如何检测播放歌曲完成？ [英] How to detect song playing is completed?

问题描述

我玩一首歌与媒体播放器的帮助下使用以下code，

I am playing a song with the help of Media Player using following code,

mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource( "sound_file_filepath" );
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() 
{
    @Override
    public void onPrepared(MediaPlayer mp) 
    {
        mediaPlayer.start();
    }
}); 

现在我在我的.xml文件切换样的形象它首先显示一个播放图像。点击/触摸播放图像后，它会开始播放歌曲，并替换停止图像的图像。

Now i have a toggle kind of image in my .xml file which first shows a play image. After clicking/touching the play image it will start the song and replace the image with stop image.

现在我的问题是我怎么能知道我的声音播放完毕？我很清楚地知道IsPlaying模块（）方法，它如果歌曲正在运行，如果不是假返回true。但是，当和放大器;我应该在哪里检查此条件，再次显示播放图像？

Now my question is how can i know that my sound has finished playing ? I am very well aware of isPlaying() method, it returns true if song is running and false if not. But when & where should i check this condition to display the play image again ?

推荐答案

我相信这样的事情可以帮忙，

I believe something like this can help,

mediaPlayer.setOnCompletionListener(this);
// When song is ended then media player automatically called onCompletion method.
    public void onCompletion(MediaPlayer arg0) 
{
    // Write your code
}
