【问题描述】：
我编写了一个程序来插入一些数据，其中还包括一个名为日期的列，所以当我插入一些东西时，日期也会同时插入。
插入工作完美，现在在不同的活动中，我有两个来自日期和今天的编辑文本，单击时将打开单独的日期选择器，并且所选日期将设置在相应的编辑文本上，现在我要做的是完成后从日期和日期中选择，我希望我的微调器根据我插入数据的日期来填充。
我尝试了一些不起作用的方法。
这是我创建的表
private static final String CREATE_TABLE_FINALDATA = "Create table
"+TABLE_NAME_FINALDATA+" (" +UID
+" INTEGER PRIMARY KEY, "+REFERENCE_NO+" VARCHAR(200),
"+ACCOUNT_NAME+" VARCHAR(200), "+ACCOUNT_TYPE+" VARCHAR(100)
,"+VEHICLE_NO+" VARCHAR(100), "+DRIVER_CODE+" VARCHAR(50),
"+DRIVER_NAME+" VARCHAR(200), "+DIESEL_TYPE+" VARCHAR(50),
"+DIESEL_RATE+" DOUBLE, "+DIESEL_QUANTITY+" DOUBLE, "+AMOUNT
+" DOUBLE, "+EFFECTIVE_DATE+" VARCHAR(255), "+NO_OF_COPIES
+" VARCHAR(10), "+TIME+" VARCHAR(255), "+TRANSACTION_ID+"
VARCHAR(500), "+REMARK+" VARCHAR(500), "+SYNC+" VARCHAR(20),
"+CLIENT_CODE+" VARCHAR(255))";
private static final String DROP_TABLE_FINALDATA = "Drop table If Exists
"+TABLE_NAME_FINALDATA;
这是根据日期获取 accountname 值的查询
public Cursor getAccName(String fromdate, String todate) {
SQLiteDatabase db = helper.getWritableDatabase();
Cursor cursor = db.rawQuery("Select
"+DbListHelper.ACCOUNT_NAME+", "+DbListHelper.UID+
" from " + DbListHelper.TABLE_NAME_FINALDATA + " where
"+DbListHelper.EFFECTIVE_DATE+"between"+DbListHelper.EFFECTIVE_DATE
+ " = '" + fromdate + "' and " + DbListHelper.EFFECTIVE_DATE + " = '" + todate
+ "'", null);
return cursor;
}
这是活动代码
