如何将编辑文本动态添加到Xamarin Android

Question

XAMARIN ANDROID DYNAMIC CLICK: I want the spinner, edit text and positive button to be placed side by side such that when the button is clicked by any user, it regenrates the same content (spinner, edittext and a negative button) and for every click on the positive button the same thing happens while for every click on the negative button, the content where the negative button is will be removed.

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layoutTeste"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <Spinner
        android:id="@+id/spn"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignTop="@id/et" />
    <EditText
        android:id="@+id/et"
        android:layout_height="wrap_content"
        android:layout_width="200dp"
        android:hint="Enter a Value"
        android:layout_gravity="center"
        android:layout_marginLeft="70dp" />
    <Button
        android:id="@+id/btnDisplay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/btnDisplay"
        android:layout_alignParentRight="true"
        android:layout_alignBaseline="@id/et" />
</RelativeLayout>

Dynamically you can create view in xamarin android programmatically for your need.

For Example

LinearLayout LL = FindViewById<LinearLayout(Resource.Id.Linear_MS); //root layout
var param = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.WrapContent);
        param.SetMargins(20, 20, 20, 10);
var et = new EditText(this);
LL.AddView(et, param);

In Xml side by side design use this.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layoutTeste"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:id="@+id/ll"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="3">
    <Spinner
        android:id="@+id/spn"
        android:layout_height="wrap_content"
        android:layout_width="0dp"
        android:layout_alignParentLeft="true"
        android:layout_weight="1"
        android:layout_alignTop="@id/et" />
    <EditText
        android:id="@+id/et"
        android:layout_height="wrap_content"
        android:layout_width="0dp"
        android:hint="Enter a Value"
        android:layout_gravity="center"
        android:layout_weight="1"
         />
    <Button
        android:id="@+id/btnDisplay"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:text="@string/btnDisplay"
        android:layout_weight="1"
      />
    </LinearLayout>
</RelativeLayout>
