请澄清哪个平台!!!
对于浏览器,您必须使用JavaScript onbeforeunload事件和Flash externalInterface。 Here is a how to Link!
对于Android,它看起来像这样!
if(Capabilities.cpuArchitecture=="ARM") // check if Android
{
NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE, handleActivate, false, 0, true);
NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE, handleDeactivate, false, 0, true);
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
}
private function handleActivate(event:Event):void
{
// load your stuff again or whatever
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
}
private function handleDeactivate(event:Event):void
{
// Save your Stuff and do whatever!!!
NativeApplication.nativeApplication.exit();
}
private function handleKeys(event:KeyboardEvent):void
{
if(event.keyCode == Keyboard.BACK){
// Save your Stuff and do whatever!!!
NativeApplication.nativeApplication.exit();
}
}
