[NavigationView] Fix section label alignment

[pubiqq]

Fixes #4178

[leticiarossi]

There's an error with this:"Inconsistent alignment specification between textAlignment and gravity attributes: was center_vertical, expected start"

So we'd need to keep android:gravity="center_vertical|start". However then it's easier to just keep it as is without setting textAlignment since gravity is already working as intended.

What is your reason to use textAlignment instead of gravity?

That's the message from the RtlCompat lint check, isn't it?

I've added an issue, see description.

I see, thank you for filing the issue! the message is from the lint check but it's a blocking error, but I confirmed that keeping both android:gravity="center_vertical|start" and android:textAlignment="viewStart" fixes the issue so we can do that!

Ok, I've rebased the branch with android:gravity="center_vertical|start".

it's a blocking error

It's a false positive. RtlCompat should not be used in the library because it no longer supports API < 17.
