android：在非活动类中使用openOrCreateDatabase

Question

I am creating a new class for database, the first function is to access the database the problem is that I always get error on MODE_PRIVATE

I tried to pass the context as parameter but still shows error

anyone know how to access the database from a non activity class

public class DB {

    public void OpenDB(Context ctx, SQLiteDatabase dataB)
    {

        dataB = openOrCreateDatabase("Schlogger", ctx.MODE_PRIVATE,null);
    }
}

Answer 1

Change

dataB = openOrCreateDatabase("Schlogger", ctx.MODE_PRIVATE,null);

to

dataB = ctx.openOrCreateDatabase("Schlogger", ctx.MODE_PRIVATE,null);

openOrCreateDatabase is a method of Context class so you need a object of Context to call it.

Answer 2

使用context打开数据库ctx.openOrCreateDatabase("Schlogger", ctx.MODE_PRIVATE,null);
