Unity实现QQ列表折叠菜单
本文实例为大家分享了Unity实现QQ列表折叠菜单的具体代码,供大家参考,具体内容如下
主要用到了GUI的自动布局功能,VerticalLayoutGroup,注意ChildControlsSize 和ChildForceExpand属性设置为 Width
效果:
实现代码:
/// <summary> /// 折叠菜单 /// </summary> public class FoldPanel : MonoBehaviour { [SerializeField] private GameObject panelItem; // 折叠页 [SerializeField] private TitleItem titleItem; [SerializeField] private DataItem dataItem; public List<FoldData> dataList = new List<FoldData>(); private void Start() { Create(); } public void Create() { for (int i = 0; i < dataList.Count; i++) { // 创建标题 TitleItem title = Instantiate(titleItem).GetComponent<TitleItem>(); title.SetTitle(dataList[i].titleName); title.transform.SetParent(this.transform); // 创建子折叠面板 GameObject panel = Instantiate(panelItem); panel.transform.SetParent(this.transform); // 260是折叠页的宽度,30DataItem的高度 panel.GetComponent<RectTransform>().sizeDelta = new Vector3(260,30 * dataList[i].data.Count); title.SetFoldPanel(panel); panel.SetActive(false); // 创建折叠页数据 for (int j = 0; j < dataList[i].data.Count; j++) { DataItem item = Instantiate(dataItem).GetComponent<DataItem>(); item.transform.SetParent(panel.transform); item.SetInfo(dataList[i].data[j]); } } } } [System.Serializable] public class FoldData { public string titleName; public List<ItemData> data; } [System.Serializable] public class ItemData { public string userName; //public string imageName; public Sprite imageName; }
TitleItem.cs
public class TitleItem : MonoBehaviour,IPointerClickHandler { [SerializeField] private Text title; [SerializeField] private Transform arrow; public bool isFold = true; // 是否是折叠状态 public Transform foldPanel; public void OnPointerClick(PointerEventData eventData) { if (isFold) { isFold = false; arrow.DORotate(Vector3.zero, 0.1f); if (foldPanel != null) { foldPanel.gameObject.SetActive(true); foldPanel.DOScaleY(1, 0.1f); } } else { isFold = true; arrow.DORotate(new Vector3(0, 0, 90), 0.1f); if (foldPanel != null) { foldPanel.DOScaleY(0, 0.1f).OnComplete(() => { foldPanel.gameObject.SetActive(false); }); } } } public void SetTitle(string _titleName) { title.text = _titleName; } public void SetFoldPanel(GameObject panel) { foldPanel = panel.transform; } }
列表的数据来源是在界面上手动配置的,当然如果想要读取本地或者服务器的数据也是可以的。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
