Using the Uri provided by ContentResolver and ContentProvider, you can obtain the address book in the system Management contact Uri: ContactsContract.Conacts.CONTENT_URI Phone Uri: ContactsContract.CommonDataKinds.Phone.CONTENT_URI
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null); //遍历结果 if (cursor.moveToNext()){ //联系人ID String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); //联系人名字 String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); .... }
