Preview Pages in ViewPager

Question

Could you help me? (Preview the next page on screen)

Answer 1

Well ... there is a way to do this. You need to save 2 or 3 elements in memory:

vpPager.setOffscreenPageLimit(3); // or 2

Then configure your viewer as follows:

<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:gravity="center"
    android:layout_width="match_parent"
    android:layout_height="0px"
    android:paddingLeft="24dp"
    android:paddingRight="12dp"
    android:layout_weight="1" />

Then you need to configure these properties of the pager in the containing fragment or activity:

ViewPager vpPager = (ViewPager) view.findViewById(R.id.vpPager);
vpPager.setClipToPadding(false);
vpPager.setPageMargin(12);
// Now setup the adapter as normal

Finally, adjust the width inside the adapter:

class MyPageAdapter : FragmentStatePagerAdapter {
    @Override
    public float getPageWidth (int position) {
        return 0.93f;
    }   

    // ...
}
