本文介绍了一个使用Android中ObjectAnimator实现的视图动画案例。该案例通过点击事件触发，完成图片沿Y轴移动并伴随缩放效果的动画，动画结束后会启动新的活动SanActivity。动画运用了AnimatorSet来组织动画序列，并设置了监听器来处理动画结束后的跳转逻辑。

public class MainActivity extends AppCompatActivity {

    private ImageView image;
    boolean b=true;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        image = (ImageView) findViewById(R.id.image);
        image.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ObjectAnimator moveIn = ObjectAnimator.ofFloat(image, "translationY", 0f,-500f, -500f);
                ObjectAnimator animator = ObjectAnimator.ofFloat(image, "scaleY",  1f,2f, 1f);//缩放
                AnimatorSet animSet = new AnimatorSet();
                animSet.play(animator).after(moveIn);
                animSet.setDuration(3000);
                animSet.start();
                animator.addListener(new Animator.AnimatorListener() {//监听事件
                    @Override
                    public void onAnimationStart(Animator animation) {

                    }

                    @Override
                    public void onAnimationEnd(Animator animation) {
                        Intent intent = new Intent(MainActivity.this, SanActivity.class);
                        startActivity(intent);
                    }

                    @Override
                    public void onAnimationCancel(Animator animation) {

                    }

                    @Override
                    public void onAnimationRepeat(Animator animation) {

                    }
                });








            }
        });;


    }

}
