如上图所示，我具有此按钮导航视图，每次启动应用程序时，默认情况下都会突出显示类别"标签，但是我想在启动应用程序时突出显示首页"标签，有人帮我摆脱困境吗?

As shown above, I have this button navigation view, when ever I launch my application, in default my "Catagories" tab gets highlighted, but I want to get my "Home" tab get highlighted when i launch my application, can anyone help me get out of it?

推荐答案

尝试使用您的BottomNavigationView的setSelectedItemId()方法，如下所示

try this use setSelectedItemId() method of your BottomNavigationView like this

BottomNavigationView bottomNavigationView;
bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottomNavigationView);
bottomNavigationView.setSelectedItemId(R.id.home_menu);

或像这样使用您的视图寻呼机的viewPager.setCurrentItem();

or use viewPager.setCurrentItem(); of your view pager like this

viewPager.setCurrentItem(2);
