您可以覆盖一些默认值文本：

<dimen name="design_bottom_navigation_text_size" tools:override="true">24sp</dimen> 
<dimen name="design_bottom_navigation_active_text_size" tools:override="true">24sp</dimen> 

对于图标（32dp）：

final DisplayMetrics displayMetrics = getResources().getDisplayMetrics(); 
    BottomNavigationView bottomNavigationView = (BottomNavigationView) configurationActivity.findViewById(R.id.bottom_navigation_view); 
    BottomNavigationMenuView menuView = (BottomNavigationMenuView) bottomNavigationView.getChildAt(0); 
    for (int i = 0; i < menuView.getChildCount(); i++) { 
     final View iconView = menuView.getChildAt(i).findViewById(android.support.design.R.id.icon); 
     final ViewGroup.LayoutParams layoutParams = iconView.getLayoutParams(); 
     layoutParams.height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 32, displayMetrics); 
     layoutParams.width = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 32, displayMetrics); 
     iconView.setLayoutParams(layoutParams); 
    }
