Android的新CallLog.Calls.NUMBER_PRESENTATION字段有什么用途？ [英] What's the use of Android's new CallLog.Calls.NUMBER_PRESENTATION field?

问题描述

我注意到在API级别19（Kitkat）中添加了一个名为CallLog.Calls.NUMBER_PRESENTATION的新字段。

I noticed a new field was added in API level 19 (Kitkat) called CallLog.Calls.NUMBER_PRESENTATION.

文档说

网络设置的数字显示规则。

The number presenting rules set by the network.

允许的值：
PRESENTATION_ALLOWED
PRESENTATION_RESTRICTED
PRESENTATION_UNKNOWN
PRESENTATION_PAYPHONE

Allowed values: PRESENTATION_ALLOWED PRESENTATION_RESTRICTED PRESENTATION_UNKNOWN PRESENTATION_PAYPHONE

有人知道这是什么意思吗？/

Does anyone know what is this used for / according to what is this set?

推荐答案

我已将其签出。

似乎它可以让您知道呼叫者所拥有的内容设置为在手机上显示。

Seems it allows you to know, for example, what the caller has set to display on your phone.

这意味着，如果呼叫者选择不显示其电话，则可能为 PRESENTATION_RESTRICTED 。

This means, that if the caller chose not to have its phone be shown, it could be PRESENTATION_RESTRICTED .

对于正常的电话号码，我可以看到它是 PRESEN TATION_ALLOWED 。不知道何时会出现其他值。

For normal phone numbers, I can see it's PRESENTATION_ALLOWED . No idea when the other values appear though.

我之所以这样做，是因为某些原因，在私有号码（又称为未知号码）上，呼叫者的电话号码是隐藏的，在Galaxy S7上，我实际上得到的电话号码是 -2，这是没有意义的（应该为空或空）。

The reason I reached this, BTW, is because for some reason, on private numbers (AKA "unknown numbers"), where the phone number of the caller is hidden, on Galaxy S7 I actually get a phone number "-2", which doesn't make sense (should be null or empty).
