android - Universal-Image-Loader Custom FileNameGenerator based on local file name -

I am using a Universal Image Loader to display images downloaded from the URI or the first in the disk cache implementation Available from.

I want to display the music album cover, but there can be only one URI for the cover in more than one track (i.e. track from the same album). I want that even if the image is the same, each time it is stored for each track with the name of the track, because I want the users to be able to change the default armor with a custom one, even so That's for each single track.

For example

• 01 - Track 01.M.E
• 02 - Track 02.mpi

The same album and cover is from the URI http: //something/img.jpg , I have to be on the disk cache

• 01 - Track 01.jpg
• 02 - Track 02.jpg

Even if it is the same image.

So I have coded a filename generator that stores set for hash for each URI , where The full path of the hash file is SHA-1.

Here's my implementation:

  Public MyFileNameGenerator {string} {super}; This.ext = ext } Hashmap & lt; String, hashaseet & lt; String & gt; & Gt; Name = new hashmop & lt; String, hashaseet & lt; String & gt; & Gt; (); @ Override public string generated (string image ury) {if (imageUri == empty) return tap; If (imageUri.startsWith ("file: ///")) {back filename utility. Extension (URI.parse (imageUri) .getLastPathSegment ()) + "." + Ext. How To Identify The Right Hash? // Return filename utility. Revue Extension (Data.Current.get (names.get (imageUri)). GetName ()) + "." + Ext. } Public Zero Settrackdata (String Yuri, String Hash) {If (Kontsky (Yuri's Name) names! Input (Yuri, new hashset & lt; string & gt; ()); Names.get (URI) .add (hash); }  

But I am at a dead end, because it is impossible to understand what image I am displaying, because only the image moves in the form of parameters and more ish Relationship can be the same urine

How can I stop this issue?

I think I have found a solution for this.

Whenever I call my ImageLoader to show an image for example, I use

  (if! = Tap & amp;! Uri.isEmpty ()) {Uuri = Uri.parse (URI) .buildUpon () .appendQueryParameter ("myhashkeyparameter", "myHashValue"). ToString (); } MImageLoader.displayImage (uri, mImageView);  

This code will add a vaild uri query parameter, Yuri will be created:

  http: //someuri/image.jpg? MyHashkeyPerameter = MyHashValue  

Then in the generated method of FileNameGenerator I

  string hash = URI. Parse (imageUri) .getQueryParameter ("myhashkeyparameter");  

To recover the image as a key without the use of Yuri

Full code:

  @ Override generated public string (string image Yuri) {if (imageUri == faucet} imageUri.isEmpty ()) Return ""; If (imageUri.startsWith ("file: ///")) {back filename utility. Extension (URI.parse (imageUri) .getLastPathSegment ()) + "." + Ext. } String hash = uri. PRSE (Image Yuri). Dataparmetra ("MyHoashquimeter"); If (null == hash} hash.ISPT ()) "" return; If (Data.currentFiles.containsKey (hash)) {return file name utility .removeExtension (Data.currentFiles.get (hash) .getName ()) + ".png"; } And return ""; }  

All you have to be careful is that the string not already used in the query URL, hence avoid conventional names like name, hash, h, title etc.
