Solution 1:

According to documentation, you should call setProgressNumberFormat (null) on your ProgressDialog instance to get this behavior

Hey Here Downloading a file from a server, saving a file to the sdcard and showing a progress bar.

publicclassXYZextendsActivity {

    publicstaticfinalintDIALOG_DOWNLOAD_PROGRESS=0;
    private Button startBtn;
    private ProgressDialog mProgressDialog;

    /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        startBtn = (Button)findViewById(R.id.startBtn);
        startBtn.setOnClickListener(newOnClickListener(){
            publicvoidonClick(View v) {
                startDownload();
            }
        });
    }

    privatevoidstartDownload() {
        Stringurl="http://.jpg";
        newDownloadFileAsync().execute(url);
    }
    @Overrideprotected Dialog onCreateDialog(int id) {
        switch (id) {
        case DIALOG_DOWNLOAD_PROGRESS:
            mProgressDialog = newProgressDialog(this);
            mProgressDialog.setMessage("Downloading file..");
            mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            mProgressDialog.setCancelable(false);
            mProgressDialog.show();
            return mProgressDialog;
        default:
            returnnull;
        }
    }

classDownloadFileAsyncextendsAsyncTask<String, String, String> {

    @OverrideprotectedvoidonPreExecute() {
        super.onPreExecute();
        showDialog(DIALOG_DOWNLOAD_PROGRESS);
    }

    @Overrideprotected String doInBackground(String... aurl) {
        int count;

    try {

    URLurl=newURL(aurl[0]);
    URLConnectionconexion= url.openConnection();
    conexion.connect();

    intlenghtOfFile= conexion.getContentLength();
    Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);

    InputStreaminput=newBufferedInputStream(url.openStream());
    OutputStreamoutput=newFileOutputStream("/sdcard/some_photo_from_gdansk_poland.jpg");

    byte data[] = newbyte[1024];

    longtotal=0;

        while ((count = input.read(data)) != -1) {
            total += count;
            publishProgress(""+(int)((total*100)/lenghtOfFile));
            output.write(data, 0, count);
        }

        output.flush();
        output.close();
        input.close();
    } catch (Exception e) {}
    returnnull;

    }
    protectedvoidonProgressUpdate(String... progress) {
         Log.d("ANDRO_ASYNC",progress[0]);
         mProgressDialog.setProgress(Integer.parseInt(progress[0]));
    }

    @OverrideprotectedvoidonPostExecute(String unused) {
        dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
    }
}
}

Please visit this link.

Also It's explained in full in ApiDemos inside the SDK. The example that you want is named: ProgressBar3.java and can be found in \ApiDemos\src\com\example\android\apis\view\

Also, if you want to remove the borders of the dialog so that only the progress bar appears you can define the dialog itself as a transparent view/overlay (it's explained in the examples as well).
