Android sqlcipher getDatabaseName（）

Question

在我的项目中，我正确使用库https://www.zetetic.net/sqlcipher/。现在我需要获取数据库的名称。在经典SQLite中，有一个方法getDatabaseName（）而不是密码似乎没有它，我该怎么办？你有好主意吗？

import net.sqlcipher.database.SQLiteDatabase; 
import net.sqlcipher.database.SQLiteOpenHelper; 

    public class DbCrypt extends SQLiteOpenHelper { 

private static final String DB_NAME = "data.db"; 
private static final int DB_VERSION = 1; 

private static SQLiteDatabase db = null; 


public DbCrypt(Context context) { 
    super(context, DB_NAME, null, DB_VERSION); 

} 
@Override 
public void onCreate(SQLiteDatabase db) { 
    DbCrypt.db = db; 
... 
... 
} 


@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
}

在你的SQLiteOpenHelper SQLCipher版的子类，实现getDatabaseName()方法，返回你的数据库名称。你也可以在构造函数中使用它，这样你就不必再重复数据库名称值：

import net.sqlcipher.database.SQLiteDatabase; 
import net.sqlcipher.database.SQLiteOpenHelper; 

    public class DbCrypt extends SQLiteOpenHelper { 

private static final String DB_NAME = "data.db"; 
private static final int DB_VERSION = 1; 

private static SQLiteDatabase db = null; 


public DbCrypt(Context context) { 
    super(context, getDatabaseName(), null, DB_VERSION); 

} 
@Override 
public void onCreate(SQLiteDatabase db) { 
    DbCrypt.db = db; 
... 
... 
} 


@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
} 

public String getDatabaseName() { 
    return(DB_NAME); 
}
