android - AHBottomNavigation不是全宽

我将从官方的底部导航视图切换到this库。
但我注意到使用此库时，宽度与原始库不同
我错过了什么？

最佳答案

终于找到了代码。
在AHBottomNavigation.java中，有些lines会更改每个项目的宽度

if (titleState == TitleState.ALWAYS_SHOW && items.size() > MIN_ITEMS) {
    minWidth = resources.getDimension(R.dimen.bottom_navigation_small_inactive_min_width);
    maxWidth = resources.getDimension(R.dimen.bottom_navigation_small_inactive_max_width);
}

删除这些行会使该栏的行为类似于官方库。
