我正在尝试更新联系人显示名称和电子邮件。经过大量努力，通过以下代码 fragment 实现了这一点。但是当我在联系人应用程序中看到它时，我提供的任何更新名称都在它后面附加了 2，这是一个问题。

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();

ops.add(ContentProviderOperation
        .newUpdate(
                ContactsContract.Data.CONTENT_URI)

        .withSelection(
                ContactsContract.CommonDataKinds.Email.CONTACT_ID
                        + " = ?",
                new String[] { String.valueOf(model
                        .getContactid()) })
        .withValue(ContactsContract.Data.MIMETYPE,
                Email.CONTENT_ITEM_TYPE)
        .withValue(
                ContactsContract.CommonDataKinds.Email.DATA,
                "priyankay27@gmail.com")
        .withValue(
                ContactsContract.CommonDataKinds.Email.DISPLAY_NAME,
                "priyanka")
        .withValue(
                ContactsContract.CommonDataKinds.Email.TYPE,
                ContactsContract.CommonDataKinds.Email.TYPE_WORK)
        .build());

getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

Context ctx = getApplicationContext();
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(ctx,"Update successful", duration);
toast.show();

Logger.debug("Update successful");

这会将显示名称更新为“priyanka 2”而不是“priyanka”，如您所见，显示名称后附加了 2。

最佳答案

终于可以运行了，这里是我的代码，感谢大家的回复和支持

    final ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();

    Cursor cursorEmail = getContentResolver()
            .query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                    null,
                    ContactsContract.CommonDataKinds.Email.CONTACT_ID
                            + " = "
                            + model.getContactid(),
                    null, null);

    if (cursorEmail.moveToFirst()) {

      //Update Email 

        ops.add(ContentProviderOperation
                .newUpdate(Data.CONTENT_URI)
                .withSelection(
