我在 Android 代码中做错了什么？

Question

I've followed a tutorial for a basic local login screen and despite following the tutorial exactly, I've hit some errors. I don't know exactly what they mean or how to solve them, could anybody help out?

Thank you.

Answer 1

Your btn.setOnClickListener(View.OnClickListener) requires View.OnClickListener object but you're passing it DialogInterface.OnClickListener object. Hence why your code doesn't compile.

Answer 2

You have confused the View.OnClickListener with the DialogInterface.OnClickListener . You have also confused pasting text with posting blurry low res images of code in the cloud:-D

Answer 3

Use new View.OnClickListener . It is different the DialogInterface.OnClickListener which you probably imported.
