can i swipe pages of viewpager in reverse order?

Answer 1

Try this,

and this will make user swipe right to left

Answer 2

At the time of this post, ViewPager still doesn't handle RTL correctly. Here's a a workaround when using TabLayout:

1. Set android:layoutDirection="ltr" in the TabLaout XML, so it will always display left-to-right.

2. Before you call setupWithViewPager(viewPager), check if running in RTL, and if so, reverse the order of the tabs, and start with the last tab:

   if (MyApp.isRTL()) {
       Collections.reverse(pgAdapter.fragmentList);
       viewPager.setCurrentItem(pgAdapter.getCount() - 1);
   }
   

RTL can be checked using the following code:

public static boolean isRTL() {
    final int directionality = Character.getDirectionality(
            Locale.getDefault().getDisplayName().charAt(0));
    return directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT ||
            directionality == Character.DIRECTIONALITY_RIGHT_TO_LEFT_ARABIC;
}
