【问题描述】：

我正在尝试制作一个可以在音乐播放器播放歌曲时显示歌曲内部歌词的 android 应用程序。我不想使用 .lrc 文件。有没有其他选项可以显示歌曲的内部歌词？

以下代码：当音乐播放器播放歌曲时读取动作。我把它放在 onCreate() 中。

    IntentFilter filter = new IntentFilter();

    // Read action when music player changed current song
    // I just try it with stock music player form android

    //Google Android player
    filter.addAction("com.android.music.playstatechanged");
    filter.addAction("com.android.music.playbackcomplete");
    filter.addAction("com.android.music.metachanged");        
    //HTC Music
    filter.addAction("com.htc.music.playstatechanged");
    filter.addAction("com.htc.music.playbackcomplete");
    filter.addAction("com.htc.music.metachanged");      
    //MIUI Player
    filter.addAction("com.miui.player.playstatechanged");
    filter.addAction("com.miui.player.playbackcomplete");
    filter.addAction("com.miui.player.metachanged");        
    //Real
    filter.addAction("com.real.IMP.playstatechanged");
    filter.addAction("com.real.IMP.playbackcomplete");
    filter.addAction("com.real.IMP.metachanged");
    //SEMC Music Player
    filter.addAction("com.sonyericsson.music.playbackcontrol.ACTION_TRACK_STARTED");
    filter.addAction("com.sonyericsson.music.playbackcontrol.ACTION_PAUSED");
    filter.addAction("com.sonyericsson.music.TRACK_COMPLETED");
    filter.addAction("com.sonyericsson.music.metachanged");       
    //rdio
    filter.addAction("com.rdio.android.metachanged");
    filter.addAction("com.rdio.android.playstatechanged");     
    //Samsung Music Player
    filter.addAction("com.samsung.sec.android.MusicPlayer.playstatechanged");
    filter.addAction("com.samsung.sec.android.MusicPlayer.playbackcomplete");
    filter.addAction("com.samsung.sec.android.MusicPlayer.metachanged");
    filter.addAction("com.sec.android.app.music.playstatechanged");
    filter.addAction("com.sec.android.app.music.playbackcomplete");
    filter.addAction("com.sec.android.app.music.metachanged");        
    //Winamp
    filter.addAction("com.nullsoft.winamp.playstatechanged");
    filter.addAction("com.nullsoft.winamp.metachanged");
    //Amazon
    filter.addAction("com.amazon.mp3.playstatechanged");
    filter.addAction("com.amazon.mp3.metachanged"); 
    //Rhapsody
    filter.addAction("com.rhapsody.playstatechanged");
    filter.addAction("com.rhapsody.metachanged");
    //PowerAmp
    filter.addAction("com.maxmpz.audioplayer.playstatechanged");
    filter.addAction("com.maxmpz.audioplayer.metachanged");
    // MyTouch4G
    filter.addAction("com.real.IMP.metachanged");
    //appollo
    filter.addAction("com.andrew.apollo.metachanged");
    //will be added any....

    //scrobblers detect for players (poweramp for example)
    //Last.fm
    filter.addAction("fm.last.android.metachanged");
    filter.addAction("fm.last.android.playbackpaused");
    filter.addAction("fm.last.android.playbackcomplete");
    //A simple last.fm scrobbler
    filter.addAction("com.adam.aslfms.notify.playstatechanged");
    //Scrobble Droid
    filter.addAction("net.jjc1138.android.scrobbler.action.MUSIC_STATUS");


    registerReceiver(mReceiver, filter);
    //scrobbling finished

这里是获取音乐信息（mReceiver）函数

private BroadcastReceiver mReceiver = new BroadcastReceiver() {

       @Override
        public void onReceive(Context context, Intent intent)
        {
        String action = intent.getAction();
        String cmd = intent.getStringExtra("command");
        Log.d("mIntentReceiver.onReceive ", action + " / " + cmd);
        String lyric = intent.getStringExtra("lyric");
        String artist1 = intent.getStringExtra(MediaStore.Audio.AudioColumns.ARTIST);
        String album1 = intent.getStringExtra(MediaStore.Audio.AlbumColumns.ALBUM);
        String track1 = intent.getStringExtra(MediaStore.Audio.AudioColumns.TITLE_KEY);
        Toast.makeText(context, "Command : "+cmd+"\n Artist : "+artist1+"\n Album :"+album1+"\n Track : "+track1+"\n Lyric : "+lyric , Toast.LENGTH_SHORT).show();
        }
};

但是这段代码中的歌词显示为空。有人有解决办法吗？

这可能无法完全回答问题，但我希望它有助于稍微改善您的问题。歌词是一种类似于缩略图的元数据，如果要显示歌曲，则应添加歌词元数据。确保它在那里。
