I'm really new in coding but I know a few things in C#.
I'm learning by myself just for the sake of it, for fun.
I've made some little programs in console and now I'm learning Xamarin.

For now, I've followed the xamarin tutorials (those with the "phoneword" app).

I'm now working on another app for android and I would like to know how to create a new button in code.

Example:
On the main page, the user presses a button that creates a new page where he can fill a form. After he finished, a new button appear on the main page that leads to the form previously filled.
So when the user open the app, he has to choose whether he opens a new form or accesses to the old form (because now there is a new button).

All I want to know is: how do I create this new button ?

I've look everywhere and can't find any working solution. I don't know if that matters, but all I can see is explanations for Xamarin.Forms and that's not what I'm using. I'm using Xamarin Native.

For example, I've tried :

Button b = new Button();

b.Content = "Test";

b.Click += OnClick;

But it's not working. VS returns various errors.
I understand that "Button()" needs parameters, but I don't know what to do.

Someone can give a little help, please ?

PS: I'm not a native speaker, so please don't mind some mistakes with English grammar.

First you need to create parameters of layout & than add those params to button like this

var params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.FillParent, ViewGroup.LayoutParams.WrapContent);    

Button b = new Button(this);

b.SetText("Test",TextView.BufferType.Normal);

b.Click=OnClick;

b.LayoutParameters = params;

Or add layout in your in axml like this

<LinearLayout 

 xmlns:android="http://schemas.android.com/apk/res/android"

 android:id="@id/linear_layout"

 android:layout_width="match_parent"

 android:layout_height="match_parent"

 android:orientation="vertical" >

Than in your activity get you Layout using Id & add button to it.

LinearLayout l_layout = (LinearLayout)FindViewById(Resource.Id.linear_layout);

l_layout.Orientation = Orientation.Horizontal;

Button b = new Button(this);

b.Click=OnClick;

b.SetText("Test",TextView.BufferType.Normal);

l_layout.AddView(b);

With this You can create the button You only need to add the size of the button and add it to some layout.

Xamarin.Forms

Button button = new Button();

button.Text = "Title";

Xamarin.Android

Button button = new Button(this); //if your using a fragment you have to use this.Activity

button.Text = "Title"; 

Xamarin.iOS

UIButton button = new UIButton();

button.SetTitle("Title", UIControlState.Normal);

Xamarin forms button example

var Tittlebutton= new Button

    {

    Text = "Title"

    };
