Using the gallery to scroll between views

Question

I follow the Android Gallery guide ( http://developer.android.com/guide/tutorials/views/hello-gallery.html ), but instead of simple images, I would like to be able to move horizontally to a new new screen, such as LinearLayout. An idea is a kind of tabulation behavior, but the user can scroll through the screens.

I created a gallery, created a GalleryAdapter, which extends from the BaseAdapter and the getItem () method. I am trying to return a complex view:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    /*ImageView i = new ImageView(this.c);
    i.setImageResource(R.drawable.login);
    i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    i.setScaleType(ImageView.ScaleType.FIT_XY);
    return i;*/     

    ScrollView view = (ScrollView)this.c.getResources().getLayout(R.layout.main);
    return view;
}

In the above example, it will work if I use ImageView, but it fails if I use a more complex view like scrollView loaded from resources.

Any idea why? The exception is:
