custom listview empty edittext and checkbox

I have a custom array adapter which has a imageview, 2 textviews an edittext and a checkbox. I need to get the text from my textviews and my edittext then send that data to another activitya textview when the checkbox is checked.

How can I set up a method to check if the edittext is empty as I need the checkbox only to trigger when there is a value in the edittext.

How can I get the data sent through to another activity.

Thanks
