public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {

        void onItemClick(View view, int position);

        void onItemLongClick(View view, int position);

            @Override

    }
    @Override

        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        }

        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
    }
}

使用：

mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener(this, mRecyclerView, new RecyclerItemClickListener.OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {   /**recyclerView每个item的点击事件*/
                if (isState && position < mPresent.items.size()) {
                    CheckBox checkBox = (CheckBox) view.findViewById(R.id.adapter_interest_course_check_box);
                    if (checkBox.isChecked()) {
                        checkBox.setChecked(false);
                        mPresent.selectItems.set(position, false);
                    } else {
                        checkBox.setChecked(true);
                        mPresent.selectItems.set(position, true);
                    }
                    mAdapter.notifyDataSetChanged();
                    Log.e("onItemClick","点击事件");
                }else{
                    Log.e("onItemClick","点击进入");
                }
            }

            @Override
            public void onItemLongClick(View view, int position) {   /**recyclerView每个item的长按事件*/

                if (!isState) {
                    mPresent.selectItems.clear();
                    for (int i = 0; i < mPresent.items.size(); i++) {
                        mPresent.selectItems.add(false);
                    }
                    setState(true);
                    mAdapter.setIsState(true);
                    Log.e("onItemLongClick","onItemLongClick");
                }else{
                    Log.e("onItemLongClick","长按事件");
                }
            }
        }));
