获得XRecyclerView的滑动距离

//XRecyclerView的滑动，，判断向上滑动的距离是否大于600，，true=灰色，，false=透明，，#00000000 shouXRecyclerView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
    @Override
    public void onScrollChange(View view, int i, int i1, int i2, int i3) {
        //获取滑动距离，，通过布局管理器  //1.获得视图的第一条木的下标  //2.根据下标获得view条目,,,在获得条目的高度  //3.下标*条目高度-可见视图距离顶部的高度  LinearLayoutManager layoutManager = (LinearLayoutManager) shouXRecyclerView.getLayoutManager();
        int position = layoutManager.findFirstVisibleItemPosition();
        View firstVisiableChildView = layoutManager.findViewByPosition(position);
        int itemHeight = firstVisiableChildView.getHeight();
        int i4 = (position) * itemHeight - firstVisiableChildView.getTop();
        Log.i("jibbb","==="+i4);
        if(i4>600){
            sousuo.setBackgroundColor(getResources().getColor(R.color.fenleilvbeijing));
        }else{
            sousuo.setBackgroundColor(getResources().getColor(R.color.touming));
        }
    }
});
