Customize dialog which has single-choice list items

Question

I created a Dialog with single-choice list items:

final CharSequence[] items = {\"Red\", \"Green\", \"Blue\"};

AlertDialog.Builder builder = ne         


        

Answer 1

You basically will have to create your own ListAdapter by subclassing one of the available Adapter classes and supply that to the dialog (using builder.setAdapter(...)). If you have an array or list of items/objects, subclassing ArrayAdapter is probably what you'll want to look into.

In your Adapter subclass, you override the getView(...) method (amongst others) and fill the views of your custom layout with data for the supplied position in the list. More specifically, you'll want to set an image against an ImageView and text to a TextView.

A fairly nice tutorial that demonstrates how to implement a custom ArrayAdapter, and happens to be close to what you're trying to accomplish, can be found here. It also shows how to use the ViewHolder/RowWrapper concept.
