Setting ListView Image Dynamically

Question

I'm trying to set a Image on the ListView and I've written the adapter code and it seems to work fine, but the line of the to actually get the image is always giving an error about not being able to find an image.

The code to get the image is as follows,

Bitmap logo = BitmapFactory.decodeResource(MainActivity.this.getResources(), R.drawable.dm);

// creating new HashMap
HashMap<String, Object> map = new HashMap<String, Object>();

// adding each child node to HashMap key => value
map.put(TAG_BODY, id);
map.put(TAG_TITLE, name);
map.put(TAG_URL, uri);
map.put(TAG_TIME, dateFormated);
map.put(TAG_SITE, logo);

// adding HashList to ArrayList
productsList.add(map);

The code that then applies to ListView is

ListAdapter adapter;
adapter = new SimpleAdapter(
MainActivity.this, productsList,
R.layout.list_row, new String[] { TAG_BODY, TAG_TITLE, TAG_URL, TAG_TIME, TAG_SITE},
  new int[] { R.id.id, R.id.headline, R.id.url, R.id.time, R.id.list_i});

// updating listview
setListAdapter(adapter);

and the error is

you can see here android.widget.SimpleAdapter SimpleAdapter's setViewImage method accept only two parameters :

First Param : ImageView id in which you want to set current image

Second Param : String (if you want to set ImageView src from file path) or Integer( if you want to set ImageView src from drawable's id)

so you will need to pass only drawable id instead of Bitmap of drawable

Ok, but how do you actually go about doing that. e.g. the SimpleAdapter call

@JamesKraw : because you are storing Object in HashMap instead of String or Integer

Yeah figured it out thanks. Was as simply as changing the map.put(TAG_SITE, logo); to map.put(TAG_SITE, R.drawable.logo); and removing all the BitMap stuff. :)
