如何检测歌曲播放完成? [英] How to detect song playing is completed?

问题描述

我正在使用以下代码在媒体播放器的帮助下播放歌曲，

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();
    }
}); 

现在我的 .xml 文件中有一个切换类型的图像，它首先显示一个播放图像.单击/触摸播放图像后，它将开始播放歌曲并将图像替换为停止图像.

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知道我的声音已经播放完毕?我非常清楚 isPlaying() 方法，如果歌曲正在运行，它返回 true，否则返回 false.但是当 &我应该在哪里检查这个条件以再次显示播放图像?

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

我相信这样的事情会有所帮助，

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
}
