How to do it…

Kotlin has some operators that we can use on a class. We will be overloading one of these operators to get views of our view group:

1. We can access views of a view group by overloading the get operator like this:

operator fun ViewGroup.get(position: Int): View{    return getChildAt(position)}

2. Now, in order to get a view from the view group, we can use either of the following methods:

val view = viewContainer.get(2)// where 2 is the position for the view we want to access

3. Alternatively, use the following method because we used operator overloading, and el.get(index) matches with the array-like el[index] operation:

val view = viewContainer[2]// where 2 is the position for the view we want to access
