android中的AnimationSet问题

Question

我正在使用AnimationSet来执行TranslateAnimations序列.

    icon = (ImageView)findViewById(R.id.icon);

    AnimationSet animationSet = new AnimationSet(true);
    animationSet.setInterpolator(new AccelerateInterpolator());

    TranslateAnimation slide1 = new TranslateAnimation(0, 50, 0, 100); 
    slide1.setStartOffset(0);
    slide1.setDuration(800);
    animationSet.addAnimation(slide1);

    TranslateAnimation slide2 = new TranslateAnimation(50, 100, 100, -100); 
    slide2.setStartOffset(1000);
    slide2.setDuration(800);
    animationSet.addAnimation(slide2);
....

    animationSet.setFillAfter(true);
    icon.startAnimation(animationSet);

我的问题是动画非常生涩.第一个动画突然发生,然后第二个动画开始.我怎样才能让它变得平滑均匀？

Answer 1

创建动画的xml文件并试试这个

            AnimationSet animSet = new AnimationSet(false);
    Animation AnimFirst = AnimationUtils.loadAnimation(act, R.anim.first);
    Animation rAnimSecond = AnimationUtils.loadAnimation(act, R.anim.second);
    animSet.addAnimation(AnimFirst);
    animSet.addAnimation(AnimSecond);
    animSet.setInterpolator(new AccelerateDecelerateInterpolator());
    icon.clearAnimation();
    animSet.setFillAfter(true);
    icon.startAnimation(animSet);

animFirst.xml

       <set xmlns:android="http://schemas.android.com/apk/res/android">
   <translate android:fromYDelta="100%" android:toXDelta="0"
    android:duration="2000" android:fillAfter="true" />
      </set>
