I don't know how to fix this because when i ran my emulator.. my layout runs ok.. i just can't edit it easily i have to hard code it... Any inputs would be helpful on how to fix this or does anyone of you have fixes on this issue my guess is that its on the adt plugin..

By the way im using Juno Eclipse and ADT latest version

You will also get the ClassCastException if you have multiple scrolling views on one screen. For example, if you have a ListView inside a ScrollView, you will see this exception. Luckily, Eclipse underlines the problem and displays this:

The vertically scrolling ScrollView should not contain another vertically scrolling widget (ListView)

when you hover over it.

this is a known issue with custom layouts.

The visual layout editor only loads classes that it reads from the XML. Basically when it finds a node in the XML that isn't a default widget it asks eclipse to load the corresponding class. It is possible that the custom class loader we did doesn't actually handle the case where the loaded class requires loading another class from the project.

Here's a similar problem

here's a solution, haven't tried it myself though..
