android - 我应该使用 RecyclerView.VERTICAL 而不是 LinearLayoutManager.VERTICAL 吗？

Question

运行 ./gradlew lint 向我报告一个令人困惑的错误:

39: Must be one of: RecyclerView.HORIZONTAL, RecyclerView.VERTICAL

在源代码中:

    38 LinearLayoutManager linearLayoutManager = new LinearLayoutManager(rootView.getContext());
    39 linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    40 recyclerView.setLayoutManager(linearLayoutManager);
    41 recyclerView.setAdapter(recyclerAdapter);

有什么理由我应该将第 39 行更改为

linearLayoutManager.setOrientation(RecyclerView.VERTICAL);

Answer 1

使用 LinearLayoutManager.VERTICAL 或 RecyclerView.VERTICAL 没有区别因为在 LinearLayoutManager 中它们是相同的。

public class LinearLayoutManager extends RecyclerView.LayoutManager implements
    ItemTouchHelper.ViewDropHandler, RecyclerView.SmoothScroller.ScrollVectorProvider {

private static final String TAG = "LinearLayoutManager";

static final boolean DEBUG = false;

public static final int HORIZONTAL = RecyclerView.HORIZONTAL;

public static final int VERTICAL = RecyclerView.VERTICAL;

正如您在 LinearLayoutManager 的代码 fragment 中看到的那样。
