how to create Rtl ViewPager for locale?

Question

How to create Rtl ViewPager with both En and Arabic locale?

I am using this code :

https://github.com/diego-gomez-olvera/RtlViewPager

but i cannot implement both locale.

Answer 1

Look at this line in RtlViewPager's source. It controls whether the RtlViewPager is in right-to-left mode.

If you extend RtlViewPager and override this method to always return true, the English locale should also appear as RTL.

For example:

public class AlwaysRtlViewPager extends RtlViewPager {
    public AlwaysRtlViewPager(Context context) {
        super(context);
    }

    public AlwaysRtlViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected boolean isRtl() {
        return true;
    }
}

Just replace your usages of RtlViewPager with this sub-class and you should get the desired result.

Answer 2

You don't need any third party library. Android jetpack recently added new UI component called ViewPager2 which supports RTL Layout.

The below answer talks about Migration guide and sample github app to support RTL view pager.
