我正在尝试在范围内提取YouTube URL.我想在日志中提取我的sparsarray值

Question

在日志中，我想查看数组的结构以及日志中数组的每个索引值。在日志中，我在字符串中打印我的数组值。但是我想使用loop

单独打印索引的每个值

  private void extractYoutubeUrl() {
        new YouTubeExtractor(this) {
            @Override
            public void onExtractionComplete(SparseArray<YtFile> ytFiles, VideoMeta vMeta) {
                //Log.d("======>>>>>>>>>>>>>>>>>", "onExtractionComplete: "+ytFiles.toString());

                Object object = ytFiles.toString();
                Log.d("=====>>>>>", "onExtractionComplete: "+object);
                if (ytFiles != null) {

                    playVideo(ytFiles.get(18).getUrl());

                }
            }
        }.extract(youtubeLink, true, true);
    }
    private void playVideo(String downloadUrl) {
        SimpleExoPlayerView simpleExoPlayer = findViewById(R.id.player);
        simpleExoPlayer.setPlayer(Exoplayer.getSharedInstance(MainActivity.this).getSimpleExoPlayerView().getPlayer());
        Exoplayer.getSharedInstance(MainActivity.this).playStream(downloadUrl);
    }

错误消息如下：

Answer 1

如果我正确理解您，这将有能力：

for(i=0, size = ytFiles.size(); i < size; i++){
    YtFile ytFile = ytFiles.valueAt(i);
    Log.d(TAG, "index: " + i + " path: " + ytFile.getUrl);
    }
