Browse an instance of Tab's View on Android

Hello sekitaka.

I had to set the highlight of Showcase View (https://github.com/amlcurran/ShowcaseView) on the tab in the Android app. To set ShowcaseView highlighting, I needed to specify an instance of the View of interest, and I looked at how to get an instance (of a subclass of View) for each Tab.

TabLayout tabLayout = (TabLayout)findViewById(R.id.tab_layout);
ViewGroup viewGroup = (ViewGroup)tablayout.getChildAt(0); //0 can be fixed
int tabPosition = 0; //Index of the tab you want to get
View tabView = viewGroup.getChildAt(tabPosition); //Get a View instance of a tab
