You want to start new activity. You can read more on initiating new Activities at Android documentation.

However you might consider making a "normal" application screen and call another Activity for login purposes instead of having a login page and redirection.

So if page/Activity_A requires user to be logged in, you call LoginActivity with startActivityForResult and get true/false if user has properly logged in.

create an Intent and pass the intent to startactivty method. ake sure your activity should be defined in manifest file

Read about Intents

intents are used to start new activity

Activity is the super class that represents each of your view corresponding to your layout

in Professional Android App Dev- WROX by Retro Meier gives good examples for this in a chapter for Intents and Broadcast.
