Android的 - 如何知道什么时候MediaPlayer正在缓冲 [英] Android - How to tell when MediaPlayer is buffering

问题描述

我一定是在缺少明显的东西在这里，但我似乎无法找到任何东西，让我来决定何时MediaPlayer的是缓冲音频。我在互联网流媒体音频和我想显示一个缓冲的指标，但没有我试图让我知道什么时候中断的MediaPlayer的音频缓冲，所以我不能正常显示缓冲指标。任何线索？

I've got to be missing something obvious here, but I can't seem to find anything to allow me to determine when MediaPlayer is buffering audio. I'm streaming internet audio and I want to display a buffering indicator, but nothing I've tried allows me to know when MediaPlayer interrupts the audio to buffer, so I can't properly display a buffering indicator. Any clues?

推荐答案

@Daniel，每对@ JRL的回答您的评论，你很可能得到这个工作，通过旋转一个线程，并等待超时。

@Daniel, per your comment on @JRL's answer, you could probably get this working by spinning up a thread and waiting for a timeout.

喜欢的东西 DetectBufferTimeout.java （未经测试）会做很好。

Something like DetectBufferTimeout.java (untested) would do nicely.

我做的，但是，一致认为，纺了这个单独的线程是一个黑客攻击的一位。也许 OnBufferingUpdateListener 可以做出保证，如何往往要求 onBufferingUpdate（）无论是否处于缓冲进度的变化已经发生，所以我们可以发现，如果我们得到了相同的数值一遍又一遍。

I do, however, agree that spinning up this separate thread is a bit of a hack. Perhaps OnBufferingUpdateListener could make a guarantee as to how often it calls onBufferingUpdate() regardless of whether a change in the buffering progress has occurred so we can detect if we're getting the same value over and over.
