Question

I want to implement a search in my Android application.
In this page, first I am displaying a user list and then performing a search on the user list. Both are in the same activity. In the following manner, I am getting intent and some values from the previous page. When I display the user list, all the values are coming. But while performing search, spaceId gets lost and becomes null. I need this value.

Intent intent = this.getIntent();
Bundle receiveBundle = intent.getExtras();
spaceId = receiveBundle.getString("spaceId");

What should I do to get this value?

Edit:

String spaceId;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    Intent intent = this.getIntent();
        Bundle receiveBundle = intent.getExtras();
        spaceId = receiveBundle.getString("spaceId");
        String URLTicketList = String.format(getString(R.string.URLTicketList, spaceId));
        RestClient client = new RestClient(URLTicketList,
                this.getApplicationContext());
        try {
            client.Execute(RequestMethod.GET);
        } catch (Exception e) {
            e.printStackTrace();
        }

        TabSettings ts = new TabSettings();
        ts.setSelTab(0);
        String response  = client.getResponse();
        tickets = parseTicketList(response);
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {

            String query = intent.getStringExtra(SearchManager.QUERY);
            searchResult=getMatchingStrings(tickets,query);
            this.ticket_adapter = new TicketAdapter(this,
                        R.layout.ticket_details_row,searchResult);
            setListAdapter(this.ticket_adapter);
        }
        else  {
            this.ticket_adapter = new TicketAdapter(this,
                        R.layout.ticket_details_row, tickets);
            setListAdapter(this.ticket_adapter);
        }

    }

getMatchingstrings()

ArrayList<Ticket> getMatchingStrings(ArrayList<Ticket> list, String regex1)     {
        ArrayList <Ticket> listClone = new ArrayList<Ticket>(); 
            for (Ticket string : list) {
                    if(string.getAssignedTo().equals(regex1)){
                listClone.add(string);
                }
            }

          return listClone;
        }

You said your activity is recreating. So you are not getting the value of spaceID after recreation. Then do this thing as below.

public String PREFS_NAME = "Shared_Pref";

Bundle receiveBundle = this.getIntent().getExtras();
String spaceId_value = receiveBundle.getString("spaceId");

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);

if(spaceId_value == null) {
     spaceId_value = settings.getString("spaceId", "");
}
else {
     SharedPreferences.Editor editor = settings.edit();
     editor.putString("spaceId", spaceId_value);
}

I hope this will help you out.

edit :

I am editing your code.

Which part i have edited, i have mentioned that part as edited. Carefully see what i have changed and do that thing in your code. Then let me know.

     String spaceId;
     public String PREFS_NAME = "Shared_Pref";  //edited part

     public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        //editing start

         SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
         Bundle receiveBundle = this.getIntent().getExtras();
         if(receiveBundle != null) {
             spaceId = receiveBundle.getString("spaceId");
             if(spaceId == null) {
                 spaceId = settings.getString("spaceId", "");
             }
             else {
                 SharedPreferences.Editor editor = settings.edit();
                 editor.putString("spaceId", spaceId);
             }
         }

        //editing end

        String URLTicketList = String.format(getString(R.string.URLTicketList, spaceId));
        RestClient client = new RestClient(URLTicketList,
            this.getApplicationContext());
        try {
            client.Execute(RequestMethod.GET);
        } catch (Exception e) {
            e.printStackTrace();
        }

        TabSettings ts = new TabSettings();
        ts.setSelTab(0);
        String response  = client.getResponse();
        tickets = parseTicketList(response);
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {

            String query = intent.getStringExtra(SearchManager.QUERY);
            searchResult=getMatchingStrings(tickets,query);
            this.ticket_adapter = new TicketAdapter(this,
                        R.layout.ticket_details_row,searchResult);
            setListAdapter(this.ticket_adapter);
        }
        else  {
            this.ticket_adapter = new TicketAdapter(this,
                        R.layout.ticket_details_row, tickets);
            setListAdapter(this.ticket_adapter);
        }

    }
