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() {
}

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);
}

now send this to new activity in intent like this

Now get the object in the new activity like this

public class NewActivity extends Activity {

dataGetter= (UploadDataGetter) intent.getSerializableExtra("data");
Log.d("NewActivity","ID: "+dataGetter.getId());
}
}
}
Good day. I need to implement parcelable in Model class.Currently it is Serializable. for now only setdate and set title if thare If any one can help. please edit code.

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());
What I want is to pass a list of list from one activity to another. Here is my approach.
Feeditem.java
public class FeedItem implements Parcelable {
private String id,status, image, timeStamp, url;
private ArrayList<CommentItem> commentItems;
public FeedItem() {
}
protected FeedItem(Parcel in) {
id = in.readString();
status = in.readString();
image = in.readString();
timeStamp = in.readString();
url = in.readString();
if(commentItems!=null) {
in.createTypedArrayList(CommentItem.CREATOR);
}
}
public static final Creator<FeedItem> CREATOR = new Creator<FeedItem>() {
#Override
public FeedItem createFromParcel(Parcel in) {
return new FeedItem(in);
}
#Override
public FeedItem[] newArray(int size) {
return new FeedItem[size];
}
};
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getImge() {
return image;
}
public void setImge(String image) {
this.image = image;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(String timeStamp) {
this.timeStamp = timeStamp;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public ArrayList<CommentItem> getCommentItems() {
return commentItems;
}
public void setCommentItems(ArrayList<CommentItem> commentItems)
{
this.commentItems=commentItems;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(id);
dest.writeString(status);
dest.writeString(image);
dest.writeString(timeStamp);
dest.writeString(url);
dest.writeTypedList(commentItems);
}}
CommentItem.java
public class CommentItem implements Parcelable{
private String id,comment, from, timeStamp;
public CommentItem() {
}
protected CommentItem(Parcel in) {
id = in.readString();
comment = in.readString();
from = in.readString();
timeStamp = in.readString();
}
public static final Creator<CommentItem> CREATOR = new Creator<CommentItem>() {
#Override

public void setComment(String comment) {

}
public String getTimeStamp() {

public void setTimeStamp(String timeStamp) {
this.timeStamp = timeStamp;
}
#Override

#Override

dest.writeString(id);
dest.writeString(comment);

dest.writeString(timeStamp);
}}
ReceivingActivity.java
ArrayList<CommentItem> commentItems;
FeedItem feedItem;
commentItems=new ArrayList<>();
Bundle bundle=getIntent().getExtras();
feedItem=bundle.getParcelable("status");
if(feedItem.getCommentItems()!=null) { //help here
commentItems = feedItem.getCommentItems();
}
SendingActivity.java
Button getComments=(Button)convertView.findViewById(R.id.commentsbutton);
getComments.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(activity, CommentActivity.class);
Bundle bundle = new Bundle();
bundle.putParcelable("status", item); //item is feeditem
i.putExtras(bundle);
activity.startActivity(i);
}
});
I am able to get all the attributes of the feeditem except the list which is giving me null in the receiving activity. Could someone please help me out with this. Thanks in advance.
I think the problem is that you're only reading in the list if it is already non-null:
if(commentItems!=null) {
in.createTypedArrayList(CommentItem.CREATOR);
}
If it's null, which it will be at that point, it doesn't get set. Just remove the non-null check and I think it will work.
commentItems = in.createTypedArrayList(CommentItem.CREATOR);
