I'm trying to find a contact by display name. The goal is to open this contact and add more data to it (specifically more phone numbers), but I'm struggling to even find the contact I want to update.
This is the code I'm using:
public static String findContact(Context context) {
ContentResolver contentResolver = context.getContentResolver();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI;
String[] projection = new String[] { PhoneLookup._ID };
String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " = ?";
String[] selectionArguments = { "John Johnson" };
Cursor cursor = contentResolver.query(uri, projection, selection, selectionArguments, null);
if (cursor != null) {
while (cursor.moveToNext()) {
return cursor.getString(0);
}
}
return "John Johnson not found";
}
I do have a contact called "John Johnson", but the method always returns "not found". I also tried searching for a contact with just one name, so that makes no difference.
I suspect that it's something wrong with the uri, selection or selection arguments, because I couldn't find any example online of searching for contacts with a given display name, and it seems display name is a special kind of information, different from for example a phone number.
Any ideas how I can achieve to find John Johnson?
UPDATE: I found out how to find a contact by display name:
ContentResolver contentResolver = context.getContentResolver();
Uri uri = Data.CONTENT_URI;
String[] projection = new String[] { PhoneLookup._ID };
String selection = StructuredName.DISPLAY_NAME + " = ?";
String[] selectionArguments = { "John Johnson" };
Cursor cursor = contentResolver.query(uri, projection, selection, selectionArguments, null);
if (cursor != null) {
while (cursor.moveToNext()) {
return cursor.getString(0);
}
}
return "John Johnson not found";
This code returns the contact id of the first contact with display name "John Johnson". In my original code I had the wrong uri and the wrong selection in my query.
