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;
}
