android - 互联网连接丢失时不停止读取 Inputstream

Question

我正在使用异步任务下载文件。它正常工作，直到我关闭我的 android 的 wifi 连接(没有其他互联网连接)，下载对话框仍然没有变化。当我查看日志时，我发现 inputstream 的函数 read() 是不停的。那么如何检查这种情况呢？这是我的代码:

URL url = new URL(this.url);
        URLConnection connection = url.openConnection();
        connection.setReadTimeout(1000);
        connection.connect();
        // this will be useful so that you can show a typical 0-100% progress bar
        int fileLength = connection.getContentLength();
        fileName = "temp.zip";

        // download the file
        InputStream input = new BufferedInputStream(connection.getInputStream());
        OutputStream output = new FileOutputStream(path+fileName);

        byte buffer[] = new byte[1024000];
        long total = 0;
        int count;
        Log.v("test download:","download in background");
        while (((count = input.read(buffer)) != -1)) {
            Log.v("test download:","read:"+count);
            total += count;
            publishProgress((int) (total * 100 / fileLength - 1));
            output.write(buffer, 0, count);
        }

因为您已经通过调用 setReadTimeout() 设置了超时，您应该在连接断开后不久收到 SocketTimeoutException。

您的代码是否碰巧可以静默捕获此异常？
