I'm working in a Blackberry app (OS 5.0) and need to show recent tweets of the user.
I'm able to get the data from Twitter's end. Now after parsing the entities (hashtags, urls, user-mentions etc), I need to display them with separate formatting (color, bold etc). So I'm using different LabelFields for different parts of the tweet.
But LabelFields are by default block elements. How do I put those LabelFields inline, so that it looks like how it is shown in Twitter?
like this:
Others have suggested RichTextField but you'd have to write your own text filter to colour the syntax - it's going to be a lot of effort. If having the clickable links inline is a must then personally I'd use a BrowserField but that would mean your logic would have to output a full screens worth of tweets into html (screens don't like having more than one browserfield - it's doable with more than one but there's some hacks) and manage the click events - more complications.
Alternatively you could do something like this: http://devblog.blackberry.com/2009/10/how-to-use-table-view-layout/ You wouldn't have clickable regions within the text body but it'd still be using native fields instead of 'cheating' with markup, probably the best way.
I've found that there's a component in Blackberry SDK called ActiveRichTextField which automatically scans its contents and parses links making them focusable and clickable. Furthur it'll also parse entities if Twitter app is installed in that device. For now it solves my problem. Thanks guys.

I have a task to implement but after some thought I don't really know from where to begin.
What I need to achieve:
Lets take as example BestBay web site. From my app I would like to create a certain query which will go/use to BestBay search type what I need and bring me the result. On my device I would like to show it as 10 views of the first items the website returned. For instance if I type "tvs" I will get a list of tvs so I would like to show this list on my device with the price and the link to the item (at least for the 10 first items).
I have experience with native apps(i didn't worked with web apps).
I can't use Best buy api.
I am not sure from where to begin.
I read about YQL.
I thought maybe to use the web page with the results as html and parse it to the objects I need.
Did anyone do something similar and can give me some starting point.
How to approach this kind of problem.
(tutorials/documentations/sample code something that can help me to start).
Tnx a lot.
In the end I decided to do it by HTML parsing:
parsing HTML on the iPhone
How to Parse HTML on iOS
I wanted to know the technology decision behind the iOS Google app.
As we can see, in the app's Google Now feature it renders many different card templates for different scenarios, and those templates seems to be very flexible based on server inputs.
I was wondering if this is implemented all based on HTML5? or they just have many templates built in and render them locally? I'd vote for the HTML5 route but not sure if this still involved some native code to make it more responsive?
Thanks!
As we (well, most of the community) are not Google employees we can't tell you what they really did, but I'd say that it is possible to do this dynamically in the app.
We did develop something similar that responds to definitions sent by the server and transforms them to custom designed forms following basic rules.
Google reuses the design of those cards for different plattforms, the easiest solution should be showing some WebView and using HTML5.
I agree with Kevin, as this answer is entirely based on personal opinion, too.
The way I would go is to create a card class which will load some JSON data and format it with HTML and CSS. Looking at each card it would be hell to format things that way natively. I mean, attributed strings is not the way to go. Too much logic for deciding which card get a bigger text or a picture.
Additionally, the top header is most likely "localized" as well, so you get the location and load a localized image. But that is Google by nature.
I want to create a native ios application where people have to sign different contracts. Each contract contains text and input fields such as drop down and textbox. Now each contract might have different number of input fields and these might be totally different.
Any input in the best way to solve this problem? It seems like a lot of work to dynamically generate UI in code and reformat the contracts in a way that can be rendered by ios? As I cant send the pdf or doc itself.
One solution may be you can have categories(sector-1,sector-2 etc) and related sample contract from. In those sample forms you can handle dynamic controls which definitely a few.
How can I stop search engines indexing part of my page? Is there an HTML5 element for this?
Its just a line of text that I want to hide (a co-worker doesnt want their name on google for some reason). Im thinking that I could inject the text with javascript, but I have heard google does sometimes look inside javascript files.
I also thought of using images instead of text, but im concerned how this will look cross device and platform. Ive noted text rendering can differ on mac and pc and thats before ive had to think about mobile devices, retina displays, etc.
Thanks
You can't hide content unless you use the methods you've already outlined above. Your best bet is to use JavaScript in an external file and then block that file using robots.txt.
I have to make formatting available for a text box in a web based application just like the options available here to make selected text bold or in italics. I don't know where to start. can anyone please guide me.
Thanks
Why reinvent the wheel? Use something that already exists:
TinyMCE
CKEditor
Here's a list of ten different rich text editors that will do what you need.
http://www.queness.com/post/212/10-jquery-and-non-jquery-javascript-rich-text-editors
Depends on what you're going to be coding in, but I'm sure most languages have built-in types for text boxes that can handle formatted text (not unlike the one I'm typing in right now), and probably have a method that returns the contents of the box.
All you'd need is to figure out is the format code, if you want to store this text and open it elsewhere.
If you want to create from "scratch", you can use any JavaScript framework to ease your work. There are many "good" frameworks out there:
jQuery, ExtJS, GWT, YUI, etc. Just choose the one that suits to your need.
