获取上传进度

本文介绍了获取上传进度的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我的上传方法如下：

private void upload(String Server, String FilePath, String SavePath, String NewName) { String end = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; try { URL url = new URL(ActionUrl); HttpURLConnection con = (HttpURLConnection) url.openConnection(); con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); con.setRequestMethod("POST"); con.setRequestProperty("Connection", "Keep-Alive"); con.setRequestProperty("Accept", "text/*"); con.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); ds = new DataOutputStream(con.getOutputStream()); ds.writeBytes(twoHyphens + boundary + end); ds.writeBytes("Content-Disposition: form-data;" + "name=\"folder\"" + end + end); ds.write(SavePath.getBytes("UTF-8")); ds.writeBytes(end); ds.writeBytes(twoHyphens + boundary + end); ds.writeBytes("Content-Disposition: form-data;" + "name=\"Filedata\"; filename=\""); ds.write(NewName.getBytes("UTF-8")); ds.writeBytes("\"" + end); ds.writeBytes(end); FileInputStream fStream = new FileInputStream(uploadFile); int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int length = -1; while((length = fStream.read(buffer)) != -1) { ds.write(buffer, 0, length); } ds.writeBytes(end); ds.writeBytes(twoHyphens + boundary + twoHyphens + end); fStream.close(); ds.flush(); InputStream is = con.getInputStream(); int ch; StringBuffer b = new StringBuffer(); while((ch = is.read()) != -1) { b.append((char)ch); } System.out.println("UPLOAD" + "SUCCESS"); ds.close(); } catch(Exception e) { e.printStackTrace(); } }

我发现行 InputStream为= con.getInputStream（）; 花大部分的时间。但如何获得它的进步派？或如何修改我的方法的部分上传文件？

I found the line InputStream is = con.getInputStream(); spend most time. But how to get the progress of it send? Or how to modify my method to upload file "by parts"?

推荐答案

您可以尝试以下code，

You can try following code,

先显示一个进度对话框致电上传方法之前，

First display a Progress Dialog Before calling your upload method,

progDailog = ProgressDialog.show(loginAct,"Process ", "please wait....",true,true); new Thread ( new Runnable() { public void run() { // your uploading code goes here } }).start(); Handler progressHandler = new Handler() { public void handleMessage(Message msg1) { progDailog.dismiss(); } }
