I tried to find an example for content loading animation (to learn how to implement one in my app). But I couldn't find one.
What I want is: There are 4 listboxes in my mainpage and I want to show a loading animation until the listboxes have completed loading their data.
For example,IMDB application has a loading animation like I want. (You can watch it here http://www.youtube.com/watch?v=AV9BoyGm7Fo)
Any ideas on how to create this?
Thanks
Please refer to these links, as they seem to provide the exact solution to coding this standard loading animation:

I would just like to know of something is possible as I am very new to Xamarin and I am on a time limit for an assignment. I don't mind some trial and error, but don't want to waste the time if it isn't possible
I want to have an animated gif as an activity indicator (it is a logo).
I have it working in a WebView - is it possible, in Xamarin,Forms to have this appear as an overlay while waiting on long running methods?
For example. if user clicks on a button, the app gets some info from a webservice then displays in a page. While waiting I would like to show the webview (or any other way to show an animagted gif).
So I am not asking for the code, but just if it is posible.
Thanks in advance
I was able to work this out
With the animated(loading) gif running in the WebView page I called a couple of async methods using following
await Task.WhenAll(method1(), method2());
await Navigate.PushAsync(new NextPage(var1, var2));
The laoding gif (which is an animated logo) runs until the tasks are complete then navigates to the next page
Using an ImageView apparently this doesn't look like its possible to playback animated Gif's as can be seen here http://forums.xamarin.com/discussion/17448/animated-gif-in-image-view.
So i very much doubt the ActivityIndicator would, if it could. In the ActivityIndicator I can't see any functionality to change the content of the what is shown when it is busy.
You could always create your own animated image view by creating a custom renderer instead however. It isn't particularly hard to cycle images at pre-determined gaps if you have a list of the images split up.
GIF images can be used in Xamarin forms to show custom activity indicator, since in Xamarin forms it is not possible to show GIF images directly web-view must be used. For android image must be placed inside assets folder and Build Action must be set to AndroidAsset. For iOS image must be placed inside resources and Build Action must be set to BundleResource. AbsoluteLayout can used for placing the image to center, IsBusy property of mvvm helpers nuget can used for controlling the visibility of the activity indicator. Dependency service must used for getting the image path. You can check this https://github.com/LeslieCorrea/Xamarin-Forms-Custom-Activity-Indicator for example.
Xamarin.Forms now supports .GIF, from version 4.4-pre3 and up on iOS, Android and UWP. Before using, first add the .GIF to the platforms projects, or as an embedded resource in the shared project and then use it like a regular image. The API on the Image control has been extended with the IsAnimationPlaying bindable property.
For e.g., loader.gif is added in all platform projects, then below code make it animating.
<Image Source="loader" IsAnimationPlaying="True" WidthRequest="36" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand" />
I currently have a series of 8 separate html files, with the idea that each one is a separate page in an iPad app. I have used jQuery Mobile to implement the page swipe between pages by using the 'data-next' and 'data-prev' attribute. However, the results are not great as i sometimes get a page flicker when i swipe, and css animations are very choppy when I test it on an actual iPad. I am also getting a 1 second delay before the actual swipe happens. I know JQM has a default delay of 300ms, but this is waaay longer! I have tried using the css 'translate3d' technique on animated elements, but it doesn't seem to fix it. I'm putting it down to JQM just being buggy as hell.
So my question is this..Is it possible to bring these files into Xcode, as separate independent html files, and implement the page swipe within Xcode itself?
No Not possible.
XCode allows you to create/edit UI and Transitions of cocoa touch controls only. However you can just edit these html/javascript files in XCode.
I just wondering how to make panorama start-up animation like music+video or picture app. Notice the sliding 3d animation when we open music+video/picture/marketplace app.
When I create panorama project using VS 2010 Express, the animation is just from right to left.
How do i make that animation?
If I understand you correctly - take a look to Wp7 silverlight toolkit - page transitions
The animations are there, but if you have too many things running on the UI thread, the animation will be hard to see since loading will be choppy. To test this, just make a new page with a default panorama inside it and observe the animation while its empty. Zune app will always be faster, its run on native code from my understanding.
I have written a windows phone application. When the application starts up it shows the splash screen which is cool and i can change the image. But is there a way to add a loading animation like those dots moving across the screen.
It would be nice if i can add one of those animation in the splash screen. Can it be done. if yes please add in your answers.
As of right now there is no way to replace the loading image that shows up with an animation. Although there are workarounds:
Remove the image all together. Might want to be careful though because Microsoft requires that the application show some kind of feedback to the user within a few seconds of launching the app. Use this only if your app loads really fast.
Display a snap shot of the loading screen as an image so when the app does load you can show an animation with the same background image and it appears that its the same loading screen.
In your case I would recommend using a popup control with a loading animation inside (Option 2). To learn how to create a popup go here. Or if you want a well documented popup I know telerik has there own version as well.
Next place the loading message in a textblock or put your own image and animation inside of the popup. Obviously the easiest animation would be to use the Performance Progress Bar in the silverlight toolkit.
Now what you'll want to do is set the popup opened by default. Whenever your processing is done all you have to do is set the popup visibility to hidden in your C# code.
Some examples of how this is implemented can be found here:

Can someone give an example on how to animation page navigation in WP7?
I actually only just want to use the flip animation used in most default installed application i.e. the Settings application.
Maybe this can be something of use?
