使用ViewBinding后button按钮失效

今天学习《第一行代码》时使用ViewBinding代替findViewById()，发现代替以后button无法激活intent，从https://www.jianshu.com/p/86f780f3aabd 找到了问题所在

问题代码

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        Log.d(tag,"onCreate")
        val binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(R.layout.activity_main)

        binding.startNormalActivity.setOnClickListener {
            val intent = Intent(this, NormalActivity::class.java)
            startActivity(intent)
        }
        binding.startDialogActivity.setOnClickListener {
            val intent = Intent(this, DialogActivity::class.java)
            startActivity(intent)
        }
    }

关键就是在setContentView(R.layout.activity_main)这行代码出现了问题

tips：这行代码是自动生成的

修改

需要改为在setContentView()前进行binding绑定
val binding = ActivityMainBinding.inflate(layoutInflater)

然后setContentView改为setContentView(binding.root)

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        Log.d(tag,"onCreate")
        val binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
        ...
    }
