setReadTimeout或setConnectTimeout的实现方式和位置？在编译之前，我的测试总是抛出未定义的错误

当没有连接时，它会在in.readLine（）处阻塞，应用程序将永远等待

try {
    URL url = new URL("http://mydomain/myfile.php");

    //url.setReadTimeout(5000); does not work

    InputStreamReader testi= new InputStreamReader(url.openStream());
    BufferedReader in = new BufferedReader(testi);

        //in.setReadTimeout(5000); does not work

    stri = in.readLine();   
    Log.v ("GotThat: ",stri);
    in.close();
} catch (MalformedURLException e) {
} catch (IOException e) {
}

谢谢你的帮助

chris使用URL连接

 URL url = new URL("http://mydomain/myfile.php");
 URLConnection connection = url.openConnection()
 int timeoutMs = 2000;
 connection.setReadTimeout(timeoutMs );

 InputStream urlInputStream = connection.getInputStream();
 BufferedReader in = new BufferedReader(new InputStreamReader(urlInputStream));

 String firstLine = in.readLine();   
 System.out.println("GotThat: " + firstLine);
 in.close();

这对我有用。由于你的评论christian Muller，我在几个网站上试用了它，并调整了

timeoutMs

值。将

timeoutMs

设置为250 ms会导致

SocketTimeoutException

。如果你一步一步地增加它，你会看到最后你读了一行

例如，如果我尝试：

URL url = new URL("http://msdn.microsoft.com/en-US/");
URLConnection connection = url.openConnection();
int timeoutMs = 250;
connection.setReadTimeout(timeoutMs);

我明白了

如果我对550

timeoutMs

进行同样的尝试，它会起作用：

 GotThat: <!DOCTYPE html>

明白了：

使用URL连接

 URL url = new URL("http://mydomain/myfile.php");
 URLConnection connection = url.openConnection()
 int timeoutMs = 2000;
 connection.setReadTimeout(timeoutMs );

 InputStream urlInputStream = connection.getInputStream();
 BufferedReader in = new BufferedReader(new InputStreamReader(urlInputStream));

 String firstLine = in.readLine();   
 System.out.println("GotThat: " + firstLine);
 in.close();
