我的Activity里有一个ListView,然后再onCreate()方法中添加了如下代码,希望能测试一下LayoutAnimationController,但跑出来没有达到预定的效果,请问这里有什么问题吗?
AnimationSet animationSet = new AnimationSet(true);
AlphaAnimation alphaAnimation = new AlphaAnimation(0.0f, 1.0f);
alphaAnimation.setDuration(500);
animationSet.addAnimation(alphaAnimation);
TranslateAnimation translateAnimation = new TranslateAnimation(
Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, -1.0f,
Animation.RELATIVE_TO_SELF, 0.0f);
translateAnimation.setDuration(500);
animationSet.addAnimation(translateAnimation);
LayoutAnimationController controller = new LayoutAnimationController(animationSet, 0.5f);
controller.setOrder(LayoutAnimationController.ORDER_NORMAL);
mListView.setLayoutAnimation(controller);
