Android使用RecyclerView实现自定义列表、点击事件以及下拉刷新

mLayoutManager = new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false);
recyclerview.setLayoutManager(mLayoutManager);

横向列表：

mLayoutManager = new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false);
recyclerview.setLayoutManager(mLayoutManager);

垂直表格布局：

mLayoutManager = new GridLayoutManager(this,2);
recyclerview.setLayoutManager(mLayoutManager);

水平表格布局：（第四个参数代表是否反转）

mLayoutManager = new GridLayoutManager(this,2,LinearLayoutManager.HORIZONTAL,false);
recyclerview.setLayoutManager(mLayoutManager);

6. 为什么要自己添加OnItemClickListener

RecyclerView有一个缺点，在RecyclerView中，没有一个onItemClickListener方法。所以目前在适配器中处理这样的事件比较好。如果想要从适配器上添加或移除条目，需要明确通知适配器。这与先前的notifyDataSetChanged()方法稍微有些不同。具体操作在适配器代码中就可以体现。

具体代码如下：

public class RecyclerAdapter extends RecyclerView.Adapter {

  private List<Model> models;

  public RecyclerAdapter(List<Model> models){
    this.models = models;
  }

  class ViewHolder extends RecyclerView.ViewHolder{

    private ImageView picture;
    private TextView title,text;

    public ViewHolder(View itemView) {
      super(itemView);

      picture = (ImageView) itemView.findViewById(R.id.picture);
      text = (TextView) itemView.findViewById(R.id.text);
    }

    public ImageView getPicture(){
      return picture;
    }

    public TextView getTitle(){
      return title;
    }

    public TextView getText(){
      return text;
    }
  }

  @Override
  public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    return new ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_view,null));
  }

  @Override
  public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {

    final ViewHolder vh = (ViewHolder) holder;
    vh.getPicture().setImageResource(models.get(position).getPicture());
    vh.getTitle().setText(models.get(position).getTitle());
    vh.getText().setText(models.get(position).getText());

    //如果设置了回调，就设置点击事件
    if (mOnItemClickListener != null){
      vh.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          mOnItemClickListener.onItemClick(vh.itemView,position);
        }
      });
    }
  }

  @Override
  public int getItemCount() {
    return models.size();
  }

  /**
   * ItemClick的回调接口
   */
  public interface OnItemClickListener{
    void onItemClick(View view,int position);
  }

  private OnItemClickListener mOnItemClickListener;

  public void setmOnItemClickListener(OnItemClickListener mOnItemClickListener){
    this.mOnItemClickListener = mOnItemClickListener;
  }
}
