Im a beginner in Android Studio and have a school project where I have to create an login screen with password and username. When trying to follow some instructions online I get an error even though I have done the same as the instructor. Can you see what I have done wrong?

CodePudding user response：

Your code is in Kotlin while the video you linked uses Java, so the error indicates that the onClickListener is not following Kotlin syntax properly.

The equivalent in Kotlin is:

logIn.setOnClickListener {
    // Do some work here
}

or

button.setOnClickListener(object : View.OnClickListener {
    override fun onClick(view: View?) {
        // Do some work here
    }
})

Both will behave similarly. See alternative ways here.

// declare

private lateinit var logIn: Button

// cast

logIn = findViewById(R.id.logIn)

// execute the func you want

logIn.setOnClickListener {
    executeLogInApi()
}
