android java mediaplayer服务-如何知道mediaPlayer是否已准备好? [英] android java mediaplayer Service - how can I know if mediaPlayer is prepared?

问题描述

我使用MediaPlayer控件提供了绑定服务，该控件可以加载和播放音频.但是碰巧的是，有时候mediaPlayer.prepare();的速度不够快，并且并不总是准备播放.

I made a binded service with MediaPlayer controls which loads and play back audio. But as it happens, sometimes mediaPlayer.prepare(); is not fast enough and it's not always prepared to playback.

那么我该如何制作类似myService.prepare()这样的方法，在这里我可以要求MediaPlayer准备并等待它?

So how can I make such method , something like myService.prepare() where I can ask for MediaPlayer to prepare and wait for it?

推荐答案

您可以等待MediaPlayer触发OnPrepared事件.

You may wait for the OnPrepared event to be triggered by the MediaPlayer.

prepare()仅阻止文件，因此，如果您使用其他工具，则可能是原因.

Edit : prepare() is blocking only for files, so if you're working with something else, that might be the cause.
