// TODO Auto-generated method stub 
String[] columns = new String[] {EX_RowID,EX_Cattype, EX_Date, EX_Price, EX_Type }; 
Cursor c= ourdatabase.query(Food_TABLE, columns, EX_Date + "= BETWEEN '"+ fd + "' 
AND '" + td + "'" , null, null, null, null);

Answer 1

如果最终转化为SQL正确的语法是：

WHERE SOME_DATE_COLUMN BETWEEN <Date1> AND <Date2> 

所以你的问题（或你的问题之一）似乎在这里。

EX_Date + "= BETWEEN '" 

删除=标志。
