Call method which needs parameters using android:onClick in XML

I have a Button and it is defined in XML. I am using android:onClick to call a method called showMessage. Simple method example:

    public void showMessage(View v){
    Log.w(TAG, "Hi");
    }

Now suppose my method needs for example a boolean and an int as parameters, how to do something like:

android:onClick="showMessage(boolean isExpensive, int money)"
