Answer 1

com.ashokvarma.bottomnavigation.BottomNavigationBar  这可不是现成的写法, 楼主是写了这么一个类吗?

Answer 2

进来看一下~！请问<br 跟html语言的</br>是不是都是换行的意思？

Answer 3

com.ashokvarma.bottomnavigation.BottomNavigationBar 你看看这个报名， 再看看你自己的包名package com.ishihara.satomi;  我怀疑你是直接考过来的 当然找不到。
把BottomNavigationBar 的路径改成你拷贝过来的BottomNavigationBar.java放的路径 就能找的到了  按着ctrl加鼠标左键放上去  能跳转就是找到了 跳转不了就是没找到

Answer 4

com.ashokvarma.bottomnavigation.BottomNavigationBar
这个类源代码里面或jar文件里面有吗？

Answer 5

com.ashokvarma.bottomnavigation.BottomNavigationBar是一个第三方开源的控件，你要用就要先在build.gradle导包
