lateinit keyword is used for late initialization of variables. -->Var is used for creating variable -->binding is a variable name -->What is the meaning of this (: ActivityMainBinding) Some people said that is class and some said that created an object, I am too confused. -->Again write the variable name binding and initialize the ActivityMainBinding.inflate(layoutInflater) -->What is the meaning of these keywords ActivityMainBinding.inflate(layoutInflater)-->Last Question is what is the meaning of this setContentView(binding.root)
lateinit var binding: ActivityMainBinding binding = ActivityMainBinding.inflate(layoutInflater) setContentView(binding.root)
CodePudding user response：
So binding is used to bind your views.
lateinit var binding :ActivityMainBinding ->here :ActivityMainBinding is a generated class which contains layout ids etc.
binding = ActivityMainBinding.inflate(layoutInflater) -> here we are inflating layout.
setContentView(binding.root)-> here we are setting our layout with class when class runs.Means here we are setting what we see when this activity runs.
CodePudding user response：
ActivityMainBinding=This class is auto generated by system using your xmlName Binding Keyword
ActivityMainBinding.inflate(layoutInflater)=It inflate the view hierarchy and bind the object to it.
binding.root=To Get a reference to the root view by calling the getRoot() method and pass this root view in setContentView() method to attach that root view to Activity
