Question

I have table in sqlite that contain only one record and I want to access that in cursor but facing problem I got this exception java.lang.IllegalStateException: get field slot from row 0 col -1 failed

My code is here :

c2=sql.dis();
c2.moveToFirst();
name = c2.getString(c2.getColumnIndex(DbManager.displayname));
ListName.setText("selected list"+name);
}

and this in BD class:

public Cursor dis() {

        try
        {
        SQLiteDatabase db= this.getWritableDatabase();
        String[] todo = new String[] {displayName };        
        Cursor cursor=db.query(displayname, todo, null, null, null,null, null);
        return cursor;
        }
        catch(Exception ex)
        {
            str = ex.toString();
        }

Answer 1

problem of above code is in this line
name = c2.getString(c2.getColumnIndex(DbManager.displayname)); displayname is table name not a column name.
