android - 如何收听SpeakerPhone更改
[英]android -how to listen to SpeakerPhone change
问题描述
I'd like to be able to listen to on/off events of the android native speakerphone button.
我希望能够收听 android 原生扬声器按钮的开/关事件。
Realizing i could spawn a child thread and keep checking for AudioManager.isSpeakerphoneOn();意识到我可以产生一个子线程并继续检查 AudioManager.isSpeakerphoneOn(); thats just going to kill battery life etc etc. Is there a listener for this ?那只会缩短电池寿命等等。有没有听众？

Starting from API 29 , you can register a BroadcastReceiver using the Intent filter AudioManager.ACTION_SPEAKERPHONE_STATE_CHANGED .从API 29开始，您可以使用 Intent 过滤器AudioManager.ACTION_SPEAKERPHONE_STATE_CHANGED注册BroadcastReceiver 。
Documentation is available in the Android official page here .文档可在此处的 Android 官方页面中找到。
Unfortunately I didn't found any other way except polling, for APIs < 29.不幸的是，对于 API < 29，除了轮询之外，我没有找到任何其他方法。
