环境：

主机:WIN10

开发环境:Android Studio 2.2 Preview 3

说明：

增加权限：<uses-permission Android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

源码：

HeadsetPlusReceiver.java:

package com.bazhangkeji.classroom.common; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.media.AudioManager; import android.widget.Toast; import com.bazhangkeji.classroom.IM.Voip; public class HeadsetPlusReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE); if (audioManager.isWiredHeadsetOn()) { Voip.getInstance().disableLoudspeakerStatus(); Toast.makeText(context, "耳机插入", Toast.LENGTH_SHORT).show(); } else { Voip.getInstance().enableLoudspeakerStatus(); Toast.makeText(context, "耳机拔出", Toast.LENGTH_SHORT).show(); } } }

在活动种注册服务：

private void listenHeadsetPlus() { AudioManager audioManager = (AudioManager) getActivity().getSystemService(Context.AUDIO_SERVICE); if (audioManager.isWiredHeadsetOn()) { Voip.getInstance().disableLoudspeakerStatus(); } else { Voip.getInstance().enableLoudspeakerStatus(); } IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction("android.intent.action.HEADSET_PLUG"); headsetPlusReceiver = new HeadsetPlusReceiver(); getContext().registerReceiver(headsetPlusReceiver, intentFilter); }

退出活动时注销服务：

if (headsetPlusReceiver != null) { getContext().unregisterReceiver(headsetPlusReceiver); headsetPlusReceiver = null; }
