Answer 1

有一個錯誤在你SQL查詢語法：

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); 

它說創建表，但它從來沒有命名它。它應該是：

CREATE TABLE MyTableName (_id int ...) 

Answer 2

看到這一行

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); 

它說你的SQLite查詢請檢查語法。我想你沒有給表名。

做create table tablename

Answer 3

的錯誤就在這裏在logcat的輸出：

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); 

它在抱怨你的SQL語法錯誤：您正在嘗試創建一個表，但是你不給這個表一個名字。

的語法是這樣的：create table <tablename> (....

Answer 4

這裏的問題是：

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);
