如何访问Android的默认提示音？ [英] How do I access Android's default beep sound?

问题描述

我想提出一个按钮，播放蜂鸣声，以表明它已经pssed $ P $。我想知道如何使用默认的Andr​​oid提示音（比如当您调整铃声音量），而不是导入自己的MP3音乐文件，或使用ToneGenerator？

解决方案

 公共无效playSound（上下文的背景下）抛出：IllegalArgumentException  - ，
                                              SecurityException异常，
                                              IllegalStateException异常，
                                              IOException异常{

    乌里soundUri = RingtoneManager.getDefaultUri（RingtoneManager.TYPE_NOTIFICATION）;
    MediaPlayer的mMediaPlayer =新的MediaPlayer（）;
    mMediaPlayer.setDataSource（背景下，soundUri）;
    最后AudioManager audioManager =（AudioManager）context.getSystemService（Context.AUDIO_SERVICE）;

    如果（audioManager.getStreamVolume（AudioManager.STREAM_ALARM）！= 0）{
        mMediaPlayer.setAudioStreamType（AudioManager.STREAM_ALARM）;
        mMediaPlayer.setLooping（真正的）;
        mMediaPlayer prepare（）。
        mMediaPlayer.start（）;
    }
}
 

我发现了另一个答案：

 尝试{
    URI通知= RingtoneManager.getDefaultUri（RingtoneManager.TYPE_NOTIFICATION）;
    铃声R = RingtoneManager.getRingtone（getApplicationContext（），通知）;
    r.play（）;
}赶上（例外五）{
    e.printStackTrace（）;
}

I would like to make a button play a beep sound to indicate it has been pressed. I want to know how to use the default android beep sound (like when you adjust the ringer volume), instead of importing my own mp3 music file or using ToneGenerator?

解决方案

public void playSound(Context context) throws IllegalArgumentException, 
                                              SecurityException, 
                                              IllegalStateException,
                                              IOException {

    Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    MediaPlayer mMediaPlayer = new MediaPlayer();
    mMediaPlayer.setDataSource(context, soundUri);
    final AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

    if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
        mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
        mMediaPlayer.setLooping(true);
        mMediaPlayer.prepare();
        mMediaPlayer.start();
    }
}

I found another answer:

try {
    Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
    r.play();
} catch (Exception e) {
    e.printStackTrace();
}
