I have a ListSourceAdapter.java class,
class ListSourceViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
ItemClickListener itemClickListener;
TextView source_title;
CircleImageView source_image;
public ListSourceViewHolder(View itemView) {
super(itemView);
source_title = (TextView) itemView.findViewById(R.id.source_name);
source_image = (CircleImageView) itemView.findViewById(R.id.source_image);
}
#Override
public void onClick(View v) {
itemClickListener.onClick(v, getAdapterPosition(), false);
}
}
public class ListSourceAdapter extends RecyclerView.Adapter<ListSourceViewHolder> {
private Context context;
private WebSite webSite;
public ListSourceAdapter(Context context, WebSite webSite) {
this.context = context;
this.webSite = webSite;
}
#Override
public ListSourceViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View itemView = inflater.inflate(R.layout.source_layout, parent, false);
return new ListSourceViewHolder(itemView);
}
#Override
public void onBindViewHolder(ListSourceViewHolder holder, int position) {
StringBuilder iconBetterAPI = new StringBuilder("https://icons.better-idea.org/allicons.json?url=");
iconBetterAPI.append(webSite.getSources().get(position).getUrl());
}
#Override
public int getItemCount() {
return webSite.getSources().size();
}
}
in onBindView Im try to use getUrl() but it says cannot resolve method
my WebSite.java model class like below
public class WebSite {
private String status;
private List<Source> sources;
public WebSite() {
}
public WebSite(String status, List<Source> sources) {
this.status = status;
this.sources = sources;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public List<Source> getSources() {
return sources;
}
public void setSources(List<Source> sources) {
this.sources = sources;
}
}
Source.java file like below
class UrlsToLogs {
private String small, medium, large;
public String getSmall() {
return small;
}
public void setSmall(String small) {
this.small = small;
}
public String getMedium() {
return medium;
}
public void setMedium(String medium) {
this.medium = medium;
}
public String getLarge() {
return large;
}
public void setLarge(String large) {
this.large = large;
}
}
public class Source {
private String id, name, description, url, category, language, country;
private UrlsToLogs urlsToLogs;
private List<String> sortByAvailable;
public Source() {
}
public Source(String id, String name, String description, String url, String category, String language, String country, UrlsToLogs urlsToLogs, List<String> sortByAvailable) {
this.id = id;
this.name = name;
this.description = description;
this.url = url;
this.category = category;
this.language = language;
this.country = country;
this.urlsToLogs = urlsToLogs;
this.sortByAvailable = sortByAvailable;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {

}
public List<String> getSortByAvailable() {
return sortByAvailable;
}
public void setSortByAvailable(List<String> sortByAvailable) {
this.sortByAvailable = sortByAvailable;
}
}
IconBetterIdeaService interface like below
public interface IconBetterIdeaService {
#GET
Call<IconBetterIdea> getIconUrl(#Url String url);
}
ItemClickListner interface like below
public interface ItemClickListener {
void onClick(View view, int position, boolean isLongClick);
}
why I can't access getUrl(), what did I do wrong in my code?
Try this create separate class like this
public class WebSite {
private String status;
private List<Source> sources;
public WebSite() {
}
public WebSite(String status, List<Source> sources) {
this.status = status;
this.sources = sources;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public List<Source> getSources() {
return sources;
}
public void setSources(List<Source> sources) {
this.sources = sources;
}
}
than
public class Source {
private String id, name, description, url, category, language, country;
private UrlsToLogs urlsToLogs;
private List<String> sortByAvailable;
public Source() {
}
public Source(String id, String name, String description, String url, String category, String language, String country, UrlsToLogs urlsToLogs, List<String> sortByAvailable) {
this.id = id;
this.name = name;
this.description = description;
this.url = url;
this.category = category;
this.language = language;
this.country = country;
this.urlsToLogs = urlsToLogs;
this.sortByAvailable = sortByAvailable;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public String getLanguage() {
return language;
}
public void setLanguage(String language) {
this.language = language;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public UrlsToLogs getUrlsToLogs() {
return urlsToLogs;
}
public void setUrlsToLogs(UrlsToLogs urlsToLogs) {
this.urlsToLogs = urlsToLogs;
}
public List<String> getSortByAvailable() {
return sortByAvailable;
}
public void setSortByAvailable(List<String> sortByAvailable) {
this.sortByAvailable = sortByAvailable;
}
}
than
public class UrlsToLogs {
private String small, medium, large;

After debugging the code can see Message is success, code =200, but userdata size ==0 please help me to get rid of this error
Check again the way that you are calling the api, even your userid is getting null, probably it's getting null in the user, but the response is 200 bc there was no error, simply no user with that id.
I have initialized the arraylist globally(mDataset). I'm trying to populate the arraylist based on some conditions.
code snippet in which error is occurring.
Error is occurring when i try to initialize object product with the value received from the fire.getValue() in for loop
mProductReference.child("Electronics").addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot fire : dataSnapshot.getChildren())
{
Product product = fire.getValue(Product.class);
if(product.getId().equals(key)) {
mDataSet.add(product);
}
//Toast.makeText(MyProduct.this,mDataSet.size()+ "", Toast.LENGTH_SHORT).show();
}
mAdapter.refresh(mDataSet);
mRecyclerView.setAdapter(mAdapter);

In debug mode, string response in objectMapper shows correct response, string response in attractionMainResponse giving a success but can't map the attractionDetailModel, giving null.
Is this about a Jackson ObjectMapper? Is it possible to create a smaller example, that makes it easier to give a solution.
I have the following POJO classes

public class GroupUser {

int isNew;
// generated and cached
#JsonProperty("user_name")
String userName;
public GroupUser() {
}
#JsonIgnore
public GroupUser(String email, int isCreator) {
this.userId = 0;
this.email = email;
this.Creator = isCreator;
this.isAdmin = isCreator;
if (isCreator == 1) {
this.status = Group.STATE_ACCEPTED;
this.isNew = 0;
} else {
this.isNew = 1;
this.status = Group.STATE_INVITED;
}
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;

I am using jackson library to serialize the Group Object to JSON like below:
ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.WRITE_EMPTY_JSON_ARRAYS, true);
return mapper.writeValueAsString(group);
But the Users fields never gets serialized, no matter what groupUsers always is an empty array []. Any idea what am I doing wrong?
I'm trying to figure out a way to transform this JSON String into a Java object graph but I'm unable to do so. Below, I've inserted my JSON String, and my two classes. I've verified that its a valid json structure. I've been trying googles api (http://sites.google.com/site/gson/gson-user-guide) but it doesn't map the nested Photo Collection. Any ideas or alternate libraries?
{"photos":{"page":1,"pages":73514,"perpage":50,"total":"3675674","photo":[{"id":"5516612975","owner":"23723942#N07","secret":"b8fb1fda57","server":"5213","farm":6,"title":"P3100006.JPG","ispublic":1,"isfriend":0,"isfamily":0},{"id":"5516449299","owner":"81031835#N00","secret":"67b56722da","server":"5171","farm":6,"title":"Kaiser Boys Volleyball","ispublic":1,"isfriend":0,"isfamily":0}]},"stat":"ok"}

Use Jackson. It'll take care of converting to and from JSON. It provides multiple ways of approaching conversion, and is well-integrated with frameworks like Spring. Definitely one to know.
