依赖

 compile 'com.github.lvzhihao100:PinHeadForRecyclerView:1.3'

使用方式

PInHeadItemDecoration floatingItemDecoration = new PInHeadItemDecoration();
        recyclerView.addItemDecoration(floatingItemDecoration);
        floatingItemDecoration
                .bgColor(context.getResources().getColor(R.color.hint_bg))//设置头部背景颜色
                .textSize(30 * WindowUtil.csw / WindowUtil.width)//设置画笔字体大小
                .titleHeight(40 * WindowUtil.csw / WindowUtil.width);//设置悬浮头部的高度

自定义悬浮头部,实现DecorationDrawer接口,

floatingItemDecoration.setDecorationDrawer(new DecorationDrawer() {
            //绘制滑动的头部
            @Override
            public void drawVertical(Canvas canvas, String s, float v, float v1, float v2, float v3, Paint paint, Paint paint1, float v4, int i) {

            }
            //绘制悬浮在最上面的头部
            @Override
            public void drawFlow(Canvas canvas, String s, float v, float v1, float v2, float v3, Paint paint, Paint paint1, float v4, int i) {

            }
        });

设置魅族样式悬浮头

        floatingItemDecoration.setDecorationDrawer(new MeizuDecorationDrawer());
