在android中从电话簿检索whatsapp联系人
当我在手机中查看我的联系人时，我也看到了那些拥有whatsapp帐户的人的whatsapp号码。我要做的是过滤我的联系人列表并显示与whatsapp同步的号码。我正在成功检索所有联系人id，与之关联的号码和帐户，但不显示whatsapp帐户。只显示关联的google帐户。是否有任何方法从本地电话簿本身获取whatsapp联系人？我使用了以下代码：在android中从电话簿检索whatsapp联系人,android,android-contacts,whatsapp,Android,Android Contacts,Whatsapp,当我在手机中查看我的联系人时，我也看到了那些拥有whatsapp帐户的人的whatsapp号码。我要做的是过滤我的联系人列表并显示与whatsapp同步的号码。我正在成功检索所有联系人id，与之关联的号码和帐户，但不显示whatsapp帐户。只显示关联的google帐户。是否有任何方法从本地电话簿本身获取whatsapp联系人？我使用了以下代码： ContentResolver cr1 = getContentResolver(); Cursor cur = cr1.query(Contacts
