error: What does No resource identifier found for attribute 'latout_height' in package 'android' mean?

This is due to a spelling error.

If layout_height instead of latout_height, won't the errors disappear?

If you don't know the cause of the error message after reading it, I think it's one way to google it with an error message and find out when the error message occurs.If you find out the pattern of occurrence in due course, you may be aware of the mistake yourself.
