How To Display Two Fragments At The Same Time Using Tablayout?

I use Android Tab Example with two tabs, view pager and fragments (structure on the image): For get fragments i use the solution from this post. When my device is rotation i want

Solution 1:

In activity_main.xml

<FrameLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="match_parent"android:paddingBottom="16dp"android:paddingLeft="16dp"android:paddingRight="16dp"android:paddingTop="16dp"
    ><FrameLayoutandroid:id="@+id/main_content"android:layout_width="match_parent"android:layout_height="match_parent"
    ></FrameLayout></FrameLayout>

In MainActivity.java

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.annotation.NonNull;

publicclassMainActivityextendsAppCompatActivity {

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        replaceFragment(0);

  }

       publicvoidreplaceFragment(int position) {
        Fragmentfragment=null;
        switch (position) {

            case0:
                fragment = newTabOneFragment();
                break;
            case1:
                fragment = newTabTwoFragment();
                break;
            default:
                break;
        }

        if (null != fragment) {

            FragmentManagerfragmentManager= MainActivity.this.getSupportFragmentManager();
            FragmentTransactiontransaction= fragmentManager.beginTransaction();
            transaction.replace(R.id.main_content, fragment);
            transaction.addToBackStack(null);
            transaction.commit();

        }
    }

}

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;

publicclassTabOneFragmentextendsFragment {

    }

    @Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        this.inflatedView = inflater.inflate(R.layout.fragment_tab_one, container, false);

  }
}

        super.onCreate(savedInstanceState);
    }

    @Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        this.inflatedView = inflater.inflate(R.layout.fragment_tab_two, container, false);
