android: what is the difference between focused, enabled, pressed, and selected states?

Enabled -> User Interaction possible.

Disabled -> User interaction not possible.

  • if you hover the mouse over a widget, it isfocussed
  • If you make a press-down (half click) on that widget, it ispressed
  • If you press-down and press-up while the mouse is at the same position, it isselected
with touch input you need to take care of pressed and selected states. if the touch-down happens inside a widget and touch up happens outside the widget, it is not considered to be selected.
Focus in Android refers to a mode that's only used for dpad/trackball selection.
