回答1:

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

回答4:

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.
