Android Studio Kotlin Intent to another activity

Question

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

    btnLogin.setOnClickLister {
        val intent = Intent(this, homemenu::class.java)
        startActivity(intent)
    }
} }

I have set the button for the Intent function. But it is still an error how can I fix this. The task I just only want the button after click it will head to another activity. appreciate for helping

The error message explains itself. Where did you get `btnLogin`? It is not defined. — Ricky Mo, Jan 24 '22 at 05:08
You need to use [findViewById()](https://developer.android.com/reference/android/app/Activity#findViewById(int)) or [view binding](https://developer.android.com/topic/libraries/view-binding) — Ricky Mo, Jan 24 '22 at 05:10

It is because btnLogin is not defined.

You should define btnLogin (from activity_main xml)

val btnLogin = findViewById(R.id.btnLogin) as Button

Rest is good.

Sounds good. You can define like this, too. lateinit var btnLogin: Button onCreated(..) {} – KpStar Jan 24 '22 at 05:20
