在一个电话在Android上月底启动一个活动 [英] Launch an activity at end of a phone call on Android

问题描述

我想推出一个活动，在电话的结束。 找不到任何提及这一点。我该怎么办呢？

I would like to launch an activity at the end of a phone call. Could not find any reference to that. How can I do it?

推荐答案

我还没有尝试过，但我会假设你可以有一些服务运行（在后台总是），它利用的 PhoneStateListener 。然后，您可以收听 LISTEN_CALL_STATE 它说，它侦听更改设备的呼叫状态。我会假设，当一个呼叫启动，停止，等等，那么你可以启动从服务的活动，当你接到一个电话结束的消息，这将触发。

I haven't tried this, but I would assume you could have some service running(always on in background), that utilizes the PhoneStateListener. You could then listen for LISTEN_CALL_STATE which says it "Listen for changes to the device call state". I would assume this would fire when a call starts, stops, etc. You could then launch your activity from the service when you receive a message that a call ended.

请注意，你可能就必须跟踪状态，并没有当你在 CALL_STATE_OFFHOOK ，进入 CALL_STATE_IDLE 呼叫结束。

Note you would probably have to track the states, and no when you are in CALL_STATE_OFFHOOK and go to CALL_STATE_IDLE that the call ended.
