如何一个接一个播放音频文件 [英] How to play audio files one after the other

问题描述

我的应用程序的资产目录中有多个音频文件.当用户单击一个按钮时，我想按特定顺序播放这些文件，一个接一个.音频文件之间不应该有任何明显的延迟.实现这一目标的最佳方法是什么?

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?

我正在考虑使用 MediaPlayer 对象和 OnCompletionListeners.但是，这意味着我必须创建很多 OnCompletionListener ，因为我每次都需要知道下一个音频文件.我是否遗漏了什么或有更好的方法?

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

你走在正确的道路上，不需要很多 OnCompletionListener.

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");

然后在您的 OnCompletionListener 中.

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
     }
});
