我试图通过电话获得whatsapp联系,我得到whatsapp联系的总数,但是从RawContacts如何获得whatsapp我不知道的号码和名称.我试图找到解决方案,但无法得到确切的解决方案.请帮我.

我把我的代码放在下面.

ContentResolver cr = context.getContentResolver();

Cursor c = cr.query(
                        ContactsContract.RawContacts.CONTENT_URI,
                        new String[] { ContactsContract.RawContacts.CONTACT_ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY },
                        ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?",
                        new String[] { "com.whatsapp" },
                        null);

                ArrayList<String> myWhatsappContacts = new ArrayList<>();

                String projection[] = { ContactsContract.CommonDataKinds.Phone.NUMBER };

                if(c != null) {
                    if (c.getCount() > 0) {
                        while (c.moveToNext()) {

                            String whatsappContactId = c.getString(c.getColumnIndex(ContactsContract.RawContacts.Data._ID));

                            Cursor dataCursor = cr.query(
                                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                                    projection,
                                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                                    new String[]{whatsappContactId}, null);
                            // You can also read RawContacts.CONTACT_ID to read the
                            // …

我正在尝试将数据记录添加到已存在的联系人中,我使用电话查找找到该联系人,我将联系_id字段,并添加一个新数据,并将raw_contact_id设置为_id字段.在一些联系人它只是不起作用,它将数据与不同的联系人匹配.(我认为它与存储在SIM卡上的联系人有关)

请指教,也许你有不同的方式来添加数据

代码示例:

LinkedList<Long> lcv = new LinkedList<Long>();
    ContentResolver cr = getContentResolver();
    Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
    Cursor c = cr.query(uri, null, null, null, null);
    try {
        while (c.moveToNext()) {
            Uri lookupUri = Uri.withAppendedPath(Contacts.CONTENT_LOOKUP_URI,
                    c.getString(c.getColumnIndex(PhoneLookup.LOOKUP_KEY)));
            Cursor c2 = getContentResolver().query(lookupUri, new String[] { Contacts._ID, Contacts.DISPLAY_NAME },
                    null, null, null);
            try {
                if (c2.moveToNext()) {
                    Log.i(TAG, "found: " + c2.getLong(c2.getColumnIndex(Contacts._ID)) + ", " + c2.getString(c2.getColumnIndex(Contacts.DISPLAY_NAME)));
                    lcv.add(c2.getLong(c2.getColumnIndex(Contacts._ID)));
                } else {
                    Log.e(TAG, "failed to lookup");
                }
            } finally {
                c2.close();
            }
        }
    } finally …
