Answer 1

 String lastnumber = "0";
    ContentResolver cr = getContentResolver();
    Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, Constants.PROJECTION, null, null, null);
    if (cursor != null) {
        try {
            final int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
            final int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            String name, number;
            while (cursor.moveToNext()) {
                name = cursor.getString(nameIndex);
                number = cursor.getString(numberIndex).trim();
                number = number.replaceAll("\\s", "");
                if (number.equals(lastnumber)) {

                } else {
                    lastnumber = number;
                    Contact contact = new Contact();
                    contact.name = name;
                    contact.phone = number;
                    mContactList.add(contact);
                    if (adapter != null)
                        adapter.notifyDataSetChanged();
                    System.out.println("ContactFragment.readContact ==>" + name);
                }
            }
        } finally {
            cursor.close();
        }
    }
