有没有办法禁止 BottomNavigationView 实现轻微放大所选项目的文本/图标？

Answer 1

您可以覆盖 Text 的一些默认值:

<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);
    }
