how to take the value form edittext in a listview?
===

I have a custom list with one textView and one 
    edit text in each row. My question is: whenever user enters 
    any number inside the edittext,at that time i want to take the 
    value from the edittext and add it with the previous value and
     displayed in the top textview.
        For eg. Say inside number of edittext i entered 10 in any 
    edittext. 10is the first number entered.then it is going to add
     with 0.after that if he enter 15 in another edittext,then 10+15 = **25**
     should be displayed in the top textview.
