Android固定头部sticky-headers RecycleView-白红宇

一个使用LinearLayoutManager为RecyclerViews加上section headers效果的列表控件，支持横向和纵向。

运行效果：

使用说明：

主要有三个类：StickyRecyclerHeadersAdapter, StickyRecyclerHeadersDecoration, 和StickyRecyclerHeadersTouchListener.

StickyRecyclerHeadersAdapter的使用非常接近于 RecyclerView.Adapter，建议让你的 RecyclerView.Adapter实现 StickyRecyclerHeadersAdapter，StickyRecyclerHeadersAdapter接口如下：

                                     
public interface StickyRecyclerHeadersAdapter<VH extends RecyclerView.ViewHolder> { 
  
public long getHeaderId(int position);
  
public VH onCreateHeaderViewHolder(ViewGroup parent);
  
public void onBindHeaderViewHolder(VH holder, int position);
  
public int getItemCount();
}

StickyRecyclerHeadersDecoration是整个效果的关键，但你并不需要额外的配置，下面是在activity中使用它的例子：

                                     
mRecyclerView = (RecyclerView) findViewById(R.id.recyclerview);
mAdapter = 
new
 MyStickyRecyclerHeadersAdapter();
mRecyclerView.setAdapter(mAdapter);
mRecyclerView.setLayoutManager(
new
 LinearLayoutManager(context));
mRecyclerView.addItemDecoration(
new
 StickyRecyclerHeadersDecoration(mAdapter));
            
          

StickyRecyclerHeadersTouchListener是section头部被点击的事件的监听者，使用如下：

                                     
StickyRecyclerHeadersTouchListener touchListener =
    
new
 StickyRecyclerHeadersTouchListener(recyclerView, headersDecor);
touchListener.setOnHeaderClickListener(
    
new
 StickyRecyclerHeadersTouchListener.OnHeaderClickListener() { 
      
@Override
      
public void onHeaderClick(View header, int position, long headerId) { 
        
Toast.makeText(MainActivity.
this
, 
"Header position: "
 + position + 
", id: "
 + headerId,
            
Toast.LENGTH_SHORT).show();
      
}
    
});
mRecyclerView.addOnItemTouchListener(touchListener);
