#### 使用说明


```
      //根据数据类型自定义SectionProvider, 并实现getSectionImpl()方法, 返回Section对象。
      DataSelectionProvider sectionProvider = new DataSelectionProvider(dataList);
      //默认的SectionPainter, 可实现SectionPainter接口进行自定义效果绘制
      TextSectionPainter sectionPainter = new TextSectionPainter.Builder(this)
              .setSectionBarColor(0xffffacac)
              .setDividerColor(0xffff8888)
              .setTextColor(0xffffffff)
              .setTextSize(dip2px(16))
              .setSectionBarHeight(dip2px(32))
              .setDividerHeight(1)
              .build();
      //创建ItemDecoration
      SectionItemDecoration decoration = new SectionItemDecoration(sectionProvider, sectionPainter);

      recyclerView.setLayoutManager(new LinearLayoutManager(this));
      recyclerView.addItemDecoration(decoration);
      recyclerView.setAdapter(new Adapter(dataList));
