android – Explanation of state_activated, state_selected, state_pressed, state_focused for ListView

Posted by: admin April 23, 2020 Leave a comment

Questions:

Can anyone explain (or point me to a link that explains) the difference between state_activated, state_selected, state_pressed, and state_focused for ListView items? Are they all valid states for ListViews? Does it matter if touch or a keyboard are being used? This link no longer seems to be valid.

Many thanks!

How to&Answers:
  • state_selected is used when an item is selected using a
    keyboard/dpad/trackball/etc.
  • state_activated is used when View.setActivated(true) is called. This
    is used for “persistent selection” (see Settings on tablet for
    instance)
  • state_pressed is used when the user is pressing the item either
    through touch or a keyboard or a mouse
  • state_focused is used if the item is marked focusable and it receives
    focus either through the user of a keyboard/dpad/trackball/etc. or if
    the item is focusable in touch mode
