How to create a single pop up layout with textbox that can be called anywhere on the app. See below pseudo codes of what I mean;
PopUpClass popup;
private static Singleton instance = null;
class Singleton {
if(instance == null) {
instance = new Singleton ();
// Instantiate a class pop up class layout
popup = new PopUpClass(); // I dont know how to create this one
}
return instance;
}
SomeClass {
private buttonClicked {
Singleton singleton = new Singleton();
PopUpClass popup = singleton.popup;
//add the pop up class to current view
}
}
This means that I want the pop up class created only once so that whatever text on the layout that done on someclass it can also be show on other class.
