setEnabled() vs setClickable(), what is the difference?
up vote 10 down vote favorite |
Until now, when I wanted to block the user from pressing the button, I would set thebutton.setClickable(false); , and usually change the text to some kind of gray (to let the user know that the button is disabled). today I stumble on the setEnabled() property. So I went to the documentation to see that: setEnabled(boolean enabled)
Set the enabled state of this view.
What the hell is that mean? what is the difference between enable state/clickable state and disabled state/ not clickable state? Some one could please explain what is the difference between doing what I was doing until now (using the clickable property) and using the setEnable property? what should be used when? I search SO but could not find something related. Thanks.

What the hell is that mean?
Quoting the Wikipedia page for "GUI widget": In the context of an application, a widget may be enabled or disabled at a given point in time. An enabled widget has the capacity to respond to events, such as keystrokes or mouse actions. A widget that cannot respond to such events is considered disabled. The appearance of disabled widget is typically different from an enabled widget; the disabled widget may be drawn in a lighter color, or may be visually obscured in some way. See the image to the right for an example.
This concept has been around for a couple of decades and can be found in most GUI frameworks. what is the difference between enable state/clickable state and disabled state/ not clickable state?
In Android, a widget that is not clickable will not respond to click events. A disabled widget not only is not clickable, but it also visually indicates that it is disabled. what do you mean by: "..since it makes the Button visually "disabled"? how does it changes it visually?
What makes a Button look and respond like a Button is its background, which is a StateListDrawable . There is a specific image used for the disabled state.
