如何确定耳机是否已插入 Android 设备?

How can I determine whether a headset is plugged into an Android device or not?

推荐答案

当您说耳机"时，您指的是有线耳机"吗?如果是这样，则意图检测是否正在插入或拔出:ACTION_HEADSET_PLUG.

When you say "headset", do you mean "wired headset"? If so, there's an intent to detect whether or not one is being plugged or unplugged: ACTION_HEADSET_PLUG.

要检查状态，您可以使用 AudioManager.isWiredHeadsetOn()，尽管如果还有蓝牙耳机，则可能会返回 false，而音频会转而路由到该耳机.

To check the status, you can use AudioManager.isWiredHeadsetOn(), although that may return false if there is also a bluetooth headset, and audio is routed to that instead.
