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); 
  } 
}
