我尝试播放设备铃声一次用的MediaPlayer类（我有我在我的应用程序与其他音源使用的铃声一起使用的MediaPlayer），所以我尝试以下玩随机铃声但我不能停止它的循环，它不断播放。是否有可能发挥的铃声只有一个时间的MediaPlayer。

I try to play a device ringtone one time with the MediaPlayer class (I have to use MediaPlayer as I use the ringtones together with other audio sources in my app) So i try the following to play a random ringtone yet I cant stop it looping, it keeps playing. Is it possible to play a ringtone only one time with MediaPlayer.

感谢

try {
    RingtoneManager mRing = new RingtoneManager(RingtoneActivity.this);
    int mNumberOfRingtones = mRing.getCursor().getCount();
    Uri mRingToneUri = mRing.getRingtoneUri((int) (Math.random() * mNumberOfRingtones));
    mMediaPlayer = new MediaPlayer();
    mMediaPlayer.setDataSource(RingtoneActivity.this, mRingToneUri);
    mMediaPlayer.prepare();
    mMediaPlayer.setLooping(false);
    mMediaPlayer.start();

} catch (Exception ignore) {
}

我发现使用事件简单的解决方案 - 确认的答案，因为它可以解决你的问题：）

I found simple solution with use events - confirm answer since it solves your problem :)

mediaPlayer.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() {
                    @Override
                    public void onSeekComplete(MediaPlayer mediaPlayer) {
                        mediaPlayer.stop();
                    }
                });

记住版本（）。

            mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                @Override
                public void onCompletion(MediaPlayer mediaPlayer) {
                    mediaPlayer.release();
                }
            });

全部code它你想使用需要设置铃声的东西，你会喜欢什么。

Full code it your want to use need set ring tone to something what you would like.

        AudioManager audioManager = (AudioManager)getSystemService(AUDIO_SERVICE);
        int volume = audioManager.getStreamVolume(AudioManager.STREAM_NOTIFICATION);
        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(view.getContext());
        Uri notificationSoundUri = Uri.parse(prefs.getString("notification_sound", "DEFAULT_SOUND"));

        MediaPlayer mediaPlayer = new MediaPlayer();
        try {
            mediaPlayer.setDataSource(view.getContext(), notificationSoundUri);
        } catch (Exception e1) {
            e1.printStackTrace();
            mediaPlayer.release();
            return;
        }
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);
        mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mediaPlayer) {
                mediaPlayer.release();
            }
        });
        try {
            mediaPlayer.prepare();
        } catch (Exception e1) {
            e1.printStackTrace();
            mediaPlayer.release();
            return;
        }
        mediaPlayer.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() {

            @Override
            public void onSeekComplete(MediaPlayer mediaPlayer) {
                // TODO Auto-generated method stub
                mediaPlayer.stop();
                mediaPlayer.start();
            }
        });
        mediaPlayer.setVolume(volume, volume);
        mediaPlayer.start();
