【问题描述】：

我有一个从 facebook 页面获取 xml 的应用程序。问题是缺少这部分：

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0"
      xmlns:media="http://search.yahoo.com/mrss/"
      xmlns:dc="http://purl.org/dc/elements/1.1/"

这是 xml 的开头。我是这样得到的：

@Override
        protected Void doInBackground(Void... params) {
            URL url;
            String pageXML = ""; 
            try {
                url = new URL(pageUrl);

                HttpURLConnection urlConnection = (HttpURLConnection) url
                        .openConnection();

                InputStream in = urlConnection.getInputStream();
                streamToString(in);

                Log.i("", pageXML);
            } catch (Exception e) {
                e.printStackTrace();
            }
            return null;
        }

        private void streamToString(InputStream in) throws IOException {
            StringBuilder inputStringBuilder = new StringBuilder();
            BufferedReader bufferedReader = new BufferedReader(
                    new InputStreamReader(in, "UTF-8"));
            String line = bufferedReader.readLine();

            while (line != null) {
                inputStringBuilder.append(line);
                inputStringBuilder.append('\n');
                line = bufferedReader.readLine();
            }

            pageXML = inputStringBuilder.toString();

            Log.i("", pageXML);
            write("interesting_engineering", pageXML);
        }

您知道问题出在哪里吗？ This 是我从中获取 xml 的 url。

【解决方案1】：

我发现了问题。我的代码中有一部分（我在这里删除了）把事情搞砸了。这是导致问题的原因：

        InputStreamReader isw = new InputStreamReader(in);

        int data = isw.read();

        //This line is correct
        streamToString(in);

        while (data != -1) {
            char current = (char) data;
            data = isw.read();
        }
