检测拨出电话是否已接听 [英] Detect if an outgoing call has been answered

问题描述

一旦ACTION_NEW_OUTGOING_CALL被广播，我需要捕捉对方回答的以下事件.你能就如何实现这一目标提出建议吗?我知道这是可能的，因为 Android 拨号器应用程序会在他们接电话时将绿色的 Android 图标更改为该人的照片.

Once ACTION_NEW_OUTGOING_CALL has been broadcasted, I need to capture the following event of the other party answer. Could you advice on how to achieve that please? I know it is possible as the Android dialer app changes the green Android icon to the person's photo exactly when they pick up.

更新:我查看了 Android 上处理拨出电话的应用程序的来源.我注意到 ContactsUtils 中的以下方法:

UPDATED: I've had a look at the source of the app on Android handling the outgoing calls. I noticed the following method in ContactsUtils:

/**
 * Kick off an intent to initiate a call.
 */

 public static void initiateCall(Context context, CharSequence
 phoneNumber) {
     Intent intent = new Intent(Intent.ACTION_CALL_PRIVILEGED,
             Uri.fromParts("tel", phoneNumber.toString(), null));
     context.startActivity(intent); }

我想我的答案是在侦听 Intent.ACTION_CALL_PRIVILEGED 的活动中.所以改写我的问题:有谁知道哪个活动处理 Intent.ACTION_CALL_PRIVILEGED?

I guess my answer is in the activity listening for Intent.ACTION_CALL_PRIVILEGED. So to rephrase my question: Does anyone know which activity handles Intent.ACTION_CALL_PRIVILEGED?

推荐答案

我不认为有这样的 API，也没有用于发送 DTMF 的 API，原因与您无法分辨呼叫何时接通的原因相同.

I don't think there's such API and also there's no API for sending DTMFs due to the same reason that you can't tell when the call is being connected.
