    tools:context="com.reloadapp.reload.activity.IconTabsActivity">
    <item
        android:id="@+id/action_favorites"
        android:enabled="true"
        android:icon="@drawable/home_40"
        android:title="Home"
        app:showAsAction="ifRoom" />
    <item
        android:id="@+id/action_schedules"

Remove animation in bottom navigation ,use this code

navigation = (BottomNavigationView) findViewById(R.id.navigation);
        disableShiftMode(navigation);

method

public static void disableShiftMode(BottomNavigationView view) {
        BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
        try {
            Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
            shiftingMode.setAccessible(true);
            shiftingMode.setBoolean(menuView, false);
            shiftingMode.setAccessible(false);
            for (int i = 0; i < menuView.getChildCount(); i++) {
                BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
                //noinspection RestrictedApi
                item.setShiftingMode(false);
                // set once again checked value, so view will be updated
                //noinspection RestrictedApi
                item.setChecked(item.getItemData().isChecked());
            }
        } catch (NoSuchFieldException e) {
            Log.e("BNVHelper", "Unable to get shift mode field", e);
        } catch (IllegalAccessException e) {
            Log.e("BNVHelper", "Unable to change value of shift mode", e);
        }
    }
