Android URL内容到字符串

Question

我想连接到一个网站，过滤一些内容然后把它放在一个字符串中，但我不知道该怎么做。

public void zahlenLaden (View view) throws Exception { 

    URL oracle = new URL("http://www.blabla.de");
    URLConnection yc = oracle.openConnection();
    BufferedReader in = new BufferedReader(
                            new InputStreamReader(
                            yc.getInputStream()));
    String inputLine;

    while ((inputLine = in.readLine()) != null) {
  //What I have to write here?
    }

Answer 1

在while循环之前声明要输出的字符串：

String output = "";

然后在每次迭代中追加到该字符串：

output += inputLine + "\n"; (don't forget the omitted newline)

Answer 2

StringBuilder sb = new StringBuilder();

 while ((inputLine = in.readLine()) != null) {
      sb.append(inputLine + "\n");

    }

然后只做sp.toString();

Answer 3

Nikola的回答是可以的，只是改进了StringBuilder的使用：

StringBuilder sb = new StringBuilder();

 while ((inputLine = in.readLine()) != null) {
      sb.append(inputLine).append("\n");
 }
