InputStream超时

Question

有没有办法给InputStream设置超时时间？

我当前的代码是这样的：

public class DownloadFile implements Runnable {
private EventHandler eh;
private String source;
private String destination;

public void run(){
    try {
        Log.d("Download", "Download... " + source);
        URL url = new URL(source);

        URLConnection connection = url.openConnection();
        connection.connect();

        int fileLength = connection.getContentLength();

        InputStream input = new BufferedInputStream(url.openStream());
        OutputStream output = new FileOutputStream(destination + "t");

我认为对于你的需求，你可以使用

HttpURLConnection.setReadTimeout()

请注意，这些链接将对您有所帮助。

您也可以使用计时器，但我认为Handler解决方案是最优雅的。
