Manage listview and sqlite instance

I come with a small problem in my application, I use android studio for development, what happens is that I have 3 activities:

• In SELECT I choose an option by means of a spinner and by checkbox , I generate a query that I keep it in a variable type String.

• In the List activity, a Listview

is generated

• In Knowledgebase the entire database of the application is saved

The problem that I have (and I know it is very simple but I still do not know how to do it and has given me a problem for a long time) is that when I generate my query in EleccionSe, how can I send it to the List activity, necessarily as I'm doing it, the phrase has to reach List and then it sends the query to the database.

How could I send that query? I thank you infinitely who can help me: D

Here are the parts of my activities:
