How to parse nested keys and values using JsonReader?

How to parse nested keys and values using JsonReader? - java

I am learning Java and I'm trying to make a Fortnite stat tracking app. I'm using the Fortnite tracker API and JsonReader to read the keys and values that get returned. This works fine but the problem is the stats like 'kills' etc are nested and I'm not sure how to read those.
Can I read nested keys and values using JsonReader?
I tried JSONObject but I'm not entirely sure I was using it correctly so I didn't get very far.

Above is a sample of the information that I pulled so that you can see the structure
public class MainActivity extends AppCompatActivity {

tbplatform = (EditText) findViewById(R.id.tbPlatform);
tbhandle = (EditText) findViewById(R.id.tbHandle);
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final String platform = String.valueOf(tbplatform.getText());
final String username = String.valueOf(tbhandle.getText());
AsyncTask.execute(new Runnable() {
#Override
public void run() {
// All your networking logic

try {
githubEndpoint = new URL("https://api.fortnitetracker.com/v1/profile/" + platform+ "/" + username);
} catch (MalformedURLException e) {
e.printStackTrace();
}
// Create connection
HttpsURLConnection myConnection = null;
try {
myConnection =
(HttpsURLConnection) githubEndpoint.openConnection();
} catch (IOException e) {
e.printStackTrace();
}
myConnection.setRequestProperty("TRN-Api-Key", "API_KEY_HERE");
try {
if (myConnection.getResponseCode() == 200) {
InputStream responseBody = myConnection.getInputStream();
responseBodyReader =
new InputStreamReader(responseBody, "UTF-8");
JsonReader jsonReader = new JsonReader(responseBodyReader);
jsonReader.beginObject(); // Start processing the JSON object
while (jsonReader.hasNext()) { // Loop through all keys
final String key = jsonReader.nextName(); // Fetch the next key
//Log.v(TAG, key);
if (key.equals("epicUserHandle") || key.equals("platformName") || key.equals("accountId")) { // Check if desired key
// Fetch the value as a String
final String value = jsonReader.nextString();
if (key.equals("epicUserHandle")) {
Log.v(TAG, "Gamertag: " + value);
}
if (key.equals("platformName")) {

If your response is same as explained in question. Then this will work.
//In your code after status check you need to do like this
if (myConnection.getResopnseCode() == 200) {
BufferedReader br=new BufferedReader(responseBodyReader);
String read = null, entireResponse = "";
StringBuffer sb = new StringBuffer();
while((read = br.readLine()) != null) {
sb.append(read);
}
entireResponse = sb.toString();
//You need to change name of response class
Response response = new Gson().fromJson(entireResponse , Response.class);
}

#Override
public void onBindViewHolder(#NonNull ListaNegocioAdapter.ViewHolder viewHolder, int position) {
Datum currentItem = mNegocioList.get(position);
viewHolder.nombreNegocio.setText(currentItem.getNombre());
//Picasso.get().load(currentItem.getImagenNegocios()).into(viewHolder.logoNegocio);
}
#Override
public int getItemCount() {

}
public void adicinarLista (List<Datum> listaNegocios){
this.mNegocioList = listaNegocios;
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView nombreNegocio;
public ImageView logoNegocio;
public ViewHolder(#NonNull View itemView) {
super(itemView);
nombreNegocio = itemView.findViewById(R.id.txt_nombreNegocio);
logoNegocio = itemView.findViewById(R.id.img_negocioLogo);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mListener!=null){
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION){
mListener.onItemClick(position);
}
}
}
});
}
}
}
But I can't get into the ImagenNegocio to retrieve the images url. Can somebody help me, please?

How can use two method from two different models?

When you remove all the code from your question that is superfluous, it makes the problem more obvious.
First I simplified your comparison method:
Cart.java
boolean cartContainsDifferentTypeVoyage(final String type_voyage) {
for(Voyage voyage : voyages) {
if(!type_voyage.equals(voyage.getType_voyage()) {
return true;
}
}
}
Then created an interface
interface Voyage {
String getType_voyage();
}
Bus.java
public class Bus implements Voyage {
...
private String type_voyage;
#Override
public String getType_voyage() {
return type_voyage;
}
...
}
And changed Voyage.java to Ferry.java
public class Ferry implements Voyage {
...
private String type_voyage;
...
#Override
public String getType_voyage() {
return type_voyage;
}
...
}
You may want to look at creating some more classes so that your 'model' classes are not doing to much / have so many responsibilities.

Parcelable of Custom Classes

I am currently trying to pass an ArrayList of the class event into another activity as follows.events is an ArrayList of the Event class.
Intent i = new Intent(ViewEvents.this, UserFeed.class);
i.putParcelableArrayListExtra("events",events);
startActivity(i);
I am then retrieving the data as follows:
Intent i = getIntent();
ArrayList<Event> events = i.getParcelableArrayListExtra("events");
My Issue is that I get an Umarshing unknown type code 32 at offset 5788. I am not too sure how to fix this or why this is occurring. I have posted all the code for all three classes down below.Any help would be appreciated to solve this issue.

When implementing the Parcelable interface, it is an absolute requirement that your reads and writes exactly match each other. In your case, this is your Event(Parcel) constructor and void writeToParcel().
However, your writeToParcel() implementation includes two writes that your constructor does not read.
dest.writeParcelable( this.venue,flags);
dest.writeParcelable(this.organizer,flags);
You have to either remove these or add matching reads to your constructor.
venue = in.readParcelable(Venue.class.getClassLoader());
organizer = in.readParcelable(Organizer.class.getClassLoader());

Please i need help , even if i have done any other stupid error with data parsing !!

Call setContentView(R.layout.activity_list__main_item); right after super.onCreate(savedInstanceState); or before assigning/accessing any views.

Put Parcelable via intent

I am trying to pass Parcelable object from the A activity to B activity via intent:
Intent intent = new Intent (A.this, B.class);
intent.putExtra ("post", mypost); // where post implements Parcelable`
In B Activity I got the post object in this way:
Post myPost = getIntent().getParcelableExtra("post");
In B activity myPost object fields are mixed, e.g. I have postText and postDate fields in Post model, the values of this fields in B activity are mixed.
Why this can happen? My model class look likes the following:
public class Post implements Parcelable, Serializable {
private static final long serialVersionUID = 2L;
#SerializedName("author")
private User author;
#SerializedName("comments_count")
private String commentsCount;
#SerializedName("image")
private String imageToPost;
#SerializedName("parent_key")
private String parentKey;
#SerializedName("created_date")
private String postDate;
#SerializedName("id")
private String postId;
#SerializedName("text")
private String postText;
#SerializedName("title")
private String postTitle;
#SerializedName("shared_post_id")
private String sharedPostId;
#SerializedName("url")
private String urlToPost;
#SerializedName("video")
private String videoToPost;
public Post() {
}
public Post(Parcel in) {
author = (User) in.readValue(getClass().getClassLoader());
commentsCount = in.readString();
imageToPost = in.readString();
parentKey = in.readString();
postDate = in.readString();
postId = in.readString();
postText = in.readString();
postTitle = in.readString();
sharedPostId = in.readString();
urlToPost = in.readString();
videoToPost = in.readString();
}
public static final Creator<Post> CREATOR = new Creator<Post>() {
#Override
public Post createFromParcel(Parcel in) {
return new Post(in);
}
#Override
public Post[] newArray(int size) {
return new Post[size];
}
};
public User getAuthor() {
return author;
}
public void setAuthor(User author) {
this.author = author;
}
public String getPostDate() {
return postDate;
}
public void setPostDate(String postDate) {
this.postDate = postDate;
}
public String getPostTitle() {
return postTitle;
}
public void setPostTitle(String postTitle) {
this.postTitle = postTitle;
}
public String getPostText() {
return postText;
}
public void setPostText(String postText) {
this.postText = postText;
}
public String getPostId() {
return postId;
}
public void setPostId(String postId) {
this.postId = postId;
}
public String getUrlToPost() {
return urlToPost;
}
public void setUrlToPost(String urlToPost) {
this.urlToPost = urlToPost;
}
public String getImageToPost() {
return imageToPost;
}
public void setImageToPost(String imageToPost) {
this.imageToPost = imageToPost;
}
public String getVideoToPost() {
return videoToPost;
}
public void setVideoToPost(String videoToPost) {
this.videoToPost = videoToPost;
}
public String getParentKey() {
return parentKey;
}
public void setParentKey(String parentKey) {
this.parentKey = parentKey;
}
public String getCommentsCount() {
return commentsCount;
}
public void setCommentsCount(String commentsCount) {
this.commentsCount = commentsCount;
}
public String getSharedPostId() {
return sharedPostId;
}
public void setSharedPostId(String sharedPostId) {
this.sharedPostId = sharedPostId;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeValue(author);
dest.writeString(commentsCount);
dest.writeString(imageToPost);
dest.writeString(parentKey);
dest.writeString(postDate);
dest.writeString(postId);
dest.writeString(postText);
dest.writeString(postTitle);
dest.writeString(sharedPostId);
dest.writeString(urlToPost);
dest.writeString(videoToPost);
}
}

Add describeContents and writeToParcel.
Examples:
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeString(email);
dest.writeString(pass);
dest.writeFloat(amountPaid);
dest.writeString(url);
dest.writeInt(age);
}
