Adicionar layout a uma página de ScreenSlide Utilizando XML

Olá.

No meu app, tenho três layouts, cada uma correspondendo a uma página.
Utilizo o ScreenSlide para a passagem de página. Antes, para cada página,
havia uma imagem, fazia:

int mPaginas [] = { R.drawable.pag1, R.drawable.pag2. R.drawable.pag3 };

E chamando estas imagens, dentro do meu código, funcionava perfeitamente.
Mas me limita à outras coisas que quero que faça. Por isso, quero recorrer
aos XMLs, ao invés de chamar as imagens. Como faço isso?

Seguem os códigos:

import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.util.Log;
import android.view.ViewGroup;
import android.widget.LinearLayout;

public class RelatorioActivity extends Activity
{
    private int mPaginas[] = { R.layout.fragment_1_pagina, R.layout.fragment_2_pagina, R.layout.fragment_3_pagina };

    @Override
    public void onCreate(Bundle savedInstance)
    {
        super.onCreate(savedInstance);
        setContentView(R.layout.activity_relatorio);

        ViewPager vp = new ViewPager(this);
        LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        vp.setLayoutParams(lp);

        vp.setAdapter(new AdapterPaginas(this, mPaginas));

        vp.setOnPageChangeListener(new ViewPager.OnPageChangeListener()
        {
            @Override
            public void onPageSelected(int arg0)
            {
                Log.i("Script", "onPageSelected()");
            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2)
            {
                Log.i("Script", "onPageScrolled()");
            }

            @Override
            public void onPageScrollStateChanged(int arg0)
            {
                Log.i("Script", "onPageScrollStateChanged()");
            }
        });

        LinearLayout ll = (LinearLayout) findViewById(R.id.LinearLayout1);
        ll.addView(vp);
        }
    }
}

</RelativeLayout>

Imagino que eu precise criar uma variável de referência à um objeto
Pagina1Fragment no onCreate da RelatorioActivity;

algo como:

Pagina1Fragment p1F = new Pagina1Fragment();

// ... outros códigos

p1F.onCreateView( "O que colocar aqui" );

Na linha:

p1F.onCreateView( * );

* O que eu devo colocar, caso seja esta a resolução?
