Android Question Searchview clearing the selected value

HI All, I am finding that once I have used the selection and passed the values to another Activity ( After the other activity the workflow goes back to the main activity) , The selected value appears the next time I go back into that Activity. Is there anyway of clearing that , and when should I clear it.

I put message boxes all over to see where the flow goes and it comes back to Activity Resume, If I use the back key and use SearchView again , it goes back to Activity Create and then it is cleared.

Any ideas would be useful. Thank you
