集成

方式一：
将项目中的build.gradle文件中dependencies→classpath版本改为对应的版本（即你的IDE新建项目中所用的版本）
添加har到entry下的libs文件夹内
entry的build.gradle内添加如下代码
implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])


方式二：
allprojects{
    repositories{
        mavenCentral()
    }
}
implementation 'io.openharmony.tpc.thirdlib:AnimationEasingFunctions:1.0.2' 

使用示例

  private ListContainer mEasingList;
    private EasingAdapter mAdapter;
    private Component mTarget;
    private long mDuration = 2000;
    private DrawView mHistory;

        mEasingList = (ListContainer) findComponentById(ResourceTable.Id_easing_list);
        mAdapter = new EasingAdapter(this);
        mEasingList.setItemProvider(mAdapter);
        mTarget = findComponentById(ResourceTable.Id_target);
        mHistory = (DrawView) findComponentById(ResourceTable.Id_history);
        mEasingList.setItemClickedListener(new ListContainer.ItemClickedListener() {
            @Override
            public void onItemClicked(ListContainer listContainer, Component component, int position, long var4) {
                mHistory.clear();
                Skill skill = (Skill) component.getTag();
                // 动画集合
                AnimatorGroup set = new AnimatorGroup();
                mTarget.setTranslationX(0);
                mTarget.setTranslationY(0);
                // 数值动画
                AnimatorValue animator = new AnimatorValue();
                animator.setDuration(mDuration);
                BaseEasingMethod easing = skill.getMethod(mDuration);
                // 画最开始的点
                mHistory.drawPoint(0, mDuration, 0 - vpToPixels(getContext(), 60));
                set.runSerially(
                        Glider.glide(skill, mDuration, animator,new AnimatorValue.ValueUpdateListener() {
                    @Override
                    public void onUpdate(AnimatorValue animatorValue, float value) {

                        float start = 0;
                        float end = -vpToPixels(getContext(), 157) ;
                        float result = easing.evaluate(value, start, end);
                        mTarget.setTranslationY(result);
                        mHistory.drawPoint(mDuration * value, mDuration, result - vpToPixels(getContext(), 60));
                    }
                }));
                set.setDuration(mDuration);
                set.start();
            }
        });
