问题描述

我在我的应用程序的资产目录中的多个音频文件。当用户点击一个按钮,我想打这些文件按照一定的顺序,一个接一个。不应该有音频文件之间的任何明显的滞后。什么是实现这一目标的最佳方法?

I have multiple audio files in the assets directory of my application. When the user clicks a button I want to play those files in a certain order, one after the other. There shouldn't be any noticeable lag between the audio files. What is the best approach to achieve this?

我想用的MediaPlayer 对象和 OnCompletionListener 取值。但是,这将意味着我必须创造了很多 OnCompletionListener 的因为我需要知道每一个的音频文件是下一次。我缺少的东西,或是否有更好的方法?

I am thinking of using MediaPlayer objects and OnCompletionListeners. But, that would mean I have to create a lot of OnCompletionListeners because I need to know every time which audio file is next. Am I missing something or is there a better approach?

推荐答案

你是在正确的道路,并不需要很多OnCompletionListener's的。

you are on the right way, don't need a lot of OnCompletionListener´s.

//define a variable to be used as index.
int audioindex = 0;
//Extract the files into an array
String[] files = null;
files = assetManager.list("audiofiles");

在你OnCompletionListener呢。

then in your OnCompletionListener.

 mp.setOnCompletionListener(new OnCompletionListener(){
    // @Override
    public void onCompletion(MediaPlayer arg0) {
    // File has ended, play the next one.
   FunctionPlayFile(files[audioindex]);
   audioindex+=1; //increment the index to get the next audiofile
     }
});
