hide/show when recycler scroll inside Conductor view doesn't work

If you use the RecyclerView inside a CoordinatorLayout this should suffice: bottomNavigation.setBehaviorTranslationEnabled(true);

I have a recyclerView inside a CoordinatorLayout but it does't work. Am I forgetting something?

MainActivity

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.main_view)
        initRoute(savedInstanceState)
        initNavBar()
 }

val navigationAdapter = AHBottomNavigationAdapter(this, R.menu.navigation)
        navigation?.let { safeNave ->
            navigationAdapter.setupWithBottomNavigation(safeNave)
            safeNave.isBehaviorTranslationEnabled = true
            safeNave.setOnTabSelectedListener { position, wasSelected ->

                when (position) {
                    1 -> router.pushController(RouterTransaction.with(FeedController()))

                    2 -> router.pushController(RouterTransaction.with(HostFormController()))

                    3 -> router.pushController(RouterTransaction.with(ContentController()))

                    4 -> router.pushController(RouterTransaction.with(LessonController()))

                    5 -> router.pushController(RouterTransaction.with(AccountController()))

                }
                true
            }
    }

Main XML

        </android.support.design.widget.AppBarLayout>

            android:id="@+id/baseContainer"

            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    </LinearLayout>

    <com.aurelhubert.ahbottomnavigation.AHBottomNavigation
        android:id="@+id/navigation"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="0dp"
        android:layout_marginStart="0dp"

        app:layout_scrollFlags="scroll|enterAlways"
        app:menu="@menu/navigation" />
</android.support.constraint.ConstraintLayout>

And finnaly, the recycler who has ID activeFormRecycleView that might hide/show the menu.

Your AHBottomNavigation has this layout_behavior:

    app:layout_behavior="org.secfirst.umbrella.component.BottomNavigationBehavior"

It probably is overriding the required behavior or conflicting with the library

Also, having 2 RecyclerViews in the same layout isn't recommended and it could also be the cause of the issue. Try using a single RecyclerView that is sectioned. You can use this library, or create your own implementation

@jahirfiquitiva totally make sense. The problem was two recycleView. I got rid of one of them and works fine. Thanks.
