I want a Imageview inside SimpleAdapter?

问题

Could someone point me in the right direction to get a ImageView inside this SimpleAdapter? The TAG_IMAGE should be the Imageview. I am getting this: Type missmatch: Cannot convert from ImageView to int. And yes I am a noob.

protected void onPostExecute(String file_url) {
        // dismiss the dialog after getting all products
        pDialog.dismiss();
        // updating UI from Background Thread
        runOnUiThread(new Runnable() {
            public void run() {
                /**
                 * Updating parsed JSON data into ListView
                 * */
                ListAdapter adapter = new SimpleAdapter(
                        AllProductsActivity.this, productsList,
                        R.layout.list_item, new String[] { TAG_PID,
                                TAG_NAME, TAG_PRICE, TAG_RANDOM, TAG_IMAGE },                               
                        new int[] { R.id.pid, R.id.name, R.id.price,
                                R.id.random, R.id.image });
                // Imageview to show
                // updating listview
                setListAdapter(adapter);
            }
        });

Run the application
