How do i pass objects from 1 class to another?

I have 3 classes: MainActivity, homePage and createPage; and a list List<Recipe> recipeList = new ArrayList<>() in MainActivity.
The user enters the homePage from the MainActivity. From homePage, the user can enter createPage and create a new recipe. This new recipe is intended to be passed back to MainActivity.
I've searched online and came across parcels. But when I tried, I get a NullPointerException.
Code for createPage where the list is passed on
ArrayList<Recipe> rList = new ArrayList<>();
Recipe r = new Recipe(...);
rList.add(r)
Intent i = new Intent();
Bundle b = new Bundle();
b.putParcelableArrayList("recipe", (ArrayList<? extends Parcelable>) rList);
i.putExtras(b);
i.setClass(createPage.this, homePage.class);
startActivity(i);
Code for homePage where the list is received.
Is there something wrong with the getIntent()? Because when moving from MainActivity to homePage, it doesn't receive a bundle. Is this causing the error?
Intent intent = getIntent();
Bundle b = this.getIntent().getExtras();
if (b != null) {
Recipe r = b.getParcelable("recipe");
recipeList.add(r);
}
Code for Recipe class
public class Recipe implements Parcelable {
private String name;
private String description;
private String ingredients;
private int duration;
private String steps;
private int thumbnail;
protected Recipe(Parcel in) {
name = in.readString();
description = in.readString();
ingredients = in.readString();
duration = in.readInt();
steps = in.readString();
thumbnail = in.readInt();
}
public static final Creator<Recipe> CREATOR = new Creator<Recipe>() {
#Override
public Recipe createFromParcel(Parcel in) {
return new Recipe(in);
}
#Override
public Recipe[] newArray(int size) {
return new Recipe[size];
}
};
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 getIngredients() {
return ingredients;
}
public void setIngredients(String ingredients) {
this.ingredients = ingredients;
}
public int getDuration() {
return duration;
}
public void setDuration(int duration) {
this.duration = duration;
}
public String getSteps() { return steps; }
public void setSteps(String steps) { this.steps = steps; }
public int getThumbnail() { return thumbnail; }
public Recipe() {}
public Recipe(String name, int duration, String ingredients, String description, String steps, int thumbnail) {
this.name = name;
this.description = description;
this.ingredients = ingredients;
this.duration = duration;
this.steps = steps;
this.thumbnail = thumbnail;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeString(name);
parcel.writeString(description);
parcel.writeString(ingredients);
parcel.writeInt(duration);
parcel.writeString(steps);
parcel.writeInt(thumbnail);
}
}

you are writing into Parcelable whole array under "recipe" key
b.putParcelableArrayList("recipe", (ArrayList<? extends Parcelable>) rList);
but on onther side you are looking not for list but for single Recipe item under same key
Recipe r = b.getParcelable("recipe");
you should use getParcelableArrayList or if you have only one Recipe for passing to another Activity just use putParcelable (not list)

Alternatively you can use serializable, that will be less complex.
For reference : https://stackoverflow.com/a/2736612/9502601
Eventhough parcellables are more faster but if you want a less complex solution then you can go for it.

https://stackoverflow.com/a/23647471/9502601

You can use this gson Lib for this
implementation 'com.google.code.gson:gson:2.8.9'
Send Data with Intent
Recipe r = new Recipe(...);
String recipeString = new Gson().toJson(r);
intent.putExtra("recipe",recipeString);
// For ArrayList
ArrayList<Recipe> recipeList = new ArrayList<>();
String recipeString = new Gson().toJson(recipeList);
intent.putExtra("recipeList",recipeString);
Receive Data From Intent
Recipe r = new Gson().fromJson(intent.getStringExtra("recipe"), Recipe.class);
// For Array List
Type listType = new TypeToken<ArrayList<Recipe>>(){}.getType();
ArrayList<Recipe> recipeList = new Gson().fromJson(intent.getStringExtra("recipeList"),listType);

writing multiple objects to parcel

I am trying to save an enum 'Status' into a custom class that implements parcelable. I have found online how I can save Strings, ints or enums in one class that implements parcelable, but not how I can save these three things all at once. I am sorry if the solution is obvious, but I just can't figure it out.
Here is what my enum looks like:
public enum Status {
INITIALIZED, UPDATED, DELETED
}
And this is what I have so far:
public class Recipe implements Parcelable{
private String id;//this should be an int, same problem
private String recipeName;
private String recipePreperation;
private Status status;
private final static int MAX_PREVIEW = 50;
public Recipe(int parId, String parRecipeName, String parRecipePreperation) {
this.id = "" + parId;
this.recipeName = parRecipeName;
this.recipePreperation = parRecipePreperation;
this.status = Status.INITIALIZED;
}
public Recipe(Parcel in){
String[] data = new String[4];
in.readStringArray(data);
this.id = data [0];
this.recipeName = data[1];
this.recipePreperation = data[2];
this.status = data[3];//what I intend to do, I know this is wrong
}
public int GetId() {
return Integer.parseInt(id);
}
public String GetRecipeName() {
return this.recipeName;
}
public void SetRecipeName(String parRecipeName) {
this.recipeName = parRecipeName;
}
public String GetRecipePreperation() {
return this.recipePreperation;
}
public void SetRecipePreperation(String parRecipePreperation) {
this.recipePreperation = parRecipePreperation;
}
public Status GetStatus() {
return this.status;
}
public void SetStatus(Status parStatus) {
this.status = parStatus;
}
public String toString() {
String recipe = this.recipeName + "\n" + this.recipePreperation;
String returnString;
int maxLength = MAX_PREVIEW;
if (recipe.length() > maxLength) {
returnString = recipe.substring(0, maxLength - 3) + "...";
} else {
returnString = recipe;
}
return returnString;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int arg1) {
dest.writeStringArray(new String [] {
this.id,
this.recipeName,
this.recipePreperation,
this.status//what I intend to do, I know this is wrong
});
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public Recipe createFromParcel(Parcel in) {
return new Recipe(in);
}
public Recipe[] newArray(int size) {
return new Recipe[size];
}
};
}
How do I save an int, an array of strings and an enum into a class that implements the parcelable, so it can writeToParcel()?

There's no need to read and write to/from string array. Just write each string and finally the status as Serializable. This is how I fix it.
public Recipe(Parcel in){
this.id = in.readString();
this.recipeName = in.readString();
this.recipePreperation = in.readString();
this.status = (Status) in.readSerializable();
}
public void writeToParcel(Parcel dest, int arg1) {
dest.writeString(this.id);
dest.writeString(this.recipeName);
dest.writeString(this.recipePreperation);
dest.writeSerializable(this.status);
}

How do I send an object with arbitrary types in it to another activity?

I'm pretty new to Android programming and I've ran into this issue.
I have an object I am trying to send into a new activity, which is an instance of this class:
public final class BusinessEntity extends com.google.api.client.json.GenericJson {
/**
* The value may be {#code null}.
*/
#com.google.api.client.util.Key
private Contact contact;
/**
* The value may be {#code null}.
*/
#com.google.api.client.util.Key
#com.google.api.client.json.JsonString
private java.lang.Long id;
/**
* The value may be {#code null}.
*/
#com.google.api.client.util.Key
private java.lang.String imageUrl;
/**
* The value may be {#code null}.
*/
#com.google.api.client.util.Key
private Person owner;
/**
* The value may be {#code null}.
*/
#com.google.api.client.util.Key
private java.util.List<java.lang.String> tag;
/**
* The value may be {#code null}.
*/
#com.google.api.client.util.Key
private java.lang.String type;
I have tried converting it to gson and sending it in a Bundle with the Intent, and converting it back to a BusinessEntity in the new Activity The problem is I can't deserialize it in the new activity because it contains objects of an arbitrary type. I have tried parsing it as a JsonArray, but I get the exception: "IllegalStateException: This is not a JSON Array." I guess because the object is not in a collection.
There are a lot of attributes in the Person and Contact class that I would like to be able to access in the new Activity, but I would also like to avoid sending each attribute separately.
Here's what I have in the first class:
Intent i = new Intent(mActivity, DetailsActivity.class);
Bundle b = new Bundle();
Gson gson = new Gson();
String business = gson.toJson(businesses.get(position));
b.putString("business", business);
i.putExtras(b);
startActivity(i);
And here's what I have in the second class:
Bundle b = getIntent().getExtras();
String json = b.getString("business");
Gson gson = new Gson();
JsonParser parser = new JsonParser();
JsonArray array = parser.parse(json).getAsJsonArray();
Contact contact = gson.fromJson(array.get(0), Contact.class);
Long id = gson.fromJson(array.get(1), Long.class);
String imageURL = gson.fromJson(array.get(2), String.class);
Person person = gson.fromJson(array.get(3), Person.class);
List<String> tag = gson.fromJson(array.get(4), List.class);
But like I said I get a IllegalStateException at
JsonArray array = parser.parse(json).getAsJsonArray();
What is a good way to do this where I don't have to send each attribute separately?
--------------------------------------EDIT-------------------------------------------------------
I tried Parcelable, Serializable, Gson, everything... I was getting errors each time trying to cast the object back into a BusinessEntity in the new activity.
The workaround I created is I made a new class called SimpleBusiness that consists of all the attributes of BusinessEntity, Contact, and Person, implements Parcelable, and takes a BusinessEntity as a parameter in its constructor. I create a new SimpleBusiness object from the BusinessEntity I went to send to the new activity, send it with the intent, and get it from the intent from the new activity. It's kind of a weird workaround but it works perfectly.
Here is the new Class:
/**

private String address2;

public SimpleBusiness(){
}
/**

*/

//i.putExtras(b);

And in the DetailsActivity class:
Intent i = getIntent();
Bundle b = i.getExtras();
business = (SimpleBusiness)b.get("business");
Thanks for the help guys. It probably would have taken a lot longer if I didn't have the advice you guys gave me.
--------------------------------------------Edit 2--------------------------------------------
Switched to passing a BusinessEntity object directly with an EventBus. So much easier.
http://www.stevenmarkford.com/passing-objects-between-android-activities/
Pass the object:
Intent i = new Intent(mActivity, DetailsActivity.class);
BusinessEntity business = businesses.get(position);
de.greenrobot.event.EventBus.getDefault().postSticky(business);
startActivity(i);
Retrieve the object:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.busEntity = (BusinessEntity) EventBus.getDefault().removeStickyEvent(BusinessEntity.class);
setContentView(R.layout.activity_details);
}

EventBus makes your life so much easier, see the example and links in my answer to this question: Saving information from one fragment and dialog if the user navigates to another fragment in essence, no need to do any serialization or anything, just put the object on the eventbus and grab it again anywhere in your code (in another Activity, Fragment, Service etc..)

If you are able to modify BusinessEntity, then have it implement Serializable. You may then put the business as an extra:
//To put the object as an extra
...
BusinessEntity business = businesses(get(position));
Intent intent = new Intent(mActivity, DetailsActivity.class);
intent.putExtra("business", business); // Where business is now a `Serializable`
...
//To retrieve the object (in your second class).
//TODO -- Include check to see if intent has the extra first
BusinessEntity retrievedBusiness = (BusinessEntity) intent.getSerializableExtra("business")

You should use Parcelable Objects
https://github.com/codepath/android_guides/wiki/Using-Parcelable

You can do this via Serializable interface. Just let your BusinessEntity implement Serializable, like this:
public final class BusinessEntity extends com.google.api.client.json.GenericJson implements Serializable {
//your code here
...
...
}
Then create your intent and put an extra to it:
Intent i = new Intent(mActivity, DetailsActivity.class);
i.putExtra("BusinessEntity", yourBuisnessEntityObject);
startActivity(i);
And finally in your DetailsActivity:
BusinessEntity business = (BusinessEntity) getIntent().getSerializableExtra("BusinessEntity");
Voila! You have your BusinessEntity object in DetailsActivity.
EDIT:
Back to your code, I think the problem is that you put a JsonObject extra not a JsonArray. You should do the same things that you posted firstly, but with one correction:
JsonObject object = parser.parse(json).getAsJsonObject(); and then parse it as JsonObject by keys.

Pass List with custom object to another activity android

I have a List<News> new ArrayList<News>(); I need to pass this list to another activity and retrieve object from it to assign it to String values.
News.java
public class News
{
String title;
String description;
String thumbnail;
String newsUrl;
String body;
String newsBigImage ;
String newsComments ;
String newsViews;
String publishedDate;
String articleGuid;
String newsSourceId;
String newsId ;
String publisherName;
String newsSourceTitle;
String color;
News(String title, String description, String thumbnail, String newsUrl, String body, String newsBigImage, String newsComments, String newsViews,
String publishedDate,
String articleGuid,
String newsSourceId,
String newsId ,
String publisherName,
String newsSourceTitle )
{
this.title = title;
this.description = description;
this.articleGuid =articleGuid;
this.thumbnail = thumbnail;
this.newsUrl = newsUrl;
this.body = body;
this.newsBigImage = newsBigImage;
this.newsComments = newsComments;
this.newsViews = newsViews;
this.publishedDate = publishedDate;
this.newsId = newsId;
this.newsSourceId = newsSourceId;
this.publisherName = publisherName;
//this.color = color;
this.newsSourceTitle =newsSourceTitle;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getThumbnail() {
return thumbnail;
}
public void setThumbnail(String thumbnail) {
this.thumbnail = thumbnail;
}
public String getNewsUrl() {
return newsUrl;
}
public void setNewsUrl(String newsUrl) {
this.newsUrl = newsUrl;
}
public String getBody() {
return body;
}
public void setBody(String body) {
this.body = body;
}
public String getNewsBigImage() {
return newsBigImage;
}
public void setNewsBigImage(String newsBigImage) {
this.newsBigImage = newsBigImage;
}
public String getNewsComments() {
return newsComments;
}
public void setNewsComments(String newsComments) {
this.newsComments = newsComments;
}
public String getNewsViews() {
return newsViews;
}
public void setNewsViews(String newsViews) {
this.newsViews = newsViews;
}
public String getPublishedDate() {
return publishedDate;
}
public void setPublishedDate(String publishedDate) {
this.publishedDate = publishedDate;
}
public String getArticleGuid() {
return articleGuid;
}
public void setArticleGuid(String articleGuid) {
this.articleGuid = articleGuid;
}
public String getNewsSourceId() {
return newsSourceId;
}
public void setNewsSourceId(String newsSourceId) {
this.newsSourceId = newsSourceId;
}
public String getNewsId() {
return newsId;
}
public void setNewsId(String newsId) {
this.newsId = newsId;
}
public String getPublisherName() {
return publisherName;
}
public void setPublisherName(String publisherName) {
this.publisherName = publisherName;
}
public String getNewsSourceTitle() {
return newsSourceTitle;
}
public void setNewsSourceTitle(String newsSourceTitle) {
this.newsSourceTitle = newsSourceTitle;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
}
I pass values like:-
myNewsList.add(new News(title, description, thumbnail, newsUrl, body, newsBigImage, newsComments, newsViews, publishedDate, articleGuid, newsSourceId, newsId, publisherName, newsSourceTitle));
Then I pass this list to an ListAdapter to show it in a ListView.
itemsAdapter = new LazyAdapter(myContext, myNewsList);
newsList.setAdapter(itemsAdapter);
Now, When the user clicks a listview item, I want to pass the myNewsList to the new activity and retrieve items from it and assign it to another Strings in that class.
ewsList.setOnItemClickListener(new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0,
View arg1, int position, long arg3)
{
// TODO Auto-generated method stub
myDialog = new ProgressDialog(myContext).show(getActivity(), "Fetching news..", "Just a moment");
//News myMap = myNewsList.get(position);
Intent newsIntent = new Intent(getActivity(),NewsDetails.class);
startActivity(newsIntent);
How can I do this??

implements a parcelable interface so your class will look like
public class News implements Parcelable {
String title;
String description;
String thumbnail;
String newsUrl;
String body;
String newsBigImage ;
String newsComments ;
String newsViews;
String publishedDate;
String articleGuid;
String newsSourceId;
String newsId ;
String publisherName;
String newsSourceTitle;
String color;
protected News(Parcel in) {
title = in.readString();
description = in.readString();
thumbnail = in.readString();
newsUrl = in.readString();
body = in.readString();
newsBigImage = in.readString();
newsComments = in.readString();
newsViews = in.readString();
publishedDate = in.readString();
articleGuid = in.readString();
newsSourceId = in.readString();
newsId = in.readString();
publisherName = in.readString();
newsSourceTitle = in.readString();
color = in.readString();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(title);
dest.writeString(description);
dest.writeString(thumbnail);
dest.writeString(newsUrl);
dest.writeString(body);
dest.writeString(newsBigImage);
dest.writeString(newsComments);
dest.writeString(newsViews);
dest.writeString(publishedDate);
dest.writeString(articleGuid);
dest.writeString(newsSourceId);
dest.writeString(newsId);
dest.writeString(publisherName);
dest.writeString(newsSourceTitle);
dest.writeString(color);
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<News> CREATOR = new Parcelable.Creator<News>() {
#Override
public News createFromParcel(Parcel in) {
return new News(in);
}
#Override
public News[] newArray(int size) {
return new News[size];
}
};
}
and you can pass now this in intent extra like
intent.putExtra("newsObject", obj);
and for passing arraylist do Intent.putParcelableArrayListExtra("newsList", arr);
and in next activity get like
News news = (News)intent.getParcelableExtra("newsObject");
and for getting arraylist do
ArrayList<News> news = (ArrayList<News>)intent.getParcelableArrayListExtra("newsList");

Use Seriazable or Parceable interface implementation for this.

In NewsDetails class just you want to show the description so call getters method of model class and show there, or else follow above solution

first, create a getter method to retreive your object in adapter.. returning your List then you call your getter in your activity, then you create your intent.

Android: getParcelable returning null?

As a follow on from my last question: Passing Arraylist between activities? Using Parcelable
I'm now attempting to pass my ArrayList via Parcelable. However, when it's gotten from the other activity it returns null. I can't seem to figure out why. I've got the following...

for (int i = 0; i < size; i++) {

listOfResults is declared as ResultsList listOfResults = new ResultsList(); and filled earlier in the code It's then sent with...
Intent intent = new Intent(this ,newthing.class);
Bundle b = new Bundle();
b.putParcelable("results", listOfResults);
startActivityForResult(intent,0);
Receiving...
Bundle extras = getIntent().getExtras();
ResultsList results = extras.getParcelable("results");
I'd like to point out I'm testing this null thing by checking the size() of the Arraylist going into the Bundle and then it coming out. It goes in fine and comes out null.

Didn't attach bundle to intent! (doh!) was pointed out by a kind gent on IRC! #android-dev
