<android.support.v4.view.ViewPager
    android:id="@+id/panelPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
</LinearLayout>

MyPagerAdapter.java

public class MyPagerAdapter extends PagerAdapter {

@Override
public int getCount() {
    return 2;
}

@Override
public Object instantiateItem(final View collection, final int position) {

    LayoutInflater inflater =
            (LayoutInflater) collection.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    int resId …
