设置触发刷新的位置

我觉得出发刷新的位置应该与头部关联更为紧密所以,方法放到AUtils类中setHeaderHeightToRefresh方法,为了不让ZRefreshLayout中方法暴露出去

For exmaple:

    @Override
    public View getView(ZRefreshLayout zRefreshLayout) {
        rootView = View.inflate(zRefreshLayout.getContext(), R.layout.header_meterial, null);
        AUtils.setHeaderHeightToRefresh(zRefreshLayout,(int) (screenPixs[1] * 0.2*0.8));
        ...
        return rootView;
    }

滚动延迟与拦截

interceptAnimateBack方法如果返回true,滚动就会被拦截不执行。

通过AUtils.smoothScrollTo_NotIntercept(iScroll,0);方法让其滚动到特定位置.Tips:此方法不会被拦截!

    mHeaderWaveCircle.setOnViewAniDone(new AnimationView.OnViewAniDone() {
            @Override
            public void viewAniDone() {
                AUtils.smoothScrollTo_NotIntercept(iScroll,0);
            }
        });

   public boolean interceptAnimateBack(AnimateBack animateBack, ZRefreshLayout.IScroll iScroll) {
        this.iScroll = iScroll;
        boolean result = false;
        if (mAnimateBack != animateBack && animateBack == AnimateBack.Complete_Back) {
            //完成时候的滚动返回被拦截
            mHeaderWaveCircle.setRefreshing(false);
            result = true;
        }
        mAnimateBack = animateBack;
        return result;
    }
