安卓：检查是否插入耳机 [英] Android: Checking if headphones are plugged in

问题描述

我如何检查是否插入耳机，在目前堵塞。我不想一个BroadcastReceiver它告诉我，当他们已经​​连接到设备上。我需要的是这样的：

 如果（/ *耳机连接* /）
 ...
 

解决方案

看起来你会感兴趣的<一个href="http://developer.android.com/intl/de/reference/android/media/AudioManager.html#isWiredHeadsetOn%28%29"><$c$c>isWiredHeadsetOn()法和<一href="http://developer.android.com/intl/de/reference/android/media/AudioManager.html#isBluetoothA2dpOn%28%29"><$c$c>isBluetoothA2dpOn()方法 <一个href="http://developer.android.com/intl/de/reference/android/media/AudioManager.html"><$c$c>AudioManager类。

不过， isWiredHeadsetOn（）方法仅适用于Android的2.0或更高版本可用。 （该 isBluetoothA2dpOn（）方法由于Android 1.5可用。）

How can I check if headphones are currently plugged in. I don't want a broadcastreceiver which informs me when they have been connected to the device. I need something like:

if(/*headphone is connected*/)
 ...

解决方案

It looks like you'll be interested in the isWiredHeadsetOn() method and isBluetoothA2dpOn() method of the AudioManager class.

However, the isWiredHeadsetOn() method is only available in Android 2.0 or later. (The isBluetoothA2dpOn() method has been available since Android 1.5.)
