2.1 Input Types

Input (items) of a list can be arbitrary Kotlin object. We use an adapter to extract data from this Kotlin object, then assign object fields'value to the views in each row of ListView.

For example:


class Note {

    var id: Int? = null
    var title: String? = null
    var content: String? = null

    constructor(id: Int, title: String, content: String) {
        this.id = id
        this.title = title
        this.content = content
    }
}

Class for Kotlin object is called data model.
