RecycleView的多布局以及滑动到某一距离来做显示隐藏某些

鹅鹅鹅曲项向天歌呀
公司最近有一新需求,效果如下图.
演示图.gif
思前想后,想了两种种办法去做.
第一种是recycleView的多布局
第二种用scrollview嵌套tablayout+viewpager+fragment.
显然,第二种要显得麻烦一些,我也懒得去试验,直接采用第一种.
这是一个有帮助的文章链接
分析一下布局
第一分部

分析数据
一共有两个接口
第一部分是一个接口,返回各种字段需要展示的字段
第二部分第三部分是一个接口,返回一个字段＋一个集合
我们要把两个接口的数据塞到一个集合里面,所以,我们定义一个泛型为Serializable的集合
var mList = arrayListOf<Serializable>()这样就可以吧各种数据塞进去了,注意,bean要实现Serializable.
我使用kotlin写的,Object泛型报错,我不晓得为啥,为了完成工作 任务,还米有研究.
好啦,接下来就请求数据,去adapter里面去展示了呗
各小部分布局文件就不展示了哦,我把最外层布局写出来~~~
布局:
封装了一下recycleView,自带刷新和加载更多的功能,普通的也可以哈
我是将悬浮导航栏隐藏了,当滑动与recycleView中的导航栏重合的时候展示出来,否则则隐藏.

最重要的是adapter,要展示不同的布局,加载不同的数据
上代码
class AgentHomeAdapter(context: Context, list: ArrayList<Serializable>) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {
var context: Context
var list: List<Serializable>
var inflater: LayoutInflater
var headerHolder: HeaderHolder? = null
init {
this.context = context
this.list = list
this.inflater = LayoutInflater.from(context)
}
/**
*我是根据位置来加载不同的布局
*第0个位置,ItemViewType为1
*第1个位置,ItemViewType为2
*其他位置均为3,因为都是普通的列表啦
*/
override fun getItemViewType(position: Int): Int {
return if (position == 0) {
1
} else if (position == 1) {
2
} else {
3
}
}
override fun getItemCount(): Int {
LogUtils.e("长度:" + list.size)
return list.size
}
/**
*根据不同ItemViewType来加载不同的布局
*1为第一部分
*2为第二部分
*3为第三部分,也就是普通的列表
*/
override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int): RecyclerView.ViewHolder {
return if (viewType == 1) {
headerHolder = HeaderHolder(inflater.inflate(R.layout.agent_top_layout, parent, false))
headerHolder!!
} else if (viewType == 2) {
MiddleHolder(inflater.inflate(R.layout.agent_middle_layout, parent, false))
} else {
AgentHolder(inflater.inflate(R.layout.activity_my_order_info_item, parent, false))
}
}
/**
*根据不同ItemViewType,讲bean强转成不同的数据,然后直接设置到布局里就完事了
*/
override fun onBindViewHolder(holder: RecyclerView.ViewHolder?, position: Int) {
var bean = list.get(position)
var itemViewType = getItemViewType(position)
if (itemViewType == 1) {
if (bean is AgentBean.DataBean.ContentBean) {
}
}
if (itemViewType == 2) {
if (holder is MiddleHolder) {
(context as AgencyActivity).rb_1 = holder.rb_one
(context as AgencyActivity).rb_2 = holder.rb_two
(context as AgencyActivity).rb_3 = holder.rb_three
(context as AgencyActivity).rb_4 = holder.rb_four
}
}
if (itemViewType == 3) {
if (bean is MyOrderInfoBean.DataBean.ContentBean.ProxyOrdersDataBean) {
if (holder is AgentHolder) {
}
}
}
}
class HeaderHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var agentMoney: TextView
.......
init {
agentMoney = itemView.findViewById(R.id.agentMoney)
.......
}
}
class MiddleHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var tv_account: TextView
......
init {
tv_account = itemView.findViewById(R.id.tv_account)
......
}
}
class AgentHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var tv_status: TextView
.......
init {
tv_status = itemView.findViewById(R.id.tv_status)
......
}
}
}

我的语言组织能力有限,目前只能做成这样了.不明白的可以联系我 QQ1032528317
