HorizontalScrollView实现先左滑动后右滑动动画

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

HorizontalScrollView hsTabs = (HorizontalScrollView ) findViewById(R.id.hsTabs);

new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {

                
                
                ObjectAnimator oa = ObjectAnimator.ofInt(hsTabs, "scrollX", 0, 150);
                oa.setDuration(500);
                

                final ObjectAnimator oa2 = ObjectAnimator
                        .ofInt(hsTabs, "scrollX", 150, 0);
                oa2.setDuration(500);

                oa.addListener(new AnimatorListener() {

                    @Override
                    public void onAnimationStart(Animator arg0) {

                    }

                    @Override
                    public void onAnimationRepeat(Animator arg0) {

                    }

                    @Override
                    public void onAnimationEnd(Animator arg0) {
                        oa2.start();

                    }

                    @Override
                    public void onAnimationCancel(Animator arg0) {

                    }
                });

                oa.start();

            }
        }, 1000);
}
