StageOrientationEvent 未在 ActionScript 3 中调度

Question

我有来自 adobe 论坛的这段代码，它可以在移动应用程序的第一个屏幕上运行。但如果我将此代码放在新视图中（在我推送的视图中），它就不起作用 有人知道这个问题的解决办法吗？

            }
            private function _onAddedToStage(event:Event):void{
                if(stage.autoOrients)                    stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, _onStage_OrientationChange);
            }

    switch(event.afterOrientation){
                    case StageOrientation.DEFAULT:
                        trace('DEFAULT')
                        break;
                    case StageOrientation.ROTATED_RIGHT:

Answer 1

试试这个：

 protected function view1_creationCompleteHandler(event:FlexEvent):void{

        if(stage.autoOrients)       

        stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, _onStage_OrientationChange);

    }
