View list in android

Question

View list in android

I have a list that displays 50 items. I decided to split the pages so that there were 10 elements on each part of the view, and then the next button was pressed to go to the next 10 elements. How can I set 10 data? I'm following this article http://rakhi577.wordpress.com/2013/05/20/listview-pagination-ex-2/ Here is my code. Can you help me with my code or a link to a guide on how to implement this correctly?

public class MainActivity extends ListActivity {


Context context;
Button btnSearch ;
EditText txtSearch;

private ProgressDialog pDialog;

// URL to get contacts JSON

    public int TOTAL_LIST_ITEMS = 50;
    public int NUM_ITEMS_PAGE   = 10;
    private int noOfBtns;
    private Button[] btns;


// JSON Node names
private static final String TAG_CONTACTS = "contacts";
private static final String TAG_ID = "id";
private static final String TAG_NAME = "name";
private static final String TAG_EMAIL = "email";

private static final String TAG_GENDER = "gender";
private static final String TAG_PHONE = "phone";
private static final String TAG_PHONE_MOBILE = "mobile";
private static final String TAG_PHONE_HOME = "home";
private static final String TAG_PHONE_OFFICE = "office";

// contacts JSONArray
JSONArray contacts = null;

// Hashmap for ListView
ArrayList<HashMap<String, String>> contactList;

@Override

    super.onCreate(savedInstanceState);
