how to parse this jsonarray using GSON library

This is my jsonarray.
[
{
"id": 3,
"title": "Best Seller",
"promotedProducts": [
{
"product": {
"id": 4208,
"name": "Gents T-Shirt With Navy Blue Collar cuff",
"reviewList": [],
"productDetail": {
"id": 4207,
"length": 33,
"breadth": 27
},
"attributeList": [
{
"id": 1,
"productId": 4208
}
]
}
},
{
"product": {
"id": 4208,
"name": "Gents T-Shirt With Navy Blue Collar cuff",
"reviewList": [],
"productDetail": {
"id": 4207,
"length": 33,
"breadth": 27
},
"attributeList": [
{
"id": 1,
"productId": 4208
}
]
}
}
]
}
]
I had created Homecollection class for it.also added following code for parsing.I had also created subclasses for product,promotedProducts,productDetail,attributeList,images.its give me as reponse of two items but other details are coming empty
Gson gson = new Gson();
HomeProducts homeProducts = HomeProducts.getInstance();
List<HomeCollections> collectionList = new ArrayList<HomeCollections>();
collectionList = Arrays.asList(gson.fromJson(response.toString(), HomeCollections[].class));

Create a Model class like this.
public class ProductDetail
{
public int id { get; set; }
public int length { get; set; }
public int breadth { get; set; }
}
public class AttributeList
{
public int id { get; set; }
public int productId { get; set; }
}
public class Product
{
public int id { get; set; }
public string name { get; set; }
public List<object> reviewList { get; set; }
public ProductDetail productDetail { get; set; }
public List<AttributeList> attributeList { get; set; }
}
public class PromotedProduct
{
public Product product { get; set; }
}
public class HomeCollections
{
public int id { get; set; }
public string title { get; set; }
public List<PromotedProduct> promotedProducts { get; set; }
}
Now use the GSON like this. Here url is the source link.You will get the response as a model. Now
response.promotedProducts will give you all list of items.
InputStream source = retrieveStream(url);
Gson gson = new Gson();
Reader reader = new InputStreamReader(source);
HomeCollections response = gson.fromJson(reader, HomeCollections.class);

use this classes to get this data

You can use the following website to parse:
jsonschema2pojo
A version would be:
public class PromotedProduct {

}
/**

The main class:
public class Example {

#SerializedName("title")
#Expose
private String title;
#SerializedName("promotedProducts")
#Expose
private List<PromotedProduct> promotedProducts = new ArrayList<PromotedProduct>();

*/
public void setAttributeList(List<AttributeList> attributeList) {

}
Of course you need to polish it a bit. I just copy-pasted the generated files. You can change your main class there from "Example" to whatever you may like plus remove some stuff you do not like.

ListView not displaying items(using retrofit to retrieve list)

Hello guys I'm still learning android things and this is my first time that I 'm building a list using retrofit to populate it from server. I receive no error, app doesn't crash, and my log show that I receive data from server.
My Adapter for listview:
public class TransactionsAdapter extends BaseAdapter {
ArrayList<Transactions> transactions;
public TransactionsAdapter(ArrayList<Transactions> transactions) {
this.transactions=transactions;
}
#Override
public int getCount() {
return 0;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view=null;
ViewHolder viewHolder = null;
if(convertView == null)
{
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.izvjestaji_item,parent,false);
viewHolder = new ViewHolder(view);
view.setTag(viewHolder);
}
else{
view = convertView;
viewHolder= (ViewHolder) view.getTag();
}
Transactions transactions = (Transactions) getItem(position);
if(transactions != null) {
viewHolder.datum.setText(transactions.getPurchaseDate());
viewHolder.partner.setText(transactions.getMerchantName());
viewHolder.iznos.setText(transactions.getTransactionMoneyAmount().toString());
viewHolder.brojbodova.setText(transactions.getSalesAmount().toString());
}
return view;
}
private class ViewHolder{
TextView datum;
TextView partner;
TextView iznos;
TextView brojbodova;
public ViewHolder(View view) {
this.datum = (TextView) view.findViewById(R.id.izvjestaji_datum);
this.partner = (TextView) view.findViewById(R.id.izvjestaji_partner);
this.iznos = (TextView) view.findViewById(R.id.izvjestaji_iznos);
this.brojbodova=(TextView)view.findViewById(R.id.izvjestaji_brojbodova);
}
}
}

#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
list=(ListView)view.findViewById(R.id.izvjestaji_list);
showList();
// Setup any handles to view objects here
// EditText etFoo = (EditText) view.findViewById(R.id.etFoo);
}
public void showList(){

list.setAdapter(transactionsAdapter);
}
}
#Override
public void onFailure(Call<List<Transactions>> call, Throwable t) {
Log.d("Error","Def error");
}
});
}
}
2 xml files (one is from fragment and other is single item in list )
Fragment layout :

In my preview I only get empty fragment

In TransactionAdapter class you have not implemented the overriding methods
use these
#Override
public int getCount() {
return transactions.size();
}
#Override
public Object getItem(int position) {
return transactions.get(position);
}
#Override
public long getItemId(int position) {
return position;
}

Change to this
#Override
public int getCount() {
return transactions.size();
}
#Override
public Object getItem(int position) {
return transactions.get(position);
}
#Override
public long getItemId(int position) {
return position;
}

Can't populate layout with JSON data

I'm trying to populate a layout of mine by looping through some requested JSON (I use Retrofit).
When I try to populate the layout manually (like below), it displays fine:
Post post1 = new Post("1", "1", "This is a message.");
But if I try to populate it with the requested JSON data, the layout doesn't get populated nor does it display on my screen. Only the layout with "This is a message." is displayed.
Here is the code within my onCreateView() for my fragment:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
ListView listView = (ListView) view.findViewById(R.id.listview_posts);
final ArrayList<Post> arrayOfUsers = new ArrayList<Post>();
// This works fine. It populates the layout as it should.
Post post1 = new Post("1", "1", "This is a message.");
arrayOfUsers.add(post1);
final RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint(BASE_URL)
.build();
final ApiEndpointInterface apiService = restAdapter.create(ApiEndpointInterface.class);
apiService.getJsonStuff(1, new Callback<PostData>() {
#Override
public void success(PostData postData, Response response) {
// This doesn't work either
Post post2 = new Post("1", "1", "This is a message2.");
arrayOfUsers.add(post2);
for (Post p : postData.data) {
// This does not work. The layout isn't populated nor does it display.
Post posty = new Post(p.getId(), p.getUserId(), p.getContent());
arrayOfUsers.add(posty);
// The JSON is being read correctly, since this prints out the right values.
Log.d("MESSAGE", p.getMessage());
}
}
#Override
public void failure(RetrofitError retrofitError) {
retrofitError.printStackTrace();
}
});
PostAdapter adapter = new PostAdapter(getActivity(), arrayOfUsers);
listView.setAdapter(adapter);
return view;
}
The callback:
void getJsonStuff(#Path("user_id") int userId, Callback<PostData> response);
Post model:

In the scenario that works for you -> you are doing the things sequentially: create the Post object - add it to the list - create the adapter based on the non-empty list - set the adapter on the list.
In the scenario that doesn't work, you are doing them asynchronously: create empty list - trigger request for data (but no data yet) - create adapter - set the adapter on the list - at some undetermined moment in the future data arrives. The problem is that in this case the adapter doesn't know that anything changed, so you need to notify it (at the end of your success callback):
adapter.notifyDataSetChanged()

Your getJsonStuff method should be declared something like...
getJsonStuff(int id, Callback<List<Post>> callback)

How to show data in spinner android?

I am using spinner which get populated dynamically from data base
here is my code
<Spinner
android:id="#+id/spnOrdrPrdBrand"
style="#style/ButtonStyleSpinner"
android:layout_marginTop="5dp"
android:hint="#string/select"
android:paddingLeft="5dp" />
List<Brand> brandList = new ArrayList<Brand>();
if(!custId.equals("0")){
brandList = cCon.getBrandList(custId);
}
// Sorting
//Collections.sort(brandList);
//Brand Lst
ArrayAdapter<Brand> brandAdp = new ArrayAdapter<Brand>(this,android.R.layout.simple_spinner_item,brandList.toArray(new Brand[brandList.size()]));
brandAdp.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnOrdrPrdBrand.setAdapter(brandAdp);
data is thr in brandList object
but while populating showing me object name instead actual brand name.
I am using
public class Brand implements Comparable<Brand>{
// private variables
protected int brandId;
protected String brandNm;
// Empty constructor
public Brand() {
}
// constructor
public Brand(int brandId, String brandNm) {
this.brandId = brandId;
this.brandNm = brandNm;
}
/**
* #return the brandId
*/
public int getBrandId() {
return brandId;
}
/**
* #param brandId the brandId to set
*/
public void setBrandId(int brandId) {
this.brandId = brandId;
}
/**
* #return the brandNm
*/
public String getBrandNm() {
return brandNm;
}
/**
* #param brandNm the brandNm to set
*/
public void setBrandNm(String brandNm) {
this.brandNm = brandNm;
}
#Override
public int compareTo(Brand another) {
if (this.brandNm.equals(another.brandNm)) {
return ((Integer.valueOf(this.brandId)).compareTo(Integer.valueOf(another.brandId)));
} else {
return this.brandNm.compareTo(another.brandNm);
}
}
}
so how to resolve for the same

What are you showing is the toString implementation of Object. If you do not want to have a custom adapter, you can override toString() in your Brand class and let it returns the String you want to show,

parcelable is not working android

I'm trying to send an ArrayList of custom objects to the next activity but its not working for me. I've been all day trying to implement Parcelable with no luck at all. I've done my research here on SO but i'm still getting an error: Cannot convert Parceable[] to ArraList<Song> This is my code for parceling my object:
// Parcelling part
public Song(Parcel in){
this._id = in.readInt();
this.name = in.readString();
this.path = in.readString();
this.artistId = in.readInt();
this.albumId = in.readInt();
}
#Override
public int describeContents(){
return 0;
}
public static final Parcelable.Creator<Song> CREATOR = new Parcelable.Creator<Song>() {
public Song createFromParcel(Parcel in) {
return new Song(in);
}
public Song[] newArray(int size) {
return new Song[size];
}
};
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(_id);
dest.writeString(name);
dest.writeString(path);
dest.writeInt(artistId);
dest.writeInt(albumId);
}
In my first activity i just:
ArrayList<Song> songs = db.selectAllSongs();
playerActivity.putParcelableArrayListExtra("songs", songs);
And in my second activity i just:
ArrayList<Song> songs = getIntent().getParcelableArrayExtra("songs");
I don't know why im getting an error when i'm implementing Parceable. I need a little guiding. Thanks in advance.

I hope this will help for you. In this way i am using parcellable values
public class Channel implements Serializable, Parcelable {
/** */
private static final long serialVersionUID = 4861597073026532544L;
private String cid;
private String uniqueID;
private String name;
private String logo;
/**
* #return the cid
*/
public String getCid() {
return cid;
}
/**
* #param cid
* the cid to set
*/
public void setCid(String cid) {
this.cid = cid;
}
/**
* #return the uniqueID
*/
public String getUniqueID() {
return uniqueID;
}
/**
* #param uniqueID
* the uniqueID to set
*/
public void setUniqueID(String uniqueID) {
this.uniqueID = uniqueID;
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name
* the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the logo
*/
public String getLogo() {
return logo;
}
/**
* #param logo
* the logo to set
*/
public void setLogo(String logo) {
this.logo = logo;
}
public Channel(Parcel in) {
super();
readFromParcel(in);
}
public static final Parcelable.Creator<Channel> CREATOR = new Parcelable.Creator<Channel>() {
public Channel createFromParcel(Parcel in) {
return new Channel(in);
}
public Channel[] newArray(int size) {
return new Channel[size];
}
};
public void readFromParcel(Parcel in) {
String[] result = new String[23];
in.readStringArray(result);
this.cid = result[0];
this.uniqueID = result[1];
this.name = result[2];
this.logo = result[3];
}
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel dest, int flags) {
dest.writeStringArray(new String[] { this.cid, this.uniqueID,
this.name, this.logo});
}}
And in Activity class
bundle.putParcelableArrayList("channel",
(ArrayList<Channel>) channels);
And in the second Activity screen get the bundle parcelable array like this
Bundle getBundle = this.getIntent().getExtras();
List<Channel> channelsList = getBundle.getParcelableArrayList("channel");

The method Intent.getParcelableArrayExtra() (link) returns an array of parcelable objects. You're assigning that to an ArrayList object, and the compiler is complaining because ArrayLists aren't arrays.
Try using getParcelableArrayListExtra() instead.
