getSupportFragmentManager() is only defined for the class FragmentActivity, not for Context. Thus, the compiler can't resolve the call if you try to call it on an object of type Context.

You can use reflection to do this in a safe way. This will always work as long as you pass your FragmentActivity as the Context. Note: FragmentActivity is a subclass of Context, and thus you can pass FragmentActivity wherever you can pass Context.

So use this code instead:

if (getContext() instanceof FragmentActivity) {
    // We can get the fragment manager
    FragmentActivity activity = (FragmentActivity(getContext()));
    FragmentTransaction t = activity.getSupportFragmentManager().beginTransaction();
}
