Best way to unfocus edittext when user interacts with another (non-texual) input element

I have an activity with some edittexts and some checkboxes, etc.

I have validators set on text entries that get executed when a text entry loses focus. But the problem is when the user clicks/touches a checkbox, edittext doesn't lose focus and therefore the validator is not run.

What is the best way for causing unfocus of text entries when the user touches another input field? I know I can e.g. set a handler on every checkbox to force unfocusing of text fields happen, but I think there is probably a more concise/general method for this purpose; Setting a handler on every checkbox seems too cumbersome and error prone.

thank u.
