Is it possible to create activit once and when you press the button on the main activit the second activit just show, and not create anew?

  • It seems like no, but I think everything is possible with crutches) - Evgeny Suetin
  • I make a small dictionary. And I have a menu and in it the item "Add word" by clicking on it opens a new activation. And if this second activation is already open and I click again in the "Add word" menu, then the activation is created again and I have created the activation several times. And you can do this: If we allow in the second activation, then the menu item "Add word" to make inactive? - user215435
  • What if you hide your list and show the form of adding, in order to avoid the discovery of new activations - Evgeny Suetin
  • You mean that this menu item is not displayed in the second activation? And such a question. I'm new to android, I understand correctly that if you press the back key, then the activation closes? or how to say is destroyed? - user215435
  • yes, she will be called onDestroy () - Eugene Suetin
