我从mySQL数据库获取足球队阵容数据。
我希望将守门员,后卫,中场球员作为每一行的标题显示回收者的球员数据。
我该怎么办?:
1 - 创建3个recyclerview?
2 - 创建3个自定义布局?
3种不同的观看者?
我做的是这个:
我想做的是: 同样的事情,但他们的球员和中场球员与他们的球员显示其他数据作为防守者
这是我的自定义布局(recycler_lineup):

您可以使用标准的RecyclerView方式并定义多种视图类型。您需要在适配器中覆盖函数getItemViewType。此函数需要返回int,用于定义应为元素显示的类型。之后你只需在onCreateViewHolder中处理它。
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if(viewType == TYPE1){
//here you prepare ViewHolder for first view type
return new ViewHolder1();
}else if(viewType == TYPE2){
//here you prepare ViewHolder for another view type
return new ViewHolder2();
}
}
