kotlin-android-extensions - Kotlin-Android我们可以在Class上实现OnClickListener吗？

Question

我从Kotlin开始，如果我在Activity类上实现onClick似乎不会触发它

class MainActivity : AppCompatActivity(), View.OnClickListener{

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        tvTitle.text = "Hi There"

//        tvTitle.setOnClickListener { this } // NOT WORKING??
        tvTitle.setOnClickListener { doSomething() }
    }


    override fun onClick(v: View) {
        Log.d("click", "Hello")
    }

    fun doSomething(){
        Log.d("do", "Something")
    }
}

我使用的Android Studio 3.0的kotlin_version为1.1.51，请先谢谢

尝试这个

class MainActivity : AppCompatActivity(), View.OnClickListener{

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    tvTitle.text = "Hi There"

    tvTitle.setOnClickListener(this)
   //   tvTitle.setOnClickListener { doSomething() }
}


override fun onClick(v: View) {
    Log.d("click", "Hello")
}

fun doSomething(){
    Log.d("do", "Something")
}
}
