如何在Android中获取拨出电话号码？ [英] How to get outgoing call number in android?

问题描述

我正在尝试使用 intent.getStringExtra（Intent.EXTRA_PHONE_NUMBER）获取拨出电话号码，但每次尝试时都会返回null。我确实在Androidmanifest中放置了所需的权限和操作。有人可以告诉我我做错了什么或如何以另一种方式回复数字？

I am trying to get outgoing call number with intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER), but every time I try it returns null. I did put needed permissions and action in Androidmanifest. Can someone tell me what I am doing wrong or how to retrive number another way?

推荐答案

好的，我发现了什么是错的。

Ok, I found out what was wrong.

首先，当电话状态变为空闲时，intent.getStringExtra（Intent.EXTRA_PHONE_NUMBER）为您提供传出号码，当电话状态变为OFF_HOOK时，将变为空。

First of all intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER) gives you outgoing number while phone state is idle and turns to "null" while phone status changes to OFF_HOOK.

最简单的方法是在另一个onRecive发生之前保存该号码。

The easiest way was to save the number before another onRecive happens.
