如何检测，当声音文件完成？ [英] How do you detect when a sound file has finished?

问题描述

我使用的是广播接收器的工作这里面​​code播放声音文件：

I am playing a sound file using this code inside a broadcast receiver activity:

notification.sound = Uri.parse("android.resource://emad.app/raw/seven_chimes");

我想检测时，该文件播放完毕。

I would like to detect when this file has finished playing.

我想这样的一个循环，但我认为这是唯一的好媒体播放器，因为它总是尽管我确信声音文件还在玩= FALSE：

I tried a loop like this but I think this is only good for the media player because it always = false even though I made sure the sound file was still playing:

/*
 * Stay here until the chime sound is finished.
 */
   while (manager.isMusicActive()){
   }

你能告诉我，我应该用manager.isMusicActive什么，而不是（）

Can you show me what I should use instead of manager.isMusicActive()

感谢。

推荐答案

您可以使用的MediaPlayer类，并添加完成监听器被激活时，声音播放完

You can use the MediaPlayer class and add a Completion listener to be activated when the sound finishes playing

MediaPlayer mp = MediaPlayer.create(this,Uri.parse("android.resource://emad.app/raw/seven_chimes"));

mp.setOnCompletionListener(new OnCompletionListener() {

            @Override
            public void onCompletion(MediaPlayer mp) {
                performOnEnd();
            }

            });

    mp.start();
