流源上的MediaMetadataRetriever

问题描述

我很难显示来自流媒体源的当前曲目播放.使用MediaMetaDataRetriever类返回NULL，表示失败.我写了一个简单的方法，但是现在我倾向于认为这仅适用于MP3，WMA，AVI等媒体文件.

I am having a tough time displaying the current track playing from a streaming source. Using MediaMetaDataRetriever class returns a NULL, meaning it failed. I wrote a simple method but now I'm inclining to think this only works on media files like MP3, WMA, AVI, etc.

public void metaData(){
        mmr.setDataSource(urlStation);
        String metaD = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ALBUMARTIST);
        Toast.makeText(MainActivity.this, "Artist = " + metaD, Toast.LENGTH_LONG).show();

任何好的和简单的建议将不胜感激.谢谢您的时间！

Any good and easy recommandations would be greatly appreciated. Thank you for your time!
