Bundle Class in Xamarin.Android

Hello All,

In this we will discuss about one of the most important part of the building blocks of Xamarin.Android, and that is Bundle class.

A Bundle class. in nothing but a mapping from values of String types to various other types that can be Parcelable. While transitioning between the states of life cycle of an Activity class, there is a built in functionality to save the states of the application or to save certain aspects of our application and that is with the help of Bundle but Bundle can also be used in many other ways as we saw earlier that while calling the OnCreate() Method, we passes a Bundle and one way to check whether your application is just started again or its just a initial run of your application, we can check that by the value of the Bundle which is initially null, when your application runs for the first time.

1. protected override void OnCreate(Bundle initialBundle)
2. {
3.  base.OnCreate(initialBundle);
4. }

So Bundle can also be think of a simple ways to save the state data and simple peace of data of primitive types. So for the example of that we can run below code and check the value of the bundle.

1. protected override void OnSaveInstanceState(Bundle Initialbundle)
2. {
3.     Initialbundle.PutInt("Count", 1);
4.     base.OnSaveInstanceState(Initialbundle);
5. }
6.

One2One fields in Odoo-9

There is one field that since v6 and above was deleted and no longer used, ie one2one relations field.

If we tried to make it in v6 the error will definitely occurs. OpenERP provides a solution 'combine' to the field many2one but here there is little difference. If the automatic update feature table one2one is a 'destination' when we enter from the table 'source' while it did not happen on the field many2one.

For example you can see below code -

1. class hr_employee(osv.osv):
2.    _inherit = 'hr.employee'
3.    _columns = {
4.        'partner_id': fields.many2one('res.partner','Partner'),
5.    }
7.    def onchange_partner_id(self, cr, uid, ids, partner, context=None):
8.        self.pool.get('res.partner').write(cr, uid, [partner], {'employee_id': ids[0]})
9.        return True
10.     
11. hr_employee()
