While iterating display images

Hello Ben!!

Now situation is i have ArrayList, and with Iterator loop want to show images in my layout. Can it be possible in TextView. Please Suggest.

Code preview [code] Iterator<Product> it = products.iterator(); ImageView myImage = (ImageView) findViewById(R.id.imageView2); while(it.hasNext()) {

        Product currProduct  = it.next();
        String image = currProduct.image;

        myImage.setImageDrawable(getResources().getDrawable(image));
                    // Not working


        content = content + "\n\n\nName :" +  currProduct.name + "\n";
        content = content + "Position :" +  currProduct.position + "\n";
    }

[/code] Thanks!!

I had a lengthy discussion about this a while back with another student. Unfortunately Android doesn't include any default adapters for ListViews that display images. You need to build a custom adapter. It's easier than it sounds, though it's a little confusing without a good example. We will definitely cover it before too long.

Check out that forum post and see if it has any helpful information. I have to step away but wanted to give you a quick answer in case you start working on this soon. Let me know if you have any follow-up questions.

Hello Ben!!

Just followed your Custom Adapter code. and code is as follows :

private void parseXML(XmlPullParser parser) throws XmlPullParserException,IOException
    {
        ArrayList<CustomObject> items = null;
        int eventType = parser.getEventType();
        CustomObject currentProduct = null;
        while (eventType != XmlPullParser.END_DOCUMENT){
            String name = null;
            switch (eventType){
                case XmlPullParser.START_DOCUMENT:
                    items = new ArrayList<CustomObject>();
                    break;
                case XmlPullParser.START_TAG:
                    name = parser.getName();
                    if (name.equals("member")){
                        currentProduct = new CustomObject();
                    } else if (currentProduct != null){
                        if (name.equals("name")){
                            currentProduct.name = parser.nextText();
                        } else if (name.equals("position")){
                            currentProduct.position = parser.nextText();
                        } else if (name.equals("image")){
                            currentProduct.image= parser.nextText();
                        }
                    }
                    Log.i(TAG, "Node parsing");
                    break;
                case XmlPullParser.END_TAG:
                    name = parser.getName();
                    if (name.equalsIgnoreCase("member") && currentProduct != null){
                        items.add(currentProduct);
                    }
            }
            eventType = parser.next();
        }

        CustomAdapter adapter = new CustomAdapter(DepartmentActivity.this, items);  // Error Here
//Intellisense suggests to change type of 'items' to 'ArrayList<CustomObject>'

        setListAdapter(adapter);

      //  printProducts(items);
        Log.i(TAG, "XML parsed " + items.size());
    }

i believe its already. Please guide from here. I am stucked. If u another souce code copy (Can forward u?)

Thanks :) u Rox
