android recyclerview准确地滚动到项目的开头

Question

滚动时如何让recyclerview在每个项目的精确开头滚动，例如google play中的水平回收视图。

Answer 1

如果你想实现google play app线性捕捉功能，你可以参考这个教程RecyclerView Snapping

它详细解释了实施它

Answer 2

    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getContext());
    linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
    rvPreview.setLayoutManager(linearLayoutManager);
    rvPreview.setItemAnimator(new DefaultItemAnimator());

并使用此

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