在水平滚动视图中平滑滚动的问题

Question

我在HorizontalScrollView内有一个 ChipGroup ，该位置设置为在单击 Chip 时可以平滑滚动到某个位置。它们连接到ViewPager，所以当我单击 Chip 时，它会滑动到ViewPager中的片段，而当我滑动ViewPager时，它会检查相应的芯片。

问题是，当我滑动ViewPager的芯片进行检查并确定自己的定位方式时，但是当我单击 Chip 时，它会快速它的位置。

这是滑动时的样子：

这是单击时的样子：

我的代码：

    private Chip chip_plantowatch;

    private HorizontalScrollView scrollView;
    private ChipGroup chipGroup;
    private ViewPager viewPager;

    private int widthScreen;

        View view = inflater.inflate(R.layout.fragment_library, container, false);
        return view;
    }

    @Override

        widthScreen = displayMetrics.widthPixels;

                scrollView.smoothScrollBy(rr.right - (widthScreen - r.right), 0);
            }

            if (chip_watching.isChecked()) {
                Rect rr = new Rect();
                view.getDrawingRect(rr);

                Rect rr = new Rect();
                view.getDrawingRect(rr);
                scrollView.smoothScrollTo(chip_completed.getLeft() - (widthScreen / 2) + (chip_completed.getWidth() / 2), 0);
            }

            if (chip_onhold.isChecked()) {
                Rect rr = new Rect();
                view.getDrawingRect(rr);
                scrollView.smoothScrollTo(chip_onhold.getLeft() - (widthScreen / 2) + (chip_onhold.getWidth() / 2), 0);
            }

            if (chip_dropped.isChecked()) {
                Rect rr = new Rect();
                view.getDrawingRect(rr);
                scrollView.smoothScrollBy(r.right, 0);
            }

            if (chip_plantowatch.isChecked()) {
                Rect rr = new Rect();
                view.getDrawingRect(rr);
                scrollView.smoothScrollBy(r.right, 0);
            }
        }
    };

我尝试将.performClick()替换为.setChecked()并添加.smoothScroolTo()，但是它仍然无法对齐HorizontalScrollView，而不是平滑滚动。

我正在尝试基本理解这一点，同时仍然能够滚动ViewPager：
