Question

第二次插入数据时出现此错误。我第一次在数据库中插入数据时工作正常。但后来我的应用程序被强制关闭或添加了项目但未在listview中显示。当我尝试插入第二条记录时，我的logcat看起来像

和DbAdapter查询

public long insertDL(long imei_id,String c_nm,String i_date, String e_date,String l_no,String cl_no,String c_addr,String l_type,String exe_flg) 
{
    ContentValues values = createContentValues_dl(imei_id,c_nm,i_date, e_date, l_no,cl_no,c_addr,l_type,exe_flg);
    return db.insert(T_DLICENSE, null, values);
}

和CreateTable中的表是

private static final String DRIVINGLICENSE 
= "create table DrivingLicense " +
"(dlid integer primary key autoincrement, " +
"imei_id int(20), " +
"c_nm text not null,"+
"i_date text not null, " +
"e_date text not null,"+
"l_no text not null,"+
"cl_no text not null,"+
"c_addr text not null,"+
"exe_flg text not null,"+
"l_type text not null,UNIQUE(imei_id));";

请帮我插入多条记录。我已经搜索但发现找到解决方案。因为第一条记录正确插入但不超过... Thanx提前。

Answer 1

您要为列imei_id插入相同的值，因为它被声明为唯一，所以不能这样做。

Answer 2

失败的约束意味着您的插入违反了您在表创建中指定的约束。在你的情况下，这是许多字段不为空，一个是键，一个是唯一的。你应该在这里做的是使用调试器，在插入之前停止代码并检查所有值是否符合预期，并满足你的约束条件。

您可能要检查的一件事是字段imei_id - 您指定它是唯一的，但似乎您对函数insertDL的调用将此作为常量0 ..
