获取音频文件的路径问题

Posted 2021-05-03

public void getSongList() {
    //retrieve song info
        ContentResolver musicResolver = getContentResolver();
        musicUri = android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor musicCursor = musicResolver.query(musicUri, null, null, null, null);
        if(musicCursor!=null && musicCursor.moveToFirst()){
            //get columns
            int titleColumn = musicCursor.getColumnIndex
                    (android.provider.MediaStore.Audio.Media.TITLE);
            int idColumn = musicCursor.getColumnIndex
                    (android.provider.MediaStore.Audio.Media._ID);
            int artistColumn = musicCursor.getColumnIndex
                    (android.provider.MediaStore.Audio.Media.ARTIST);
            String UrlColumn = musicCursor.getString(musicCursor.getColumnIndex(MediaStore.MediaColumns.DATA));

            //add songs to list
            do {
                long thisId = musicCursor.getLong(idColumn);
                String thisTitle = musicCursor.getString(titleColumn);
                String thisArtist = musicCursor.getString(artistColumn);
                String musicUriPath=musicUri.getPathSegments().toString();
               // String musicUriPath =UrlColumn;
                songList.add(new Music(thisId, thisTitle, thisArtist,musicUriPath));
            }
            while (musicCursor.moveToNext());
        }
}.   

嗨，我试着开发音乐播放器应用程序。我的积分场景问题是：1）app在listview上显示音频，2）用户可以点击列出元素（对于每个音乐）并添加到创建播放列表（在显示列表之前，在sqlite上创建具有名称和其他属性的播放列表）但是喜欢在这段代码上我无法获得完整路径并保存字符串格式。如何保存，如internalstroge / audio / musicName.mp3，之后我将从listview中选择播放列表并打开播放列表音乐。

谢谢你的帮助
