Tabhost with pager view, ClassCast error

I have an activity that populates a scroll view for each day of the week and displays them with tabs made in the action bar using the view pager. Whenever I go back to a tab that I have already visited, I get an error when the class is passed. This is my cat. Can someone please tell me why this exception is being thrown.

I had a similar problem. While looking for answers, I came across this post. Unusual ClassCastException in android.widget.ProgressBar.onRestoreInstanceState

In all our cases, android.view.AbsSavedState $ 1 was added to another component.

The accepted answer says the problem is that the app is reusing IDs.



"Make sure your application doesn't reuse the same identifier in two different places."

If you are using eclipse the Lint tool can help you find duplicate id. enter image description here... Hope this helps.
