为 RecyclerView 添加头部视图

Use

    allprojects {
            repositories {
                ...
                maven { url "https://jitpack.io" }
            }
        }

    dependencies {
                compile 'com.github.eicky:HeaderRecyclerViewAdapter:1.0'
        }

Code

• 创建一个 RecyclerView 的适配器，实现里面的方法

  public class MyAdapter extends HeaderRecyclerViewAdapter<HeaderViewHolder, ItemViewHolder> {
    public MyAdapter(RecyclerView.LayoutManager layoutManager) {
        super(layoutManager);
    }
  
    @Override
    protected int getHeaderCount() {
        //Header 个数
        return 0;
    }
  
    @Override
    protected int getItemCountForSection(int section) {
        //对应 Header 的 Item 个数
        return 0;
    }
  
    @Override
    protected HeaderViewHolder onCreateHeaderViewHolder(ViewGroup parent, int viewType) {
        return null;
    }
  
    @Override
    protected ItemViewHolder onCreateItemViewHolder(ViewGroup parent, int viewType) {
        return null;
    }
  
    @Override
    protected void onBindHeaderViewHolder(HeaderViewHolder holder, int headerPosition) {
  
    }
  
    @Override
    protected void onBindItemViewHolder(ItemViewHolder holder, int headerPosition, int itemPosition) {
  
    }
  }
  

• 在 List 中使用

  LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
  MyAdapter myAdapter = new MyAdapter(linearLayoutManager);
  recyclerview.setAdapter(myAdapter);
  

• 在 Grid 中使用

  GridLayoutManager gridLayoutManager = new GridLayoutManager(Context, 2);
  MyAdapter myAdapter = new MyAdapter(gridLayoutManager);
  recyclerview.setAdapter(myAdapter);
