i have developed an application where i need to show an alert dialog box with list of item,though i have filtered the duplicate data but it is still repeating the items...i really don't have any idea why it is happening...can anybody please help!!

CODE FOR CREATING DIALOG BOX
C#
final CharSequence[] strDates = objEventDataLoader.arrDatesString.toArray(new CharSequence[objEventDataLoader.arrDatesString.size()]);
		
		AlertDialog.Builder objBuilder = new AlertDialog.Builder(this.getActivity());
		objBuilder.setTitle("Pick Date");
		objBuilder.setItems(strDates,
				new DialogInterface.OnClickListener() {

					public void onClick(DialogInterface dialog,
							int Dates) {
						// TODO Auto-generated method stub
						Toast.makeText(getActivity(),
								strDates[Dates],
								Toast.LENGTH_SHORT).show();

					}
				});
		//objBuilder.setView(v);
		AlertDialog objAlert = objBuilder.create();
		objAlert.show();

CODE FOR GETTING ARRAYLIST
C#
public class EventDataLoader {
	
	private static String strJSON;
	private JSONArray arrJSONEventsData;
	public ArrayList<hashmap><string,>> arrEventList = new ArrayList<hashmap><string,>>();	
	public ArrayList<string> arrDatesString = new ArrayList<string>();
	


	public EventDataLoader() {
		readTextFromSource();
	}

	private void onDataLoaded() {
		 
		try {
			
			arrJSONEventsData = new JSONArray(strJSON);
			
			int strCount = arrJSONEventsData.length();
			for (int i = 0; i < strCount; i++) {
				HashMap<string,> objEventsData = new HashMap<string,>();
				JSONObject e = arrJSONEventsData.getJSONObject(i);
				//objLinksData.put("linkURL", String.valueOf(i));
				//objLinksData.put("linkName", e.getString("linkName"));
				objEventsData.put("eventID", e.getString("eventID"));
				objEventsData.put("eventPreviousID", e.getString("eventPreviousID"));
				objEventsData.put("eventDate", e.getString("eventDate"));
				//objLinksData.put("linkID", e.getString("linkID"));
				arrEventList.add(objEventsData);
				arrDatesString.add(e.getString("eventDate"));
				
		
			}
			
			checkDataDuplicacy();
			
		} 
		catch (JSONException e) {
			Log.e("log_tag", "Error parsing data " + e.toString());
		}
	}

	private void readTextFromSource() {
		try {
			// Create a URL for the desired page
			URL url = new URL(" ") ;

			// Read all the text returned by the server
			BufferedReader in = new BufferedReader(new InputStreamReader(
					url.openStream()));
			String str;
			StringBuilder sb = new StringBuilder(100);
			while ((str = in.readLine()) != null) {
				sb.append(str);
				// str is one line of text; readLine() strips the newline
				// character(s)
			}
			in.close();
			strJSON = sb.toString();
			onDataLoaded();
		} catch (MalformedURLException e) {

		} catch (IOException e) {

		}
	}
	private void checkDataDuplicacy()
	{
		for (int i = 0; i < arrEventList.size(); i++) 
		{
			removeIfDuplicateAvailable(i);
		}
		
	}
	
	private void removeIfDuplicateAvailable(int nCount)
	{
		HashMap<string,> objEventsData = arrEventList.get(nCount);
		String strPrvsId = objEventsData.get("eventPreviousID");
		if(strPrvsId.equalsIgnoreCase("-1"))
		{
			
		}
		else
		{
			removeEventObjectWithPrvsId(strPrvsId);
		}
	}
	
	private void removeEventObjectWithPrvsId(String strPrvsId)
	{
		for (int i = 0; i < arrEventList.size(); i++) 
		{
			HashMap<string,> objEventsData = arrEventList.get(i);
			if(strPrvsId.equalsIgnoreCase(objEventsData.get("eventID")))
			{
				Log.i("development","Finally Removing");
				arrEventList.remove(i);
				arrDatesString.remove(i);
				Log.i("development",arrDatesString.get(i));
				return;
			}
		}
	}

It's impossible to know without seeing the code you're using to create the dialog...
