Android Studio base64 image to ListView -

i'm trying listview base64 images. listviews data json-array server , created hashmap.

                    jsonobject c = products.getjsonobject(i);                      // storing each json item in variable                     string id = c.getstring("pid");                     string createdat = c.getstring("created_at");                     string description = c.getstring("description");                     string image = c.getstring("image");                      // creating new hashmap                     hashmap<string, string> map = new hashmap<string, string>();                      // adding each child node hashmap key => value                     map.put("pid", id);                     map.put("description", description);                     map.put("image", image);                     // adding hashlist arraylist                     productslist.add(map);                 } 

and:

   protected void onpostexecute(string file_url) {         // updating ui background thread         runonuithread(new runnable() {             public void run() {                 /*updating parsed json data listview*/                 listadapter adapter = new simpleadapter(                         listactivity.this, productslist,                         r.layout.list_item, new string[] { "product_id",                         "product_description", "product_image" },                         new int[] { r.id.pid, r.id.description, r.id.image });                 // updating listview                 setlistadapter(adapter);             }         });      } 

how can make image string converted imageview? i'm new android studio, don't know if thats smart way that..

above code from: http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/ if helps.

first have convert base64 bitmap, , can set on imageview.

how decode base64 bitmap:

byte[] decodedstring = base64.decode(encodedimage, base64.default); bitmap decodedbyte = bitmapfactory.decodebytearray(decodedstring, 0, decodedstring.length);  

how set bitmap imageview:

imageview mimg = (imageview) findviewbyid(r.id.(your xml img id)); mimg.setimagebitmap(decodedbyte );
