viewBinding

1. 配置

android{
buildFeatures{
        //dataBinding = true
        // for view binding :
         viewBinding = true
    }
}

2. 资源名的变化 布局文件的名称为 result_profile.xml： 使用名为 ResultProfileBinding

3 使用

private lateinit var binding: ResultProfileBinding  //布局文件名

    override fun onCreate(savedInstanceState: Bundle) {
        super.onCreate(savedInstanceState)
        binding = ResultProfileBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)
    }



binding.nametextview.text = "nihaome"  //id为 nametextview 的 view
    binding.gobutton.setOnClickListener { viewModel.userClicked() }
