The gallery is using Android's media database to display the list of media. Deleting the file will not be reflected in the database until it scans the filesystem again. That is for example done after rebooting.

You can either delete the file directly through the database or force it to scan the file or folder you just deleted.

File fileToDelete =  new File("filepath");
boolean fileDeleted =  fileToDelete.delete();

// request scan    
Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
scanIntent.setData(Uri.fromFile(fileToDelete));
sendBroadcast(scanIntent);
