Hello, Obviously, I'm hitting a bug but it's different from what I was thinking. If Google folks could comment, it would be great.
I'm trying to operate Ice Cream Sandwich with a keyboard only: no touch, no mouse. In the settings application, I can't turn on/off Wi-Fi with the "Switch Widget" (I wrongly name it toggle in my previous post) by using only a keyboard. The switch widget is handled here: frameworks/base/core/java/android/widget/Switch.java After further investigations (while I was playing around with the "Data usage" pan which has another switch widget), I figured out that if you press enter on a switch widget which has the focus, it does toggle. Great! But I still can't toggle the Wi-Fi switch widget with the "Enter" key in the left bar of the Settings App. I figured out that when I press "enter" while selecting the "Wi-Fi" row, the "enter" event is captured by the row itself and the switch widget actually never gets the focus. This is my problem and this is a bug. So now, I'm back to packages/apps/Settings trying to figure out why a row, which is actually a "header item in PreferenceActivity", doesn't behave the right way. The situation is tricky because a header can be selected or highlighted. But when you have a touch or mouse, highlighting means selecting. And obviously, you don't want to toggle the switch if you highlight=select the header with your finger. I still think that the insufficient keyboard behavior is still fixable without altering the mouse/touch behavior which currently makes sense. Right now, the behavior is "If an enter key is pressed, a highlighted header becomes selected". The behavior to add is: "if a header is selected and highlighted header = selected header and the enter key is pressed, pass the event to the switch", Grégoire PS: BTW, there is a second bug. In the Data usage pan, if you toggle the on/off switch and you reply cancel to "Disable mobile data?" pop-up question, the toggle goes from on to off even if you cancel the request.
