Andengine onAreaTouched TouchEvent不起作用-ACTION_OUTSIDE和ACTION_CANCEL

Question

I have a simple problem. I have a button on the screen. I want isActionDown to push the button down, and isActionUp to push the button back up again and make my character jump. But the problem is if I push the button down and drag away from it, the button stays pushed down. I would like the button to push back up again if the user drags away from it.

How can I create the desired affect? isActionCancel doesn't seem to do the trick.

    private void addButton(){
    goB = new AnimatedSprite(240, 364, ResourceManager.getInstance().go_region, vbom){
        @Override
        public boolean onAreaTouched(final TouchEvent event, final float x, final float y){


            if (event.isActionDown()){
                goB.animate(new long[]{ 250 }, new int[] { 1 }, true);
                /*if(event.isActionCancel()){
                    goB.animate(new long[]{ 250 }, new int[] { 0 }, true);
                }*/
            }
            if (event.isActionUp()){
                goB.animate(new long[]{ 250 }, new int[] { 0 }, true);
                fresh = true;
                playerBody.applyLinearImpulse(new Vector2(0, 45), playerBody.getPosition());
            }


            if (event.isActionCancel() || event.isActionOutside()){
                goB.animate(new long[]{ 250 }, new int[] { 0 }, true);
            }
            return true;
        }
    };
    goB.setScale(3);

    registerTouchArea(goB);
    attachChild(goB);

    goB.animate(250);
}

I'm having the hardest time with this, and I've tried all sorts of variations of the code above. Please let me know if you have the solution.

Thanks for your help!

Use the

setTouchAreaBindingOnActionDownEnabled(true);
setTouchAreaBindingOnActionMoveEnabled(true);

functions
