알림 영역에 진행률 표시 줄을 표시하는 방법은 무엇입니까?

Question

안녕하세요, iam이 PHP 서버에 동영상을 업로드하는 안드로이드 응용 프로그램을 만들고 있습니다.
업로드를 수행하려면 HTTPURLConnection을 사용하십시오. Iam은 알림 영역에 진행률 표시 줄을 표시하고 업데이트하는 데 큰 충격을 받았습니다. 이걸 그리고는 누군가가 알고있는 경우 hint.Please 내게 도움을받을 수 없다 할 거의 일주일에 검색

내 코드 :

HttpURLConnection conn = null; 
     DataOutputStream dos = null; 
     DataInputStream inStream = null; 
     String lineEnd = "\r\n"; 
     String twoHyphens = "--"; 
     String boundary = "*****"; 
     int bytesRead; 
     byte[] buffer; 
     String urlString = "http://xxxxx/My_path.php"; 
     try { 
      long total = 0; 
      int count = 0; 
      // ------------------ CLIENT REQUEST 
      UUID uniqueKey = UUID.randomUUID(); 
      fname = uniqueKey.toString(); 
      Log.e("UNIQUE NAME", fname); 
      FileInputStream fileInputStream = new FileInputStream(
        new File(selectedPath)); 
      URL url = new URL(urlString);      
      conn = (HttpURLConnection) url.openConnection(); 
      int length=selectedPath.length(); 
      conn.setDoInput(true); 
      conn.setDoOutput(true); 
      conn.setUseCaches(false); 
      conn.setRequestMethod("POST"); 
      conn.setRequestProperty("Connection", "Keep-Alive"); 
      conn.setRequestProperty("Content-Type", 
        "multipart/form-data;boundary=" + boundary); 
      dos = new DataOutputStream(conn.getOutputStream()); 
      dos.writeBytes(twoHyphens + boundary + lineEnd); 
      dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" 
        + fname + "" + lineEnd); 
      dos.writeBytes(lineEnd); 
      buffer = new byte[8192]; 
      bytesRead = 0; 
      while ((bytesRead = fileInputStream.read(buffer)) > 0) {         
       dos.write(buffer, 0, bytesRead);      
      }   
      dos.writeBytes(lineEnd); 
      dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);   
      Log.e("Debug", "File is written"); 
      fileInputStream.close(); 
      dos.flush(); 
      dos.close(); 

     } catch (MalformedURLException ex) { 
      Log.e("Debug", "error: " + ex.getMessage(), ex); 
     } catch (IOException ioe) { 
      Log.e("Debug", "error: " + ioe.getMessage(), ioe);

     // ------------------ read the SERVER RESPONSE 
     try {

      String str; 
      while ((str = inStream.readLine()) != null) {

긴 검색 후 알림 영역에 진행률 표시 줄을 표시하는 작업을 마쳤습니다. 우리가 필요로하는 것은 asynctask입니다. 여기에 표시된 코드가 완벽하게 작동하지 않을 수 있습니다. iam 테스트가 제대로 작동합니다. 확인하고 upvote하십시오 이 대답은 효과가 있다면.

RemoveView에서, 당신은 진행 표시 줄을 업데이트 할 수 있습니다. 그래서 예제 코드의 일부를 결합,이 같은 것을 얻을 :

public class MyActivity extends Activity { 
private static final int PROGRESS = 0x1; 
private static final int MAX_PROGRESS = 100; 

private int mProgressStatus = 0; 

private Handler mHandler = new Handler(); 

protected void onCreate(Bundle icicle) { 
    super.onCreate(icicle); 

    //define Notification 
    //... 

    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification_layout); 
    contentView.setProgressBar(R.id.progress_bar, MAX_PROGRESS, mProgressStatus, false); 
    notification.contentView = contentView; 

    // Start file upload in a background thread 
    new Thread(new Runnable() { 
     public void run() { 
      while (mProgressStatus < MAX_PROGRESS) { 
       mProgressStatus = doWork(); 

       // Update the progress bar 
       mHandler.post(new Runnable() { 
        public void run() { 
         contentView.setProgressBar(R.id.progress_bar, MAX_PROGRESS, mProgressStatus, false); 
        } 
       }); 
      } 
     } 
    }).start(); 
    } 
}
