PhoneStateListener()尚未完成 [英] PhoneStateListener() isn´t finished

问题描述

我实现了PhoneStateListener，该方法如何在被呼叫时停止音频并在完成后重新启动. 当我通过finish()退出我的应用程序时，PhoneStateListener似乎仍然处于活动状态.通话结束后，音乐开始播放. 即使我在onDestroy()中设置了listener = null，它仍然可以正常工作...

I implemented a PhoneStateListener how stops audio if you are called and starts it again after you finished. When i exit my app by finish() the PhoneStateListener seems to be still active. After finishing a call the music starts to play. Even if I set the listener=null in onDestroy() it keeps working...

推荐答案

在listen()的文档rel ="nofollow"> TelephonyManager :

Quoting the documentation for listen() on TelephonyManager:

要注销注册侦听器，请传递该侦听器对象，并将events参数设置为LISTEN_NONE(0).

To unregister a listener, pass the listener object and set the events argument to LISTEN_NONE (0).

您必须在活动超出范围(例如在onPause()或onDestroy()中)之前执行此操作.

You must do this before your activity goes out of scope, such as in onPause() or onDestroy().
