Login screen: Save username and password

Question

After deciding to get some exposure to android app, i started playing with it but being new to java and new environment is a good learning curve. However after many hours I was able to get the basic android app going. Now I have another dilemma. I dont have a login screen. I can connect to database just fine but I want users to enter their login one time when they start the app. I have these questions

1. Any good tutorials that I can find where there is a login screen that I can add on top of the work I already got done and once they login, they get directed to those files

2. How do I set the menus. Like if the users setup the login one time and later on they want to change it and use another login, how would I go about setting those?

Any links to good tutorials about this will be very appreciated

Answer 1

If they are logged into the app and wan to logout and in with another user name, I would recommend creating a menu option to Sign Out which would take them back to the login screen. http://developer.android.com/guide/topics/ui/menus.html

For the login screen itself, you could use a LinearLayout or RelativeLayout . It's really up to you, though.

As far as links to tutorials, the two above would likely help, but they don't necessarily cover exactly what you're wanting. Google can always be a good friend, though.
