Are you using the right model for mapping your response? Should it be:

Set Image array in recyclerview from json data in android

In my app I have got some json data from url. I have deserialize those data in controller class. Now I want to show those image into recyclerview.This recyclerview will be shown in detail activity. I have devided the relative layout into two part. First half is for information and the second half is for a recyclerview. I tried with the follwing code. The problem is I am very new in android developing and I am not getting the correct logic of doing this. I have explained in detail below-
Here is my model class
public class NewsModel {
#Expose
private String id;
#Expose
private String title;
#Expose
private List<AppImage> appImages;
public List<AppImage> getAppImages() {
return appImages;
}
public void setAppImages(List<AppImage> appImages) {
this.appImages = appImages;
}
}
The AppImageClass is
public class AppImage {
#Expose
private String _id;
#Expose
private String alt;
#Expose
private String src;
public String get_id() {
return _id;
}
public void set_id(String _id) {
this._id = _id;
}
public String getAlt() {
return alt;
}
public void setAlt(String alt) {
this.alt = alt;
}
public String getSrc() {
return src;
}
public void setSrc(String src) {
this.src = src;
}
}
The adapter class is
public class NewsImageAdapter extends RecyclerView.Adapter<NewsImageAdapter.ImageHolder> {
private Context context;
private List<NewsModel> imageObject;
public NewsImageAdapter(Context context, List<NewsModel> imageObject) {
this.context = context;
this.imageObject = imageObject;
}
#Override
public ImageHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.newsdetail_image_row,parent,false);
return new ImageHolder(view);
}
#Override
public void onBindViewHolder(ImageHolder holder, int position) {
final NewsModel currentImage=imageObject.get(position);
for (int i = 0; i < currentImage.getAppImages().size() ; i++)
{
AppImage appImage = currentImage.getAppImages().get(i);
Picasso.with(holder.itemView.getContext()).load(appImage.getSrc()).into( holder.images[i] ); }
Picasso.with(holder.itemView.getContext());
}
#Override
public int getItemCount() {
return imageObject.size();
}
public class ImageHolder extends RecyclerView.ViewHolder {
public ImageView images;
public ImageHolder(View itemView) {
super(itemView);
images= itemView.findViewById(R.id.news_image);
}
}
}
In Deatil activity
public class DetailNews extends AppCompatActivity {
private List<NewsModel> newsObject;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.news_detail);
setUpUIViews();
//newsObject=getAllImageList();
}
private void setUpUIViews() {
recyclerView = (RecyclerView)findViewById(R.id.image_list);
recyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(DetailNews.this);
recyclerView.setLayoutManager(layoutManager);
adapter = new NewsImageAdapter(this,newsObject );
recyclerView.setAdapter(adapter);
}
private List<NewsImageModel> getAllImageList() {
//how to set image here?
return images;
}
The json data looks like this
[
{ "id": "5925280ec925a9a6dd5173bb",
"title": "Headline",
"appImages": [
{
"alt": "",
"src": "source1",
"_id": "12213"
},
{
"alt": "",
"src": "source2",
"_id": "fdgdg"
},
{
"alt": "",
"src": "source3",
"_id": "fdfdfdf"
},
{
"alt": "",
"src": "source4",
"_id": "599d9018daf57d002c100ffa"
},
{
"alt": "",
"src": "source5",
"_id": "f7879"
}
],
},
{ "id": "5925280ec925a9a6dd5173bb",
"title": "Headline",
"appImages": [
{
"alt": "",
"src": "source1",
"_id": "12213"
},
{
"alt": "",
"src": "source2",
"_id": "fdgdg"
},
{
"alt": "",
"src": "source3",
"_id": "fdfdfdf"
},
{
"alt": "",
"src": "source4",
"_id": "599d9018daf57d002c100ffa"
},
{
"alt": "",
"src": "source5",
"_id": "f7879"
}
],
},
]

You should use one "raw/item" for each image. You don't need use "Picasso" to load the images, you can use something like:
In your RecyclerView.Adapter
.
.
.
#Override
public void onBindViewHolder(ViewHolderCustom viewHolder, final int position) {
viewHolder.setImage("imageUrl");
}
static class ViewHolderCustom extends RecyclerView.ViewHolder{
private final ImageView imageViewPhotoUrl;
ViewHolderCustom(View v) {
super(v);
imageViewPhotoUrl = (ImageView) v.findViewById(R.id.iv_photo_url);
}
void setImage(String photo) {
if (photo != null && !photo.isEmpty())
new DownloadImageTask(imageViewPhotoUrl)
.execute(photo);
}
}
.
.
.
Your DownloadImageTask:
public class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
private ImageView bmImage;
public DownloadImageTask(ImageView bmImage) {
this.bmImage = bmImage;
}
protected Bitmap doInBackground(String... urls) {
String urlDisplay = urls[0];
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urlDisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
e.printStackTrace();
}
return mIcon11;
}
protected void onPostExecute(Bitmap result) {
if (result != null)
bmImage.setImageBitmap(result);
}
}

Sorry, if it's quite long. I have to show all my code to make it clear. I really need your help guys. Thanks

Set adapter inside onComplete method:
void request(final ProductListRequest productListRequest) {
getApi().loadproductlist(productListRequest.getCode())
.observeOn(AndroidSchedulers.mainThread())
.subscribeOn(Schedulers.io())
.subscribe(new Observer<ProductListResponse>() {
#Override

rvView.setLayoutManager(layoutManager);
adapter = new ProductAdapter(context, list);
rvView.setAdapter(adapter);
}
#Override

}
#Override
public void onNext(ProductListResponse response) {
if (response != null) {
Intent intent = new Intent(ProductActivity.this, ProductList.class);
startActivity(intent);

RecyclerView setting text

I have just jumped to android with a very limited knowledge about recyclerview. I have used a a bit, but faced a situation where setting a text inside onBindViewHolder.Please bear with me.Check the following codes:
1.This is the json, here:
[
{
"restaurantSubscriptionType_Id": 1,
"noOfDaysPlan": "1 Day Trial Meal",
"restaurantSubscriptionEntity": [
{
"restaurantSubscriptionId": 39,
"subscriptionPlan": "Breakfast & Lunch",
"subscriptionImagePath": null,
"subscriptionDays": 1,
"subscriptionAmount": 150,
"restaurant_Subscription_Type_Id": 1
}
],
"restaurantId": 224
},
{
"restaurantSubscriptionType_Id": 2,
"noOfDaysPlan": "5 Days Weekly Plan",
"restaurantSubscriptionEntity": [
{
"restaurantSubscriptionId": 40,
"subscriptionPlan": "Breakfast & Lunch",
"subscriptionImagePath": null,
"subscriptionDays": 5,
"subscriptionAmount": 650,
"restaurant_Subscription_Type_Id": 2
},
{
"restaurantSubscriptionId": 41,
"subscriptionPlan": "Only Lunch",
"subscriptionImagePath": null,
"subscriptionDays": 5,
"subscriptionAmount": 500,
"restaurant_Subscription_Type_Id": 2
}
],
"restaurantId": 224
}
]
I have pojo2schema site
2.RestaurantSubscriptionEntity
public class RestaurantSubscriptionEntity {

private String subscriptionImagePath;
private Integer subscriptionDays;
private Long subscriptionAmount;
private Integer restaurantSubscriptionTypeId;
public RestaurantSubscriptionEntity(){
}
public Integer getRestaurantSubscriptionId() {
return restaurantSubscriptionId;
}
public void setRestaurantSubscriptionId(Integer restaurantSubscriptionId) {
this.restaurantSubscriptionId = restaurantSubscriptionId;
}
public String getSubscriptionPlan() {

}
public void setSubscriptionPlan(String subscriptionPlan) {
this.subscriptionPlan = subscriptionPlan;
}
public String getSubscriptionImagePath() {

public class DemoItemAll {
private Integer restaurantSubscriptionTypeId;
private String noOfDaysPlan;
private List<RestaurantSubscriptionEntity> restaurantSubscriptionEntity = new ArrayList<RestaurantSubscriptionEntity>();
private Long restaurantId;
public DemoItemAll(){
}
public Integer getRestaurantSubscriptionTypeId() {
return restaurantSubscriptionTypeId;
}
public void setRestaurantSubscriptionTypeId(Integer restaurantSubscriptionTypeId) {
this.restaurantSubscriptionTypeId = restaurantSubscriptionTypeId;
}
public String getNoOfDaysPlan() {
return noOfDaysPlan;
}
public void setNoOfDaysPlan(String noOfDaysPlan) {
this.noOfDaysPlan = noOfDaysPlan;
}
public List<RestaurantSubscriptionEntity> getRestaurantSubscriptionEntity() {
return restaurantSubscriptionEntity;
}
public void setRestaurantSubscriptionEntity(List<RestaurantSubscriptionEntity> restaurantSubscriptionEntity) {
this.restaurantSubscriptionEntity = restaurantSubscriptionEntity;
}
public Long getRestaurantId() {
return restaurantId;
}
public void setRestaurantId(Long restaurantId) {
this.restaurantId = restaurantId;
}
4.Here my class which extends RecyclerView
public class DemoAdapter extends RecyclerView.Adapter<DemoAdapter.MyViewHolder> {
private List<DemoItemAll> demoItemAllArrayList = new ArrayList<>();
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public static class MyViewHolder extends RecyclerView.ViewHolder {
private TextView title_tv,price_tv;
private Button drop_down_button;
public MyViewHolder(View itemView) {
super(itemView);
title_tv = (TextView) itemView.findViewById(R.id.day_plan_demo_tv_id);
price_tv = (TextView) itemView.findViewById(R.id.price_demo_tv_id);
drop_down_button = (Button) itemView.findViewById(R.id.demo_drop_down_btn_id);
}
}
public DemoAdapter(List<DemoItemAll> demoItemAllArrayList) {
this.demoItemAllArrayList = demoItemAllArrayList;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.demo_adapter, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
DemoItemAll demoItemAll=new DemoItemAll();
//noOfDays
holder.title_tv.setText(demoItemAll.getNoOfDaysPlan());
}
#Override
public int getItemCount() {
return demoItemAllArrayList.size();
}
}
now here inside onBindView,I need to set this but "subscriptionAmount"
belongs to RestaurantSubscriptionEntity class.How do I access it
holder.price_tv.setText //subscriptionAmount.

You just create new empty DemoItemAll object.
You need to use
DemoItemAll demoItemAll = demoItemAllArrayList.get(position);
instead of
DemoItemAll demoItemAll = new DemoItemAll();

#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
DemoItemAll demoItemAll = demoItemAllArrayList.get(position);
List<RestaurantSubscriptionEntity> entity = demoItemAll.getRestaurantSubscriptionEntity();
holder.title_tv.setText(demoItemAll.getNoOfDaysPlan());
holder.price_tv.setText(String.valueOf(entity.getSubscriptionAmount()))
}

Expected STRING but was BEGIN_ARRAY, Realm and JSON

I have write JSON file:
[
{ "name" : "Sir",
"votes" : 23,
"imageURL" : "http://img.prntscr.com/img?url=http://i.imgur.com/5ogv5yJ.png" },
{ "name" : "Bar",
"votes" : 21,
"imageURL" : [
"http://img.prntscr.com/img?url=http://i.imgur.com/G1qQb9Q.png",
"http://www.dreamhost.com/blog/wp-content/uploads/2015/10/DHC_blog-image-01-300x300.jpg",

"http://www.raspberrypi.org/wp-content/themes/mind-control/images/octocat.jpg"
]
},
{ "name" : "Buildings",
"votes" : 19,
"imageURL" : "http://img.prntscr.com/img?url=http://i.imgur.com/brzudoL.png"}
]
Model class
public class City extends RealmObject {
private String name;
private long votes;
private String imageURL;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public long getVotes() {
return votes;
}
public void setVotes(long votes) {
this.votes = votes;
}
public String getImageURL() {
return imageURL;
}
public void setImageURL(String imageURL) {
this.imageURL = imageURL;
}
}
And Adapter
public class CityAdapter extends BaseAdapter {
//private final Context context;
private LayoutInflater inflater;
private List<City> cities = null;
/* public CityAdapter(Context context) {
this.context = context; */
public CityAdapter(Context context) {
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void setData(List<City> details) {
this.cities = details;
}
#Override
public int getCount() {
if (cities == null) {
return 0;
}
return cities.size();
}
#Override
public Object getItem(int position) {
if (cities == null || cities.get(position) == null) {
return null;
}
return cities.get(position);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(int position, View currentView, ViewGroup parent) {
if (currentView == null) {
currentView = inflater.inflate(R.layout.city_listitem, parent, false);
}
City city = cities.get(position);
ImageView photo = (ImageView) currentView.findViewById(R.id.picture);
if (city != null) {
Picasso.with(inflater.getContext()).load(city.getImageURL()).placeholder(R.drawable.internet_access_placeholder).into(photo);
((TextView) currentView.findViewById(R.id.name)).setText(city.getName());
((TextView) currentView.findViewById(R.id.votes)).setText(String.format(Locale.US, "%d", city.getVotes()));
}
return currentView;
}
}
down there in adapter I setup picasso:
Picasso.with(inflater.getContext()).load(city.getImageURL()).placeholder(R.drawable.internet_access_placeholder).into(photo);
And project is working when I got only one photo in JSON like image from object "name" : "Sir"
But When I write multiple URLs like in 2nd object "name" : "Bar" I get that error: "Expected STRING but was BEGIN_ARRAY"
I understand what is problem but I don't know how to fix it...
I want to have more than one photo in some objects like in 2nd

then always expect / send an array and map it to a list and check for the list size
final List<String> urls = city.getImageURLs();
if (urls.size() > 1) {
// add code for more images
} else {
Picasso.with(inflater.getContext()).load(urls.get(0)).placeholder(R.drawable.internet_access_placeholder).into(photo);
}

imageURL must be Json array
[
{ "name" : "Sir",
"votes" : 23,
"imageURL" : [ "http://img.prntscr.com/img?url=http://i.imgur.com/5ogv5yJ.png" ] },
{ "name" : "Bar",
"votes" : 21,
"imageURL" : [
"http://img.prntscr.com/img?url=http://i.imgur.com/G1qQb9Q.png",
"http://www.dreamhost.com/blog/wp-content/uploads/2015/10/DHC_blog-image-01-300x300.jpg",
"http://lh5.ggpht.com/yt6SnO_2jOIot1FhQYGiVXd_IQWBOCmQ1UJBddyau3Wzw1ZgpdeQwpO7TRFnux3Dirk=w300",
"http://i.vimeocdn.com/portrait/4728693_300x300.jpg",
"http://www.raspberrypi.org/wp-content/themes/mind-control/images/octocat.jpg"
]
}
]
and your model must be like that
public class City extends RealmObject {
private String name;
private long votes;
private List<String> imageURL;
.
.
.
}
