如何从http://gdata.youtube.com/feeds/api/playlists/EL5BQGc0nPiVI?v=2&alt=json获取视频列表
我已经制作了一个程序,我可以在其中使用这种 URL 获取视频列表:请检查这个,但这次我想在 Android 中使用 Playlist 获取视频列表,就像使用这个URL 一样,实际YouTube 视频网址:
在这里,我使用的是 JSON,但现在我不知道我需要对代码进行哪些更改才能使用上述播放列表 URL 获取视频列表。
@Override
public void run() {
try {
HttpClient client = new DefaultHttpClient();
HttpUriRequest request = new HttpGet("http://gdata.youtube.com/feeds/api/playlists/EL5BQGc0nPiVI?v=2&alt=json");
// Get the response that YouTube sends back
HttpResponse response = client.execute(request);
// Convert this response into a readable string
String jsonString = StreamUtils.convertToString
(response.getEntity().getContent());
// Create a JSON object that we can use from the String
JSONObject json = new JSONObject(jsonString);
// Get is search result items
JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items");
// Create a list to store are videos in
List<Video> videos = new ArrayList<Video>();
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
// The title of the video
String title = jsonObject.getString("title");
String url;
try {
url = jsonObject.getJSONObject("player").getString("default");
} catch (JSONException ignore) {
url = jsonObject.getJSONObject("player").getString("default");
}
String thumbUrl = jsonObject.getJSONObject("thumbnail").getString("sqDefault");
videos.add(new Video(title, url, thumbUrl));
}
Library lib = new Library(username, videos);
Bundle data = new Bundle();
data.putSerializable(LIBRARY, lib);
Message msg = Message.obtain();
msg.setData(data);
replyTo.sendMessage(msg);
} catch (ClientProtocolException e) {
Log.e("Feck", e);
} catch (IOException e) {
Log.e("Feck", e);
} catch (JSONException e) {
Log.e("Feck", e);
}
}
