I have 2 activity, called screen1 , screen2 . I use them as fragments (but these are not fragments, but simply an activity), in which there is an ImageButton . screen1 , screen2 I throw in the viewFlipper , which is in activity_main to make Sliding. I did it all, Sliding works, but ... Buttons do not react at all, because there is no handler. I want to make the handlers of these buttons in one main class MainActivity . The question is, how do I get from screen1, screen2 ImageButton and put them handlers in the main class?

So added screen1 and screen2 to the main activity_main , to the ViewFlipper block

 flipper = (ViewFlipper) findViewById(R.id.viewFlipper); LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); int layouts[] = new int[] { R.layout.screen1, R.layout.screen2 }; for (int layout : layouts){ flipper.addView(inflater.inflate(layout, null)); }

  • No need to create a new question with clarification of the old. It was necessary to make the old edit. - Yuriy SPb ♦
  • And you, it seems, are not 3 activations, but one. And the rest is just some kind of markup, which has nothing to do with activization ... The question is still not entirely clear. - YurySPb ♦
  • In theory, you can simply after adding markups to the ViewFlipper through him and look for his insides by their ID - YuriySPb ♦
  • Here you have a MainActivity, an activity_main XML file is attached to it, a container of other XML files (but these are not fragments, but just markup) that are enclosed in the viewFlipper block, which is located in activity_main, so that I can make Sliding . This is all I did. But the buttons that are in screen1 they do not work, because there is no class. I want to use the contents of screen1 in the MAIN CLASS MainActivity. How can I do it? - Edward
  • Do these buttons have your ID? - YurySPb ♦

In the activity you can get a link to any element of its markup by its ID. Even if you added elements manually from another markup.

 //после добавления во ViewFlipper ImageButton btnGoogle = (ImageButton) findViewById(R.id.btnGoogle);

The main thing to remember is that if there is a View with the same ID in the markup, then there is only one of them, which can be fraught with errors.

And for such a task there is a ViewPager with fragments.
