Unexpected Behavior with Custom ViewGroup Touch Events in Android 14
I'm not sure how to approach I'm experiencing an issue with a custom ViewGroup that I've implemented for my Android app targeting API level 34 (Android 14). The custom ViewGroup is supposed to intercept touch events to manage gesture detection, but it seems that my `onInterceptTouchEvent` method does not behave as expected when nested scroll views are present within it. Specifically, the touch events are not being intercepted correctly, leading to unexpected behavior where child views are receiving touch events even when they should be captured by the parent. I've overridden both `onInterceptTouchEvent` and `onTouchEvent` in my custom ViewGroup: ```kotlin class CustomViewGroup(context: Context, attrs: AttributeSet) : ViewGroup(context, attrs) { override fun onInterceptTouchEvent(ev: MotionEvent): Boolean { // Example logic to intercept touch events return ev.action == MotionEvent.ACTION_MOVE // Attempt to intercept only move events } override fun onTouchEvent(event: MotionEvent): Boolean { // Handle touch events if (event.action == MotionEvent.ACTION_MOVE) { // Process the move event return true } return false } override fun onLayout(changed: Boolean, left: Int, top: Int, right: Int, bottom: Int) { // Layout children // Assume proper handling of child views here } } ``` However, when I have a nested RecyclerView inside my custom ViewGroup, the `onInterceptTouchEvent` seems to be ignored when scrolling the list. I’ve also ensured that I’m returning `true` in the `onTouchEvent` for the move action, but it doesn’t seem to change the behavior. I've tested on multiple devices and emulators, and the problem persists. I've tried adding a `setOnTouchListener` to the RecyclerView to see if I could manually intercept touch events, but it didn’t help. Additionally, I confirmed that the RecyclerView is set up with `setNestedScrollingEnabled(false)`, which I thought would help in this case. I’m not sure what I’m missing or if there’s a specific interaction with nested scroll views that I should consider. Any insights or recommendations would be greatly appreciated! My development environment is macOS. Any ideas what could be causing this? This is for a mobile app running on Debian. I'd be grateful for any help.
