[mono-android] persistent putextra etc

[John Murray]

Thanks Tiago 

Yes but....

If I declare my class as static - I can't create an instance of it so how do
I use it?  C# does not allow one to create instances of a static class 

 

If I create an instance of the class and declare it static thus - in
activity1

public static vineGar vGar = new vineGar();

it is not visible in activity2

 

I cannot create an instance of the class outside an activity so I'm stumped
how one uses statics 

 

Where and how does ne declare a class or a variable (array) as static so it
is visible across all activities 

An example would be helpful

 

TIA 

John Murray

3)      Is there an easier way? - cant figure how to make a static visible
in all activities -

 

This should work, if your static is public :s I'm using this in my app :s

Sorry to ask for help once again on this 

I have mastered activities and putting and getting extras  but only with
simple data forms such as strings

I've struggled a bit with arrays but as long as they are simple (arraylists
seemed t be a 'no no' when creating a bundle to pass t put extra) 

 

What I really want to do is pass an instance of a data class - just a rather
big form with a few one-to-many fields of data 

e.g.  vehicle details-journey details  - several pax 

 

so I have a class called vehicle which contains and collects the data from
forms which are actually different activities 

I want the instance of this class to be available in all activities 

 

I cannot figure out how to pass the instance of the class using bundle and
putextras 

It seems to be something to do with parcelable data - ie. My   vehicle class
needs to be parcelable 

I've found something on this but it might as well be Fermatts last theorem

 

1)      Am I right about the parcelable stuff

2)      How do I make my class parcelable

3)      Is there an easier way? - cant figure how to make a static visible
in all activities - 

4)      My fall back position is to pass a load of simple arrays or to
serialize to storage between activities 

 

 

 

Thanks in advance
