在用Android自带数据库时遇到这个错误：

java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow.  Make sure the Cursor is initialized correctly before accessing data from it

找了半天
原来是数据库里面变量名与Android所写的变量名不一致造成的

这个错误通常是因为查询返回的Cursor中没有指定的列名，你可以检查一下查询语句是否正确，确保查询到的列名与你指定的列名相同。另外，你可以尝试在查询语句中指定需要查询的列和排序方式，例如： ```java String[]...
cursor有一行数据，输入这段代码if(cursor.getCount()>0){ List<Map<String,Object>> mapList=new ArrayList<Map<String,Object>>(); while(cursor.moveToNext()){ Map<String,Object> listitem=new HashMap<String,Object>(); listitem.put("cnumber",cursor.getInt(1)); listitem.put("cname",cursor.getString(2)); listitem.put("cclass",cursor.getString(3)); listitem.put("cteacher",cursor.getString(4)); listitem.put("cterm,",cursor.getString(5)); String cimage=cursor.getString(6); imageView.setImageResource(Integer.parseInt(cimage)); }出现了下面的错误： Caused by: java.lang.IllegalStateException: Couldn't read row 0, col 6 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
