示例1: onCreateView

import android.support.v7.widget.PagerSnapHelper; //导入依赖的package包/类
@Override
protected View onCreateView() {
    View root = LayoutInflater.from(getContext()).inflate(R.layout.fragment_pagerlayoutmanager, null);
    ButterKnife.bind(this, root);

    mQDItemDescription = QDDataManager.getInstance().getDescription(this.getClass());
    initTopBar();

    mRecyclerView = new RecyclerView(getContext());
    mPagerLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false);
    mRecyclerView.setLayoutManager(mPagerLayoutManager);
    mRecyclerViewAdapter = new QDRecyclerViewAdapter();
    mRecyclerViewAdapter.setItemCount(10);
    mRecyclerView.setAdapter(mRecyclerViewAdapter);
    mPagerWrap.addView(mRecyclerView);
    // PagerSnapHelper每次只能滚动一个item;用LinearSnapHelper则可以一次滚动多个，并最终保证定位
    // mSnapHelper = new LinearSnapHelper();
    mSnapHelper = new PagerSnapHelper();
    mSnapHelper.attachToRecyclerView(mRecyclerView);
    return root;
}
