做的事情，如果它检测到耳机插入 [英] Doing something if it detects that headphones are plugged in

问题描述

我想使它所以如果耳机在设备中插入事情发生，如出现一个通知图标。 （我已经通知图标的东西做的），但我似乎无法找到一个方法来做到这一点。我想这样的事情

I'm wanting to make it so if headphones are plugged in the device something happens such as a notification icon appears. (I already have the notification icon stuff done) But I can't seem to find a way to make it happen. I'm wanting something like this

if headphones_plugged_in {
do this 
}

我发现这个网上

AudioManager.isWiredHeadsetOn()

我只是不知道我怎么会使用它。我已经在清单中添加正确的权限呢！如果你能引导我或链接我的东西这将是巨大的。谢谢！

I just don't know how I would use that. I already added the right permissions in the manifest too! If you could guide me or link me to something it would be great. Thank You!

推荐答案

添加＆lt;接收＆GT; 在清单监听的在 ACTION_HEADSET_PLUG 播出。
文档显示意图，你可以用它来看看耳机的（状态）等额外堵塞

Add a <receiver> in your manifest that listens for the ACTION_HEADSET_PLUG broadcast. The documentation shows Intent extras that you can use to find out if the headset is plugged in (state), etc.
