将ActivatedRouteSnapshot注入组件不起作用(也没有注入ActivatedRoute).这里的堆栈跟踪:

在组件中,ActivatedRouteSnapshot注入如下:

constructor([...], private router: Router,

}

ActivatedRouteSnapshot提供于app.component.ts:

有没有办法在Android Studio中显示所有源代码选项卡一个水平线(在标签栏中)并滚动它们？

当Android Studio中打开的源代码选项卡太多时,其中一些会移动到代码编辑窗口右上角的下拉列表中.移动到此下拉列表的选项卡不再显示在选项卡栏中.

标签栏中的选项卡可以使用鼠标滚轮滚动,但只能滚动到下拉列表中.

有没有办法删除下拉列表并保留标签栏中的所有选项卡？

如何循环浏览Android RecyclerView中的项目？

我想要一个水平滚动的RecyclerView.当结束到达右侧时,它只需通过重新启动项目列表继续滚动.同样在左边.

例如:
项目清单:0,1,2,3,4,5,6,7,8,9
起始视图显示:0,1,2,3,4,5,6,7
滚动5个项目后右:5,6,7,8,9,0,1,2
向左滚动2个项目后:8,9,0,1,2,3,4,5
