RuntimeException与SQLite数据库 - Android

我试图改变我的笔记本电脑上的一些我的文件名，我一定搞砸了我的程序。该程序运行良好，直到它需要打开SQLite数据库时，它崩溃。RuntimeException与SQLite数据库 - Android

它曾经工作得很好，所以它与我改变某些文件名有关。我以为我到处去了，修好了它，但它一定没有。我试图更新数据库的版本号，但它没有帮助。

预先感谢您！

Highscores.java

dh.openDB(); //Line 30

DatabaseHelper.java

public SQLiteDatabase openDB() { 
    db = this.getWritableDatabase(); //Line 32 
    return db; 
}

logcat的输出

尝试在创建表查询中使用'TABLE'而不是'DB_TABLE'。 –

Caused by: android.database.sqlite.SQLiteException: near "DB_TABLE": syntax error (code 1): , while compiling: CREATE DB_TABLE HighscoresList (_id INTEGER PRIMARY KEY AUTOINCREMENT,score LONG,percentage INTEGER,category STRING,total_score LONG);

变化DB_TABLE为“表”

你应该总是carfully看logcat的，因为你可以找到你的错误很容易的。一旦发现异常，你应该很容易找到解决的办法。

完美！修复。 – Matt

CREATE DB_TABLE HighscoresList

应该是：

CREATE TABLE HighscoresList

阅读create table syntax。
