网上很多上传到java服务器上的，找了好久，找到了上传到php的了，思路跟我当初想的差不多，就是post过去。废话不多说，直接上图看代码。

上传的主要代码：
java代码
private void uploadfile(string uploadurl) { string end = \r\n ; string twohyphens = -- ; string boundary = ****** ; try { url url = new url(uploadurl); httpurlconnection httpurlconnection = (httpurlconnection) url .openconnection(); //http连接 // 设置每次传输的流大小，可以有效防止手机因为内存不足崩溃 httpurlconnection.setchunkedstreamingmode( 128 * 1024 ); // 128k // 允许输入输出流 httpurlconnection.setdoinput( true ); httpurlconnection.setdooutput( true ); httpurlconnection.setusecaches( false ); // 使用post方法 httpurlconnection.setrequestmethod( post ); httpurlconnection.setrequestproperty( connection , keep-alive ); //保持一直连接 httpurlconnection.setrequestproperty( charset , utf-8 ); //编码 httpurlconnection.setrequestproperty( content-type , multipart/form-data;boundary= + boundary); //post传递过去的编码 dataoutputstream dos = new dataoutputstream( httpurlconnection.getoutputstream()); //输出流 dos.writebytes(twohyphens + boundary + end); dos.writebytes( content-disposition: form-data; name=\uploadedfile\; filename=\ + srcpath.substring(srcpath.lastindexof( / ) + 1 ) + \ + end); dos.writebytes(end); fileinputstream fis = new fileinputstream(srcpath); //文件输入流，写入到内存中 byte [] buffer = new byte [ 8192 ]; // 8k int count = 0 ; // 读取文件 while ((count = fis.read(buffer)) != - 1 ) { dos.write(buffer, 0 , count); } fis.close(); dos.writebytes(end); dos.writebytes(twohyphens + boundary + twohyphens + end); dos.flush(); inputstream is = httpurlconnection.getinputstream(); //http输入，即得到返回的结果 inputstreamreader isr = new inputstreamreader(is, utf-8 ); bufferedreader br = new bufferedreader(isr); string result = br.readline(); toast.maketext( this , result, toast.length_long).show(); //将结果输出 dos.close(); is.close(); } catch (exception e) { e.printstacktrace(); settitle(e.getmessage()); } } 因为安卓4.0之后耗时间的操作要求都在非ui线程中操作，即将前面的asynctask拿来用了吧~

在这个类中，将上传的操作放在doinbackground当中，可以有progressdialog显示上传了多少：
java代码
// read file bytesread = fileinputstream.read(buffer, 0 , buffersize); while (bytesread > 0 ) { outputstream.write(buffer, 0 , buffersize); length += buffersize; progress = ( int ) ((length * 100 ) / totalsize); publishprogress(progress); bytesavailable = fileinputstream.available(); buffersize = math.min(bytesavailable, maxbuffersize); bytesread = fileinputstream.read(buffer, 0 , buffersize); } outputstream.writebytes(lineend); outputstream.writebytes(twohyphens + boundary + twohyphens + lineend); publishprogress( 100 ); 还有就是，注意权限哟：
