我正在尝试获取项目列表以形成播放列表,并且我只能检索其中一个项目。这是我要进入recyclerview的bindView的代码:
@Override
public void onBindViewHolder(PlaylistViewHolder holder, int position)
{
try
{
String url = "https://www.c895.org/playlist";
Document document = Jsoup.connect(url).get();
Element playlist = document.select("#playlist").first();
List<TrackInfo> tracks = new ArrayList<>();
for(Element track : playlist.children())
{
long time = Long.parseLong(track.dataset().get("ts"));
String title = track.select(".title").text();
String artist = track.select(".artist").text();
tracks.add(new TrackInfo(new Date(time * 1000), title, artist));
}
for(int i = 0; i < tracks.size() - 1; i++)
{
holder.titlesView.setText(tracks.get(i).toString());
}
}
catch(IOException e)
{
e.printStackTrace();
}
}
理想情况下,我想获得10到20个结果。反正我能做到吗?
答案 0 :(得分:1)
这是因为您所需的html部分在以下标记中:
<div id="playlist">
</div>
因此您不能使用以下内容:
Element playlist = document.select("#playlist").first();
但是您需要使用div#playlist
来获取所有播放列表项:
Element playlist = document.select("div#playlist");
