这是我的代码：

public final class newBottomNav extends BottomNavigationView {
    private final Context context;
    private Typeface fontFace = null;

    public newBottomNav(Context context,AttributeSet attrs){
        super(context,attrs);
        this.context = context;
    }

    @SuppressLint("RestrictedApi")
    @Override
    protected void onLayout(boolean changed,int left,int top,int right,int bottom){
        super.onLayout(changed,left,top,right,bottom);
        final ViewGroup bottomMenu = (ViewGroup)getChildAt(0);
        final int bottomMenuChildCount = bottomMenu.getChildCount();
        BottomNavigationItemView item;
        View itemTitle;
        Field shiftingMode;

        for(int i=0; i<bottomMenuChildCount; i++){
            item = (BottomNavigationItemView)bottomMenu.getChildAt(i);
            //this shows all titles of items
            item.setChecked(true);
            //every BottomNavigationItemView has two children,first is an itemIcon and second is an itemTitle
            itemTitle = item.getChildAt(1);
            //every itemTitle has two children,first is a smallLabel and second is a largeLabel. these two are type of AppCompatTextView
            ((TextView)((BaselineLayout) itemTitle).getChildAt(0)).setTextSize(10);
            ((TextView)((BaselineLayout) itemTitle).getChildAt(0)).setGravity(Gravity.CENTER_HORIZONTAL);
            ((TextView)((BaselineLayout) itemTitle).getChildAt(1)).setTextSize(10);
            ((TextView)((BaselineLayout) itemTitle).getChildAt(1)).setGravity(Gravity.CENTER_HORIZONTAL);
        }
    }

    @SuppressLint("RestrictedApi")
    public static void removeNavigationShiftMode(BottomNavigationView view) {
        BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
        menuView.setLabelVisibilityMode(LabelVisibilityMode.LABEL_VISIBILITY_LABELED);
        menuView.buildMenuView();
    }
