리사이클러뷰 아이템 클릭 이벤트

리사이클러뷰는 리스트뷰와는 다르게 엑티비티에서  아이템 클릭 이벤트 처리가 어렵다  그래서 클릭 이벤트를 처리해줄 클래스를 만들어서 처리한다.

 

 

< 클래스 생성 >

package com.team.project.wat_show.main_activity;

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

public class video_content_itemClickListener implements RecyclerView.OnItemTouchListener{

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

    private OnItemClickListener mListener;
    private GestureDetector mGestureDetector;

    public video_content_itemClickListener(Context context,final RecyclerView rView,OnItemClickListener clickListener){

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

            @Override
            public void onLongPress(MotionEvent e)
            {
                View childView = rView.findChildViewUnder(e.getX(), e.getY());

                if(childView != null && mListener != null)
                {
                    mListener.onItemLongClick(childView, rView.getChildPosition(childView));
                }
            }
        });
    }



    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        View childView = rv.findChildViewUnder(e.getX(), e.getY());

        if(childView != null && mListener != null && mGestureDetector.onTouchEvent(e))
        {
            mListener.onItemClick(childView, rv.getChildPosition(childView));
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

 

<< 클릭 리스너를 사용할 곳 >>

// 아이템 클릭 이벤트
public void ItemClick(){
    videoContent_RecyclerView.addOnItemTouchListener(new video_content_itemClickListener(getActivity(),videoContent_RecyclerView,
            new video_content_itemClickListener.OnItemClickListener() {
                @Override
                public void onItemClick(View view, int position) {
                   // Toast.makeText(getContext(), ""+position, Toast.LENGTH_SHORT).show();

                                   }

                @Override
                public void onItemLongClick(View view, int position) {

                }
            }));
}
