Hi Daniel,

Your post is awesome with lot of information.
I am dealing with the same situation where we need to access sitecore content along with financial data from REST. REST is hosted on the main sitecore site. We have only one communication channel available between Mobile app/site to server via REST.svc. I already have setup the device with querystring(api=1). I was wondering what can be used as a layout? I have tried the .aspx with no success yet. Can you give me some more information about accessing the sitecore for API from REST? Is there a way to avoid direct sitecore access from the mobile app and still get the response in xml/c#/json object?

We are doing this to get the Sitecore context to gain the benefit of sitecore resources rather than just accessing the content by targeting the field values.

Any help much appreciated,

Regards,

Nice note on REST as a design pattern. It’s good to have this foundational knowledge in mind.

It seems that the Boston Globe’s challenge is really nice contest because it encourages the developers to come up with application to benefit the Boston as a place. And congratulations in being honored with Boston Hack Day grand prize. It is interesting that you came up with a concept to win the award in only a weekend. Good luck on your future contests.

Thankyou for this!
I had been searching for an example on how to implement this.
I expected it to be pretty straight forward, and am happy to see it is.

the projects zip would be nice :)

Gallery is somewhat limited in that all the child views have to be the same size. I’m working on backing your view with an adapter like a listview so that views can be recycled. In your examples you have pretty lightweight views, but I’d like to load heavier views and loading 30-40 of them like above would not be feasible memory wise.

I’m new to Android development, and this post is exactly what I’m trying to do, but I’m having trouble figuring out how to set up the layout xmls and also the array for the articles. Can anyone offer some guidance in these areas? Thanks in advance for any assistance.

Looks like the 2.2 Gallery has implemented recycling, but on 2.1 devices you’re stuck with the old implementation. Also, Gallery is dropping the views off screen which in the case of a widget like we are after here, nothing is being kept on either side of the displayed view because those are ‘off-screen’.

On another note, I’m also seeing that onFling is always being passed null for the first motion event. There are sporadic reports of this on SO and the google group, but no real solutions. Something is intercepted it somewhere in the stack and mucking with it.

Hi

Thank you for your great example. project zip would really be very nice, or you maybe can at least help me with one thing.as soon as I put textViews inside, everything works fine, but actually I need custom component to be in the horizontal view.

I fail trying to draw only one simple rectangle in fullscreen mode, with 10px margin from the edge of screen. I can only do it in first “page” but it never scrolls to another page.

in my application, only first screen is always drawn, although I put different canvas.drawText to each sub-view.

I would really appreciate, if you could help me with that

Thanks a lot

@Jonathan Have you finished your version with view recycling? Would love to see it if you have.

But you don’t write an xml android file?

I am new to Android and Java, please could you tell me how I use this class in an Android project. This is just what I am looking for.
Thanks

Great work. I’ve incorporate the scroll logic. However, on my phone, smoothScrollTo doesn’t always work. By that, I mean that there are times when ACTION_UP is called, the code correctly computes the next page to scroll to (as per the log), but smoothScrollTo() doesn’t scroll all the way to the next page.

I’m running Android 2.2 on an LG Optimus. Any one else have this problem?

This works amazing!
Anybody has an idea how to set the position to a certain x-position?

very helpful code mate thanks

Android’s Gallery Widget has a lot of limitations and features that you need to get rid of in order to implement this behavior consistently. I have extended Gallery successfully for a widget I had created before, but I needed to create another “snapping” widget that made more sense as a ScrollView, and your article helped me a lot. It’s working very well and a ScrollView is a lot easier to extend and work with than the Gallery (e.g. no Adapters needed).

So thanks for this — very useful!

I was tweaking away, googling, etc. And I came across this:
http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html

Seems the way to go

Would u please give me an example for this part of the code:

for(int i = 0; i< items.size();i++){
LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.unlocked_page,null);
//…

//Create the view for each screen in the scroll view
//…
internalWrapper.addView(featureLayout);
}

'Coz I didn't understand how it works… Firstly, we defined "private ArrayList mItems = null;" and we never changed it, or at least i didn't get what we need to do over there, how we can use it… I just got little bit confused :/ Thanks in advance

Update on the silent null exception where e1 is null:

I was getting this too – a quick google implies that it is caused by having an onclick listener on a child of the scrollable view which is trying to highjack one of the gestures.

It looks like this is negatively affecting the scrolling experience – right to left SWIPES are not working – only drags to 50%.

I have not been able to find a fix to this problem. Any chance you could take a look?

All the best and thanks for this code!
Max.

project code for this example is more useful please share zip file

Android viewPager/ viewfliper is the good replacement for this… like google play

Hi Joel,

First, congratulations for this post, very intersting, i was searching for this a while. Can you give all your project ? For example ArticleListItem and the layout xml. I need run and adapter to my project. I cant run this example, i make some modifications, but isn´t the same result.

Thanks

hi
thank a lote
i used your code
god bless you

Hi,

That’s a fantastic job.

I used your example and customized to my need. where I inflate a screen and add to Linear Layout, it does the job but it doesn’t fit the full width of the screen even though i say fill parent and given hard coded value to make it occupy full width. But no luck. and as a result few part of the second screen does show on the first screen..

Please help me in this..

Thanks & regards,
Kiran
