Accessibility: Missing labels on Theme options and input field improvements

[AnaFerreira015]

Hi! I’m Ana Ferreira, a Master's student in Computer Science.

As part of my research on mobile accessibility, I am analyzing open-source Android applications to help identify and correct accessibility barriers so users can utilize assistive technologies (like TalkBack) more effectively.

I’ve been exploring Inflation Calculator and found a specific issue in the Theme Selection Menu, so I wanted to propose a fix.

1. The Issue

When opening the Theme options (menu/dialog), the Radio Buttons for selecting the mode (System, Light, Dark) present the following behavior:

• Current behavior: The selection buttons lack a programmatic link to their visible labels. TalkBack announces them simply as "Radio Button" (or "Unlabelled"), violating WCAG 4.1.2 (Name, Role, Value).
• Impact: Blind users cannot determine which option they are selecting (System, Light, or Dark) without guessing based on position.

2. Proposed Solution

To fix this, I suggest ensuring the RadioButton elements have an android:text attribute directly on them, or use android:contentDescription matching the visible text.

Code snippet / XML suggestion:

<RadioButton
    ...
    android:text="@string/theme_dark" /> ```

### 3. Additional fixes (Need your input)

I have identified **3** other categories of accessibility improvements, particularly on the Main Screen.

**To avoid spamming your notification feed, how would you prefer I submit these?**

- [ ]  **Option A:** List them all here in this issue (I can update the comment below).
- [ ]  **Option B:** Open separate issues for each specific problem.

I can provide detailed fixes for these upon request.

Please let me know your preference, and I will proceed accordingly.

Best regards,
