How can I make my custom objects Parcelable?
(11 answers)
Closed 6 years ago.
I am trying to learn parcelable .Earlier I was using get and set function but now I am using parcelable to pass the object to other class I made the passdata class and implemented the parcelable but how I can add the list to the class object.
class Passdata implements Parcelable {
private String title,album;
private long duration;
private Uri data,album_art;
public String getTitle() {
return title;
}
void setTitle(String title) {
this.title = title;
}
public String getAlbum() {
return album;
}
void setAlbum(String album) {
this.album = album;
}
public long getDuration() {
return duration;
}
void setDuration(long duration) {
this.duration = duration;
}
public Uri getData() {
return data;
}
void setData(Uri data) {
this.data = data;
}
public Uri getAlbum_art() {
return album_art;
}
void setAlbum_art(Uri album_art) {
this.album_art = album_art;
}
Passdata(Parcel in) {
title = in.readString();
album = in.readString();
duration = in.readLong();
data = in.readParcelable(Uri.class.getClassLoader());
album_art = in.readParcelable(Uri.class.getClassLoader());
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(title);
dest.writeString(album);
dest.writeLong(duration);
dest.writeParcelable(data, flags);
dest.writeParcelable(album_art, flags);
}
#Override
public int describeContents() {
return 0;
}
public static final Creator<Passdata> CREATOR = new Creator<Passdata>() {
#Override
public Passdata createFromParcel(Parcel in) {
return new Passdata(in);
}
#Override
public Passdata[] newArray(int size) {
return new Passdata[size];
}
};
}
how can I add the object like this
do {
int audioTitle = audioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE);
int audioartist = audioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST);
int audioduration = audioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DURATION);
int audiodata = audioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
int audioalbum = audioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM);
int audioalbumid = audioCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID);
Passdata info = new Passdata();
info.setData(Uri.parse(audioCursor.getString(audiodata)));
info.setTitle(audioCursor.getString(audioTitle));
info.setDuration(audioCursor.getLong(audioduration));
// info.setArtist(audioCursor.getString(audioartist));
info.setAlbum(audioCursor.getString(audioalbum));
info.setAlbum_art(ContentUris.withAppendedId(albumArtUri, audioCursor.getLong(audioalbumid)));
audioList.add(info);
}
I am getting error in the place were I am creating the passdata object
how to fix this??
You don't have empty constructor in PassData class. Add this code:
public Passdata() {
}

When trying to pass a custom object from an activity to a fragment by using a bundle, I kept getting a null bundle when I tried to retrieve it in the fragment. I am using parcels since they are the only option for custom arraylists. Any help appreciated!
To show that my class is parcelable:
public class Exercise implements Parcelable{
private String mName;
private String mMuscleGroup;
private String mType;
private String mEquipment;
private float mWeight;
private int mReps;
private int mSet;
public Exercise(String name, String MuscleGroup, String type, String equipment, float weight, int reps, int set) {
mName = name;
mMuscleGroup = MuscleGroup;
mType = type;
mEquipment = equipment;
mWeight = weight;
mReps = reps;
mSet = set;
}
private Exercise(Parcel in) {
mName = in.readString();
mMuscleGroup = in.readString();
mType = in.readString();
mEquipment = in.readString();
mWeight = in.readFloat();
mReps = in.readInt();
mSet = in.readInt();
}
public static final Creator<Exercise> CREATOR = new Creator<Exercise>() {
#Override
public Exercise createFromParcel(Parcel in) {
return new Exercise(in);
}
#Override
public Exercise[] newArray(int size) {
return new Exercise[size];
}
};
public String getName() {
return mName;
}
public String getMuscleGroup() {
return mMuscleGroup;
}
public String getType() {
return mType;
}
public String getEquipment() {
return mEquipment;
}
public float getWeight() { return mWeight; }
public int getReps() { return mReps; }
public int getSet() { return mSet; }
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeString(mName);
parcel.writeString(mMuscleGroup);
parcel.writeString(mType);
parcel.writeString(mEquipment);
parcel.writeFloat(mWeight);
parcel.writeInt(mReps);
parcel.writeInt(mSet);
}
}

Activity I am passing bundle from:
#Override
protected void onPause() {
// send ArrayList of exercises to WorkoutsFragment
WorkoutsFragment workoutsFragment = new WorkoutsFragment();
Bundle bundle = new Bundle();
bundle.putSerializable("exercise", exercise);
workoutsFragment.setArguments(bundle);
// clear exercise ArrayList
super.onPause();
}
Fragment receiving bundle:
Bundle bundle = this.getArguments();
if(bundle != null) {
exercise = bundle.getParcelableArrayList("exercise");
}
You need to use bundle.putParcelableArrayList to put Parcelable list objects, not putSerializable
If the types don't match, you get null
I have an object with a couple of Strings, one int and another object which has 4 inner objects. All of them implementing Parcelable. In order to generate the boilerplate code, I used Parcelable plugin from Android studio.
Even though all the objects are parcelable, I'm getting the following error: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: AlbumTrackResponse
Here's how the POJOs look like:
Main object:
public class AlbumTrackResponse implements Parcelable {
private String id;
private String albumId;
private String position;
private String title;
private int rate;
private AllServices services;
public AllServices getServices() {
return services;
}
public void setServices(AllServices services) {
this.services = services;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getAlbumId() {
return albumId;
}
public void setAlbumId(String albumId) {
this.albumId = albumId;
}
public String getPosition() {
return position;
}
public void setPosition(String position) {
this.position = position;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public int getRate() {
return rate;
}
public void setRate(int rate) {
this.rate = rate;
}
protected AlbumTrackResponse(Parcel in) {
id = in.readString();
albumId = in.readString();
position = in.readString();
title = in.readString();
rate = in.readInt();
services = (AllServices) in.readValue(AllServices.class.getClassLoader());
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(id);
dest.writeString(albumId);
dest.writeString(position);
dest.writeString(title);
dest.writeInt(rate);
dest.writeValue(services);
}

Inner object with 4 objects
public class AllServices implements Parcelable {
private GigRevService gigrev;
private AppleService apple;
private GoogleService google;
private SpotifyService spotify;
protected AllServices(Parcel in) {
gigrev = (GigRevService) in.readValue(GigRevService.class.getClassLoader());

return new AllServices(in);
}
#Override

return new AllServices[size];
}
};
}
The inner objects from here contain just string items.
Here's how I pass the ArrayList to the bundle:
bundle.putParcelableArrayList(MediaPlayerService.TRACK_LIST, trackList);
I'm passing the items from an Activity to a Service. Any ideas why I'm getting this error?
EDIT: Implementation of service classes
public class GoogleService implements Parcelable {
private String name;
private String uri;
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
protected GoogleService(Parcel in) {
name = in.readString();
uri = in.readString();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeString(uri);
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<GoogleService> CREATOR = new Parcelable.Creator<GoogleService>() {
#Override
public GoogleService createFromParcel(Parcel in) {
return new GoogleService(in);
}
#Override
public GoogleService[] newArray(int size) {
return new GoogleService[size];
}
};
}
This looks extremly strange
this.services = in.readParcelable(getClass().getClassLoader());
You are pointing out to the wrong class loader. You have to use it like this
this.services = (AllServices)in.readParcelable(AllServices.class.getClassLoader());
Besides that, I am always using this site http://www.parcelabler.com/ to quickly generate my Parceables. Or you could use it like this
services = (AllServices) in.readValue(AllServices.class.getClassLoader());
Here:
protected AllServices(Parcel in) { this.gigrev = in.readParcelable(getClass().getClassLoader());
this.apple = in.readParcelable(getClass().getClassLoader());
this.google = in.readParcelable(getClass().getClassLoader());
this.spotify = in.readParcelable(getClass().getClassLoader()); }
Replace it with
protected AllServices(Parcel in) { this.gigrev = in.readParcelable(GigRevService.class.getClassLoader());
this.apple = in.readParcelable(AppleService.class.getClassLoader());
this.google = in.readParcelable(GoogleService.class.getClassLoader());
this.spotify = in.readParcelable(SpotifyService.class.getClassLoader()); }
And replace:
this.services = in.readParcelable(getClass().getClassLoader());
With:
this.services = in.readParcelable(AllServices.class.getClassLoader());
Also can you show the GoogleService etc classes? Each inner object's class must have a Parcelable creator also and implement the Parcelable interface as well.
In my Android app, I want to use Intent to pass a list of SingleGroup to another Activity where each SingleGroup object contains a list of SingleImage, here are class for SingleImage and SingleGroup:
public class SingleImage implements Parcelable{
public String name;
public int drawableId;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getDrawableId() {
return drawableId;
}
public void setDrawableId(int drawableId) {
this.drawableId = drawableId;
}
public SingleImage(String name, int drawableId)
{
this.name = name;
this.drawableId = drawableId;
}
public static final Parcelable.Creator<SingleImage> CREATOR
= new Parcelable.Creator<SingleImage>()
{
public SingleImage createFromParcel(Parcel in)
{
return new SingleImage(in);
}
public SingleImage[] newArray(int size)
{
return new SingleImage[size];
}
};
private SingleImage(Parcel in)
{
name = in.readString();
drawableId = in.readInt();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(drawableId);
}
}
Here is SingleGroup class:
public class SingleGroup implements Parcelable{
private static final String TAG = "SINGLEGROUP";
private ArrayList<SingleImage> images = new ArrayList<SingleImage>(0);
private String myTitle;
private String groupDesc;
public SingleGroup(String mTitle, String desc, ArrayList<SingleImage> imagesList) {
this.myTitle = mTitle;
this.groupDesc = desc;
this.images = imagesList;
}
public String getGroupDesc() {
return groupDesc;
}
public String getMyTitle() {
return myTitle;
}
public void setMyTitle(String myTitle) {
this.myTitle = myTitle;
}
public ArrayList<SingleImage> getImages() {
return images;
}
public void setImages(ArrayList<SingleImage> images) {
this.images = images;
}
public static final Parcelable.Creator<SingleGroup> CREATOR
= new Parcelable.Creator<SingleGroup>()
{
public SingleGroup createFromParcel(Parcel in)
{
return new SingleGroup(in);
}
public SingleGroup[] newArray(int size)
{
return new SingleGroup[size];
}
};
private SingleGroup(Parcel in)
{
myTitle = in.readString();
groupDesc = in.readString();
//problem maybe here
in.readTypedList(images,SingleImage.CREATOR);
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(myTitle);
dest.writeString(groupDesc);
//problem maybe here
dest.writeTypedList(images);
}
#Override
public String toString() {
String result = "myTitle "+myTitle+" desc "+ groupDesc + " imagesize "+images.size();
return result;
}
}
It works ok when calling to pass ArrayList<SingleImage> through Intent,
while when I called to pass ArrayLlist<SingleGroup> through Intent I got error:
Parcel android.os.Parcel#3c4c6743: Unmarshalling unknown type code
3211379 at offset 224
Any idea? Thanks in advance
---------------- Update ----------------
I have changed in.readTypedList(images, null); to in.readTypedList(images, SingleImage.CREATOR); but it still not working. same unmarshalling error
---------------- Problem Solved --------------
Thanks to Keita. The real problem is not actually listed in my code. When I passing the parcelable object, I should also include some other attributes which I missed.
Strongly recommend AS plugin Android Parcelable code generator
You must be pass SingleImage.CREATOR into method readTypedList instead of "null" value
private SingleGroup(Parcel in)
{
myTitle = in.readString();
groupDesc = in.readString();
//problem maybe here
in.readTypedList(images, SingleImage.CREATOR);
}
Try this one. That is what i always do and it work:
private SingleGroup(Parcel in)
{
myTitle = in.readString();
groupDesc = in.readString();
//problem maybe here
in.createTypedArrayList(SingleImage.CREATOR);
}
ArrayList is serialize. So try to this
public class SingleImage implements Serializable{
....
}
Refer this: ArrayList Android Documentation
I try to pass a News class to an activity, so I implemented the Parcelable interface. Inside News I have two classes implementing Parcelable too, Image and Date
The matter is that my News object at the end contains null for fields image and date.
Here my code:
News.java
public class News implements Parcelable {
public static final String TAG = "model_news";
private JSONObject object;
private int id;
private String type;
private String title;
private Boolean comment_disabled;
private String category_name;
private String url;
private Image images;
private Date date;
private Boolean is_video;
public News(JSONObject object) {
this.object = object;
try {
id = Integer.parseInt(object.getString("id"));
type = object.getString("type");
title = object.getString("title");
comment_disabled = object.getBoolean("comment_disabled");
category_name = object.getString("category_name");
url = object.getString("url");
if (!object.isNull("images")) {
images = new Image(object.getJSONObject("images"));
}
date = new Date(object.getJSONObject("date"));
is_video = object.getBoolean("is_video");
} catch (JSONException e) {
Log.e(TAG, e.getMessage());
}
}
protected News(Parcel in) {
id = in.readInt();
type = in.readString();
title = in.readString();
category_name = in.readString();
url = in.readString();
images = (Image) in.readParcelable(Image.class.getClassLoader());
date = (Date) in.readParcelable(Date.class.getClassLoader());
is_video = in.readByte() != 0;
comment_disabled = in.readByte() != 0;
}

dest.writeString(url);
dest.writeParcelable(images, flags);
dest.writeParcelable(date, flags);
dest.writeByte((byte) (is_video ? 1 : 0));
}
#Override

}
Image.java
public class Image implements Parcelable {
public static final String TAG = "model_image";
private JSONObject imageObj;
private JSONObject original;
private String source;
private int width;
private Drawable image;
public Image(JSONObject imageObj) {
this.imageObj = imageObj;
try {

};
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(source);
dest.writeInt(width);
}
}
what I'm doing wrong ?
There is mistake in the Parcelable implementation.
First of all parcelable implementation states that: the fields passed in News(Parcel in) Constructor should be written in the same sequence in writeToParcel() method. Thats called Marshalling and Unmarshalling.
Corrections:
Drawable cannot be passed a parameter in Parcelable.
News Parcelable implementation.
Missed some of the fields its just for your understanding.
public class News implements Parcelable {
public static final String TAG = "model_news";
private JSONObject object;
private int id;

Been trying to fix it for the pass day and getting no where all I know is that person parceable object in the challenge object are always null but they are not when I put them in the bundle.
Appreciate any input.
Those Integer type could be null or an int, you need to handle that situation properly.
For example I have utility functions like this :
static public Integer readInteger(Parcel in){
if(in.readInt() == 1){
return in.readInt();
}else{
return null;
}
}
static public void writeInteger(Integer value, Parcel out){
if(value != null){
out.writeInt(1);
out.writeInt(value);
}else{
out.writeInt(0);
}
}
First thing in the class Challenge you use Integer attributes and you parce "int" those are 2 diferents things.
Exemple of how i do things myself :
public Podcast(Parcel parcel) {
id = parcel.readLong();
title = parcel.readString();
subtitle = parcel.readString();
summary = parcel.readString();
duration = parcel.readString();
author = parcel.readString();
date = parcel.readString();
mp3 = parcel.readString();
podcastCategoryId = parcel.readLong();
}
#Override
public int describeContents() {
// not used
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeLong(id);
dest.writeString(title);
dest.writeString(subtitle);
dest.writeString(summary);
dest.writeString(duration);
dest.writeString(author);
dest.writeString(date);
dest.writeString(mp3);
dest.writeLong(podcastCategoryId);
}
public static Creator<Podcast> CREATOR = new Creator<Podcast>() {
public Podcast createFromParcel(Parcel parcel) {
return new Podcast(parcel);
}
public Podcast[] newArray(int size) {
return new Podcast[size];
}
};
#Override
public Person[] newArray(int size) {
return null;
}
You should create there an array of that size and return it.
#Override
public Person[] newArray(int size) {
return new Person[size];
}
Solved it was actually very simple, forgot song url when i was writing to the parcel. Any when i missed that write that was why i was getting the weird exception for person object. it was expecting a person object but was getting something else. 1 day wasted oh well :(
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeInt(challenger_id);
dest.writeInt(friend_id);
dest.writeString(artist_name);
**dest.writeString(song_name);**
dest.writeString(image_url);
dest.writeString(song_url);
dest.writeString(answer_url);
dest.writeInt(challenge_attempts_left);
dest.writeInt(answer);
dest.writeParcelable(person, flags);
dest.writeParcelable(friend, flags);
}
