How to know if a Fragment is Visible?

Question

I\'m using the support library v4 and my questions are, How to know if a Fragment is Visible? and How can I change the propierties of the Layout inflated in the Fragment? Th

One thing to be aware of, is that isVisible() returns the visible state of the current fragment. There is a problem in the support library, where if you have nested fragments, and you hide the parent fragment (and therefore all the children), the child still says it is visible.

isVisible() is final, so can't override unfortunately. My workaround was to create a BaseFragment class that all my fragments extend, and then create a method like so:

public boolean getIsVisible()
{
    if (getParentFragment() != null && getParentFragment() instanceof BaseFragment)
    {
        return isVisible() && ((BaseFragment) getParentFragment()).getIsVisible();
    }
    else
    {
        return isVisible();
    }
}

I do isVisible() && ((BaseFragment) getParentFragment()).getIsVisible(); because we want to return false if any of the parent fragments are hidden.

This seems to do the trick for me.
