Do you know how to use the accelerometer to set orientation? I want my application to run in Landscape mode and always displayed upright. If the user turns the phone to a portriat view I want to ignore it, but like I said if they keeps turning to landscape again it needs to flip the view so it is upright. Here is what I did and it is not working. First in the MyTest-app.xml file I set. <autoOrients>false</autoOrients> and <aspectRatio>landscape</aspectRatio>
// MyTest.as snippet. I left out the package and imports from this example and removed other stuff not pertinent to the topic.
public class MyTest extends Sprite {
private var _accelerometer:Accelerometer;
private var _field1:TextField = new TextField();
private var _field2:TextField = new TextField();
private var _lastPosition:int;
public function MyTest() {
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.displayState = StageDisplayState.NORMAL;
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
_lastPosition = 1;
// Fields for Debugging
_field1.y = 10;
_field1.width = 200;
addChild(_field1);
_field2.width = 200;
_field2.y = 20;
addChild(_field2);
stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, onOrientationChange);
if (Accelerometer.isSupported) {
_accelerometer = new Accelerometer();
_accelerometer.setRequestedUpdateInterval(1000); // Check once a second
_accelerometer.addEventListener(AccelerometerEvent.UPDATE, _accelerometer_Update);
}
}
protected function _accelerometer_Update(event:AccelerometerEvent):void {
var y:int = Math.round(event.accelerationY);
_field1.text = "Position " + y;
if (y != _lastPosition && y != 0){
var before:String = (_lastPosition == 1) ? StageOrientation.ROTATED_LEFT : StageOrientation.ROTATED_RIGHT;
var after:String = (y == 1) ? StageOrientation.ROTATED_LEFT : StageOrientation.ROTATED_RIGHT;
_lastPosition = y;
dispatchEvent(new StageOrientationEvent(StageOrientationEvent.ORIENTATION_CHANGE, true, false, before, after));
}
}
protected function onOrientationChange(event:StageOrientationEvent):void
{
_field2.text = event.beforeOrientation + " " + event.afterOrientation;
stage.setOrientation(event.afterOrientation);
}
}
When I run this code the _field1 shows the proper value from the accelerometer depending on how I have the phone oriented. The _field2 even shows the correct events being handled, but the display doesn't flip upright. I look at it upside down when I flip the phone. I also wasn't sure if I should use StageOrientation.DEFAULT and UPSIDE_DOWN, but when I did that I somehow got the phone in portrait mode... and then could not get it to move.
I am using a Motorola Droid with Air 2.7.0.1948 and Android version 2.2.2 and used Flash Builder 4.5 to create everything.
