From the link Maurits gave, you can also have a look at the putExtras methods.

See more info here and search for putExtra (the URL doesnt look good on SO)

*Edited:

From Donal Rafferty post, I think I understand now what you mean in the OP.

What you can do is the below:

String theClass = "Login";
StringBuilder myAction = new StringBuilder("com.yourpackage.");
myAction.append(theClass);
Intent i = new Intent(myAction.toString());
startActivity(i)

The myAction string (in this example com.yourpackage.Login should be specified in the AndroidManifest.xml under an activity

From the doc:

public Intent (String action)

Since: API Level 1 Create an intent with a given action. All other fields (data, type, class) are null. Note that the action must be in a namespace because Intents are used globally in the system -- for example the system VIEW action is android.intent.action.VIEW; an application's custom action would be something like com.google.app.myapp.CUSTOM_ACTION.
