Passing Custom Object Between Android Activities In C#

I am creating an android app in VS2012 using Xamarin.Android. I am displaying a custom list in Main screen. I need to pass a custom object(with ID,String,String,String properties)

Solution 1:

To coat tail on the servicestack.text solution, you can just download the android DLL's and reference them into your solution. You can use this and add it to your solution, build it separately, as alternatives. https://github.com/ServiceStack/ServiceStack.Text/tree/master/src/ServiceStack.Text.Android

Also I use a couple of methods to convert items back and forth that may be helpful, try

staticpublicstringToJSON(thisobject item)
{
  var myval = JsonSerializer.SerializeToString(item);
  return myval;
}
staticpublic T FromJSON<T>(string code)
{
   var item = JsonSerializer.DeserializeFromString<T>(code);
   return item;
}

Solution 2:

There's an article on using IParcelable in Xamarin here.

Personally, I've always just serialised to JSON, passed a string extra and deserialised it on the other end.

If you're using ServiceStack.Text, which I like, you can do something like this:

intent.PutExtra("SelectedItemId", JsonSerializer.SerializeToString(selectedInsurance));

And on the other end:

var insurance =JsonSerializer.DeserializeFromString<InsuranceReminderBO>(Intent.GetStringExtra("SelectedItemId"))

No need to implement Java.Lang.Object, Java.IO.ISerializable

Solution 3:

After doing a lot of search on Google finally i found a solution here.

Basically I used StartActivity(intent);
