Fix: Snackbar overlapping bottom navigation bar on Explore screen

[Shoaibkhalid65]

Fixes #6741

Problem

On the Explore screen, when an error occurs while loading images, the Snackbar was appearing at the very bottom of the screen and overlapping the bottom navigation bar, making it partially hidden.

Root Cause

showShortSnackbar in ViewUtil had no anchor view parameter, causing the Snackbar to render at the bottom of the window, covering the navigation bar.

Fix

• Added optional anchorView parameter to ViewUtil.showShortSnackbar()
• In BasePagingFragment.showSnackbar(), passed R.id.fragment_main_nav_tab_layout as the anchor view so the Snackbar appears above the bottom navigation bar

After:

Tested on: Samsung a07 | Android 16

Thanks a lot for contributing @Shoaibkhalid65. No issues with the current approach, but how about using Coordinator layout at the xml file i.e in main.xml?

[Shoaibkhalid65]

Hi @neeldoshii, I tried your suggestion of using CoordinatorLayout. I first tried replacing the RelativeLayout in main.xml but it caused all fragment content to shift behind the bottom navigation bar and the Snackbar stopped showing entirely. I also tried replacing the RelativeLayout in fragment_explore_map.xml but the TabLayout started overlapping the content below it.
I think the issue is that the existing layouts rely on RelativeLayout's layout_above and layout_below constraints for positioning, and switching to CoordinatorLayout without restructuring the full layout hierarchy breaks those constraints.
Could you point me to the exact file or layout you had in mind? I want to make sure I implement this the right way rather than guessing. Happy to make whatever changes you suggest.
