Dynamically updating list view from XML file at server in Android

I've an XML file present at server, I want to update my list view by using data present at XML file in server and whenever the data is updated in XML, it will reflect automatically in list. I've a code that's working fine separately but when i put the same code in my project it won't work.
Here is my code:
ContactDetail.xml The file to parse

If I create a new project and add these files there then that works fine but when i put it in my project it is not able to work,....
it fetches data only once and then never fetches data from server....

To Implement these ListActivity to display videos in url

I need to implement these ListActivity.java
ListActivity.java:

public class ListActivity extends Activity {
private ListView lv;
private String[] groupArray = {"Category1", "Category2", "Category3"};
private String[][] childArray = {{"Test Greater glory Part-3","Greater glory Part-1"},

public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.list1);
lv = (ListView) findViewById(R.id.listview);
String[] data = getIntent().getStringArrayExtra("strArray");
AdapterView.OnItemClickListener clickListener = null;
// If no data received means this is the first activity
if (data == null) {
data = groupArray;
clickListener = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new Intent(ListActivity.this, ListActivity.class);
intent.putExtra("strArray", childArray[position]);
startActivity(intent);
}
};
}
ArrayAdapter adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, data);
lv.setAdapter(adapter);
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(clickListener);
}
}
list1.java:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

If I click the Category1 in that ListView.Another ListView shown.
My problem is,If I click the TestGreater Glory Part-3, the video have to display from URL.I doesn't know how to implement that ListActivity Class to the below codings.

<string name="str_video">VIDEO</string>
<string name="api_host">URL Here</string>

actionabar.setDisplayHomeAsUpEnabled(true);

if (!wasRestored) {
try {
if (videoId != null) {
// 2GPfZYwYZoQ
player.cueVideo(videoId);
} else {
Toast.makeText(getApplicationContext(),
"Not a Valid Youtube Video", Toast.LENGTH_SHORT)
.show();
}
} catch (Exception e) {

}

I need to implement that ListActivity.java Class to get the videos shown in the url.

Here's an app that lists categories (that you provide). After clicking some category, it's videos will be loaded from the JSON file and displayed as another ListView.
When you click on a video, it's url and title is sent to the YoutubeActivity. YoutubeActivity then starts a player with that video.
I believe you wanted something more complex but you can add the other functionality (such as getting additional fields from the json) quite easily. If you would want to import categories also, then you'd need another json structure such as array of categories->array of videos.
ListActivity:

And you need to implement the YoutubeAPI into your project.
Download YouTube API
build.gradle compile files('libs/YouTubeAndroidPlayerApi.jar')

I just tried to re-create this project and it worked perfectly. Here's my layout and manifest files, maybe they're causing you trouble.

Now you can get all the details in that spinner...

You can't Performing Network Operations ON GUI thread so you have to create a thread to fitch and parse data from URL.
public void onClick(View v) {
new Thread(new Runnable() {
#Override
public void run() {
item = SAXXMLParser.parse(URL);
spinhandler.sendEmptyMessage(0);
}
}).start();
}
Create Handler
private Handler spinhandler = new Handler() {
#Override
public void handleMessage(Message msg) {
if(msg.what == 0) {
ArrayAdapter<Item> adapter = new ArrayAdapter<Item>(MainActivity.this, R.layout.list_item, item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(MainActivity.this);
}
}
};
When try to put data in Item Object the Item object equal null so you have to intialize the object before start access it
if (qName.equalsIgnoreCase("id")) {
tempEmp = new Item();
tempEmp.setId(Integer.parseInt(tempVal));
}

And remove this code.

Just make Custom List View using array adapter.
refer this example..
http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/

The web is full of tutorial and example of ListView using Custom Adapter. You will have to spend some time trying to learn them. No shortcuts. You can one of them here or you can select one of the books from Amazon.
