安卓播放器持续回调，缓冲中。

Question

我在应用程序中使用MediaPlayer播放在线mp3文件的音频。

然而，即使播放完成后，控制台仍会显示大量的回调和缓冲。

我尝试在播放器上调用stop()方法，但这只会导致播放器无法正常播放。

我该怎么办？

有什么见解吗？我现在也是这样^^ - Joerg Simon

好的，我认为我解决了我的问题：我愚蠢地忘记设置setOnPreparedListener() o_O。 - Joerg Simon

@JoergSimon我已经设置了setOnprepareListener，但仍然面临相同的问题。 - Ricardo

你解决了吗？我也遇到了这个问题。 - Dragolis

Answer 1

你确定后台没有其他应用在运行吗（比如Pandora）？

我发现你的问题是因为我的Droid手机也在产生同样的logcat消息。后来我意识到我的Pandora应用程序被暂停了，结束应用后，这些消息停止了。

Answer 2

嘿，我也在我的案例中发现了这个问题。

尝试添加一个OnCompletionListener。

voicePlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { mp.stop(); mp.reset(); } });
