BottomNavigationView items not aligning properly in ConstraintLayout with motion layout

android layout bottom-navigation xml

I'm wondering if anyone has experience with I'm maintaining legacy code that I'm working on a personal project and I'm encountering a layout issue where my `BottomNavigationView` items are not aligning correctly when used within a `ConstraintLayout`, particularly utilizing MotionLayout for transitions... I expect my items to be centered, but they appear off to one side. I've tried to set the `layout_constraintWidth_default` to `wrap` and `layout_constraintHeight_default` to `wrap`, but the alignment is still off. Hereโ€™s how I set it up: ```xml <androidx.constraintlayout.motion.MotionLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <BottomNavigationView android:id="@+id/bottom_navigation" android:layout_width="0dp" android:layout_height="wrap_content" app:layout_constraintStart_toStartOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintBottom_toBottomOf="parent" app:menu="@menu/bottom_nav_menu" /> </androidx.constraintlayout.motion.MotionLayout> ``` Additionally, I've set up a simple menu resource: ```xml <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/navigation_home" android:icon="@drawable/ic_home" android:title="Home" /> <item android:id="@+id/navigation_dashboard" android:icon="@drawable/ic_dashboard" android:title="Dashboard" /> <item android:id="@+id/navigation_notifications" android:icon="@drawable/ic_notifications" android:title="Notifications" /> </menu> ``` I've also attempted to use `layout_width` as `match_parent`, but that leads to some additional unwanted padding on the sides. Sometimes, the items seem to overlap or get cut off depending on the deviceโ€™s screen size. Iโ€™m testing this on a Pixel 5 with API level 30. Has anyone faced a similar issue, or can anyone suggest an alternative approach to ensure proper alignment of the BottomNavigationView within a MotionLayout? Any insights would be greatly appreciated! Thanks in advance!
