使用

• StickyDecoration——文字悬浮java//回调GroupListener groupListener = new GroupListener() {@Overridepublic String getGroupName(int position) {       //根据position获取对应的组名称       return dataList.get(position).getProvince();}};//创建StickyDecoration，实现悬浮栏StickyDecoration decoration = StickyDecoration.Builder .init(groupListener) .setGroupBackground(Color.parseColor("#48BDFF")) //背景色 .setGroupHeight(DensityUtil.dip2px(this, 35)) //高度 .setGroupTextColor(Color.WHITE) //字体颜色 .setGroupTextSize(DensityUtil.sp2px(this, 15)) //字体大小 .setTextLeftMargin(DensityUtil.dip2px(this, 10)) //左边距 .build();...mRecyclerView.addItemDecoration(decoration);效果：

• PowerfulStickyDecoration——自定义View悬浮

先创建布局item_group```xml

创建`PowerfulStickyDecoration`，实现自定`View`悬浮javaPowerGroupListener listener = new PowerGroupListener() { @Override public String getGroupName(int position) { return dataList.get(position).getProvince(); }

@Overridepublic View getGroupView(int position) {    //获取自定定义的组View    View view = getLayoutInflater().inflate(R.layout.item_group, null, false);    ((TextView) view.findViewById(R.id.tv)).setText(dataList.get(position).getProvince());    return view;}

};PowerfulStickyDecoration decoration = PowerfulStickyDecoration.Builder .init(listener) .setGroupHeight(DensityUtil.dip2px(this, 40)) //设置高度 .build();

...mRecyclerView.addItemDecoration(decoration);```效果：
