如何让我的Andr​​oid应用程序检测掉话？ [英] How can my android app detect a dropped call?

问题描述

我写的是指通话过程中运行的应用程序。在用户进行呼叫，并开始我的应用程序，我想我的应用程序才能够知道呼叫来自接触不良下降。这可能吗？谢谢

I am writing an app that is meant to be run during a call. After the user makes a call, and starts my app, I want my app to be able to know if the call is dropped from bad connection. Is this possible? Thanks

推荐答案

Android的 TelephonyManager 类提供了 getCallState（）方法，它会告诉你当前呼叫的状态。你会寻找一个过渡，从 CALL_STATE_OFFHOOK 到 CALL_STATE_IDLE 。

The Android TelephonyManager class provides the getCallState() method, which will tell you the status of the current call. You'll be looking for a transition from CALL_STATE_OFFHOOK to CALL_STATE_IDLE.

不幸的是，我看不出有什么方法来注册一个回调，所以你可能不得不求助于投票。

Unfortunately, I don't see any methods in there to register a callback, so you may have to resort to polling.
