Android ProgressBar in ListView while using DownloadManager

Question

I have a ListView in which each item represents a PDF file. When the user clicks on an item, the application must download the file on external storage. Now the download doe

Ok so I managed to do what I wanted to do with a HashTable :

// HashTable to store download id's and loaders
Hashtable storeTable = new Hashtable();

In my onClickListener method, after loader[z] and lastDownload[ld] take their value, I put them in the HashTable : ( the downloa id will be the key, the loader will be the value )

// Storing download id and loader in HashTable
storeTable.put(lastDownload[ld], loader[z]);

In my Broadcast Receiver's onReceive method, instead of doing this :

if(lastDownload[y] == referenceId)

I look if the HashTable contains the download id of the intent :

if(storeTable.containsKey(referenceId))

And I put the correct value in the loader :

loader[y] = storeTable.get(referenceId);

Then I just have to put the loader's visibility to GONE where I want. This solution works for me, but I will update it if I find something new.

Here is my new code :

In the onClickListener method : ( not complete here )

// Loader of the clicked item is made visible
loader[z].setVisibility(View.VISIBLE);

// Construction of the URL
SharedPreferences codeSaveUrl = getSharedPreferences(PREFS_TEXT,Context.MODE_PRIVATE);
url2 = codeSaveUrl.getString("defaut", ""); // Organization code
uri = url10 + url2 + "&file=" + udl ;

// URL parse to URI
Uri myuri = Uri.parse(uri);

// Enqueue file to downloads, with notification. Storage of download id in a table
lastDownload[ld] = mgr.enqueue(new DownloadManager.Request(myuri)
.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI |DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false)
.setTitle(udl + ".pdf")
.setDescription("Téléchargement en cours")
.setDestinationInExternalPublicDir("/Protocols/", (udl+".pdf"))
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE));

// Storing download id and loader in HashTable
storeTable.put(lastDownload[ld], loader[z]);

// Increment variables for next downloads
ld=ld+1;
z=z+1;

Broadcast Receiver :

// Broadcast Receiver called when a download is finished
BroadcastReceiver onComplete = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        // referenceId is the download's id for which the method is called
        long referenceId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
        // If y (=0 at the beginning) is inferior to the number of downloads
        if(y
