Unity中button 和toggle监听事件函数有无参数

天人合一peng2026-02-01 17:32

1如果调用监听调用的函数没有参数则用

cs 复制代码

            allselect.onClick.RemoveAllListeners();
            allselect.onClick.AddListener(OnAllProInButtonClick);

2 如果需要传参数进去则要用lamude表达式

cs 复制代码

            allselect.onClick.RemoveAllListeners();
            allselect.onClick.AddListener(() =>OnAllProInButtonClick(Select_Info));

            unallselect.onClick.RemoveAllListeners();
            unallselect.onClick.AddListener(() => OnUnAllProInButtonClick(Select_Info));

            RefreshButton.onClick.RemoveAllListeners();
            RefreshButton.onClick.AddListener(() => OnClickRefreshButtonForTaskprocess(task.TaskId));

3 调用函数时两者不现

Toggle

cs 复制代码

 Toggle Select_Info = processmanagerPrefab.transform.Find("Information/Select").GetComponent<Toggle>();

Select_Info.onValueChanged.RemoveAllListeners();
Select_Info.onValueChanged.AddListener(TurnSelectALLNot);

TurnSelectALLNot函数可以无参数的或默认参数为Toggle.isOn的状态的

cs 复制代码

    private void TurnSelectALLNot(bool isOn )
    {

        foreach (var toggle in proToggles.Values)
        {
            if (toggle != null)
            {
                if (isOn)
                {
                    toggle.isOn = true;
                }
                else
                {
                    toggle.isOn = false;
                }
            }
        }

}

Button

cs 复制代码

            Button allselect = processmanagerPrefab.transform.Find("TaskDetailButtons/Button_Select").GetComponent<Button>();

            allselect.onClick.RemoveAllListeners();
            allselect.onClick.AddListener(() =>OnAllProInButtonClick(Select_Info));

思考是不是可以类似toggle有默认参数bool isOn但不用在函数中写的情况呢？
