我一直在到处寻找如何在 Android 中播放铃声/闹钟声音.

I have been looking everywhere how to play a ringtone/alarm sound in Android.

我按下一个按钮，我想播放铃声/闹钟声音.我找不到简单直接的示例.是的，我已经看过闹钟源代码了...但它并不简单，我无法编译它.

I press a button and I want to play a ringtone/alarm sound. I could not find an easy, straightforward sample. Yes, I already looked at Alarm clock source code... but it is not straightforward and I cannot compile it.

我无法完成这项工作:

Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(this, alert); final AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE); if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) { player.setAudioStreamType(AudioManager.STREAM_ALARM); player.setLooping(true); player.prepare(); player.start(); }

我收到此错误:

04-11 17:15:27.638: ERROR/MediaPlayerService(30): Couldn't open fd for content://settings/system/ringtone

所以.. 如果有人知道如何播放默认铃声/闹钟，请告诉我.

So.. please if somebody knows how to play a default ringtone/alarm let me know.

我不想上传任何文件.只需播放默认铃声.

I prefer not to upload any file. Just play a default ringtone.

推荐答案

你可以简单地播放一个设置好的铃声:

You can simply play a setted ringtone with this:

Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification); r.play();
