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.
MainActivity.java
Document document = Jsoup.connect("http://feeds.bbci.co.uk/urdu/rss.xml").ignoreHttpErrors(true).get();
Elements itemElements = document.getElementsByTag("item");
for (int i = 0; i < itemElements.size(); i++) {
Element item = itemElements.get(i);
NewsItem newsItem = new NewsItem();
newsItem.setDate(item.child(4).text());
newsItem.setTitle(item.child(0).text());
newsItemsList.add(newsItem);
}
} catch (IOException e) {
e.printStackTrace();
}
runOnUiThread(new Runnable() {
#Override
public void run() {
adapter = new NewsAdaptor(Main2Activity.this,
newsItemsList);
lvRss.setAdapter(adapter);
}
});
return null;
}
NewsItem.java //model class
public class NewsItem implements Serializable {
String imagePath;
String title;
String link;
String date;
public NewsItem () {
}
public String getImagePath () {
return imagePath;
}
public void setImagePath ( String imagePath ) {
this.imagePath = imagePath;
}
public String getTitle () {
return title;
}
public void setTitle ( String title ) {
this.title = title;
}
public String getLink () {
return link;
}
public void setLink ( String link ) {
this.link = link;
}
public String getDate () {
return date;
}
public void setDate ( String date ) {
this.date = date;
}
NewsAdapter.java
public class NewsAdaptor extends BaseAdapter {
private int textSize;
TextView tvtitle;
private int color;
Context context;
public NewsAdaptor ( Context context, ArrayList <NewsItem> newsList ) {
this.context = context;
this.newsList = newsList;
this.color = Color.RED;
}
ArrayList<NewsItem> newsList;
#Override
public int getCount () {
return newsList.size();
}
#Override
public Object getItem ( int position ) {
return newsList.get(position);
}
#Override
public long getItemId ( int position ) {
return 0;
}
#Override
public View getView ( int position, View convertView, ViewGroup parent ) {
if (convertView == null){
convertView=View.inflate(context, R.layout.newsitemlist_layout,null);
}
NewsItem currentNews = newsList.get(position);
ImageView iv1 = (ImageView) convertView.findViewById(R.id.mainimg);
TextView tvdate = (TextView) convertView.findViewById(R.id.pubDateid);
Picasso.with(context).load(currentNews.getImagePath()).placeholder(R.drawable.expressimg).into(iv1);
tvdate.setText(currentNews.getDate());
tvtitle = (TextView) convertView.findViewById(R.id.textView1id);
tvtitle.setText(currentNews.getTitle());
tvtitle.setTextColor(color);
return convertView;
}
public void setTextColor(int color) {
this.color = color;
}
Check this Parcelable NewsItem:
public class NewsItem implements Parcelable {
String imagePath;
String title;
String link;
String date;
public NewsItem() {
}
protected NewsItem(Parcel in) {
imagePath = in.readString();
title = in.readString();
link = in.readString();
date = in.readString();
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(imagePath);
dest.writeString(title);
dest.writeString(link);
dest.writeString(date);
}
#Override
public int describeContents() {
return 0;
}
public static final Creator<NewsItem> CREATOR = new Creator<NewsItem>() {
#Override
public NewsItem createFromParcel(Parcel in) {
return new NewsItem(in);
}
#Override
public NewsItem[] newArray(int size) {
return new NewsItem[size];
}
};
public String getImagePath() {
return imagePath;
}
public void setImagePath(String imagePath) {
this.imagePath = imagePath;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getLink() {
return link;
}
public void setLink(String link) {
this.link = link;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
}

I have an autocompletetextview. I am getting results from an API and sending to the adapter on textchanged.
Here is the adapter.
public class ProductSearchAdapter extends BaseAdapter implements Filterable {
private Context context;
private ArrayList<ProductListModel> originalList;
private ArrayList<ProductListModel> suggestions = new ArrayList<>();
private Filter filter = new CustomFilter();
public ProductSearchAdapter(Context context, ArrayList<ProductListModel> originalList) {
this.context = context;
this.originalList = originalList;
}
#Override
public int getCount() {
return suggestions.size(); // Return the size of the suggestions list.
}
#Override
public Object getItem(int position) {
return originalList.get(position).getName();
}
#Override
public long getItemId(int position) {
return 0;
}
/**
* This is where you inflate the layout and also where you set what you want to display.
* Here we also implement a View Holder in order to recycle the views.
*/
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(context);
ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.product_search_row, parent, false);
holder = new ViewHolder();
holder.textViewProductName = (TextView) convertView.findViewById(R.id.textViewProductName);
holder.imageViewProductImage = (ImageView) convertView.findViewById(R.id.imageViewProductImage);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.textViewProductName.setText(originalList.get(position).getName());
Picasso.with(context)
.load(originalList.get(position).getImagesSmall().get(0).getSrc())
.into(holder.imageViewProductImage);
return convertView;
}
#Override
public Filter getFilter() {
return filter;
}
private static class ViewHolder {
ImageView imageViewProductImage;
TextView textViewProductName;
}
/**
* Our Custom Filter Class.
*/
private class CustomFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
suggestions.clear();
if (originalList != null && constraint != null) { // Check if the Original List and Constraint aren't null.
for (int i = 0; i < originalList.size(); i++) {
if (originalList.get(i).getName().toLowerCase().contains(constraint)) { // Compare item in original list if it contains constraints.
suggestions.add(originalList.get(i)); // If TRUE add item in Suggestions.
}
}
}
FilterResults results = new FilterResults(); // Create new Filter Results and return this to publishResults;
results.values = suggestions;
results.count = suggestions.size();
return results;
}
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
}
Now the problem is the dropdown is not showing up. Whereas if I try the same autocompletetextview with array adapter, its showing up.
Here is the activity part I am calling the api from:
autoCompleteTextViewSearch.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
if (charSequence.toString().length() > 0) {
hitSearchAPI(charSequence.toString());
}
}
#Override
public void afterTextChanged(Editable editable) {
}
});
On API response:
final GsonBuilder gsonBuilder = new GsonBuilder();
final Gson gson = gsonBuilder.create();
productList = gson.fromJson(responseString, ProductListModel[].class);
arrayListProducts = new ArrayList<ProductListModel>(Arrays.asList(productList));
productsSearchAdapter = new ProductSearchAdapter(MainActivity.this, arrayListProducts);
autoCompleteTextViewSearch.setThreshold(1);
autoCompleteTextViewSearch.setAdapter(productsSearchAdapter);
Same textview working with array adapter but not with custom adapter.

You need to add toString() method to your model so the AutoCompleteTextView can compare between the typed String and the returned value.
if you are looking by name the toString() needs to return it :
#Override
public String toString() {
return name ;
}
}

Check if the server response is different then null before you do a enhanced for like this:
if(singleBlogPosts!= null) {
for (SingleBlogPosts posts : singleBlogPosts){
Log.d("AnotherSingleView","Please check RESPONSE: "+response.body().toString());
blogTitle.setText(posts.getBlogTitle());
blogSub.setText(posts.getBlogSubtitle());
blogContent.setText(posts.getBlogContent());
// Glide.with(AnotherSingleView.this).load(singlepost.getBlogMedimg()).into(blogPic);
}
}
you question was list iterator,but we can`t see you list use on anywhere,i guess you may be use recyclerView on you data has not get,because get data was asynchronous.try to use data if you can sure it is existing.
In the below android activity, trying to display data in a view pager and it is working as expected.

DealerInventory dealerInventory = new DealerInventory();
dealerInventory = dealerInventory.getLastModifiedInventory(this, id.getItemId(), dealer.getId());
if (dealerInventory != null) {
if (dealerInventory.getQuantity() >= 0) {
id.setParentSalesPointLastStock(String.valueOf(dealerInventory.getQuantity()));
id.setParentSalesPointLastStockTakingDate(dealerInventory.getStockTakingDate());
}
} else {
id.setParentSalesPointLastStock(UiConstants.NA);
id.setParentSalesPointLastStockTakingDate(UiConstants.NA);
}
inventories.add(id); // do this
}
return inventories; // you are not assigning value anywhere;
}
You are not assigning value to the inventories in getInventoriesByItemDetails. I think you should add item through inventories.add(id);
Check it , Hope this help

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) {

public void setFrom(String from) {

return comment;
}
public void setComment(String comment) {
this.comment = comment;
}
public String getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(String timeStamp) {

}
#Override

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);
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);
}
