Hello,please Help. Validation don't work.Where can a bug be ? After clicking the registerUser, the second activity will not start.Thanks https://pastebin.com/E9cpgVhd https://pastebin.com/gRAitRD8

Please note that : " regFirstName = findViewById(R.id.regFirstName) regLastName = findViewById(R.id.regLastName) regEmail = findViewById(R.id.regEmail) regPassword = findViewById(R.id.regPassword) regCnfpass = findViewById(R.id.regCnfpass) registerUser = findViewById(R.id.registerUser) " can be removed if you import "import kotlinx.android.synthetic.main.{yourActivity}.*"

must be a really really small mistake, in your Activity layout or setup. Because I don't see an error in your code. The only difference between what I see and a working example I have maybe is the decorator after "this" in your Main Activity's intent

no, I did not try it

can you delete the finish() line ?

Yes, without changing the same

if you print a message after you finished the Activity ... 😄

finish () line has been deleted but without change

did you also remove the annotation after the context when you create the intent ?

I will try to

If I were you I would take this line out of the click listener : val intent = Intent(this@RegisterActivity, DataSave::class.java) and remove "@RegisterActivity", let me know if that works

without any change
