Question

How can I get a phone's contact list in a FireMonkey mobile application?

Answer 1

here you go .. It's not finished as it reads all numbers for one person and if there are two numbers you will have two times this person listed inside list .. but from here I think you can work and adjust it to your needs :))

function GetContact: TStringList;
var
cursorContacts, cursorContactsPhone: JCursor;
hasPhoneNumber: Integer;
id: Int64;
displayName, phoneNumber, contactID: string;
begin
Result := TStringList.Create;
cursorContacts := SharedActivity.getContentResolver.query(TJContactsContract_Contacts.JavaClass.CONTENT_URI, nil, nil, nil, nil);
if (cursorContacts.getCount > 0) then
begin
while (cursorContacts.moveToNext) do
begin
id := cursorContacts.getLong(cursorContacts.getColumnIndex(StringToJString('_ID')));
displayName := JStringToString(cursorContacts.getString(cursorContacts.getColumnIndex(StringToJString('DISPLAY_NAME'))));
hasPhoneNumber := cursorContacts.getInt(cursorContacts.getColumnIndex(StringToJString('HAS_PHONE_NUMBER')));
if (hasPhoneNumber > 0) then
begin
cursorContactsPhone := SharedActivity.getContentResolver.query(TJCommonDataKinds_Phone.JavaClass.CONTENT_URI, nil,StringToJString('CONTACT_ID = ' + IntToStr(id)),nil, nil);
while (cursorContactsPhone.moveToNext) do
begin
phoneNumber := JStringToString(cursorContactsPhone.getString(cursorContactsPhone.getColumnIndex(StringToJString('DATA1'))));
contactID := JStringToString(cursorContactsPhone.getString(cursorContactsPhone.getColumnIndex(StringToJString('CONTACT_ID'))));
Result.Add(displayName + ': ' + phoneNumber);
end;
cursorContactsPhone.close;
end;
end;
end;
cursorContacts.close;
end;
