Fix part of #5607: Prevent toolbar title truncation in AudioLanguageFragment at 200% font scaling

[anmoltrvd01]

Explanation

Fix part of #5607 (PR 11: Settings & Help)

This PR addresses a UI issue in AudioLanguageFragment where the toolbar title was truncated when the system font size was increased to 200% (Android 14+).

Changes made:

• Introduced a custom TextView inside the Toolbar layout.
• Enabled marquee scrolling for the toolbar title to ensure the full text remains accessible..
• Configured the title to be focusable and selected programmatically to trigger marquee behavior.
• Ensured compatibility with large font sizes and display scaling settings.

Testing performed:

• Enabled 200% font scaling on an Android 14 emulator.
• Tested with maximum Display Size setting.
• Verified that the full toolbar title is visible without truncation.
• Tested in both portrait and landscape modes to ensure there is no overlap, clipping, or layout breakage.

Tested all fragments in PR 11: Settings & Help with font scaling set to 200% on an Android 14 emulator.

Results:

• AppLanguageFragment – no truncation observed
• AudioLanguageFragment – toolbar title was truncated → fixed using a marquee TextView
• ReadingTextSizeFragment – no truncation observed
• HelpFragment – no truncation observed
• FAQListFragment – no truncation observed

Only AudioLanguageFragment required a fix.

Screenshots (before/after) are attached below:

Before: Toolbar title truncated at 200% font scaling.

After: Marquee effect scrolls the title instead of truncating (see attached recording).

(Enabled 200% font scaling & Tested with maximum Display Size setting.)

Screen.Recording.2026-03-07.160639.mp4

The recording shows navigation through each screen confirming that only AudioLanguageFragment required a fix.

Hi @adhiamboperes, it looks like the comment coverage workflow requires manual approval for first-time contributors, so the coverage checks are currently failing. Could you please approve and re-run the workflow when you have time?
Thank you!

[adhiamboperes]

@anmoltrvd01, apologies for the delayed review.

I have left a suggestion for how to test the changes, otherwise good job so far.

[anmoltrvd01]

Hi @adhiamboperes, I've addressed the requested changes by adding the test for toolbar marquee behavior in 'AudioLanguageActivityTest' and fixing the formatting issues.
Please let me know if anything else needs to be updated.
Thanks!

[adhiamboperes]

@anmoltrvd01, the new test is failing. Please fix it and run it locally. We have included the test running instructions in the installation guide of the wiki.

Hi @adhiamboperes,
I've fixed the failing test and verified it locally, all tests are now passing. I've also attached a screenshot of the successful test run for reference.
Could you please approve and re-run the workflows so the checks can complete?
Thanks!

[adhiamboperes]

Thanks @anmoltrvd01, PTAL at some final cleanup comments.

Also:

1. Don't resolve comments - the reviewer will resolve comments after verifying that they have been addressed fully.

@adhiamboperes PTAL

[adhiamboperes]

Looks good so far, thanks!

Waiting for CI to pass.

[oppiabot]

Assigning @BenHenning for code owner reviews. Thanks!

[anmoltrvd01]

PTAL when you get a chance @adhiamboperes,

I’m a bit unsure about the current CI failures. It’s been a few days and I’m not completely clear on what is still blocking the PR from passing all checks.
From my side, tests seem to be passing, but the coverage workflow is still failing. Could you please guide me on what needs to be fixed next?
Thanks!

[oppiabot]

Unassigning @anmoltrvd01 since a re-review was requested. @anmoltrvd01, please make sure you have addressed all review comments. Thanks!
