From a14efe215ab2fb863ef4f3f887d0f43dcdca09c8 Mon Sep 17 00:00:00 2001 From: Odeya Twito Date: Sun, 8 Feb 2026 13:12:22 +0200 Subject: [PATCH 1/3] fix(android): Make overlay container properly pass through touches when interceptTouchOutside is false Fixes #4953, #7674 ## Problem On Android, overlays with `interceptTouchOutside: false` were still blocking touch events from reaching underlying views, despite the OverlayTouchDelegate correctly checking the flag and returning false from onInterceptTouchEvent. ## Root Cause The issue was in Navigator.java where overlaysLayout (a CoordinatorLayout) was added on top of all content (z-index 2). In Android's touch event system, ViewGroups higher in z-order receive touches first. Even though ComponentLayout's onInterceptTouchEvent() correctly returned false, the parent overlaysLayout container was still consuming touch events before they could fall through to the rootLayout below. ## Solution Created OverlayContainer - a custom CoordinatorLayout that: 1. Overrides onInterceptTouchEvent() to check each child ComponentLayout 2. Delegates to child's onInterceptTouchEvent() which uses OverlayTouchDelegate 3. Returns false when no overlay wants to intercept (interceptTouchOutside: false) 4. Overrides dispatchTouchEvent() to return false for ACTION_DOWN when not intercepting, allowing the touch to fall through to views below ## Changes - Added OverlayContainer.kt - custom container that respects interceptTouchOutside - Updated Navigator.java to use OverlayContainer instead of CoordinatorLayout - Added comprehensive unit tests (OverlayContainerTest.kt) - Updated documentation to clarify Android behavior ## Testing - Unit tests verify touch passthrough behavior - Tests cover single overlay, multiple overlays, and edge cases - Playground app testing recommended before merge
