バックアップの代替手段として、現在のすべての電話連絡先（名前+電話番号）を含む電子メールをアプリケーションが送信できるアプリケーションを開発しています。電話の連絡先情報をすべて抽出してTextViewに表示する方法を試していますが、できません。誰かに相談してください。ありがとう...

ContactsContract.CommonDataKinds.Phone.CONTENT_URI代わりに使用ContactsContract.Contacts.CONTENT_URIして、電話番号を取得し、これらの回線を変更できるようにします

String name = cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
String number = cursor.getString(cursor.getColumnIndexOrThrow(People.NUMBER));
String email = cursor.getString(cursor.getColumnIndexOrThrow(People.PRIMARY_EMAIL_ID));

に

String name = cursor.getString(cursor.getColumnIndexOrThrow(Phone.DISPLAY_NAME));
String number = cursor.getString(cursor.getColumnIndexOrThrow(Phone.NUMBER));

email_idを取得するには、別のクエリが必要になります。最初のカーソルから、次のような連絡先IDを取得できます。

long contactId = cursor.getLong(cursor.getColumnIndexOrThrow(Phone.CONTACT_ID));

contactId次に、フィルターでを使用して電子メールURIを照会します

long emailId;
Cursor cur = getContentResolver()
                    .query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                     new String[]{"_id"},
                     "contact_id = " + contactId,
                     null,null);
if(cur != null && cur.moveToFirst()){
    emailId = cur.getLong(0);
}
