Answer 1

No need for

setContentView(binding.getRoot());

DataBinding.setContentView() is enough.

Answer 2

Or u can code it Like I do. Also Im using kotlin

private lateinit var binding: ActivityMainBinding
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)
