Android 中RecycleView实现item的点击事件

public class GridViewHolder extends RecyclerView.ViewHolder implements OnClickListener{    //声明MyItemClickListener  private MyItemClickListener mListener;   public GridViewHolder(View rootView,MyItemClickListener listener) {    super(rootView);    this.mListener = listener;     rootView.setOnClickListener(this);      }  @Override  public void onClick(View v) {//如果mListener不为空，就实现接口中的方法onItemClick其中getPosition()是得到被点击位置的position     if(mListener != null){         mListener.onItemClick(v,getPosition());       }   }   //声明MyItemClickListener这个接口    public interface MyItemClickListener {     public void onItemClick(View view,int postion);   } }
