如何在 Android 中创建 rtl GridLayoutManager？

Question

我正在 android 项目中创建一个 recyclerView，我想在我的 recyclerView 中设置一个 gridLayout manager。

这是我的代码：

workHourRecycler = view.findViewById(R.id.market_hours_recycler);
workHourRecycler.setLayoutManager(new GridLayoutManager(getContext(),4));

但是 GridLayout 必须是 'rtl direction' 谁知道？

谢谢。

Answer 1

试试这个

GridLayoutManager layoutManager = new GridLayoutManager(this, numberOfRows, GridLayoutManager.HORIZONTAL, true);

Answer 2

GridLayoutManager gridLayoutManager = new GridLayoutManager(context, 2);
rvProductlist.setLayoutManager(mLayoutManager);

Answer 3

/**
 * @param context Current context, will be used to access resources.
 * @param spanCount The number of columns or rows in the grid
 * @param orientation Layout orientation. Should be {@link #HORIZONTAL} or {@link
 *                      #VERTICAL}.
 * @param reverseLayout When set to true, layouts from end to start.
 */ 



RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(getActivity(), 4, GridLayoutManager.HORIZONTAL, true);
rv_days.setLayoutManager(mLayoutManager);
rv_days.setItemAnimator(new DefaultItemAnimator());

Answer 4

您需要以编程方式更改 RecycleView

的布局方向

workHourRecycler = view.findViewById(R.id.market_hours_recycler);
workHourRecycler.setLayoutManager(new GridLayoutManager(getContext(),4));

//Programtically set the direction
workHourRecycler.setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
