Xamarin Android activity between jump and pass value

Preface

Because of the need, so exposure to this new Android development model, I will be all my learning experience recorded, I hope to be useful to everyone.

Guide

As for activity, people who have studied Android should also understand what activity is and recommend a novice to see the life cycle of the YZF article, which details the life cycle of the activity and some usage.

Body

Activity jumps and transmits values, mainly through the intent class to connect other activity for data transfer.

1. No data jump

New Intent (thistypeof(ADD));                        StartActivity (intent);

The add is the activity that jumps.

2. With Data jump

Mainactivity.cs

New Intent (thistypeof(Uduser));            Intent. PutExtra ("ID", PID);            StartActivity (intent);

where "id" is simply to define a name for this pass-through value, so that it is received and the PID is the value.

Receive pass-through values

Uduser.cs

var yourid = Intent.getstringextra ("ID");
