How to get currently visible fragment from activity when using holoeverywhere slider addon?

Question

I want to know how to perform these actions in holoeverywhere:

Get reference to the currently visible and active fragment from the activity when using slider addon in combination with tabber.

Get reference to TabsTabsSwipeFragment from the activity/other fragments and dynamically disable/enable swiping.

Answer 1

Get a reference to the currently visible and active Fragment from the Activity when using slider addon in combination with tabber:

You can provide a tag for a Fragment like this:

sliderMenu.add("tab2", Fragment2.class, SliderMenu.GREEN).setTag("mynavigation-2");

Also you can get the current page number using:

sliderMenu.getCurrentPage();

You have no way of obtaining the current Fragment directly, but you can combine these two methods and find a Fragment via the FragmentManager:

getSupportFragmentManager().findFragmentByTag("mynavigation-" + sliderMenu.getCurrentPage());

Get a reference to the TabsTabsSwipeFragment.java from the Activity/other Fragments and dynamically disable/enable swiping. In your code:

getSupportFragmentManager().findFragmentByTag("mynavigation-2").getChildFragmentManager().findFragmentById(tagFragmentId);

In your Activity:

private int tagFragmentId;
public void setTagFragmentId(int i) {
    Log.i(TAG, "fetched setTagFragmentId: " + i);
    tagFragmentId= i;
}

In your tab Fragment (which is a child of TabsTabsSwipeFragment):

   public void onViewCreated(View view, Bundle savedInstanceState) 
        ((mainActivity) getSupportActivity()).setTagFragmentId(this
                .getId());
    }
