@Shawn may I know what is the correct or best way of doing it?

What does

TextUtils.isEmpty(email)

do? Is it the same as

string.isEmpty()

? If yes, then you can write

buttonRegister.isEnabled = email.isNotEmpty() && password.isNotEmpty() && confirmPassword.isNotEmpty()

I suppose

TextUtils.isEmpty

is from Android

android.text.TextUtils

, so it’s like isNullOrEmpty(), but for non-null variables in Kotlin it can be replaced with isNotEmpty()

@Pavlo Liapota

TextUtils

is a package in Android.

so instead you can use isEmpty(), isNotEmpty() or isNullOrEmpty(), depending on your use case and types

how about:

buttonRegister.isEnabled = listOf(email, password, confirmPassword).none { it.isNullOrEmpty() }

?

@digitalsanctum that’s real fancy. I like that.
