private Cursor cursor;
final VROPreferenceManager preferenceManager = new VROPreferenceManager();
Context con;
public FriendsListCursorAdapter(Context context, Cursor c, boolean b) {
super(context,c,true);
cursor = c;
con=context;
}
public void addItems(Cursor newItems) {
if (0 == newItems.getCount()) {
return;
}
notifyDataSetChanged();
}
public int getCount() {
// TODO Auto-generated method stub
return cursor.getCount();
}

FriendInfoTable is a class where table and fields are created look like
public class FriendinfoTable {
public static final String TABLE_NAME = "friendinfotable";
public static class Cols {
public static final String ID = "_id";
public static final String FIRST_NAME = "first_name";
public static final String LAST_NAME = "last_name";
public static final String USER_NAME = "user_name";
public static final String EMAIL="email";
public static final String USER_PROFILE_PIC="user_profile_pic";
public static final String USER_TIMELINE_PIC="user_timeline_pic";
public static final String COUNTRY="country";
public static final String STATE="state";
public static final String CITY="city";
public static final String ABOUT="about";
public static final String GENDER="gender";
public static final String DATEOFBIRTH="dob";
public static final String FRIENDSHIP_STATUS="friendship_status";
public static final String QUICKBLOX_ID="quickblox_id";
}
}
