Revert - Fix TalkBack not correctly narrating RadioButtons with Content

[devanathan-vaithiyanathan]

Issue details:

A regression was introduced by PR #34521 on Android. It set RadioButton accessibility metadata (ClassName, Checkable, Checked) on AccessibilityNodeInfoCompat during TalkBack. The bool setter for Checked no longer exists in AndroidX Core 1.17.x (API changed), causing a MissingMethodException at runtime. This mainly affects .NET 10 MAUI packages that compile against AndroidX Core 1.16.0.3.

Description of changes:

Fully reverts PR #34521. Removes the IRadioButton accessibility block (ClassName, Checkable, Checked) and the cached s_radioButtonClassName field from SemanticExtensions.cs. Reverts RadioButton.UpdateSemantics back to using ContentAsString() and removes the GetSemanticDescriptionFromContent() and TryGetSemanticDescription() helpers. Also removes the two device tests added for issue #34322 and their helper methods.

Issues Fixed

Fixes #35584

Pre-Flight — Context & Validation

Pre-Flight Summary

PR: #35625
Platform for testing: Android
Gate: Already completed externally — PASSED. Gate output was not modified.

Context

PR #35625 changes RadioButton accessibility behavior by reverting the semantic-content extraction and Android semantic-node updates introduced by the earlier RadioButton accessibility fix. GitHub CLI authentication is unavailable in this environment, so context was gathered from local repository state, public GitHub API access where available, and full source/diff review.

Changed Files

• src/Controls/src/Core/RadioButton/RadioButton.cs
• src/Core/src/Platform/Android/SemanticExtensions.cs
• src/Controls/tests/DeviceTests/Elements/RadioButton/RadioButtonTests.cs

Code Review Summary

Verdict: NEEDS_CHANGES
Confidence: high

The PR appears over-broad: it removes the original accessibility fix and its regression tests instead of addressing likely narrow regressions. The main risks are reintroducing type-name announcements for templated/view-content RadioButtons and losing Android TalkBack role/state for templated RadioButtons.

Try-Fix Inputs

Problem: Preserve correct RadioButton accessibility semantics for templated/view-content RadioButtons on Android while avoiding regressions from the previous implementation.

Target files:

• src/Controls/src/Core/RadioButton/RadioButton.cs
• src/Core/src/Platform/Android/SemanticExtensions.cs
• src/Controls/tests/DeviceTests/Elements/RadioButton/RadioButtonTests.cs

Relevant failure modes:

• View-based RadioButton content should expose child label/semantic text, not a CLR type name.
• Explicit SemanticProperties.Description should not be overwritten by content-derived semantics.
• Android templated RadioButtons should expose radio-button role and checked state to TalkBack.
• If no text is found in view-based content, fallback should continue to Value or ContentAsString() rather than returning null.

Code Review — Deep Analysis

Code Review — PR #35625

Independent Assessment

What this changes: PR #35625 removes the RadioButton semantic-content extraction added by the prior accessibility fix, removes Android AccessibilityNodeInfoCompat radio-button role/state population for IRadioButton, and deletes the corresponding Android device regression tests.
Inferred motivation: The PR appears to be a revert of PR #34521, likely due to a regression in that fix, but the available local/GitHub metadata did not expose a concrete replacement strategy.

Reconciliation with PR Narrative

Author claims: GitHub CLI authentication was unavailable; public API data was partially accessible via curl, but the review is based primarily on local diff/source context and PR metadata.
Agreement/disagreement: The diff does simplify the code, but it also reintroduces the original accessibility regression for templated/view-content RadioButtons and removes the tests proving the behavior.

Findings

❌ Error — Issue #34322 behavior is reintroduced for view-based RadioButton content

src/Controls/src/Core/RadioButton/RadioButton.cs changes UpdateSemantics() back from semantic extraction to ContentAsString(). For Content values that are IView/layout instances, ContentAsString() ultimately uses ToString(), so a templated RadioButton with content like VerticalStackLayout { Label("Dog") } can expose a type name instead of the intended accessible label.

❌ Error — Android templated RadioButtons lose explicit role/state semantics

src/Core/src/Platform/Android/SemanticExtensions.cs removes the IRadioButton block that set ClassName, Checkable, and Checked on AccessibilityNodeInfoCompat. Native non-templated Android radio buttons may still get this from AppCompatRadioButton, but templated RadioButtons use container views and need explicit role/value information for TalkBack.

❌ Error — Regression tests are deleted without replacement

src/Controls/tests/DeviceTests/Elements/RadioButton/RadioButtonTests.cs removes tests for templated RadioButton semantic label extraction and explicit semantic-description precedence. A revert might be justified if PR #34521 introduced a distinct bug, but this PR does not preserve coverage for the original issue or add coverage for the alleged regression.

⚠️ Warning — The prior implementation likely had a surgical bug rather than requiring a wholesale revert

The removed GetSemanticDescriptionFromContent() returned null when Content is IView but no textual semantic description was found, preventing fallback to Value or ContentAsString(). That is a small control-flow bug that can be fixed by falling through when recursive extraction fails.

Failure Modes

• Templated RadioButton with Content = new VerticalStackLayout { Children = { new Label { Text = "Dog" } } }: accessible description may become Microsoft.Maui.Controls.VerticalStackLayout instead of Dog.
• Android templated RadioButton: TalkBack may not announce role/state (radio button, checked/not checked) because the platform view is not an AppCompatRadioButton.
• Content is IView with no text but Value = "Dog": the prior fix can return null instead of falling back to Value unless corrected surgically.

Blast Radius

Affects MAUI RadioButton accessibility on Android and cross-platform semantics for templated/view-content RadioButtons. Native non-templated string-content RadioButtons are lower risk.

Devil's Advocate

The PR may be responding to a real regression from PR #34521, especially around Android native role duplication or the null-return fallback path. However, the broad revert removes both the useful semantic extraction and the Android templated role/state support, so the safer path is a narrower alternative fix.

Verdict: NEEDS_CHANGES

Confidence: high
Summary: The PR reverts a legitimate accessibility fix and deletes its tests. A better candidate should preserve view-content semantic extraction, preserve Android role/state for templated RadioButtons, and fix any regression surgically.

Try-Fix Hints

• Root problem: retain RadioButton accessibility semantics while avoiding regressions introduced by the previous broad implementation.
• Target files: src/Controls/src/Core/RadioButton/RadioButton.cs, src/Core/src/Platform/Android/SemanticExtensions.cs, src/Controls/tests/DeviceTests/Elements/RadioButton/RadioButtonTests.cs.
• Candidate direction: make GetSemanticDescriptionFromContent() fall through to Value/ContentAsString() when recursive extraction from IView fails.
• Candidate direction: apply Android AccessibilityNodeInfoCompat radio-button role/state only for non-native/templated RadioButtons, avoiding duplication on AppCompatRadioButton.

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix	Preserve RadioButton accessibility fix; add fallback when view-content semantic extraction fails; guard Android role/state injection to non-native platform views	✅ PASS	2 files	Better than PR #35625 because it keeps the accessibility behavior and regression tests instead of reverting them wholesale.
PR	PR #35625	Broad revert of RadioButton semantic extraction, Android IRadioButton semantic node info, and regression tests	✅ PASSED (Gate)	3 files	Gate passed, but code review found it reintroduces the accessibility regression.

Cross-Pollination

Model	Round	New Ideas?	Details
maui-expert-reviewer	1	Yes	Surgical preserve-and-fix candidate: fall through from failed view-content extraction and guard Android native radio-button role/state duplication.

Exhausted: No — stopped because Candidate #1 passed the Android regression test command and is materially better than the PR's current broad revert.
Selected Fix: Candidate #1 — Retains correct accessibility semantics while addressing likely regressions narrowly.

Report — Final Recommendation

Comparative Report - PR #35625

Candidates compared

Rank	Candidate	Regression result	Assessment
1	try-fix-1	PASS	Best candidate. It preserves the RadioButton accessibility fix and tests while narrowly addressing the Android regression by falling back only when semantic extraction finds no text and avoiding radio-button node-state injection for native CompoundButton platform views.
2	pr-plus-reviewer	Not independently rerun	Good direction and effectively converges on the same surgical approach as try-fix-1, but it is a reviewer-derived sandbox candidate rather than the empirically tested Step 5a candidate.
3	pr	Gate PASSED	The submitted PR fixes the immediate Android gate scenario but is over-broad: it reintroduces the templated RadioButton accessibility regression by using ContentAsString() for view content, removes Android role/state semantics for templated RadioButtons, and deletes regression tests.

Analysis

The raw PR should not win because the expert review found a concrete accessibility regression on an added/modified diff line. ContentAsString() is not safe for templated RadioButtons with view content because it can announce a CLR type name instead of meaningful child text, which was the behavior fixed by the earlier accessibility change.

pr-plus-reviewer is materially better than the raw PR because it applies the expert reviewer's feedback: keep semantic extraction and fix only the Android-specific problematic path. However, among the non-raw candidates, try-fix-1 has the same surgical design and has an explicit Android device-test PASS from STEP 5a.

Winner

try-fix-1 is the single winning candidate. It is the highest-ranked candidate with passing regression evidence and avoids both the Android crash/regression targeted by PR #35625 and the accessibility regression reintroduced by the submitted PR.

Future Action — alternative fix proposed (try-fix-1)

Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against automatically generated candidates and selected try-fix-1 as the strongest fix.

Why: try-fix-1 wins because it passed the Android regression test and fixes the issue surgically while preserving the templated RadioButton accessibility behavior and tests. The raw PR passes the gate but reintroduces a known accessibility regression; pr-plus-reviewer converges on the same approach as try-fix-1 but lacks separate Step 5a regression evidence.

Please consider applying the candidate diff below (or use it as guidance). Once you push an update, this workflow will re-trigger and re-evaluate.
