Question

I am having making my edittext field autocomplete for contacts phone numbers. I know how to get contacts from database and display them in text field but i need them to autocomplete just incase the user wants to type a name into textfield. I understand how to get an array to auto complete and the whole theory behind that. But how to pull from phone contacts is difficult. I’ve seen many tutorials and also various question on stack overflow, but still kind of stumped. A code snippit would help please.

public class MyContacts extends Activity {

    AutoCompleteTextView txtPhoneNo;

    public ArrayList<String> c_Name = new ArrayList<String>();
    public ArrayList<String> c_Number = new ArrayList<String>();
    String[] name_Val = null;
    String[] phone_Val = null;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        txtPhoneNo = (AutoCompleteTextView) findViewById(R.id.txtPhoneNo);

    }

    Uri contacts = Uri.parse("content://icc/adn");
    ContentResolver cr = getContentResolver();

    Cursor managedCursor1 = cr.query(contacts, null, null, null, null);
    {
        if (managedCursor1.moveToFirst()) {

            String contactname;
            String cphoneNumber;

            int nameColumn = managedCursor1.getColumnIndex("name");
            int phoneColumn = managedCursor1.getColumnIndex("number");

            Log.d("int Name", Integer.toString(nameColumn));
            Log.d("int Number", Integer.toString(phoneColumn));

            do {
                // Get the field values
                contactname = managedCursor1.getString(nameColumn);
                cphoneNumber = managedCursor1.getString(phoneColumn);
                if ((contactname != " " || contactname != null)
                        && (cphoneNumber != " " || cphoneNumber != null)) {

                    c_Name.add(contactname);
                    c_Number.add(cphoneNumber);
                }

            } while (managedCursor1.moveToNext());
        }
        name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]);
        phone_Val = (String[]) c_Number.toArray(new String[c_Name.size()]);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_dropdown_item_1line, name_Val);
        txtPhoneNo.setAdapter(adapter);
    }
}

My code… no compile errors but still does not work

Answer 1

Better would be to fetch the Contacts and store it in ArrayList. Then you can just bind the ArrayList with the AutoComplete TextView. Then the rest of the part is just easy to filter the ArrayList when you the user types in the AutoComplete TextView.

UPDATE

You can create a POJO Class with getter-setter of contact_name and contact_number. Then create List<POJO> list = new ArrayList<POJO>();. Then just add the contact_name and contact_number to the list using POJO class

POJO pojo_obj = new POJO();
pojo_obj.setcontact_name(contactname);
pojo_obj.setcontact_number(cphoneNumber);
list.add(pojo_obj);

And finally set this list to the Adapter.

And then in the Adapter class you can set it to the TextView using

list.get(position).getcontact_name();
list.get(position).getcontact_number();
