Android 水平循环视图，当前项目已缩放，下一个项目显示一点

我正在尝试制作一个水平的回收视图，如图中的，左边的截图

我设法做了水平部分，但下一张和预览卡没有显示

这是xml回收视图

<android.support.v7.widget.RecyclerView

    </LinearLayout>
</LinearLayout>

    rv_cards = (RecyclerView) findViewById(R.id.rv_cards);
    rv_cards.setHasFixedSize(true);
    rv_cards.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));

    SnapHelper snapHelper = new LinearSnapHelper();
    snapHelper.attachToRecyclerView(rv_cards);
