Answer 1

You define your window in XML, say mycoolwindow.xml.

Then from some other part of your code:

 var win=Alloy.createController('mycoolwindow').getView();
 win.open();

See example here: https://github.com/ricardoalcocer/AlloyOpenWindow

Answer 2

Place this function in Window2.js:

function openWindow3(){
Alloy.createController('Window3');
$.Window2.close();
}

window3.js:

$.Window3.open();

First if all closing a window and opening a new window simultaneously doesn't works in Android. The app crashes. Rather what I would suggest is remove all childrens of the window and hide it (For Android Only), for IOS you can close it. This way the memory leaks would also be managed.

About open a window avoid initializing new objects as they occupies memory. Directly use the open function . For eg :

Alloy.createController('mycoolwindow').getView().open();
