我使用下面的代码获取设备联系人它工作正常,但显示重复的联系人条目.
//FETCH DEVICE CONTACTSpublic voID fetchDeviceContacts(){ Constant.progressDialog = ProgressDialog.show(ContactListActivity.this,"","Please wait..."); Uri contactsUri = ContactsContract.Contacts.CONTENT_URI;

解决方法 您看到重复,因为相同的联系人可能属于不同的组.例如电子邮件帐户1和电子邮件帐户2.您可以在 http://developer.android.com/guide/topics/providers/contacts-provider.html获得有关原始联系人数据的子标题源的更多信息 总结
