去除BottomNavigationView的Item大于3个时的动画效果

当BottomNavigation的Item超过3个时选择会有动画效果，且选中Item时文字才会显示，下面是解决方案：

sdk版本小于28时用反射解决

public class BottomNavigationViewHelper {
    @SuppressLint("RestrictedApi")
    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) {
        } catch (IllegalAccessException e) {
        }
    }
}

BottomNavigationViewHelper.disableShiftMode(navigation);

sdk版本大于等于28时置属性解决

     app:itemHorizontalTranslationEnabled="false"  
     app:labelVisibilityMode="labeled"
