Download Notifications actions

I have an app that in part of this app downloads video files. I show the download in the notification in the status bar. and every notification has a cancel action button. in the first notification cancel action button enable but in another notification cancel action button is disabled!!!

please help me.

my classes:

private void DownloadMovie(String _link, String fileName) { BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(ProductDetails.this); bottomSheetDialog.setContentView(R.layout.dialog_startingdownload); bottomSheetDialog.setCancelable(true); MaterialButton reject_btn = bottomSheetDialog.findViewById(R.id.canceldw_btn); MaterialButton close_btn = bottomSheetDialog.findViewById(R.id.closeWindow); ProgressBar progressBar = bottomSheetDialog.findViewById(R.id.progressbar); TextView downloadingtxt = bottomSheetDialog.findViewById(R.id.txt); TextView progresstext = bottomSheetDialog.findViewById(R.id.progresstxt); TextView TVSizeDownload = bottomSheetDialog.findViewById(R.id.TVSizeDownload); TextView TVSizeTypeDownload = bottomSheetDialog.findViewById(R.id.TVSizeTypeDownload); TextView fileSizetxt = bottomSheetDialog.findViewById(R.id.fileSize); assert TVSizeDownload != null; TVSizeDownload.setVisibility(VISIBLE); assert TVSizeTypeDownload != null; TVSizeTypeDownload.setVisibility(VISIBLE); assert progresstext != null; progresstext.setVisibility(VISIBLE); assert downloadingtxt != null; downloadingtxt.setVisibility(VISIBLE); assert progressBar != null; progressBar.setVisibility(VISIBLE); assert reject_btn != null; reject_btn.setVisibility(VISIBLE); assert fileSizetxt != null; fileSizetxt.setVisibility(VISIBLE); assert close_btn != null; close_btn.setVisibility(VISIBLE); downloadManager = new ThinDownloadManager(1); retryPolicy = new DefaultRetryPolicy(); NewDownloadClass myDownloadStatusListener = new NewDownloadClass(downloadManager, progresstext, downloadingtxt, TVSizeDownload, TVSizeTypeDownload, pathdata, fileName, bottomSheetDialog, progressBar, "film", titleName, ProductDetails.this,lat,lng,product_id,user_id,token,os_ver,deviceName); Toast.makeText(this, "released"+"-"+downloadManager.isReleased(), Toast.LENGTH_SHORT).show(); myDownloadStatusListener.delegate = this; isDownloadCompleted = false; Uri downloadUri = Uri.parse(_link); Uri destinationUri = Uri.parse(pathdata + fileName); retryPolicy = new DefaultRetryPolicy(5000, 3, 2f); downloadingtxt.setText("downloading"); DownloadRequest downloadRequest = new DownloadRequest(downloadUri) .setRetryPolicy(retryPolicy) .setDestinationURI(destinationUri).setPriority(DownloadRequest.Priority.HIGH) .setDownloadContext("first")//Optional .setDeleteDestinationFileOnFailure(true) .setDownloadResumable(true) .setStatusListener(myDownloadStatusListener); if (downloadManager.query(downloadId) == DownloadManager.STATUS_NOT_FOUND) { downloadId = downloadManager.add(downloadRequest); } close_btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { bottomSheetDialog.dismiss(); } }); reject_btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { bottomSheetDialog.dismiss(); downloadManager.cancelAll(); if (new File(pathdata + fileName).exists()) if (new File(pathdata + fileName).delete()) { Log.e("DEL FILE FROM SD", "--ok"); } if (notificationId != 0) if (mNotifyManager != null) mNotifyManager.cancel(notificationId); isDownloadCompleted=true; } }); bottomSheetDialog.show(); }
