推荐答案

您可以使用内容提供商这一点。

You can use content provider for this.

希望这code可以帮助你启动。

Hope this code may help you to start up.

final Cursor mCursor = getContentResolver().query(
                MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
                new String[] { MediaStore.Audio.Media.DISPLAY_NAME,
                        MediaStore.Audio.Media.DATA,
                        MediaStore.Audio.Media.ARTIST,
                        MediaStore.Audio.Media.ALBUM_ID }, null, null,
                "LOWER(" + MediaStore.Audio.Media.TITLE + ") ASC");

        int count = mCursor.getCount();

        String[] songs = new String[count];

        if (mCursor.moveToFirst()) {
            do {
                String songname = mCursor
                        .getString(mCursor
                                .getColumnIndexOrThrow(MediaStore.Audio.Media.DISPLAY_NAME));
                String sonpath = mCursor.getString(mCursor
                        .getColumnIndexOrThrow(MediaStore.Audio.Media.DATA));
                String artistname = mCursor.getString(mCursor
                        .getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST));
                String albumid = mCursor
                        .getString(mCursor
                                .getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID));
    } while (mCursor.moveToNext());
            Constant.sdCardmusic = allsongs;
        }

        mCursor.close();
 }

如果你想获得相册图片，那么你可以通过相册ID从上面code进入下面的方法：

If you want to get album picture then you can pass album id getting from above code into below method:

private Bitmap getArtistImage(String albumid) {
        Bitmap artwork = null;
        try {
            Uri sArtworkUri = Uri
                    .parse("content://media/external/audio/albumart");
            Uri uri = ContentUris.withAppendedId(sArtworkUri,
                    Long.valueOf(albumid));
            ContentResolver res = mContext.getContentResolver();
            InputStream in = res.openInputStream(uri);
            artwork = BitmapFactory.decodeStream(in);

        } catch (Exception e) {
            Log.e("Exception", e.toString());
        }
        return artwork;
    }
