android - 在Android中添加多个音频文件

Question

我正在使用添加多个音频文件

    try {
        MediaPlayer mp = MediaPlayer.create(context, R.raw.play);
        audioArr[0] = mp;
        mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {

                mp.start();

            }
        });

        mp.prepare();

    } catch (Exception e) {
        e.printStackTrace();
    }

并发布具有以下功能的媒体

for (MediaPlayer media : audioList) {
        if (media != null) {
            if(media.isPlaying())
            media.stop();
            media.release();
            media = null;
        }
    }

因为我无法在我的应用程序中播放多个音频文件，所以第一次使用音频播放时，请引用

试试这个 :

void addSongs()
{
    File songs = new File(sdPath); //sdPath is the path of your audio files

    if(songs.listFiles(new SongFilter()).length > 0)
    {
        for(File file : songs.listFiles(new SongFilter()))

        {
            vector.add(file.getName());
        }

        arrayAdapter.setNotifyOnChange(true); //arrayAdapter Array Adapter
        songList.setAdapter(arrayAdapter); //songList is a ListView
    }
}

SongFilter类是这样的:

class SongFilter implements FilenameFilter
{
    public boolean accept(File dir, String filename) 
    {
        return (filename.endsWith(".mp3"));
    }       
}
