准备“创建表选项...创建表分数...我将在我的程序中发布所有其他代码，以便我可以在遇到更多问题时询问（接近“创建”：语法错误）） .

这是我的表（在 DBHelper.java 中）：

final static String sqlcreate=

        "create table option (id integer primary key autoincrement," + 
        "volume boolean not null, vibrate boolean not null, theme text not null) " +    

        "create table score (id integer primary key autoincrement," +
        "score text not null, difficulty text not null, date date not null, );";

这是我的 DBFunction.java：

public int addScore(String score, String difficulty){

ContentValues values = new ContentValues();

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); 
    Date scoredate = new Date();    
    values.put("score", score);
    values.put("difficulty", difficulty);
    values.put("date", dateFormat.format(scoredate));   
    return (int) db.insert(tableScore, null, values);
}`

这是我的 OnClick()：

if (v==btnadd){

        String vol = tbtnvol.getText().toString();
        String vib = tbtnvib.getText().toString();
        String theme = themename.getText().toString();
        options.open();
        options.addOption(vol, vib, theme);
        options.close();
        Toast.makeText(this, "Data has been added", Toast.LENGTH_LONG).show();
    }`

修正您的查询如下：

"create table option (id integer primary key autoincrement," + 
"volume boolean not null, vibrate boolean not null, theme text not null); " +

"create table score (id integer primary key autoincrement," +
"score text not null, difficulty text not null, date date not null);";

您错过了分号并在查询中留下了一个额外的逗号

您需要用分号分隔其中的两个 SQL 语句。

... theme text not null); " +   <-- semi colon added here
"create table score ...

您的第一个查询没有错误

create table option (id integer primary key autoincrement,volume boolean not null, vibrate boolean not null, theme text not null)

第二次查询

create table score (id integer primary key autoincrement," +

“分数文本不为空，难度文本不为空，日期日期不为空）

我已经检查过它现在工作正常

从末尾删除

"create table score (id integer primary key autoincrement," +
    "score text not null, difficulty text not null, date date not null, );";

写如下

"create table score (id integer primary key autoincrement," +
    "score text not null, difficulty text not null, date date not null);";

是的，还有放；最后正如格雷厄姆所说
