‘壹’ 如何实现在Android文件上传进度条

实现在android实现带进度条的上传效果效果如图: 用到以下两个类就可实现带进度条的文件上传: 1、CustomMultiPartEntity extends MultipartEntity, 2、HttpMultipartPost extends AsyncTask 代码如下: import java/UploadImage.php"); try{ = newCustomMultipartEntity( newProgressListener() { @Override public void transferred(longnum){ publishProgress((int) ((num / (float) totalSize) * 100)); } }); // We use FileBody to transfer an image multipartContent.addPart("uploaded_file", newFileBody( newFile(m_userSelectedImagePath))); totalSize= multipartContent.getContentLength(); // Send it httpPost.setEntity(multipartContent); HttpResponseresponse = httpClient.execute(httpPost, httpContext); String serverResponse = EntityUtils.toString(response.getEntity()); ResponseFactoryrp = newResponseFactory(serverResponse); return(TypeImage) rp.getData(); } catch(Exception e) { System.out.println(e); } returnnull; } @Override protectedvoidonProgressUpdate(Integer... progress){ pd.setProgress((int) (progress[0])); } @Override protectedvoidonPostExecute(TypeUploadImageui) { pd.dismiss(); } } 在 transferred()函数中调用publishProgress((int) ((num / (float) totalSize) * 100)); 在onProgressUpdate()实现上传进度的更新操作

‘贰’ 抖音发图片下面带进度条的怎么弄

摘要 首先我们打开抖音,打开有进度条的视频,点击下方的白色进度条线,进行拉动即可调整进度。抖音让每一个人看见并连接更大的世界,鼓励表达、沟通和记录,激发创造,丰富人们的精神世界。

‘叁’ 谁懂如何写html5带有进度条的图片上传的代码吗

可以自己用div画一个啊,父子div,父div宽度固定,子div随着进度宽度动态改变。子div设置背景颜色

‘肆’ asp 如何实现带进度条的上传文件功能

以下就以abcupload4为例来说明怎么来制作实时的文件上传进度条。

(注:我们在abcupload自带例子基础上改进。)

progressupload.htm(上传文件的前台提交,我们让进度条在这个里面显示)

<HTML>

<body>

<script language="javascript">

<!--

theUniqueID = (new Date()).getTime() % 1000000000;

function s() //让数据提交的同时执行显示进度条的函数

{

bar(); //开始执行反映上传情况的函数

document.myform.action = "progressupload.ASP?ID=" theUniqueID; //处理上传数据的程序

document.myform.target="up" //将提交的数据放在一个名字是up隐藏的iframe里面处理,这样提交的页面就不会跳转到处理数据的页

document.myform.submit(); //提交表单

}

function bar()

{

bar1.style.display=''; //让显示上传进度显示的层的可见

var timeoutid=null; //这个变量是作定时器的ID

var oXMLDoc = new ActiveXObject('MSXML'); //创建'MSXML'对象

sURL = "progressbar.ASP?ID=" theUniqueID "&temp=" Math.random(); //获取上传状态数据的地址

oXMLDoc.url = sURL; //load数据

var oRoot=oXMLDoc.root; //获取返回XML数据的根节点

if(oRoot.children != null)

{

if (oRoot.children.item(0).text-100==0) //文件上传结束就取消定时器

clearTimeout(timeoutid)

PercentDone.style.width=oRoot.children.item(0).text "%"; //设置进度条的百分比例

//根据返回的数据在客户端显示

min.innerHTML=oRoot.children.item(1).text; //显示剩余时间(分钟)

secs.innerHTML=oRoot.children.item(2).text; //显示剩余时间(秒钟)

BytesDone.innerHTML=oRoot.children.item(3).text; //已上传数据大小

BytesTotal.innerHTML=oRoot.children.item(4).text; //总大小

BytesPerSecond.innerHTML=oRoot.children.item(5).text; //传输速率

Information.innerHTML=oRoot.children.item(6).text; //上传信息

}

if (oRoot.children.item(0).text-100<0) //只要文件没有传完,就每隔多少时间获取一次数据

timeoutid = setTimeout("bar()",50) //这里设定时间间隔是0.05秒,你也可以根据你的情况修改获取数据时间间隔

}

//-->

</script>

‘伍’ 百度贴吧上传图片进度条老是卡在中间,很慢!

你好,这个很可能是网络原因,建议您关闭网页重新上传。或者使用其他浏览器试试。

‘陆’ 如何实现上传文件带进度条

我给你提供思路,自己去实现。 1、你用的是SSH框架,spring有一个MultipartFile技术,支持单文件和多文件上传 2、下载直接用BufferedInputStream+BufferedOutputStream去实现就可以了。

‘柒’ java带参带进度条(真实)上传文件代码

思路如下:


public class MyClass extends Thread {

public JProgressBar bar = new JProgressBar();//进度条
public OutputStream os;// 通向服务器的流
public InputStream is;// 你的文件流
public long len;// 你文件的总长度

public void run() {

byte[] buff = new byte[1024];
long passedlen = 0;
try {
int mark = 0;
while (true) {
mark = is.read(buff, 0, 1024);
os.write(buff, 0, mark);
// 更新进度
passedlen += mark;
int prog = (int) ((double) passedlen / (len == 0 ? 1 : len) * 100);
// 改变进度条的value值
bar.setValue(prog);
// 结束判定
if (passedlen == len) {
break;
}
}
os.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}


‘捌’ asp.net 用fileupload控件实现多图片上传带进度条

这个你要用ajax来实现最好,或者是updataplan空间来实现也可以

‘玖’ 怎样实现在android实现带进度条的上传效果

实现在android实现带进度条的上传效果效果如图:


用到以下两个类就可实现带进度条的文件上传:


1、CustomMultiPartEntity extends MultipartEntity,


2、HttpMultipartPost extends AsyncTask


代码如下:


import java.io.FilterOutputStream;


import java.io.IOException;


import java.io.OutputStream;


import java.nio.charset.Charset;


import org.apache.http.entity.mime.HttpMultipartMode;


import org.apache.http.entity.mime.MultipartEntity;



public class CustomMultipartEntity extends MultipartEntity {


private final ProgressListener listener;


public CustomMultipartEntity(final ProgressListener listener) {


super();


this.listener = listener;


}


public CustomMultipartEntity(final HttpMultipartMode mode, final ProgressListener listener) {


super(mode);


this.listener = listener;


}


public CustomMultipartEntity(HttpMultipartMode mode, final String boundary,


final Charset charset, final ProgressListener listener) {


super(mode, boundary, charset);


this.listener = listener;


}


@Override


public void writeTo(final OutputStream outstream) throws IOException {


super.writeTo(new CountingOutputStream(outstream, this.listener));


}


public static interface ProgressListener {


void transferred(long num);


}



public static class CountingOutputStream extends FilterOutputStream {


private final ProgressListener listener;


private long transferred;


public CountingOutputStream(final OutputStream out, final ProgressListener listener) {


super(out);


this.listener = listener;


this.transferred = 0;


}


public void write(byte[] b, int off, int len) throws IOException {


out.write(b, off, len);


this.transferred += len;


this.listener.transferred(this.transferred);


}


public void write(int b) throws IOException {


out.write(b);


this.transferred++;


this.listener.transferred(this.transferred);


}


}


}


该类计算写入的字节数,我们需要在实现ProgressListener中的trasnfered()方法,更行进度条



public class HttpMultipartPost extends AsyncTask<HttpResponse, Integer, TypeUploadImage> {



ProgressDialogpd;



longtotalSize;



@Override


protectedvoidonPreExecute(){


pd= newProgressDialog(this);


pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);


pd.setMessage("Uploading Picture...");


pd.setCancelable(false);


pd.show();


}



@Override


(HttpResponse... arg0) {


HttpClienthttpClient = newDefaultHttpClient();


HttpContexthttpContext = newBasicHttpContext();


HttpPosthttpPost = newHttpPost("http://herpderp.com/UploadImage.php");



try{


= newCustomMultipartEntity(


newProgressListener() {



@Override


public void transferred(longnum){


publishProgress((int) ((num / (float) totalSize) * 100));


}


});



// We use FileBody to transfer an image


multipartContent.addPart("uploaded_file", newFileBody(


newFile(m_userSelectedImagePath)));


totalSize= multipartContent.getContentLength();



// Send it


httpPost.setEntity(multipartContent);


HttpResponseresponse = httpClient.execute(httpPost, httpContext);


String serverResponse = EntityUtils.toString(response.getEntity());



ResponseFactoryrp = newResponseFactory(serverResponse);


return(TypeImage) rp.getData();


}



catch(Exception e) {


System.out.println(e);


}


returnnull;


}



@Override


protectedvoidonProgressUpdate(Integer... progress){


pd.setProgress((int) (progress[0]));


}



@Override


protectedvoidonPostExecute(TypeUploadImageui) {


pd.dismiss();


}


}

在 transferred()函数中调用publishProgress((int) ((num / (float) totalSize) * 100));


在onProgressUpdate()实现上传进度的更新操作

‘拾’ 寻一个带进度条的上传程序

基于AJAX的WEB上传程序,JSP环境,一次可上传多个文件,带进度条控制,单个文件最大可上传100M文件。
