ACTION_HEADSET_PLUG慢广播响应

Question

我希望我的音乐播放器在耳机断开连接时暂停音乐，并在重新连接耳机时恢复音乐。我将此设置为使用广播式接收器，但问题是我在断开耳机连接后，瞬间就能听到扬声器播放的音乐。就像我的接收器不能足够快地接收到广泛的演员？到底怎么回事？

在这里，我在主activity类的onCreate方法中注册了接收器

MusicIntentReceiver receiver = new MusicIntentReceiver();
registerReceiver(receiver, new IntentFilter(Intent.ACTION_HEADSET_PLUG));

下面是我的意图接收器类

public class MusicIntentReceiver extends android.content.BroadcastReceiver {
    @Override
    public void onReceive(Context ctx, Intent intent) {

        if (intent.getAction().equals(android.media.AudioManager.ACTION_HEADSET_PLUG)) {

            if(intent.getIntExtra("state",0)==0){ // 0 for unplugged (if it becomes unplugged)

                //Pause music
            }

            if(intent.getIntExtra("state",0)==1){ // 1 for plugged (if it becomes plugged)

                //Resume music
            }
        }
    }
}

Answer 1

尝试暂停AudioManager.ACTION_AUDIO_BECOMING_NOISY上的音乐-它出现在AudioManager.ACTION_HEADSET_PLUG之前(大约大约1秒)。类似于：

IntentFilter filter = new IntentFilter();
filter.addAction(AudioManager.ACTION_HEADSET_PLUG);
filter.addAction(AudioManager.ACTION_AUDIO_BECOMING_NOISY);
registerReceiver(receiverHeadset, filter);

..。

public class MusicIntentReceiver extends android.content.BroadcastReceiver {
    @Override
    public void onReceive(Context ctx, Intent intent) {
        if (intent.getAction().equals(AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {
            // Pause music
        } else if (intent.getAction().equals(android.media.AudioManager.ACTION_HEADSET_PLUG)) {

            if(intent.getIntExtra("state",0)==1){ // 1 for plugged (if it becomes plugged)

                //Resume music
            }
        }
    }
}
