Unity--实现列表效果(适用于TV遥控器or方向键)--动态规划Button的Navigation
如图
可以再list初始化或者导航有变动的操作后重新分配下各Item的导航。
public void RefreshListItemFocus()
{
for (int i = 0; i < listItem.Count; i++)
{
Navigation na = new Navigation();
na.mode = Navigation.Mode.Explicit;
Button activeBtn = null;
foreach (Button btn in listItem[i].transform.GetComponentsInChildren<Button>())
{
if (btn.enabled && btn.gameObject.activeSelf && (btn.name == "get_button")
{
activeBtn = btn;
break;
}
}
if (i % 2 == 0)//2为 list列数
{
if (activeBtn != null)
{
na.selectOnRight = activeBtn;
}
else
{
if (i + 1 < listItem.Count) na.selectOnRight = listItem[i + 1].GetComponent<Button>();
}
}
else if (i % 2 == 1)
{
if (i - 1 >= 0) na.selectOnLeft = listItem[i - 1].GetComponent<Button>();
if (activeBtn != null)
{
na.selectOnRight = activeBtn;
}
else
{
na.selectOnRight = null
}
}
if (i - 2 >= 0) na.selectOnUp = listItem[i - 2].GetComponent<Button>();
if (i + 2 < listItem.Count) na.selectOnDown = listItem[i + 2].GetComponent<Button>();
listItem[i].GetComponent<Button>().navigation = na;
}
}
