因为active类的界面锁屏后会被挂起，所以我们必须使用其它类来实现

BroadcastReceiver接收广播消息，然后再通知界面类去执行一些操作

private final BroadcastReceiver headSetReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (action.equals(Intent.ACTION_HEADSET_PLUG)) {

// phone headset plugged

if (intent.getIntExtra("state", 0) == 1) {

// do something

Log.d("", "耳机检测：插入");

Toast.makeText(context, "耳机检测：插入", Toast.LENGTH_SHORT).show();

mAudioManager.registerMediaButtonEventReceiver(mComponentName);

// phone head unplugged

} else {

// do something

Log.d("", "耳机检测：没有插入");

Toast.makeText(context, "耳机检测：没有插入", Toast.LENGTH_SHORT).show();

mAudioManager.unregisterMediaButtonEventReceiver(mComponentName);

}

if (action.equals(Intent.ACTION_MEDIA_BUTTON)) {

final KeyEvent event = (KeyEvent) intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);

if (event != null && event.getAction() == KeyEvent.KEYCODE_SEARCH) {

// do something

Toast.makeText(Jingwuduijiang.this, "按", Toast.LENGTH_SHORT).show();

}

};
