface();
Call<Result> call = apiCall.getWorkers();
call.enqueue(new Callback<Result>() {
#Override
public void onResponse(Call<Result> call, Response<Result> response) {
list = response.body().getResult();
adapter = new WorkerAdapter(MainActivity.this,list);
recyclerView.setAdapter(adapter);
}
#Override
public void onFailure(Call<Result> call, Throwable t) {
}
});
}}
I am Showing the results in a recyclerview using this adapter:
public class WorkerAdapter extends RecyclerView.Adapter<WorkerAdapter.ViewHolder>{
Context context;
List<Workers> list;
public WorkerAdapter(Context context,List<Workers> list) {
this.context = context;

holder.id.setText(String.valueOf(list.get(position).getUserid()));
holder.name.setText(list.get(position).getUsername());
holder.job.setText(list.get(position).getJob());
holder.age.setText(String.valueOf(list.get(position).getAge()));
}
#Override

I'm pretty new to android and third-party libraries, so I have one problem.
I want to store some data coming from REST API into Realm, then show it into RecyclerView. I have three tabs using the same recyclerView, so it can display three different states.
Here's my classes:
public class RealmContentAdapter extends RealmRecyclerViewAdapter<ContentDataModel, RealmContentAdapter.ViewHolder> {

public static class ViewHolder extends RecyclerView.ViewHolder{

I have some other pojo classes, but this one is the main.

The problem is when I'm trying to save List dataset to Realm, it doesn't save any. And my RealmContentAdapter is empty.
P.S.: I set up GSON carefully and it ignores RealmObject.class
UPD: So, I've found what was wrong. Realm didn't want to save data, because I've missed to add #PrimaryKey to field id in my ContentDataModel. Thank you for attention.
