I want to toast the username out when the use log in.
However, when I tried to click on the login button,
it gave me force close.
I look at the logcat
,but nothing shows up.
This coding is saying.
it will toast the username depending on what name I've input in the login screen.
there wouldn't be any password.
I don't know what is wrong with my code.
Can someone help me out?
