Answer 1

Load all the contacts in array list or string array and then use AutoCompleteTextView for adding search functionallity

Gett all contacts like this as expalined here

public ArrayList<PhoneContactInfo> getAllPhoneContacts() {

    Log.d("START","Getting all Contacts");
    ArrayList<PhoneContactInfo> arrContacts = new ArrayList<PhoneContactInfo>();
    PhoneContactInfo phoneContactInfo=null;     
    Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
    Cursor cursor = context.getContentResolver().query(uri, new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER,ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,ContactsContract.CommonDataKinds.Phone._ID}, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    cursor.moveToFirst();
    while (cursor.isAfterLast() == false)
    {
        String contactNumber= cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));  
        String contactName =  cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        int phoneContactID = cursor.getInt(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID));


        phoneContactInfo = new PhoneContactInfo();
        phoneContactInfo.setPhoneContactID(phoneContactID);             
        phoneContactInfo.setContactName(contactName);                   
        phoneContactInfo.setContactNumber(contactNumber); 
        if (phoneContactInfo != null)
        {
            arrContacts.add(phoneContactInfo);
        }
        phoneContactInfo = null; 
        cursor.moveToNext();
    }       
    cursor.close();
    cursor = null;
    Log.d("END","Got all Contacts");
    return arrContacts;
}
