android – WearableRecyclerView .scrollToPosition不适合穿？

我有一组应该在列表中填充的项目,因为我使用了WearableRecyclerView.在某些情况下,我希望特定的项目成为焦点以供选择.我正在使用Wearablelinearlayoutmanager的scrollToPosition()方法,但监视列表不会滚动到所需的位置,但是在使用RecyclerView和scrollLooutManager的scrollToPosition()的手机上也是如此,它设置为RecyclerView工作并滚动到所需位置.

我的佩戴手表代码：

WearableRecyclerView slots_rv = findViewById(R.id.slots_rv);
 .....


        Wearablelinearlayoutmanager wearablelinearlayoutmanager =
            new Wearablelinearlayoutmanager(this,customScrollingLayoutCallback);
    slots_rv.setLayoutManager(
            wearablelinearlayoutmanager);
    slots_rv.setCircularScrollingGestureEnabled(true);
    wearablelinearlayoutmanager.scrollToPosition(slotsAdapter.getPositionToFocus());
    slots_rv.scrollToPosition(slotsAdapter.getPositionToFocus());
    slots_rv.getLayoutManager().scrollToPosition(slotsAdapter.getPositionToFocus());
    slots_rv.setAdapter(slotsAdapter);

这可能会出错？

解决方法

看起来你没有使用你在第二行声明的Wearablelinearlayoutmanager.您正在将LayoutManager设置为新实例,因此调用scrollToPosition将不起作用.请尝试以下方法

Wearablelinearlayoutmanager wearablelinearlayoutmanager = new Wearablelinearlayoutmanager(this,customScrollingLayoutCallback);
    slots_rv.setLayoutManager(wearablelinearlayoutmanager);

    slots_rv.setCircularScrollingGestureEnabled(true);

    wearablelinearlayoutmanager.scrollToPosition(slotsAdapter.getPositionToFocus());
    slots_rv.setAdapter(slotsAdapter);
