异常: Android.Database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 10
此错误是数据返回到ICursor无法确定获取列的索引,那么需要加上一下代码即可。
if (i == 0) //确定游标位置 { ic.MoveToFirst(); } else { ic.MoveToNext(); }
完整代码Demo:
/// <summary> /// 查询数据 /// </summary> void QueryData() { ICursor ic = Localhost_DataBase.Query("tb_person", null, null, null, null, null, null); for (int i = 0; i < ic.Count; i++) { if (i == 0) //确定游标位置 { ic.MoveToFirst(); } else { ic.MoveToNext(); } person = new Person(); person.Id = ic.GetString(ic.GetColumnIndex("Id")); person.Name = ic.GetString(ic.GetColumnIndex("name")); person.Age = ic.GetString(ic.GetColumnIndex("age")); person.Sex= ic.GetString(ic.GetColumnIndex("sex")); person.IdCard = ic.GetString(ic.GetColumnIndex("idcard")); list.Add(person); } lv_Person.Adapter = new ListViewAdapter(this, list); }
