最近項目中用到RadialMenu，效果圖如下所示：(圖片因為公司要求不能掛出來，所以截取中一部分了)
閑下來就對，devexpress中的RedialMenu的使用總結一下。
第一：假設RedialMenu中全部是BarButtonItem的情況。
第二：假設RedialMenu中有BarSubItem也有BarButtonItem的情況。
第三：假設先按首字母進行歸類，首字母全部為BarSubItem,其中的子類為BarButtonItem。
第一中情況的效果圖如下所示
調用代碼：
radialMenu.InitDate(barManager, 9, ItemClick, this); radialMenu.AddSubItemAndItem(list);
其中紅色字體list是初始化數據：
List<string> list = new List<string>(); for (int i = 1; i <= 5; i++) { list.Add("啊受命於天" + i); } for (int i = 1; i <= 6; i++) { list.Add("吧受命於天" + i); } for (int i = 1; i <= 7; i++) { list.Add("才受命於天" + i); } for (int i = 1; i <= 8; i++) { list.Add("的受命於天" + i); } for (int i = 1; i <= 9; i++) { list.Add("額受命於天" + i); } for (int i = 1; i <= 10; i++) { list.Add("飛受命於天" + i); } for (int i = 1; i <= 11; i++) { list.Add("個受命於天" + i); } for (int i = 1; i <= 12; i++) { list.Add("好吧受命於天" + i); } for (int i = 1; i <= 13; i++) { list.Add("就才受命於天" + i); } for (int i = 1; i <= 14; i++) { list.Add("看的受命於天" + i); } for (int i = 1; i <= 15; i++) { list.Add("了額受命於天" + i); } for (int i = 1; i <= 16; i++) { list.Add("嗎飛受命於天" + i); } for (int i = 1; i <= 17; i++) { list.Add("你受命於天" + i); } for (int i = 1; i <= 18; i++) { list.Add("哦吧受命於天" + i); } for (int i = 1; i <= 19; i++) { list.Add("平才受命於天" + i); } for (int i = 1; i <= 20; i++) { list.Add("去的受命於天" + i); } for (int i = 1; i <= 21; i++) { list.Add("人額受命於天" + i); } for (int i = 1; i <= 22; i++) { list.Add("是飛受命於天" + i); } for (int i = 1; i <= 23; i++) { list.Add("他才受命於天" + i); } for (int i = 1; i <= 24; i++) { list.Add("我的受命於天" + i); } for (int i = 1; i <= 25; i++) { list.Add("想受命於天" + i); } for (int i = 1; i <= 26; i++) { list.Add("一飛受命於天" + i); } for (int i = 1; i <= 27; i++) { list.Add("在飛受命於天" + i); }
第二中情況的效果圖如下所示
調用代碼：
List<string> list = new List<string>(); Dictionary<string, List<string>> dic = new Dictionary<string, List<string>>(); for (int i = 0; i < 10; i++) { list.Clear(); for (int j = 0; j <= i + 5; j++) { list.Add("受命於天" + j); } if (i % 5 == 0) list.Clear(); dic["受命於天" + i] = new List<string>(list); } radialMenu.InitDate(barManager, 10, ItemClick, this); radialMenu.AddSubItemAndItem(dic);
第三中情況的效果圖如下所示
按漢子首字母拼英進行歸類，其中的子項歸為首字母中。
調用代碼：
radialMenu.InitDate(barManager, 9, ItemClick, this); radialMenu.AddSubItemAndItem(list);
代碼中的list與第一種情況下的list一樣。
新建RadialMenu的擴展方法InitDate和AddSubItemAndItem。代碼如下所示：
