[Android] Wrong user's tap area in overlay

[v-korotkov]

Hi!

I use:
"react-native": "0.72.4",
"react-native-navigation": "^7.37.0",

I faced an annoying problem with overlays on Android. I show an overlay with a not full-screen view with interceptTouchOutside: false. For example, this view is {x: 0, y: 500, width: 100, height: 100}

When the user tries to tap the overlay the app receives a tap through the overlay (under it). Also, when the user tries to tap an area {x: 0, y: 0, width: 100, height: 100} through overlay (using interceptTouchOutside: false) it is blocked for taps.

It works well on iOS. Also, it worked well on older versions of react-native and react-native-navigation.

I found a problem in react-native-navigation/lib/android/app/src/main/java/com/reactnativenavigation/utils/MotionEvent.kt

When we use the old version of the code our not full-screen overlay view performs getHitRect in the full-screen parent, so it works correctly.

view ?: return false
view.getHitRect(hitRect)
return hitRect.contains(x.toInt(), y.toInt())

However, when we started to use the new version of the code, we had an issue. It happens cause we use a child of this view from getChildAt instead of the original view for the getHitRect method.

val viewGroup = (view as? ViewGroup)?.getChildAt(0) as? ViewGroup ?: view
viewGroup?.getHitRect(hitRect)
return hitRect.contains(x.toInt(), y.toInt())

Android View getHitRect
The documentation says that getHitRect - Hit rectangle in parent's coordinates.

Therefore, when we use the original view for getHitRect, it calculates the hit for his full-screen parent, but when we use a view's child, it calculates the hit for the original view as a parent.

So, when the user taps on {x: 50, y: 550} coordinates on the screen, it will be just {x:50, y:50} in the not full-screen parent, and the blocking tap area for overlay will be translated to the top of the screen in the wrong place.

Additional changes: typo in REACT_NATVE_VERSION_MINOR

I prepared changes to fix this issue. Let's review and apply ones.

Had similiar issues on android, this fixed! EDIT: its not consistent, can't recommand as an actual fix!

Could you please add the specific versions of "react-native" and "react-native-navigation" where it was fixed and works fine now? I have a stable reproduction of this issue since updating to the latest versions of these modules ("react-native": "0.72.4" and "react-native-navigation": "^7.37.0"). Therefore I have to use a workaround in my code to avoid this issue in the "react-native-navigation" module.

I know that the current code has already had changes that trying to fix a similar problem on Android (problem, PR, commit), but it is obviously the wrong way to fix it because it adds a new issue to the latest versions.

If we want to resolve the old problem too we should consider updating to the latest version or suggest a more specific way to detect the case when we should use child view instead of the original view instead of just always using it by default.

Is third commit [4634988](REACT_NATIVE_VERSION_MINOR typo) required in this fix ?

No, this is not needed for the problem fix, it was made just as an additional typo fix.
