Convert gdata feed to xml - Youtube Playlist to ANdroid Listview

Convert gdata feed to xml - Youtube Playlist to ANdroid Listview - android

I am following this code to create a custom list view.
It uses an XML file to parse objects and show them in Listview
I was wondering can I use the same example to show Videos Titles and Duration of a Youtube Playlist.
I have gone though Youtube API and GDATA but I can't find out how to get raw xml link which I can use with above example code
Any help guys?

Heres a class I've used in one of my previous projects. This puts the first video as the "main" one, displays the time and title, and then adds all the rest of the videos to a layout.
public class Videos extends Activity {
ImageView mainThumb;
TextView mainTitle;
TextView mainTime;
LinearLayout videos;
ArrayList<String> links;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.videos);
new ParseVideoDataTask().execute();
mainThumb = (ImageView) findViewById(R.id.mainThumb);
mainTitle = (TextView) findViewById(R.id.mainTitle);
mainTime = (TextView) findViewById(R.id.mainTime);
videos = (LinearLayout) findViewById(R.id.videos);
}
private class ParseVideoDataTask extends AsyncTask<String, String, String> {
int count = 0;
#Override
protected String doInBackground(String... params) {
URL jsonURL;
URLConnection jc;
links = new ArrayList<String>();
try {
jsonURL = new URL("http://gdata.youtube.com/feeds/api/playlists/" +
YOUR PLAYLIST ID +
"?v=2&alt=jsonc");
jc = jsonURL.openConnection();
InputStream is = jc.getInputStream();
String jsonTxt = IOUtils.toString(is);
JSONObject jj = new JSONObject(jsonTxt);
JSONObject jdata = jj.getJSONObject("data");
JSONArray aitems = jdata.getJSONArray("items");
for (int i=0;i<aitems.length();i++) {
JSONObject item = aitems.getJSONObject(i);
JSONObject video = item.getJSONObject("video");
String title = video.getString("title");
JSONObject player = video.getJSONObject("player");
String link = player.getString("default");
String length = video.getString("duration");
JSONObject thumbnail = video.getJSONObject("thumbnail");
String thumbnailUrl = thumbnail.getString("hqDefault")
String[] deets = new String[4];
deets[0] = title;
deets[1] = thumbnailUrl;
deets[2] = length;
links.add(link);
publishProgress(deets);
}
} catch (MalformedURLException e) {
e.printStackTrace();

e.printStackTrace();

return null;
}

Playing videos using textureview inside recyclerview with cardview in android

I done video playing inside recyclerview with cardview using sdcard path location. Also check sdcard not available then fetch recorded videos from internal memory. Its perfectly working in Lava iris x8 device, but in Samsung J5 and Samsung Note 2 only odd numbers(1,3,5,7) videos are playing not even(2,4,6,8) videos are playing and getting dialog like "Can't play this video" when scrolling and getting position of even(2,4,6,8) numbers of video. I am not able to know what is the problem? Below is my whole code about display and play video inside recyclerview and cardview in android.

Circular imageview dissappears in listview after fling

Im generating a feed full of images (similar to instagram post) using Glide for loading images and user's profile picture. After i get the data from server, i load the Url's of images inside the listitem. Initally All items are being loaded properly.
The issue is that when i fast scroll the listview, user profile picture dissappears and that view doesnt respond to onClick Events. Please explain why this happens and how can i resolve this?

When loading multiple images there is always caching problem when using Async Tasks. I recommend an open source library Picasso. It will load the images and cache it. After that most probably, your fast scroll problem will solve.
The cause can also be the size of the images being received. Picasso has methods by which you can resize the image before putting it onto the image view

How to loop execution of AsyncTask with an array of params

I'm new in Android programming.
I created classes of web objects each class has 3 RSS URLs to be parsed. I loop an array of this objects to operate on each one the AsyncTask Executer. Every time I do that different errors appear and the UI freezes. I can't find what's wrong. Then I use custom adapter to display the UI but program don't even reach to that code. Please help me finding what's wrong with my code. I tried everything I had in mind.
I loop it in the main thread like this:
public class MainActivity extends Activity
{
ArrayList <WebPage> wpObjects;
ListView lv;
int threadIsFinishedcounter=0;
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv=(ListView)findViewById(R.id.listView1);
WebPage ynet= new WebPage(R.drawable.ynet, "http://www.ynet.co.il/Integration/StoryRss2.xml","http://www.ynet.co.il/Integration/StoryRss6.xml","http://www.ynet.co.il/Integration/StoryRss3.xml");
WebPage walla=new WebPage(R.drawable.walla, "http://rss.walla.co.il/?w=/1/0/12/#rss.e","http://rss.walla.co.il/?w=/2/0/12/#rss.e","http://rss.walla.co.il/?w=/3/0/12/#rss.e");
WebPage nrg= new WebPage(R.drawable.nrg, "http://rss.nrg.co.il/news/","http://rss.nrg.co.il/finance","http://rss.nrg.co.il/sport");
wpObjects=new ArrayList<WebPage>();
wpObjects.add(ynet);
wpObjects.add(walla);
wpObjects.add(nrg);
for(WebPage item:wpObjects)
{
//new getParseData(wpObjects.indexOf(item)).execute(item.getUrls());
new getParseData(wpObjects.indexOf(item)).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, item.getUrls());
}
if(threadIsFinishedcounter==wpObjects.size())
{
MyCostumedAdapter adapter=new MyCostumedAdapter(MainActivity.this, wpObjects);
lv.setAdapter(adapter);
if(threadIsFinishedcounter==wpObjects.size())
}
}
The AsyncTask class:
class getParseData extends AsyncTask<String,Void, Collecter>
{
int indexofwp;
public getParseData(int indexofwp) {
super();
this.indexofwp = indexofwp;
}
protected Collecter doInBackground(String... params) {
Collecter col = new Collecter() ;
ArrayList<String> allResult = new ArrayList<String>();
ArrayList<String> Titles = new ArrayList<String>();
for (int y = 0; y < params.length; y++) {
Titles.clear();
allResult.clear();
col.yIndex = y;
String urlString = params[y];
try {
URL url = new URL(urlString);
XmlPullParserFactory factory = XmlPullParserFactory
.newInstance();
XmlPullParser parser = factory.newPullParser();
InputStream is = url.openStream();
parser.setInput(is, null);
boolean inItemTag = false;
boolean inTitleTag = false;
String TagName;
int EventType = parser.getEventType();
while (EventType != XmlPullParser.END_DOCUMENT) {
Log.i("im in while loop of parser", "");
if (EventType == XmlPullParser.START_TAG) {
TagName = parser.getName();
if (inItemTag) {
if (TagName.equals("title"))
inTitleTag = true;
} else// !item
{
if (TagName.equals("item"))
inItemTag = true;
}
}
if (EventType == XmlPullParser.TEXT) {
if (inTitleTag) {
Titles.add(parser.getText());// AD THE TITLE
inTitleTag = false;
}
}
if (EventType == XmlPullParser.END_TAG) {
TagName = parser.getName();
if (TagName.equals("item"))
inItemTag = false;
}
EventType = parser.next();
Log.i("im after parser.next", "");
}// end while of parsing loop
} catch (MalformedURLException e) {
e.printStackTrace();
Log.i("EXEPTION******************",
"MalformedURLException*********");
} catch (XmlPullParserException e) {
e.printStackTrace();
Log.i("EXEPTION******************",
"XmlPullParserException*********");
} catch (IOException s) {
s.printStackTrace();
Log.i("IOException***************************", "");
}
synchronized (col) {
if (col.yIndex == 0) {
col.news.addAll(Titles);
col.rssRsult.add(col.news);
}
if (col.yIndex == 1) {
col.economy.addAll(Titles);
col.economy.size()+"");
col.rssRsult.add(col.economy);
}
if (col.yIndex == 2) {
col.sports.addAll(Titles);
col.sports.size()+"");
col.rssRsult.add(col.sports);
}
}
}// end of y loop
return col;
}
#Override
protected void onPreExecute()
{
if(threadIsFinishedcounter==wpObjects.size())
threadIsFinishedcounter=0;
}
#Override
protected void onPostExecute(Collecter coll)
{
if(indexofwp<wpObjects.size())
{
wpObjects.get(indexofwp).NewsTitles.addAll(coll.rssRsult.get(0));
wpObjects.get(indexofwp).EconomicsTitles.addAll(coll.rssRsult.get(1))
wpObjects.get(indexofwp).SportssTitles.addAll(coll.rssRsult.get(2));
threadIsFinishedcounter++;
}
I thought maybe my custom adapter is wrong but didn't find anything wrong:

You should pass your array inyo the constructor and then operate and handle that there. I am sure that you can send your array into your params, but you should make your Asynktask diferent fr string values, as currently you have. So the easy and best way is :
int indexofwp;
List<String> allResult = new ArrayList<String>()
public getParseData(int indexofwp, List<String> allResult)
{
super();
this.indexofwp = indexofwp;
This.allResult=allResult;
}
And thats all.

I am loading the images one by one in Listview by running the task in back ground.I am running a progress bar until it loads fully.The position of progress is not changing when the image starts loading.I want the postion of the progressbar also to be changed when the images loads.How to do it? what am i doing wrong?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

You can set the header to by a textview. It will still be in the same format as a list view but the top item in the list view will be your text view

Your code is looking for R.id.text1
TextView tv = (TextView)findViewById(R.id.text1);
But your xml does not have any such id.
So you will get a null for tv.
