android – 如何从字节数组上传数据到PHP服务器上传进度？

最后,我做到了.我在AsyncTask类中使用file-input / output-stream完成了这个.下面,我已经给出了上传文件和代码的代码.显示正在进行中……

class ImageUploadTask extends AsyncTask<Void,Void,String> {

    @Override
    protected void onPreExecute() {
        pb.setVisibility(View.VISIBLE);

    }


    @Override
    protected String doInBACkground(Void... unused) {

        String twoHyphens = "--";
        String boundary = "*****" + Long.toString(System.currentTimeMillis()) + "*****";
        String lineEnd = "\r\n";

        try
        {
            FileInputStream fileInputStream = new FileInputStream(new     File(pathToOurFilE));

            URL url = new URL(urlServer);
            connection = (httpURLConnection) url.openConnection();

            // Allow Inputs & Outputs
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.setUseCaches(false);

            // Enable POST method
            connection.setrequestMethod("POST");

            connection.setrequestProperty("Connection","Keep-Alive");
            connection.setrequestProperty("Content-Type","multipart/form-data;boundary="+boundary);

            outputStream = new DataOutputStream(     connection.getOutputStream() );
            outputStream.writeBytes(twoHyphens + boundary + lineEnd);
            outputStream.writeBytes("Content-Disposition: form-data;     name=\"image\";filename=\"" + pathToOurFile +"\"" + lineEnd);
            outputStream.writeBytes(lineEnd);

            bytesAvailable = fileInputStream.available();
            Log.v("Size",bytesAvailable+"");

            pb.setProgress(0);
            pb.setMax(bytesAvailablE);
            //Log.v("Max",pb.getMax()+"");

            bufferSize = Math.min(bytesAvailable,maxBufferSizE);
            buffer = new byte[bufferSize];


            // Read file
            bytesRead = fileInputStream.read(buffer,bufferSizE);

            while (bytesRead > 0)
            {
                outputStream.write(buffer,bufferSizE);

                bytesAvailable = fileInputStream.available();
                Log.v("Available",bytesAvailable+"");

                publishProgress();

                bufferSize = Math.min(bytesAvailable,maxBufferSizE);
                bytesRead = fileInputStream.read(buffer,bufferSizE);
            }

            outputStream.writeBytes(lineEnd);
            outputStream.writeBytes(twoHyphens + boundary + twoHyphens     + lineEnd);

            // Responses from the server (code and messagE)
            serverResponseCode = connection.getResponseCode();
            serverResponsemessage = connection.getResponsemessage();
            System.out.println(serverResponsemessagE);

            fileInputStream.close();
            outputStream.flush();
            outputStream.close();

        }
        catch (Exception eX)
        {
        //Exception handling
        }

        //publishProgress();

        return null;

    }

    @Override
    protected void onProgressupdate(Void... unsued) {
        super.onProgressupdate(unsued);

        pb.setProgress(pb.getMax()-bytesAvailablE);

    }

    @Override
    protected void onPostExecute(String sResponsE) {

        //if(pb.getProgress()>= pb.getMax())
        pb.setVisibility(View.INVISIBLE);

    }
}
