SlidingTabLayout: replace with fragment

Question

I've the following situation:

• Linear Layout
  
  • ToolBar
  • SlidingTabLayout
  • ViewPager
  • FrameLayout

Initially, I only add a fragment to the FrameLayout, and all works. Next I remove this fragment, create new Adapter, and bind adapter to the SlidingTabLayout. All works again, but now I need to set tab visibility to false, and I do this with

slidingTabLayout.setVisibility(View.GONE);

but I also need to replace the current view with a new fragment. Usually I do this with:

getFragmentManager().replace(parent, newFragment);

but now I can't do this because getFragmentManager().replace(ViewPager, newFragment); doesn't works. So how can I do this? And if is possible, can I add the ViewPager replacing in the backstack?

Answer 1

I find a solution. I made the following update to my layout:

• Linear Layout
  • ToolBar
  • Linear Layout (id: parentScroll)
    1. SlidingTabLayout
    2. ViewPager
  • Frame Layout (id: parent)

So when I need to hide all the tabs and the ViewPager, in order to inflate a new Fragment in the Frame Layout, I do the following:

 parentScroll.setVisibility(View.GONE);
 MyFragment myFragment= new MyFragment ();
 FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
 transaction.add(R.id.parent, myFragment, "MYTAG");
 transaction.commit();

In the onBackPressed of this new fragment:

 MyFragment myFragment= (MyFragment) getSupportFragmentManager.findFragmentByTag("MYTAG");
 if (myFragment!= null && myFragment.isVisible()) {
     parentScroll.setVisibility(View.VISIBLE);
     getSupportFragmentManager().beginTransaction().remove(myFragment).commit();
 }
