推荐答案

随着 READ_CONTACTS 允许在你的清单，你可以得到同步给出的帐户类型的联系人。对于WhatsApp的是com.whatsapp。所以：

With the READ_CONTACTS permission in your manifest, you can get synced contacts given the account type. For WhatsApp it's "com.whatsapp". So:

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

ArrayList<String> myWhatsappContacts = new ArrayList<String>();
int contactNameColumn = c.getColumnIndex(RawContacts.DISPLAY_NAME_PRIMARY);
while (c.moveToNext())
{
    // You can also read RawContacts.CONTACT_ID to read the
    // ContactsContract.Contacts table or any of the other related ones.
    myWhatsappContacts.add(c.getString(contactNameColumn));
}
