KOTLIN :如何使用ViewBinding在函数中调用视图

android {
    ...
    viewBinding {
        enabled = true
    }
}

<LinearLayout
    ...
    android:id="@+id/linear_layout"
    ...>
    ...
</LinearLayout>

import com.example.app.databinding.ActivityMainBinding

class MainActivity : AppCompatActivity() {
    private lateinit var binding: ActivityMainBinding

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

        // 在函数中调用视图
        binding.linearLayout.doSomething()
    }
}

fun LinearLayout.doSomething() {
    // 在函数中对视图进行操作
    ...
}
