一：Toogle

变形  group

public class RToogleGroup01 : MonoBehaviour {public Toggle tg1;public Toggle tg2;// Use this for initializationvoid Start () {tg1.onValueChanged.AddListener(isOn => {if (isOn){Debug.Log("tg1打开");}else{Debug.Log("tg1关闭");}});tg2.onValueChanged.AddListener(isOn =>{if (isOn){Debug.Log("tg2打开");}else{Debug.Log("tg2关闭");}});}// Update is called once per framevoid Update () {}

public class RToogleGroup02 : MonoBehaviour {public Toggle tg1;public Toggle tg2;public Toggle tg3;public Transform []bgs;// Use this for initializationvoid Start(){tg1.onValueChanged.AddListener(isOn => { ShowBG(0); });tg2.onValueChanged.AddListener(isOn => { ShowBG(1); });tg3.onValueChanged.AddListener(isOn => { ShowBG(2); });}private void ShowBG(int index){for (int i = 0; i < bgs.Length; i++){if (i == index){bgs[i].gameObject.SetActive(true);}else{bgs[i].gameObject.SetActive(false);}}}

二:DropDown

public class RDropdown : MonoBehaviour {Dropdown dropdown;List<string> tempNames;void Awake(){dropdown = GetComponent<Dropdown>();tempNames = new List<string>();dropdown.onValueChanged.AddListener(ExecuteItem);}private void ExecuteItem(int arg0){Debug.Log("执行逻辑："+ arg0);}void Start(){AddNames();UpdateDropdownView(tempNames);}/// <summary>/// 刷数据/// </summary>/// <param name="showNames"></param>private void UpdateDropdownView(List<string> showNames){dropdown.options.Clear();Dropdown.OptionData tempData;for (int i = 0; i < showNames.Count; i++){tempData = new Dropdown.OptionData();tempData.text = showNames[i];dropdown.options.Add(tempData);}dropdown.captionText.text = showNames[0];}private void AddNames(){string s1 = "0";string s2 = "1";string s3 = "2";string s4 = "3";string s5 = "4";tempNames.Add(s1);tempNames.Add(s2);tempNames.Add(s3);tempNames.Add(s4);tempNames.Add(s5);}
}
