使用唱片集名称Android获取唱片集艺术

我想在listview中显示具有唱片集名称的唱片集艺术。但我没有办法展示专辑艺术。我已经试过了

这是我的密码：

Cursor cursor = managedQuery(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, null, null, null, null);
          if (cursor == null) 
          {
              //Query Failed , Handle error.
          }
          else if (!cursor.moveToFirst()) 
          {
             //No media on the device.
          }
          else
          {
              int titleColumn = cursor.getColumnIndex(android.provider.MediaStore.Audio.Albums.ALBUM_ART);
              int id = cursor.getColumnIndex(android.provider.MediaStore.Audio.Albums.ALBUM_ID); //here value i m getting -1 .

              for(int i=0;i<cursor.getCount();i++)
              {
                  if(id<0)
                  {
                        Long album =Long.parseLong(cursor.getString(id)); 
                        String coverPath = cursor.getString(titleColumn);

                        Context context = null;
                        ContentResolver res = context.getContentResolver();
                        Uri uri = ContentUris.withAppendedId(sArtworkUri, album);
                        if (uri != null)
                        {
                            InputStream in = null;
                            try
                            {
                                in = res.openInputStream(uri);
                                Bitmap b = BitmapFactory.decodeStream(in, null, sBitmapOptions);
                                ImageView coverAlbum=(ImageView)findViewById(R.id.thumbnail);
                                coverAlbum.setImageBitmap(b);

                            } catch (FileNotFoundException ex)
                            {

                            }

                        }

                  }
                         //code to insert in listview
                  cursor.moveToNext();
               }
           }
           cursor.close();

使用下面的代码获取包含歌曲信息的唱片集艺术。您可以稍微更改，只显示唱片集名称，而不显示歌曲列表
