Refreshing data

Hi. First of all I want to say that I'm new to mobile dev and it's my first android app.

I have an activity that has a textview with some data from sqlite db. It launches another activivity that modifies this data in db and finishes the activity. When I come back to the main I still have old data in textview. How to refresh it?

This is just one example of an item that needs refreshing after db operations. There are other items like lists etc.

Thanks for your help!
