android - 如何检查android电话簿上的联系人是否启用了whatsapp？

Question

对于我地址簿中的给定号码，我需要查找该号码是否启用了 whatsapp。(思路是选择SMS/WhatsApp发起文本intent)

比方说，我在一个联系人下有两个号码，我需要知道哪个启用了 whatsapp。

Nexus 4 上的“People”应用程序显示两个联系电话，下方还有一个 CONNECTIONS 部分，它仅显示 WhatsApp 可能的联系人。

有没有办法查找(比如 People 应用程序)？

Answer 1

如果您想知道此联系人是否有 WhatsApp:

String[] projection = new String[] { RawContacts._ID };
String selection = ContactsContract.Data.CONTACT_ID + " = ? AND account_type IN (?)";
String[] selectionArgs = new String[] { "THE_CONTACT_DEVICE_ID", "com.whatsapp" };
Cursor cursor = activity.getContentResolver().query(RawContacts.CONTENT_URI, projection, selection, selectionArgs, null);
boolean hasWhatsApp = cursor.moveToNext();
if (hasWhatsApp){
    String rowContactId = cursor.getString(0);
}

并查找此联系人中有多少人拥有 WhatsApp

projection = new String[] { ContactsContract.Data.DATA3 };
selection = ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.Data.RAW_CONTACT_ID + " = ? ";
selectionArgs = new String[] { "vnd.android.cursor.item/vnd.com.whatsapp.profile", rawContactId };
cursor = CallAppApplication.get().getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, selection, selectionArgs, "1 LIMIT 1");
String phoneNumber = null;
if (cursor.moveToNext()) {
    phoneNumber = cursor.getString(0);
}
