Provided you have a resource named showFactsButton in one of your Layout XML files, you can get its view and assign it to a variable like:

Button myButton = (Button) findViewById (R.id.showFactButton);

You can then setup up some code to respond to a click of that button with something like:

myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                // call your function here
            }
        });

Hope that helps.
