Question

I am currently using the ContentProvider for contacts to retrieve the contacts from the device and allowing the user to filter the results by typing into an EditText.

To do so I have set up a filter query on a SimpleAdapter as follows:

    contactsAdapter.setFilterQueryProvider(new FilterQueryProvider() {
        String[] PROJECTION = new String[] {
                ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.Contacts.HAS_PHONE_NUMBER,
        };
        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED COLLATE NOCASE ASC";

          public Cursor runQuery(CharSequence constraint) {
            String SELECTION = "LOWER(" + ContactsContract.Contacts.DISPLAY_NAME + ")" 
            + " LIKE '" + constraint + "%' " + "and " + ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'";
            Cursor cur = managedQuery(ContactsContract.Contacts.CONTENT_URI, 
                    PROJECTION, SELECTION, null, sortOrder);
            return cur; 
          }
        });
    setListAdapter(contactsAdapter); 

This works in most cases however when I have a contact with an accent (Example: Tést Cóntact) then I want the contact to show up even if the user types in Test Contact, currently it doesn’t.

Also the case is not ignored in this case either whereas for standard characters it is, for example if I have a contact called Omar and search for omar it matches but if I have a contact called Ómar and search for ómar it doesn’t match.

Does anyone know what I should be doing to implement the behavior I want to achieve?

Answer 1

I would see 2 options here :

• Create a table that contains accent-less version of the contacts names and a reference to the actual contact Id
• Replace accented caracters by ? in your search (which may result in not really user expected behaviour, but is so much simpler)
