ObjectAnimator 属性动画和组合_objectanimator 组合-优快云博客

本文介绍了一种使用Java在Android中实现视图动画的方法，包括平移、旋转、透明度变化及缩放等基本动画效果，并通过AnimatorSet将这些动画组合起来，实现了流畅的动画过渡效果。

//获取屏幕高
int wallpaperDesiredMinimumHeight = context.getWallpaperDesiredMinimumHeight();
//平移
 ObjectAnimator translationY = ObjectAnimator.ofFloat(view, "translationY", wallpaperDesiredMinimumHeight / 2 - 100);
//旋转
 ObjectAnimator rotation = ObjectAnimator.ofFloat(view, "rotation",0,360);
 //透明
 ObjectAnimator alpha = ObjectAnimator.ofFloat(view, "alpha", 0 ,1);
//缩放
 ObjectAnimator scaleX = ObjectAnimator.ofFloat(view, "scaleX",2,1);
//组合
 AnimatorSet aa=new AnimatorSet();
 //aa.playSequentially(translationY,rotation,alpha,scaleX);
 aa.playTogether(translationY,rotation,alpha,scaleX);
 aa.setDuration(3000);
 aa.start();
 //事件
  aa.addListener(new Animator.AnimatorListener() {
      @Override
      public void onAnimationStart(Animator animator) {

      }

      @Override
      public void onAnimationEnd(Animator animator) {
                     iView.succeed();
      }

      @Override
      public void onAnimationCancel(Animator animator) {

      }

      @Override
      public void onAnimationRepeat(Animator animator) {

      }
  });
