how to get a sibling of a clicked view?

Question

I have 2 buttons

I want only one of them to be selected at most at a time.

how can i find a view's sibling while in onClick ?

I have tried:

siblingView = v.getParent().findViewById(R.id.rightBtn);

but parentView has no findViewById method.

is it possible to get an ancestor view (even not direct) ? which is view for sure?

Answer 1

If I understand this correctly, you need some kind of tabs, not two buttons. Check this out for more details about how to implement that kind of behavior, using tabs not buttons.

Answer 2

getParentView return type is an interface ViewParent you can test if it is actually a View (or do not test, if you are sure), and downcast it to View.
