I am using the Flex SDK within visual studio and trying to dynamically add a button to the stage. Here is a quick example of what I am doing.
public class Test extends Sprite
{
public function Test()
{
init();
}
private function init():void
{
var btnBrowse:Button = new Button();
btnBrowse.label = "Browse";
btnBrowse.x = 0;
btnBrowse.y = 0;
btnBrowse.width=100;
btnBrowse.height=100;
addChild(btnBrowse);
}
}
Nothing seems to show up and the screen is still empty. I am importing mx.controls.* for the button. Could that create an issue since I am not using mxml only as3?
You can't use Flex framework controls in an AS3 Only project. If you are trying to avoid MXML then just create a new Flex Project where the root tag is like:
<FooApplication xmlns="*"/>
And create a new AS3 Class like:
package {
import mx.core.Application;
public class FooApplication extends Application {
// now override something like createChildren to add a button.
}
}
Try changing the base class from Sprite to Canvas.

I'm trying to get this animation/transition working in my Xamarin Android application with Mvx.
I have a recyclerview with cards. When tapping on a card, I now call:
private void TimeLineAdapterOnItemClick(object sender, int position)
{
TimeLineAdapter ta = (TimeLineAdapter) sender;
var item = ta.Items[position];
int photoNum = position + 1;
Toast.MakeText(Activity, "This is photo number " + photoNum, ToastLength.Short).Show();
ViewModel.ShowDetails(item.Id);
}
I'm trying to find out how to translate this java navigation with transition to Xamarin with Mvvmcross:
ActivityOptionsCompat options =
ActivityOptionsCompat.MakeSceneTransitionAnimation(this, imageView, getString(R.string.activity_image_trans));
startActivity(intent, options.toBundle());
I know that within Mvx you can make use of custom presenters, but how do I get hold of, for example, the ImageView of the tapped Card within the RecyclerView which I would like to 'transform' to the new ImageView on the new Activity?
Thanks!
.
Is there a Xamarin Mvvmcross Android Shared Element Navigation
example?
I do not believe so.
I know that within Mvx you can make use of custom presenters, but how
do I get hold of, for example, the ImageView of the tapped Card within
the RecyclerView which I would like to 'transform' to the new
ImageView on the new Activity?
The easiest way that I can think of to achieve the sharing of control elements you want to transition is via the use of view tags and a presentation bundle when using ShowViewModel.
I would suggest making some changes to your Adapter Click handler to include the view of the ViewHolder being selected (See GitHub repo for example with EventArgs). That way you can interact with the ImageView and set a tag that can be used later to identity it.
private void TimeLineAdapterOnItemClick(object sender, View e)
{
var imageView = e.FindViewById<ImageView>(Resource.Id.imageView);
imageView.Tag = "anim_image";
ViewModel.ShowDetails(imageView.Tag.ToString());
}
Then in your ViewModel, send that tag via a presentationBundle.
public void ShowDetails(string animationTag)
{
var presentationBundle = new MvxBundle(new Dictionary<string, string>
{
["Animate_Tag"] = animationTag
});
ShowViewModel<DetailsViewModel>(presentationBundle: presentationBundle);
}
Then create a custom presenter to pickup the presentationBundle and handle the creating of new activity with the transition. The custom presenter which makes use of the tag to find the element that you want to transition and include the ActivityOptionsCompat in the starting of the new activity. This example is using a MvxFragmentsPresenter but if you are not making use of fragments and using MvxAndroidViewPresenter the solution would be almost identical (Override Show instead and no constructor required).
public class SharedElementFragmentsPresenter : MvxFragmentsPresenter
{
public SharedElementFragmentsPresenter(IEnumerable<Assembly> AndroidViewAssemblies)
: base(AndroidViewAssemblies)
{
}
protected override void ShowActivity(MvxViewModelRequest request, MvxViewModelRequest fragmentRequest = null)
{
if (InterceptPresenter(request))
return;
Show(request, fragmentRequest);
}
private bool InterceptPresenter(MvxViewModelRequest request)
{
if ((request.PresentationValues?.ContainsKey("Animate_Tag") ?? false)
&& request.PresentationValues.TryGetValue("Animate_Tag", out var controlTag))
{
var intent = CreateIntentForRequest(request);
var control = Activity.FindViewById(Android.Resource.Id.Content).FindViewWithTag(controlTag);
control.Tag = null;
var transitionName = control.GetTransitionNameSupport();
if (string.IsNullOrEmpty(transitionName))
{
Mvx.Warning($"A {nameof(transitionName)} is required in order to animate a control.");
return false;
}
var activityOptions = ActivityOptionsCompat.MakeSceneTransitionAnimation(Activity, control, transitionName);
Activity.StartActivity(intent, activityOptions.ToBundle());
return true;
}
return false;
}
}
GetTransitionNameSupport is an extension method that just does a platform API check when getting the TransitionName.
public static string GetTransitionNameSupport(this ImageView imageView)
{
if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
return imageView.TransitionName;
return string.Empty;
}
The final step would be to register the custom presenter in you Setup.cs
protected override IMvxAndroidViewPresenter CreateViewPresenter()
{
var mvxPresenter = new SharedElementFragmentsPresenter(AndroidViewAssemblies);
Mvx.RegisterSingleton<IMvxAndroidViewPresenter>(mvxPresenter);
return mvxPresenter;
}
You can check the repo on GitHub which demonstrates this example. The solution is designed so that the presenter does not have to care about the type of the control that is being transitioned. A control only requires a tag used to identify it. The example in the repo also allows for specifying multiple control elements that you want to transition (I did not want to include more complexity in the example above).
I'm writing a Unity editor script and need to make sure that an (UI) Event System exists so I want to create one if it's not already there. But the EventSystem class and StandaloneInputModule class can nowhere be found when trying to import it to a script. What's the matter with this? I can't find any other info on this matter either.
Yes, you can create an EventSystem from the script. As any other component, create a GameObject and add the desired component to it.
using UnityEngine;
using UnityEngine.EventSystems;
public class CreateEventSystem : MonoBehaviour
{
void Start()
{
if (FindObjectOfType<EventSystem>() == null)
{
var eventSystem = new GameObject("EventSystem", typeof(EventSystem), typeof(StandaloneInputModule));
}
}
}
When you add an UI item, the EventSystem object is automatically added. Just drag it into your Project to make it a prefab so you can use it to be instantiated just like any game object.
public GameObject eventPrefab;
void Start(){
if(GameObject.Find("EventSystem") == null){
Instantiate(eventPrefab);
}
}
I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives.
What I am trying to do is add a Start Screen before actually loading the game.
I have a create function that adds all the game elements to the stage:
override public function create():void
// all game elements
{
How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add.
Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great.
Here is my main game.as:
package
{
import org.flixel.*;
public class Game extends FlxGame
{
private const resolution:FlxPoint = new FlxPoint(640, 480);
private const zoom:uint = 2;
private const fps:uint = 60;
public function Game()
{
super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom);
FlxG.flashFramerate = fps;
}
}
}
Thanks.
The way that I usually do it is with a different FlxState - I use one for "Menu", the game itself, and the Game Over screen.
So make a new class that extends FlxState, call it maybe "MenuState" and then say:
super(resolution.x / zoom, resolution.y / zoom, MenuState, zoom);
Inside MenuState, on a button press or something, say:
FlxG.switchState(PlayState);
I have a solution with libraries (DLLs) which are used in 2 identical projects (one for WP7, another for WP8). In one of the libraries I have the code which determines the version of the application.
private static Version mVersion;
public static Version Version {
get {
if (mVersion == default(Version)) {
var lcAssembly = Assembly.GetExecutingAssembly();
var parts = lcAssembly.FullName.Split(',');
var lcVersionStr = parts[1].Split('=')[1];
mVersion = new Version(lcVersionStr);
}
return mVersion;
}
}
The problem is that this code returns the version number of the library itself because of this Assembly.GetExecutingAssembly() code. How to get a MAIN Assembly version and not DLL's?
That's a great question on code-sharing between WP7 and WP8.
The simplest way for you to do that would be to read the AppManfiest.xml file at run-time, get the EntryType and use that to get at the entry point Assembly instance. Here's how a sample AppManfiest.xml looks like once MSBuild did its magic on it:
<Deployment xmlns="http://schemas.microsoft.com/client/2007/deployment" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" EntryPointAssembly="myAssembly" EntryPointType="myNamespace.App" RuntimeVersion="4.7.50308.0">
<Deployment.Parts>
<AssemblyPart x:Name="myAssembly" Source="myAssembly.dll" />
</Deployment.Parts>
</Deployment>
And here's how you would read the file, get the attributes, then get the entry point type and finally the entry point assembly:
private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
var appManfiest = XElement.Load("AppManifest.xaml");
var entryAssemblyName = appManfiest.Attribute("EntryPointAssembly").Value;
var entryTypeName = appManfiest.Attribute("EntryPointType").Value;
Type entryType = Type.GetType(entryTypeName + "," + entryAssemblyName);
Assembly entryAssembly = entryType.Assembly;
}
That's a simple solution and it works. However, that isn't the cleanest architectural solution. The way I'd implement this solution is to have an interface declared in the shared library, both WP7 and WP8 implement that interface and register their implementation with an IoC container.
For example, let's say you need to "DoSomething" in the shared library that's platform version specific. First you'll create have an IDoSomething interface. Let's also assume you have an IoC standing by.
public interface IDoSomething
{
}
public static class IoC
{
public static void Register<T>(T t)
{
// use some IoC container
}
public static T Get<T>()
{
// use some IoC container
}
}
In your WP7 app you'll implement the shared Interface for WP7 and register it once the WP7 starts up.
public App()
{
MainPage.IoC.Register(new MainPage.DoSomethingWP7());
}
private class DoSomethingWP7 : IDoSomething
{
}
You'll also do the same for WP8 in the WP8 app. And in your shared library you can then ask for the relevant interface regardless of its platform version specific implementation:
IDoSomething sharedInterface = IoC.Get<IDoSomething>();
I have a simpler answer. I think you are close with what you are doing. I just used your code with one modification so I can use it with the Telerik controls. Here's what I did. I located your code in my project's App class (codebehind of App.Xaml). I made one change that I think will take care of your problem:
private static Version mVersion;
public static Version Version {
get {
if (mVersion == default(Version)) {
var lcAssembly = typeof(App);
var parts = lcAssembly.FullName.Split(',');
var lcVersionStr = parts[1].Split('=')[1];
mVersion = new Version(lcVersionStr);
}
return mVersion;
}
}
Now I can get the version number by calling "App.Version".
This worked for me:
var appAssembly = Application.Current.GetType().Assembly;
var appAssemblyVersion = appAssembly.GetName().Version;
I tested with WP7.1 and WP8.0.
I use codenameone to develop my mobile application. In this application I implement some classes and codes manually for instance create all forms by hard coding not using codenameone designer for some reason.
By the way I wanted to navigate in forms like what codenameone use, so I use one variable from type of Form called it prevForm and when I want to open a form I set it to current form and then I show new form.
Ok, that is main scenario. In this application I wanna implement internationalization too, so I create my own hashtable (Farsi and English) for this application.
This is my problem:
How can I set or change language and apply it to forms that I opened?
Is my method for navigate between forms are good?
Here is my code:
public class BaseForm extends Form implements ActionListener {
public BaseForm(){
this.setLayout(new BoxLayout(BoxLayout.Y_AXIS));
}
Command exit, ok, back;
Form prevForm;
protected void initForm(){
}
protected void showForm(){
}
protected void showForm(final Form prevForm){
//String name = this.getName();
//if("Reminder".equals(name) || "3Transaction".equals(name))
{
this.prevForm = prevForm;
Form f = this;
back = new Command("Back");
//ok = new Command("Ok");
//delete = new Command("Delete");;
Button button = new Button("Button");
f.addCommand(back);
//f.addCommand(ok);
//f.addCommand(delete);
//f.addComponent(button);
f.addCommandListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if (ae.getCommand().equals(back)) {
//Do Exit command code
System.out.println("Back pressed");
prevForm.showBack();
} else if (ae.getCommand().equals(ok)) {
//Do Start command code
System.out.println("Ok pressed");
}
}
});
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
//Do button code
System.out.println("Action performed");
}
});
}
showForm();
}}
for open nested form I use this code:
LanguageUI lang = new LanguageUI();
lang.showForm(this);
change language [form]:
protected boolean onBtnSave() {
if(isRbFarsiSelected()){
UIManager.getInstance().setResourceBundle(new CommonSettings().getFarsi());
}
else {
UIManager.getInstance().setResourceBundle(new CommonSettings().getEnglish());
}
return false;
}
I also hard code my UI on lwuit, and i have a variable parentForm on every class so i can easily show previous form. For language change i know there is Localization in the resource editor that you can make use of. Below is how you can access it. I guess the trick is how to set the content of the L10N in the res file in code? On the other hand you can create your own helper classes that mirror the methods below.
Resources theme = Resources.open("/theme.res");
theme.getL10N(id, locale);
theme.getL10NResourceNames();
theme.isL10N(name);
theme.listL10NLocales(id)
