I have a gridview which should show emojies that are retrieved from the server as urls, I was able to retrieve the urls and put it inside an arraylist, however using the gridview adapter, no images show at all, I've tried debugging by handcoding the url outside the for loop and it showed the image, which means that nothing is wrong with my adapter, also when I try to hardcode the url inside the for loop like arraylist.add("the url") no image appears, here's my code, please advise why the images are not showing, appreciate your assistance

Im new on java and im doing a app for finish my university. This app have a SearchView filtering on a ListView getting data from a JSON. Im almost finishing that but im stuck after the filter part.
After input on the SearchBar and filter returns the result I cant open a new intent getting the ID from the JSON. I only can open the intent using the position ListView number (that doesn't work for my necessity because of filter process).
The image below shows exactly the issue:

So my necessity is: Open a intent using the ID stored on the JSON for avoid the issue of changing position ID after filter result.
I dont have any idea how I fix this.
Bean:
public class Model {
private String description;
private int id;
public Model(int id, String description) {
this.setId(id);
this.setDescription(description);

this.id = id;

JSON:
{ "locais": [{
"id": "1",
"description": "Text A"
}, {
"id": "2",
"description": "Text B"
}]}
use int a = modelArrayList.get(position).getId() instead. So you will get id from JSON
You need to use that intent in ListViewAdapter
Hope its works fine
I am fetching data from a server in a recycler view.In a layout file I have an EditText field on top and below it I have a recycler view.
I want to filter data based on what I have written in EditText field.
My problem is as I start typing in EditText field it shows no data in recycler and as I removes everything in EditText field it shows everything.
Why it is happening even if I have data present in recycler view with the same name I have entered in EditText field.

Someone please let me know what I am doing wrong. Any help would be appreciated.

Move this code outside the for Loop
adapter.setFilter(filterBooks);
Because adapter is calling set Filter after each iteration.
Also I would request you to move network request to Activity instead of Fragment using interface.
for(LoadHomeBooks books: list){
String name = books.getbName().toLowerCase();
if(name.contains(s)){
filterBooks.add(books);
}
adapter.setFilter(filterBooks); //Place this line outside forloop
}
I am making a news feed where I retrieve Facebook posts from a specific Facebook page. I retrieve those posts with help of the Facebook Graph API. I have a FeedItem which has an ID (int). The ID is also used to check which item is at the current position (Recyclerview).
The problem is that Facebook gives the posts a String ID. I have no idea how I can possibly convert this so that it will work with my application.

As I said; I have no idea how to handle this and I figured someone here would maybe have an idea on how to convert this, so that I can use the String that the graph api gives me, and use it as an integer.
If the id is all numeric, you should be able to do this: int id = Integer.valueOf(facebookId)
If you have an undescore you can try this:
public int getIdFromString(String postId) {
String finalId;
while (postId.indexOf("_") > 0) {
finalId = postId.substring(0, postId.indexOf("_"));
postId = finalId.concat(postId.substring(postId.indexOf("_") + 1));
}
return Integer.valueOf(postId);
}
If the value is numeric and you want an integer object, do
Integer id = Integer.valueOf(facebookId);
If you want the primitive type int, then do
int id = Integer.parseInt(facebookId);
or
int id = Integer.valueOf(facebookId);

I am using this library and loading images by
first creating the Display options object by
DisplayImageOptions builder = new DisplayImageOptions.Builder()
.cacheOnDisk(true)
.showImageOnLoading(R.drawable.empty_photo)
.showImageForEmptyUri(R.drawable.empty_photo)
.build();
Then initialze the image loader by
ImageLoader imageLoader = ImageLoader.getInstance();
and load images by
imageLoader.displayImage(url, imageView, builder);
Hope this helps..
also add this to you gradle
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
Refer this first
EDIT: Add this to onCreate() of activity
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this)
...
.build();
ImageLoader.getInstance().init(config);
or this
ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(Activity.this));
Add getter and setter methods for your Image like
public String getImageUrl() {
return imageUrl;
}
public void setImageUrl(String imgUrl) {
imageUrl= imgUrl;
}
Add this code in your adapter class after adding Picasso library to your project:
String imageUrl = movieData.get(position).getImageUrl();
Picasso.with(getContext())
.load(imageUrl)
.into(holder.movieImage, new com.squareup.picasso.Callback() {
#Override
public void onSuccess() {
}
#Override
public void onError() {
}
});
I write client for kaltura media platform.
I have an activity "Video". In this activity I must display list of video with thumbnails
First of all, I download list of videos using kaltura api, and this works fine. Every video entry have a field thumbnailUrl, which point out to thumbnail for video.
When I download this thumbnails for videos, it's(thumbnails) downloads in incorrect order, some thumbnails not downloaded, some thumbnails repeated for other video, and some not downloaded.
This is code of callback if downloadind videos:
private void handleFetchvideoListTask(List<VideoObject> videoObjects){
LinearLayout videoListProgressBarContainer = (LinearLayout)mActivity.findViewById(R.id.videoListProgressBarContainer);
LinearLayout videoListViewContainer = (LinearLayout)mActivity.findViewById(R.id.videoListViewContainer);
videoListProgressBarContainer.setVisibility(View.GONE);
videoListViewContainer.setVisibility(View.VISIBLE);
ListView listView = (ListView)videoListViewContainer.findViewById(R.id.videoListView);
VideoListAdapter adapter = new VideoListAdapter((LayoutInflater) mActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE));
adapter.setList(videoObjects);
listView.setAdapter(adapter);
DownloadThumbnailsTask task = new DownloadThumbnailsTask(videoObjects, adapter);
task.execute();
}
This is code of DownloadThumbnailsTask:
public class DownloadThumbnailsTask extends AsyncTask<List<VideoObject>, VideoObject, Void>{
private List<VideoObject> videoObjectList = null;
private List<VideoObject> toProcess = null;
private VideoListAdapter adapter = null;
public DownloadThumbnailsTask(List<VideoObject> videoObjectList, VideoListAdapter adapter){
this.videoObjectList = videoObjectList;
this.toProcess = new ArrayList<VideoObject>(videoObjectList);
this.adapter = adapter;
}
#Override
protected Void doInBackground(List<VideoObject>... lists) {
for(int i=0; i<toProcess.size(); i++){
VideoObject item = videoObjectList.get(i);
String urldisplay = item.getThumbnailUrl();
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
item.setThumbnail(mIcon11);
mIcon11 = null;
publishProgress(item);
}
return null;
}
#Override
protected void onProgressUpdate(VideoObject... values) {
if(values != null && values.length > 0){
VideoObject item = values[0];
videoObjectList.remove(item);
videoObjectList.add(item);
adapter.setList(videoObjectList);
adapter.notifyDataSetChanged();
}
}
#Override
protected void onPostExecute(Void aVoid) {
this.toProcess.clear();
this.toProcess = null;
}
}
This is code of adapter:
public class VideoListAdapter extends BaseAdapter {
private List<VideoObject> list;
private LayoutInflater layoutInflater;
public VideoListAdapter(LayoutInflater layoutInflater){
this.layoutInflater = layoutInflater;
}
#Override
public int getCount() {
return list.size();
}
#Override
public Object getItem(int i) {
return list.get(i);
}
#Override
public long getItemId(int i) {
return list.get(i).getId();
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
if(view == null){
view = layoutInflater.inflate(R.layout.list_item_video, viewGroup, false);
}
ViewHolder viewHolder = new ViewHolder(view);
view.setTag(viewHolder);
VideoObject item = getVideoObjectItem(i);
viewHolder.duration.setText(item.getFormattedDuration());
viewHolder.title.setText(item.getName());
if(item.getThumbnail() != null){
viewHolder.thumbnail.setImageBitmap(item.getThumbnail());
}
return view;
}
private VideoObject getVideoObjectItem(int position){
return (VideoObject) getItem(position);
}
public List<VideoObject> getList() {
return list;
}
public void setList(List<VideoObject> list) {
this.list = list;
}
public static class ViewHolder {
public final ImageView thumbnail;
public final TextView title;
public final TextView duration;
public ViewHolder(View view) {
this.thumbnail = (ImageView)view.findViewById(R.id.imgVideoThumbnail);
this.title = (TextView)view.findViewById(R.id.txtVideoName);
this.duration = (TextView)view.findViewById(R.id.txtVideoDuration);
}
}
}
And this is result of my code:
I noticed two things:
Inside doInBackground you are waiting
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
to complete before downloading the next image.
Try this:
protected Void doInBackground(List<VideoObject>... lists) {
for(final int i=0; i<toProcess.size(); i++){
try {
new Thread(){
#Override
public void run() {
VideoObject item = videoObjectList.get(i);
String urldisplay = item.getThumbnailUrl();
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
item.setThumbnail(mIcon11);
publishProgress(item);
}
}.start();
} catch (Exception e) {
Log.e("Error", e.getMessage());
}
}
return null;
}
#Override
protected void onProgressUpdate(VideoObject... values) {
adapter.notifyDataSetChanged();
}
I think this two lines is the problem:
videoObjectList.remove(item);
videoObjectList.add(item);
You're removing an item and adding again at the bottom. Just call notifyDataSetChanged after setting the bitmap.
Inside getView you're creating a new ViewHolder every time.
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
ViewHolder viewHolder;
if(view == null){
view = layoutInflater.inflate(R.layout.list_item_video, viewGroup, false);
viewHolder = new ViewHolder(view);
view.setTag(viewHolder);
}else{
viewHolder = view.getTag();
}
VideoObject item = getVideoObjectItem(i);
viewHolder.duration.setText(item.getFormattedDuration());
viewHolder.title.setText(item.getName());
if(item.getThumbnail() != null){
viewHolder.thumbnail.setImageBitmap(item.getThumbnail());
}
return view;
}
Do you get anything in your logcat? Maybe opening the stream or decoding fails. Are the images large?
