4 个答案:

答案 0 :(得分：0)

SQL 查询语法中存在错误：

create table  (_id integer primary key autoincrement, question text not null, a text not null, b text not null, c text not null, d text not null, answer text not null, subject text not null);

它说创建表，但它永远不会命名它。它应该是：

CREATE TABLE MyTableName (_id int ...)

答案 1 :(得分：0)

看到这一行

06-08 22:11:30.610: E/AndroidRuntime(320): Caused by: android.database.sqlite.SQLiteException: near "(": syntax error: create table  (_id integer primary key autoincrement, question text not null, a text not null, b text not null, c text not null, d text not null, answer text not null, subject text not null);

它说你的SQLite查询请检查语法。我想你还没有给出表名。

做create table tablename

答案 2 :(得分：0)

错误就在logcat输出中：

06-08 22:11:30.610: E/AndroidRuntime(320): java.lang.RuntimeException: Unable to start activity ComponentInfo{poo.sushie.ourproject/poo.sushie.ourproject.MyprojectActivity}: android.database.sqlite.SQLiteException: near "(": syntax error: create table  (_id integer primary key autoincrement, question text not null, a text not null, b text not null, c text not null, d text not null, answer text not null, subject text not null);

它抱怨SQL中存在语法错误：您正在尝试创建表，但是您没有为表命名。

语法如下：create table <tablename> (....

答案 3 :(得分：0)

问题在于：

Caused by: android.database.sqlite.SQLiteException: near "(": syntax error: create table  (_id integer primary key autoincrement, question text not null, a text not null, b text not null, c text not null, d text not null, answer text not null, subject text not null);
