检查耳机是否插好

问题描述

我似乎无法找到一个办法知道在Android上，如果插入耳机，我发现不同的解决方案，但他们似乎总是返回false。这似乎正常工作的唯一事情是一个的BroadcastReceiver ，但是这不是我所需要的：

I can't seem to find a way to know on android if the headphones are plugged in. I found various solutions but they always seem to return false.The only thing that seems to work properly is a BroadcastReceiver, but that's not what I need:

我只需要像这样

if(headphones plugged in) {
}

有没有这样的功能？是否需要一些特殊的权限？

Is there such a function? Does it require some special permissions?

推荐答案

您可以使用 AudioManager.isWiredHeadsetOn（）因为如果耳机插在检查

You can use AudioManager.isWiredHeadsetOn() for checking if the headset are plugged in.

而你需要＆LT;使用-权限的Andr​​oid：名称=android.permission.MODIFY_AUDIO_SETTINGS/＆GT;

可在安卓2.0 +
