recyclerView item Click Listener

现在很多地方提倡用recyclerView来代替listview，因为
recyclerView的很多特性是很方便的，而且更美观简洁。
但是在它里面却没有listview的itemlistener,所以，要自己
去创建一个RecyclerItemClickListener,方法实现如下：

import android.content.Context;  
import android.support.v7.widget.RecyclerView;  
import android.view.GestureDetector;  
import android.view.MotionEvent;  
import android.view.View; 

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {

   private OnItemClickListener mListener;

   public interface OnItemClickListener {
       public void onItemClick(View view, int position);
   }

   GestureDetector mGestureDetector;

   public RecyclerItemClickListener(Context context, OnItemClickListener listener) {
   mListener = listener;
   mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
       @Override
       public boolean onSingleTapUp(MotionEvent e) {
           return true;
       }
     });
   }

   @Override
   public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
       View childView = view.findChildViewUnder(e.getX(), e.getY());
       if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
           mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
       }
       return false;
   }

}

实现了RecyclerView.OnItemTouchListener接口。
当想要调用的时候，需要这样利用：

recyclerView.addOnItemTouchListener(
     new RecyclerItemClickListener (context, new RecyclerItemClickListener.OnItemClickListener() {
          @Override 
          public void onItemClick(View view, int position) {
          //TODO your shings
          }
     })

);

这样就可以实现应用，recyclerView和card一块使用，把card作为item，
这样是很好的。
