我正在实现一个与获取当前音乐曲目信息相关的应用程序。

我正在使用以下代码来获得它：

public class CurrentMusicTrackInfoActivity extends Activity {

    public static final String SERVICECMD = "com.android.music.musicservicecommand";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        IntentFilter iF = new IntentFilter();
        iF.addAction("com.android.music.metachanged");
        iF.addAction("com.android.music.playstatechanged");
        iF.addAction("com.android.music.playbackcomplete");
        iF.addAction("com.android.music.queuechanged");

        registerReceiver(mReceiver, iF);
    }

    private BroadcastReceiver mReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            String cmd = intent.getStringExtra("command");
            Log.v("tag ", action + " / " + cmd);
            String artist = intent.getStringExtra("artist");
            String album = intent.getStringExtra("album");
            String track = intent.getStringExtra("track");
            Log.v("tag", artist + ":" + album + ":" + track);
            Toast.makeText(CurrentMusicTrackInfoActivity.this, track, Toast.LENGTH_SHORT).show();
        }
    };

}

它仅适用于某些手机。我想实现代码以获取所有 Android 设备（例如 HTC 和三星设备）中的当前音乐曲目信息。

有没有办法做到这一点？

检查这是我的应用程序中使用的运行良好的

    iF.addAction("com.android.music.metachanged");

    iF.addAction("com.htc.music.metachanged");

    iF.addAction("fm.last.android.metachanged");
    iF.addAction("com.sec.android.app.music.metachanged");
    iF.addAction("com.nullsoft.winamp.metachanged");
    iF.addAction("com.amazon.mp3.metachanged");     
    iF.addAction("com.miui.player.metachanged");        
    iF.addAction("com.real.IMP.metachanged");
    iF.addAction("com.sonyericsson.music.metachanged");
    iF.addAction("com.rdio.android.metachanged");
    iF.addAction("com.samsung.sec.android.MusicPlayer.metachanged");
    iF.addAction("com.andrew.apollo.metachanged");

这可能会有所帮助。我用它来获取我的一个应用程序中的音频文件的元数据：

String scheme = mAudioUri.getScheme();
String title = "";
String artist = "";
if(scheme.equals("content")) {
    String[] proj = {MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.ARTIST};
    Cursor cursor = this.getContentResolver().query(mAudioUri, proj, null, null, null);
    if(cursor != null && cursor.getCount() > 0) {
        cursor.moveToFirst();
        if(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE) != -1) {  
            title = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE));
            artist = cursor.getString(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST));
        }
    }
}

MediaStore.Audio.Media 类中有很多列，您可以使用它们来查找我认为的所需内容。

Amazon MP3（Build 2.8.1）似乎在附加内容前加上 com.amazon.mp3 所以对于 com.amazon.mp3.metachanged 我使用了：

    String artist = "";
    String track = "";
    if (action.equals("com.amazon.mp3.metachanged")) {
        artist = intent.getStringExtra("com.amazon.mp3.artist");
        track = intent.getStringExtra("com.amazon.mp3.track");
    } else {
        artist = intent.getStringExtra("artist");
        track = intent.getStringExtra("track");

    }

这对于检查额外名称很方便：

    Set<String> extrasList = intent.getExtras().keySet();

    for (String str : extrasList) {
        Log.d(TAG, str);
    }
