Let's create Xamarin alert dialog with ok and cancel button.
First create the layout

x
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
android:orientation = "vertical"
android:layout_width = "fill_parent"
android:background = "#d3d3d3"
android:layout_height = "fill_parent">
<Button
android:id="@+id/MyButton"
android:layout_width = "fill_parent"
android:layout_height = "wrap_content"
android:text = "confirm"
android:textColor = "@android:color/background_dark"
android:background = "@android:color/holo_green_dark" />
</LinearLayout>
Open
DialogActivity.cs
and create it's functionalityx
protected override void OnCreate(Bundle bundle) {
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
Button button = FindViewById<Button>(Resource.Id.MyButton);
button.Click += delegate {
AlertDialog.Builder alertDiag = new AlertDialog.Builder(this);
alertDiag.SetTitle("ok or cancel");
alertDiag.SetMessage("want to cancel");
alertDiag.SetPositiveButton("ok", (senderAlert, args) => {
Toast.MakeText(this, "ok", ToastLength.Short).Show();
});
alertDiag.SetNegativeButton("Cancel", (senderAlert, args) => {
