Action View Quick Start Guide

For iOS and Android development with Xamarin and Visual Studio
Sample Apps

Action View Components

Getting Started with Action Views

Action View is available exclusively as part of the Action Component Suite by Appracatappra, LLC. To use an Action View in your mobile app include the ActionComponent.ddl and reference the following using statement in your C# code:

using ActionComponents;

Using Dragable

Several of the elements of Action View feature built-in drag handling with optional constraints on the X and/or Y axis. In the following example a ACImageView has been added to our .xib file. In code we will make it draggable, lock it’s Y coordinate in place and allow the X coordinate to be drug within a given range:

// Set thumb to be draggable and apply limits to it's movement
dragThumb.draggable = true;
dragThumb.xConstraint.constraintType = ACViewDragConstraintType.Constrained;
if (iOSDevice.isPad) {
    dragThumb.xConstraint.minimumValue = 140f;
    dragThumb.xConstraint.maximumValue = 920f;
} else {
    dragThumb.xConstraint.minimumValue = 58f;
    dragThumb.xConstraint.maximumValue = 272f;
dragThumb.yConstraint.constraintType = ACViewDragConstraintType.Locked;

The drag controls work exactly the same on Android as well.

User Interaction

Several of the elements of Action View were designed to handle interaction via their touched, moved, or released events. The following is an example of handling a user touch on an ACLabel added to our .xibfile:

// Show graphic when the label is touched
labelWhyChoose.Touched += (view) => {
    // Define Animation

    // Animate property

    // Execute Animation

And here is an example of handling a move event for our dragThumb ACImageViewdefined above:

// Wire-up the moved event
dragThumb.Moved += (view) => {
    // Convert the Left position into an index
    var index = ThumbPositionToIndex(view.Frame.Left);

    // Use shortcut feature of ACImageView to change image
    // NOTE: Existing image is automatically purged from memory before change
    case 0:
        acBadge.FromFile ("ACBadge.png");
    case 1:
        acBadge.FromFile ("ACBadge2.png");
    case 2:
        acBadge.FromFile ("ACBadge3.png");
    case 3:
        acBadge.FromFile ("ACBadge4.png");
    case 4:
        acBadge.FromFile ("ACBadge5.png");

Again, user interaction is the same on Android.


The ACViewController is useful when handling the views controlled by a NavBar Action Component. Create your layout in a .axml file as usual. Next create a new view controller class to handle the layout and inherit from ACViewController, example:

using ActionComponents;

namespace APTest.Android
    public class DocumentViewController : ACViewController 
        #region Private Variables
        // Storage for our UI widgets
        private ACWebView webView;

        #region Constructors
        // Required minimal Constructor
        public DocumentViewController (Activity activity, int resourceID) :  base(activity, resourceID) {


        #region Override Methods
        // Required override of initialize to wire-up your widgets
        public override void Initialize ()
            // Access interface items
            webView = activity.FindViewById<ACWebView> (Resource.Id.webView);

            // Configure Webview
            webView.LoadAsset (String.Format ("{0}About.html",currentComponent));


Use the following code to call the controller, load the view it controls and wire-up its widgets (this example is from a NavBar Action Component):

// Add document view (,true,false).RequestNewView += (responder) => {
    // Bring view into existance
    viewDocument = new DocumentViewController(this,Resource.Layout.DocumentView);

    // Attach view to the button
    responder.attachedView = viewDocument.view;

Trial Version

The Trial version of Action Views are fully functional however the background of several elements are watermarked. The fully licensed version removes these watermarks.
