So zeigen Sie den Fortschrittsbalken beim Hochladen mit Prozentsatz an

Ich lade Video und Foto hoch und es funktioniert einwandfrei. Jetzt möchte ich den Fortschrittsbalken beim Hochladen von Daten mit Prozentsatz anzeigen. Ich habe die Referenz von Android Hive genommen und es wurde in @ implementier httpclient und ich habe es entsprechend geändert httpurlconnection. Jede Hilfe wird geschätzt. Vielen Dank.

Dies ist meine Hauptaktivität, in der die asynchrone Aufgabe ausgeführt wird.

protected void onProgressUpdate(Integer... progress) {
        // Making progress bar visible
        progressBar.setVisibility(View.VISIBLE);

        // updating progress bar value
        progressBar.setProgress(progress[0]);

        // updating percentage value
        txtPercentage.setText(String.valueOf(progress[0]) + "%");
    }

    @Override
    protected String doInBackground(Void... params) {
        return uploadFile();
    }

    @SuppressWarnings("deprecation")
    private String uploadFile() {
        String responseString = null;
            String charset = "UTF-8";
            String requestURL = "YOUR_URL";

            VideoUpload multipart = null;
            try {
                multipart = new VideoUpload(Config.FILE_UPLOAD_URL, charset);
            } catch (IOException e) {
                e.printStackTrace();
            }

        {
            //========================================================
            AndroidMultiPartEntity entity = new AndroidMultiPartEntity(
                    new AndroidMultiPartEntity.ProgressListener() {

                        @Override
                        public void transferred(long num) {
                            publishProgress((int) ((num / (float) totalSize) * 100));
                        }
                    });
            //========================================================
            multipart.addFormField("website", "www.androidhive.info");
            multipart.addFormField("email", "[email protected]");
            try {
                multipart.addFilePart("image", new File(filePath));
            } catch (IOException e) {
    ,            e.printStackTrace();
            }

            try {
                List<String> response = multipart.finish(); // response from server.
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        return responseString;
    }

    @Override
    protected void onPostExecute(String result) {
        Log.e(TAG, "Response from server: " + result);

        // showing the server response in an alert dialog
        showAlert(result);

        super.onPostExecute(result);
    }

}

dies ist meine Uploding-Klasse für httpurlconnections und ihre Funktionsweise.

public VideoUpload(String requestURL, String charset)
        throws IOException {
    this.charset = charset;

    // creates a unique boundary based on time stamp
    boundary = "===" + System.currentTimeMillis() + "===";

    URL url = new URL(requestURL);
    httpConn = (HttpURLConnection) url.openConnection();
    httpConn.setUseCaches(false);
    httpConn.setDoOutput(true); // indicates POST method
    httpConn.setDoInput(true);
    httpConn.setRequestProperty("Content-Type",
            "multipart/form-data; boundary=" + boundary);
    httpConn.setRequestProperty("User-Agent", "CodeJava Agent");
    httpConn.setRequestProperty("Test", "Bonjour");
    outputStream = httpConn.getOutputStream();
    writer = new PrintWriter(new OutputStreamWriter(outputStream, charset),
            true);
}

/**

public void addFormField(String name, String value) {
    writer.append("--" + boundary).append(LINE_FEED);
    writer.append("Content-Disposition: form-data; name=\"" + name + "\"")
            .append(LINE_FEED);
    writer.append("Content-Type: text/plain; charset=" + charset).append(
            LINE_FEED);
    writer.append(LINE_FEED);
    writer.append(value).append(LINE_FEED);
    writer.flush();
}

/**

public void addFilePart(String fieldName, File uploadFile)
        throws IOException {
    String fileName = uploadFile.getName();
    writer.append("--" + boundary).append(LINE_FEED);
    writer.append(
            "Content-Disposition: form-data; name=\"" + fieldName

            .append(LINE_FEED);
    writer.append(

                    + URLConnection.guessContentTypeFromName(fileName))

    writer.append(LINE_FEED);
    writer.flush();

    FileInputStream inputStream = new FileInputStream(uploadFile);
    byte[] buffer = new byte[4096];
    int bytesRead = -1;
    while ((bytesRead = inputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, bytesRead);
    }
    outputStream.flush();
    inputStream.close();

    writer.append(LINE_FEED);
    writer.flush();
}

/**

 */
public void addHeaderField(String name, String value) {

    writer.flush();
}

/**

    List<String> response = new ArrayList<String>();

    writer.append(LINE_FEED).flush();

    writer.close();

    // checks server's status code first
    int status = httpConn.getResponseCode();
    if (status == HttpURLConnection.HTTP_OK) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                httpConn.getInputStream()));
        String line = null;
        while ((line = reader.readLine()) != null) {
            response.add(line);
        }
        reader.close();
        httpConn.disconnect();
    } else {
        throw new IOException("Server returned non-OK status: " + status);
    }

    return response;
}

Hier habe ich Fortschrittsbalkenklasse von AndroidHive genommen, aber ich weiß nicht, wie ich es verwenden soll

public class AndroidMultiPartEntity extends MultipartEntity

 {

private final ProgressListener listener;

public AndroidMultiPartEntity(final ProgressListener listener) {
    super();
    this.listener = listener;
}

public AndroidMultiPartEntity(final HttpMultipartMode mode,
        final ProgressListener listener) {
    super(mode);
    this.listener = listener;
}

public AndroidMultiPartEntity(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);
    }
}
}
