Source code:

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();
        }
    }
}

Register services in the event:

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);
    }

To log off the service when exiting the event:

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