How to use tabs with items within a same xml without using fragments?

Navigation
1

I have an Activity where I will only need 2 tabs , one that will open right away telling a story using simple textview, and another about team members using gridview.

I did not want to use fragments in this case, so I thought about putting the tabs at the top, and the layouts below where I could switch using visibility VISIBLE and GONE

I thought of something onclicklistner tab style, but I do not know how to do this with tabs, and the examples I find on google does not show a solution to this.

I also thought about using tabhost, but I do not understand how it works, because when I put it in my xml it does not appear when I run the app.

Can anyone help me with this solution if at all possible?

If you have a way to get the tab id to click it would help me a lot.

The structure I made is this:

AndtheXMLlookslikethis:

<android.support.constraint.ConstraintLayoutxmlns:android="http://schemas.android.com/apk/res/android"

I solved it this way and it worked: 

final ConstraintLayout clhistoria = (ConstraintLayout) view.findViewById(R.id.cl_sobre_historia);
    final GridView gvequipe = (GridView) view.findViewById(R.id.gv_sobre_equipe);

    TabLayout tabsobreitens = (TabLayout) view.findViewById(R.id.tabsobrepagesitens);
    tabsobreitens.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            switch(tab.getPosition()) {
                case 0:
                    clhistoria.setVisibility(View.VISIBLE);
                    gvequipe.setVisibility(View.GONE);
                break;
                case 1:
                    clhistoria.setVisibility(View.GONE);
                    gvequipe.setVisibility(View.VISIBLE);
                    break;
            }
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) { }

        @Override
        public void onTabReselected(TabLayout.Tab tab) { }
    });

Even though someone knows other ways and can share, I thank them.
