Hi -- the semi-standard way of getting a contact name from a phone
number is to use Contacts.Phones.CONTENT_FILTER_URL and append the
phone number, as in the following sample code. This works fine on
Android 1.6, but not on 2.0 -- is there a way to perform this function
that works in all versions of the Android API?
private String getContactNameFromNumber(String number) {
// define the columns I want the query to return
String[] projection = new String[] {
Contacts.Phones.DISPLAY_NAME,
Contacts.Phones.NUMBER };
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath
(Contacts.Phones.CONTENT_FILTER_URL, Uri.encode(number));
// query time
Cursor c = getContentResolver().query(contactUri, projection,
null,
null, null);
// if the query returns 1 or more results
// return the first result
if (c.moveToFirst()) {
String name = c.getString(c
.getColumnIndex(Contacts.Phones.DISPLAY_NAME));
return name;
}
// return the original number if no match was found
return number;
}
