AutoComplete TextView with Contacts

Question

i need to display an auto complete text box which will basically load the contacts e-mail ids. I have tried it using a custom adapter but nothing gets populated in the textb

Answer 1

Try the following:

ArrayList emailAddressCollection = new ArrayList();

ContentResolver cr = getContentResolver();

Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, null, null, null);

while (emailCur.moveToNext())
{
    String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
            emailAddressCollection.add(email);
}
emailCur.close();

String[] emailAddresses = new String[emailAddressCollection.size()];
emailAddressCollection.toArray(emailAddresses);

ArrayAdapter adapter = new ArrayAdapter(this,
             android.R.layout.simple_dropdown_item_1line, emailAddresses);
AutoCompleteTextView textView = (AutoCompleteTextView)findViewById(R.id.YOUR_TEXT_VIEW);
     textView.setAdapter(adapter);
 }

Note: Don't forget to add the READ_CONTACTS permission to your Manifest.xml:
