android programming spinner swap

Question

Programming

you need to make it so that when you click on a certain button (an application of the translator type, and a button with arrows) one of the selected elements of the spinner itam changes to another, well, they change places, so how can this be implemented?
Here is the code but it doesn't work!

int spinner1Index = spinner.getSelectedItemPosition();
        spinner.setSelection(spinner2.getSelectedItemPosition());
        
        spinner2.setSelection(spinnerfirst);

can you suggest something similar or fix it!
