OnPost Execute method how can I pass image from one Fragment to other activity. Able to pass the image from drawable folder using Bundle

OnPost Execute method how can I pass image from one Fragment to other activity. Able to pass the image from drawable folder using Bundle. Loding product details from server and able to other information except Image to other Activity.

Limiting ListView with AsyncTask Using ArrayAdapter

I am developing app just like YOUTUBE. I am getting data from the server and showing it in listview. Because data is too big so i want to restrict list view to 5 items and then when I scroll down to the bottom of listview it should add 5 more item.
I am calling ASyncTask from fragment
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
LayoutInflater layoutInflater = LayoutInflater.from(getContext());
view = layoutInflater.inflate(R.layout.tab_fragment_2, container, false);
listView = (ListView) view.findViewById(R.id.myList);
New.jsonAsyncTask.execute("my url select_video.php?");
}
Now I have separate JsonAsyncTask Class because I am calling it from 3 fragments just like above mentioned way..
public class JSONAsyncTask extends AsyncTask<String, String, List<SetDatails>> {
ListView listView1;
Context context1;
List<SetDatails> videoLiast1;
private static int tab_id;
public JSONAsyncTask(ListView listView, List<SetDatails> videoLiast,Context context,int id) {
this.listView1 = listView;
this.context1 = context;
this.videoLiast1 = videoLiast;
tab_id=id;
}
#Override
protected List<SetDatails> doInBackground(String... params) {
HttpURLConnection connection = null;
BufferedReader myReader = null;
try {
URL url = new URL(params[0]);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
InputStream myInputStream = connection.getInputStream();
myReader = new BufferedReader(new InputStreamReader(myInputStream));
StringBuffer buffer = new StringBuffer();
String line = "";
while ((line = myReader.readLine()) != null) {
buffer.append(line);
}
String Json_data = buffer.toString();
videoLiast1 = new ArrayList<>();
JSONObject parentObj = new JSONObject(Json_data);
JSONArray dataArray = parentObj.getJSONArray("data");
JSONObject tabObject = dataArray.getJSONObject(tab_id);
JSONArray videoArray = tabObject.getJSONArray("videos");
for (int i = 0; i < videoArray.length(); i++) {
int len=dataArray.length();
SetDatails setDatails = new SetDatails();
JSONObject arrayChild = videoArray.getJSONObject(i);
String vid_ID = arrayChild.getString("id");
setDatails.setVidID(vid_ID);
String movie_title = arrayChild.getString("name");
setDatails.setTitle(movie_title);
String movie_catagory = arrayChild.getString("category_name");
setDatails.setGenre(movie_catagory);
videoLiast1.add(setDatails);
}
return videoLiast1;
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
} catch (Throwable throwable) {
throwable.printStackTrace();
} finally {
if (connection != null) {
connection.disconnect();
}
try {
if (myReader != null) {
myReader.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
}
protected void onPostExecute(List<SetDatails> videoList) {
super.onPostExecute(videoList);
if(videoList!=null) {
try {
MyListAdapter myListAdapter = new MyListAdapter(context1, videoList);
listView1.setAdapter(myListAdapter);
}catch (Exception ex)
{
ex.printStackTrace();
}
}
}
}
I have created an Array adapter to fill list view.
public class MyListAdapter extends ArrayAdapter<SetDatails>{
public static int count =5;
List<SetDatails> videoList;
MyListAdapter(Context context,List<SetDatails> object){
super(context,R.layout.tab2_bookchilds,object);
videoList = object;
}
/**
* {#inheritDoc}
*/
#Override
public int getCount() {
return super.getCount();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater=LayoutInflater.from(getContext());
View view = layoutInflater.inflate(R.layout.tab2_bookchilds, parent, false);
TextView title = (TextView)view.findViewById(R.id.txt_title);
title.setText(videoList.get(position).getTitle());
ImageView imgV_Thumbnail = (ImageView) view.findViewById(R.id.imgV_thumbnail);
Picasso.with(getContext())
.load(videoList.get(position).getThumbnail())
.error(R.drawable.icon_white)
.into(imgV_Thumbnail);
return view;
}
}
I have searched a lot and many people suggest getCount() method although I tried a lot to use this method but don't know how to do that.
Please guys help me because my app is ready to upload but I can't solve this one issue.

ListView does not show any data, getCount() returns 0, getView() never calls

I am trying to fetch data using AsyncTask & displaying into a ListView. It never calls getView(), I checked getCount() return always 0.

Please help.

You are not setting data retrieved from AsyncTask to adapter.
Add this method to your adapter class:
public void setItems(SourceObject[] items) {
this.objects = new ArrayList<SourceObject>();
for(SourceObject item : items){
this.objects.add(item);
}
this.notifyDataSetChanged();
}
And change onPostExecute of AsyncTask to:
#Override
protected void onPostExecute(SourceObject[] strings) {
adapter.setItems(strings);
super.onPostExecute(strings);
}

Populating Listview from ArrayList which in turn is populated by .txt file

i am working on this Android application which firstly downloads a .txt file from internet then populates the arraylist and in the end listview. The problem is that the Listview doesn't seem to populate despite that my file downloading and reading is everything ok since i have tested it with a TOAST.
Here is my code
Downloading File and Reading with AsyncTask
public class DownloadFile extends AsyncTask<String, Void, String> {
String filenamelist=TEST_FILE_NAME;
#Override
protected String doInBackground(String... params) {
//Here i download the file
} catch (Exception e) {
e.printStackTrace();
}
return "Executed";
}
#Override
protected void onPostExecute(String result) {
try {
InputStream instream = new FileInputStream(new File(getCacheDir(), filenamelist));
InputStreamReader inputreader = new InputStreamReader(instream);
BufferedReader bReader = new BufferedReader(inputreader);
String key,value = null;
do{
key = bReader.readLine();
if(key != null)
value = bReader.readLine();
//channelname is the ArrayList
channelname.add(key);
channelmaps.put(key,value);
} while (key != null && value != null);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Declaration of ArrayList
ArrayList<String> channelname = new ArrayList<String>();
Listview
final ListView listView = (ListView) findViewById(android.R.id.list);
channelname.removeAll(Collections.singleton(null));
ChannelAdapter cAdapter = new ChannelAdapter(this, channelname);
listView.setAdapter(cAdapter);
ChannelAdapter class
private class ChannelAdapter extends ArrayAdapter<String>
{
ArrayList<String> channelname;
public ChannelAdapter(Context context, ArrayList<String> channelname)
{
super (context, R.layout.activity_list_channels, channelname);
this.channelname = channelname;
}
public View getView(int position, View convertView, ViewGroup parent)
{
try
{
if(convertView==null)
{
LayoutInflater inflater = getLayoutInflater();
convertView = inflater.inflate(R.layout.mylistchannel,parent, false);
}
String name = getItem(position);
TextView txtview = (TextView) convertView.findViewById(R.id.Channelname);
txtview.setText(name);
return convertView;
}
catch(Exception e)
{
}
return null;
}
#Override
public int getCount()
{
return channelname.size();
}
#Override
public String getItem(int position)
{
return channelname.get(position);
}
#Override
public long getItemId(int position)
{
return 0;
}
}
So what's the problem with my code? Why isn't the listview populated?

You should do
cAdapter.notifyDataSetChanged();
after the cycle in which you've read all the items from the file;

Insert Image from an URL inside a ListView

I would like to know if it is possible to load an image inside a ListView directly from the web, when the URL is stocked inside a json.
Edit : Solved, It is possible to use an AsyncTask
public class ParseImage extends AsyncTask<Object, String, Drawable> {
private ProgressBar pd;
private ImageView imv;
private int position;
public ParseImage(int position, ImageView imv, ProgressBar pd2) {
this.position = position;
this.imv = imv;
this.pd = pd2;
}
#Override
public Drawable doInBackground(Object... params) {
Drawable d = null;
try {
d = Drawable.createFromStream(
(InputStream) new URL(list.get(position).get("Cover"))
.getContent(), "src");
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return d;
}
public void onPostExecute(Drawable result) {
if (result != null && imv != null) {
pd.setVisibility(View.INVISIBLE);
imv.setImageDrawable(result);
}
}
}
}

You need to create your own custom Listview to show more than a String.Here is a piece of code you can refer:
MovieAdaptor.java:
public class MovieAdaptor extends ArrayAdapter<Movie> {
Context context;
int layoutResourceId;
ArrayList<Movie> movieArrayList = new ArrayList<Movie>();
public MovieAdaptor(Context context, int layoutResourceId, ArrayList<Movie> movies) {
super(context, layoutResourceId, movies);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.movieArrayList = movies;
}
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
ContactHolder holder = null;
if (row == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ContactHolder();
holder.thumbnail = (ImageView) row.findViewById(R.id.imageThumbnail);
holder.title = (TextView) row.findViewById(R.id.MovieTitle);
holder.synopsis = (TextView) row.findViewById(R.id.synopsis);
row.setTag(holder);
} else {
holder = (ContactHolder) row.getTag();
}
holder.title.setText(movieArrayList.get(position).title);
holder.synopsis.setText(movieArrayList.get(position).synopsis);
newAsyncDownloadImage(holder.thumbnail).execute(movieArrayList.get(position).posters.get("thumbnail"));
return row;
}
static class ContactHolder {
ImageView thumbnail;
TextView title;
TextView synopsis;
}
}
Activity.class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
moviesListView = (ListView) findViewById(R.id.list_movies);
moviesListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position > HEADER) {
Intent intent = new Intent(getBaseContext(), MovieActivity.class);
intent.putExtra(MOVIE_OBJECT, movieArrayList.get(position - 1));
startActivity(intent);
}
}
});
View header = (View) getLayoutInflater().inflate(R.layout.listview_row_header, null);
moviesListView.addHeaderView(header);
movieAdaptor = new MovieAdaptor(this, R.layout.listview_row_item, movieArrayList);
moviesListView.setAdapter(movieAdaptor);
AsyncDownloadImage.java:
public class AsyncDownloadImage extends AsyncTask<Object, Object, Object> {
ImageView iv;
private HttpURLConnection connection;
private InputStream is;
private Bitmap bitmap;
public AsyncDownloadImage(ImageView mImageView) {
iv = mImageView;
}
#Override
protected Object doInBackground(Object... params) {
URL url;
try {
url = new URL((String) params[0]);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
is = connection.getInputStream();
bitmap = BitmapFactory.decodeStream(is);
is.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (is != null) {
is.close();
}
if (connection != null) {
connection.disconnect();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return bitmap;
}
#Override
protected void onPostExecute(Object result) {
super.onPostExecute(result);
if (null != result) {
iv.setImageBitmap((Bitmap) result);
} else {
iv.setBackgroundResource(R.drawable.ic_launcher);
}
}
}
}

Can you send the return of
JSONfunction.getJSONfromURL("http://colmarmagazine.ctai.fr/issues.php");
Please ?
I think it's a bad parting ! Because you have :
Unable to decode stream: java.io.FileNotFoundException: /http:/colmarmagazine.ctai.fr/content/numerodemo/numerodemo.png: open failed: ENOENT (No such file or directory)
and a "/" too much in the url for your cover !
