how to display data of different api ids to different items of recycle view?

Question

I will briefly write what I exactly want and where I'm exactly stucked.I'm loading a list in recycleview from api using retrofit(which I have loaded successfully)see this image-->image description here.

Further I have two api ids(example :https//..id=1 and https//..id=2 and so on depending upon this list image description here.)

here is my 2 apis:(first one https//..id=1)

{"id":"1","title":"Android Introduction","description":"
Android is a Linux based operating system it is designed primarily for touch screen mobile devices such as smart phones and tablet computers. The operating system have developed a lot in last 15 years starting from black and white phones to recent smart phones or mini computers.

second one:(https//..id=2)

As you can see from apis that on click on items should load their respective description from apis to next activity like this-->image description here

if you want I can share code.just tell what exactly you need .I will edit

here is my code for nextactivity adapter:

public class NextAndroidAdapter  extends RecyclerView.Adapter<NextAndroidAdapter.CustomViewHolder> {
DescriptionModel WAmdel;
Context context;
public NextAndroidAdapter(Context context,DescriptionModel employees) {
    this.WAmdel = employees;
    this.context=context;
}



@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.nextwhatsandroid_item , parent, false);

    return new CustomViewHolder(itemView);
}

@Override
public void onBindViewHolder(CustomViewHolder holder, final int position) {

  // holder.textView.setText(String.valueOf(position+1)+". ");
   holder.textView.setText(WAmdel.getDescription());

}

@Override
public int getItemCount() {
    return 1;
}

public class CustomViewHolder extends RecyclerView.ViewHolder {
    TextView textView;

    public CustomViewHolder(View view) {
        super(view);
       // employeeName = (TextView) view.findViewById(R.id.WA2);
        textView=view.findViewById(R.id.detailswhatsandroid);
        
            }
        });

    }
}

}

this is my recycle view items adapter(of image description here):

public class WhatsAndroidAdapter extends RecyclerView.Adapter<WhatsAndroidAdapter.CustomViewHolder> {
List<WhatsAndroid.WhatsAndroidModel> WAmdel;
Context context;
public WhatsAndroidAdapter(Context context,List<WhatsAndroid.WhatsAndroidModel> employees) {
    this.WAmdel = employees;
    this.context=context;
}



@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.whatsandroid_item , parent, false);

    return new CustomViewHolder(itemView);
}

@Override
public void onBindViewHolder(CustomViewHolder holder, final int position) {

    holder.textView.setText(String.valueOf(position+1)+". ");
    holder.employeeName.setText(WAmdel.get(position).getTitle());

}

@Override
public int getItemCount() {
    return WAmdel.size();
}

public class CustomViewHolder extends RecyclerView.ViewHolder {
    public TextView employeeName;
    TextView textView;

    public CustomViewHolder(View view) {
        super(view);
        employeeName = (TextView) view.findViewById(R.id.WA2);
        textView=view.findViewById(R.id.WA1);
      view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent =  new Intent(context, NextActivity.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intent.putExtra("title", WAmdel.get(getAdapterPosition()).getTitle());

                context.startActivity(intent);

            }
        });

    }
}

}

next activity:

public class NextActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private NextAndroidAdapter adapter;
private DescriptionModel DescriptList;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.nextwhatsandroid_layout);
    Toolbar toolbar = (Toolbar) findViewById(R.id. toolbar );
    setSupportActionBar( toolbar );
    if (getSupportActionBar() != null) {
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
    }
    Intent intent = getIntent();
    String title = intent.getStringExtra("title");
  String hello=intent.getStringExtra("hii");

    getSupportActionBar().setTitle(title);
    /*Create handle for the RetrofitInstance interface*/
    DescriptService service = DescriptClientInstance.getRetrofitInstance().create(DescriptService.class);
    Call<DescriptionModel> call = service.getAllPhotos();
    call.enqueue(new Callback<DescriptionModel>() {
        @Override
        public void onResponse(Call<DescriptionModel> call, Response<DescriptionModel> response) {
           // progressDialog.dismiss();
            DescriptList=response.body();
            generateDataList(DescriptList);
        }

        @Override
        public void onFailure(Call<DescriptionModel> call, Throwable t) {
           // progressDialog.dismiss();

            Toast.makeText(getApplicationContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
        }
    });
}
private void generateDataList(DescriptionModel photoList) {
    recyclerView = findViewById(R.id.recyclenext);
    LinearLayoutManager manager = new LinearLayoutManager(getApplicationContext());
    recyclerView.setLayoutManager(manager);
    recyclerView.setHasFixedSize(true);
    adapter = new NextAndroidAdapter(getApplicationContext(),photoList);
    recyclerView.setAdapter(adapter);
}
@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    if (item.getItemId() ==android.R.id.home) {
        finish();
    }
    return super.onOptionsItemSelected(item);
}
@Override
public void onBackPressed() {
    super.onBackPressed();
}

}

but now im getting out as something like this: when I click on item0 it went to next screen and displays description of item1 but when I click on item1 it went to next screen displays same description as previous..what should I do in interface method of retrofit?

need help...thanks in advance

Please check if `WAmdel` of `WhatsAndroidAdapter` has correct data. — shafayat hossain, Dec 24 '19 at 04:15
here is my interface of retrofit that im passing --> @GET("/v1/android_tutorials/single_tutorial?tutorial_id=1") Call getAllPhotos();..thats why im getting same description in both recycle view item — Wini, Dec 24 '19 at 08:46
Here in `v1/android_tutorials/single_tutorial?tutorial_id=1` you have set `tutorial_id=1`. So it will always fetch data for id=1. That's why you always see data for id=1. You have to fetch data for different Ids. You have to call the api as following: `@GET("/v1/android_tutorials/single_tutorial") Call getAllPhotos(@Query("tutorial_id") int id);` — shafayat hossain, Dec 24 '19 at 09:41
@shafayathossain what changes do I make in adapter(of nextactivity) and activity(nextactivity)?..I added my activity code(next activity) above..please help — Wini, Dec 24 '19 at 11:32

As far I understand what you want to do, according to that I assume that you need following changes:

In WhatsAndroidAdapter

view.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent =  new Intent(context, NextActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.putExtra("title", WAmdel.get(getAdapterPosition()).getTitle());
        intent.putExtra("id", WAmdel.get(getAdapterPosition()).getId());

        context.startActivity(intent);

    }
});

In NextActivity

Intent intent = getIntent();
String title = intent.getStringExtra("title");
String id = intent.getStringExtra("id");
String hello=intent.getStringExtra("hii");

getSupportActionBar().setTitle(title);
/*Create handle for the RetrofitInstance interface*/
DescriptService service = DescriptClientInstance.getRetrofitInstance().create(DescriptService.class);
Call<DescriptionModel> call = service.getAllPhotos(id);
call.enqueue(new Callback<DescriptionModel>() {
    @Override
    public void onResponse(Call<DescriptionModel> call, Response<DescriptionModel> response) {
       // progressDialog.dismiss();
        DescriptList=response.body();
        generateDataList(DescriptList);
    }

    @Override
    public void onFailure(Call<DescriptionModel> call, Throwable t) {
       // progressDialog.dismiss();

        Toast.makeText(getApplicationContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
    }
});

In DescriptService

@GET("/v1/android_tutorials/single_tutorial") 
Call<DescriptionModel> getAllPhotos(@Query("tutorial_id") String id);

Int id = intent.getIntExtra("id");...this line asking a default value...so when I put 1 as default value then in both items displays same description..what should I do in default value? – Wini Dec 24 '19 at 12:03

Please check if `WAmdel.get(getAdapterPosition()).getId()` returns any valid id of type `int`? – shafayat hossain Dec 24 '19 at 12:44
I have a put a log in **WhatsAndroidAdapter**under intent.putExtra("id", WAmdel.get(getAdapterPosition()).getId()); when run and click item got item id in log......but when I put log in **NextActivity** under Int id = intent.getIntExtra("id"); got 1 in logcat – Wini Dec 24 '19 at 12:45
WAmdel.get(getAdapterPosition()).getId()---->got item id in logcat – Wini Dec 24 '19 at 12:46
Int id = intent.getIntExtra("id"); got 1 in logcat – Wini Dec 24 '19 at 12:46

Is it's type `int`? – shafayat hossain Dec 24 '19 at 12:47
yes...I have put int -->Int id = intent.getIntExtra("id"); – Wini Dec 24 '19 at 12:48

according to your post `id` is a `String`, please change it to `String`. – shafayat hossain Dec 24 '19 at 12:50

I've updated my answer. Change your `id` to `String` in `DescriptionModel`. – shafayat hossain Dec 24 '19 at 12:51

I've changed my answer. It'll be `String id = intent.getStringExtra("id");` – shafayat hossain Dec 24 '19 at 12:54
if you don't mind can I ask you more doubts later?? – Wini Dec 24 '19 at 12:56
Sure. I'll try my best to answer. – shafayat hossain Dec 24 '19 at 12:59

in Adapter, onBinding method add item click listner and send description on position base and pass description in intent or throught paramerts like this:

holder.itemView.setonClickListener(new OnItemClickListner{

      override
      onClick(View view){
           intent i=new Intent(context,YOUR_ACTIVITY);
           i.putString("description",you_data_list.get(postion)
           .getString("description");
           context.startActivity(i);
     }
}
