SchoolListing.kt

This interface is used to identify models to use in a recycler view, to prevent adding of other type of models in array except for models that implements SchoolListing

interface SchoolListing

Adding data to array

val tempArray = ArrayList<SchoolListing>()
        tempArray.add(HeadingModel("Principal"))
        tempArray.add(ListItemModel("Yogesh Paliyal"))

        tempArray.add(HeadingModel("Staff"))
        tempArray.add(ListItemModel("Sachin Rupani"))
        tempArray.add(ListItemModel("Suraj Vaishnav"))
        tempArray.add(ListItemModel("Himanshu Choudhan"))
        tempArray.add(ListItemModel("Pramod Patel"))
        tempArray.add(ListItemModel("Bharath"))
        tempArray.add(ListItemModel("Sanjay"))
        tempArray.add(ListItemModel("Surendra Singh"))


        tempArray.add(HeadingModel("Students"))
        tempArray.add(ListItemModel("Bhoma Ram"))
        tempArray.add(ListItemModel("Deepak"))
        tempArray.add(ListItemModel("Sohan"))
