我试图探测机器人的声音，并暂停我的应用程序的音乐（暂时或永久），而他们制造噪音。

I'm trying to detect android sounds and pause my app's music (temporarily or permanently) while they make noise.

这code显得无能为力（停止的暂停音乐和 P 的写入日志），它永远不会被调用：

This code appears to do nothing (stop pauses the music and p writes to the log), it never gets called:

public class PollyPrissyPants extends Activity implements OnAudioFocusChangeListener {
    // Blah blah blah
    public void onAudioFocusChange(int mal) {
        p("--CHANGE!!!--" + mal);
        stop();
    }
    // Yada yada yada
}

我必须将其设置在其他地方呢？是@覆盖相关？

Do I have to set it up somewhere else as well? Is @Override relevant?

我还没有试过PhoneStateListener但如果可能，我不希望有单独对待电话，报警，通知，游戏等。我使用了震动，但现在它吮吸作为解决方案。如果我叫，我来回答，然后迅速得到我的应用程序，并暂停。

I haven't tried PhoneStateListener but if possible I don't want to have to treat phone calls, alarms, notifications, games, etc separately. I'm using vibrate for now but it sucks as a solution. If I get called, I have to answer and then quickly get to my app and pause it.

推荐答案

您必须注册 OnAudioFocusListener 与 AudioManager ：

audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audio.requestAudioFocus(this,
      AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);

的这个参数是实施 OnAudioFocusListener 类的引用。

The this parameter is a reference to the class implementing OnAudioFocusListener.
