How I create a custom chart like this
with Titanium's Alloy elements (xml, tss, js - no SVG or canvas)? Any suggestion?
One approach which worked for me was the using of a webview and Google Charts.
I stored my "skeleton html page" as local asset, and inside it I wrote the minimum necessary javascript to get the json (from the controller) and to draw the chart.
I didn't need to show data offline so I directly linked the online library but I'm almost sure it's possible to use it offline too.

I'm implementing a react native app (with expo, I don't know if this can be relevant). In this app I'm sending an ajax request to an external service and that service returns a list of URLs related to images in svg format that I need to show in my app.
To show the images I'm using react-native-svg library (I've tried with Svg/Image and with SvgUri). Generally it work properly, but there is some SVG that break my app, because it includes a font-family not supported by my react-native project and the iOS simulator is showing me the error: Unrecognized font family '<FONT-FAMILY-NAME>'.
I've already checked several post on stackoverflow and they all suggest to add the specific font-family to the project, but this solution will not fix my issue in log term as in future I can receive a new SVG file with a different font that will break again my app. I obviously have absolutely no control on the SVG provided by the external service. So, what I'm interested to know is:
Is there any way to add dynamically a font-family to react-native project? For dynamically I mean that the app will add the font to its list when it's required by the SVG file
By using Svg/Image (or with SvgUri) is there any way I can overwrite the font to avoid it to break the app?
Thanks in advance for your answers.
I am working on an e-library project, where we have to display pdf books for children.
I would like to know if I can find some PDF plugins to display PDF nicely.
I used to have the same problem and I figured out, that Android works very well with rn-pdf-reader-js. On the other hand, for ios WebView component is 100% sufficient to display PDF content, so I switched (depends on the platform) between the two of them.
I need to show data in graphical representation like stock app in itunes.
There are many libs but I cant find one giving such functionalities.
Can Any body suggest how to implement.
Try using React-native-svg-charts
which you can control size and colors
here is an Example
I familiarized with Android development and started to read some information about React Native. And one of the problem which I faced with is that I can't see the screen layout.
In Android Studio, for example, I could see the design of my XML layout without running app. Maybe there are such instruments in React Native, but I didn't see them in WebStorm nor VSCode. Maybe I am wrong and they exist, so, can you help me to find them in such situation?
Some modules format the xml document in vscode,
but others have previewable tools.
XML TOOLS
Extension Settings
xmlTools.enableXmlTreeView: Enables the XML Tree View for XML
documents.
xmlTools.enableXmlTreeViewMetadata: Enables attribute and child
element counts in the XML Document view.
xmlTools.enableXmlTreeViewCursorSync: Enables auto-reveal of
elements in the XML Document view when a start tag is clicked in the
editor.
xmlTools.enforcePrettySelfClosingTagOnFormat: Ensures a space is
added before the forward slash at the end of a self-closing tag.
...
I also had the same problem where there is no layout view in VSCode like in Android Studio. My suggestion is to mock out your View containers with coloured boxes. This is an example of designing a screen's header, so I'm making sure the spacing and sizing is all good:
I have been trying to replace my carrousel images with t new photos from my phone camera or album, but for some binding reason, they don't display on the carousel.
I am using Xamarin Media Plugin.
any picture I select should display on the carousel. I have been trying everything in here. IMAGE URL works fine, stored images in the resources folder, works as well. but, for some reason display the images from the media is been a nightmare.
You can clone my sample project # GITHUB
I will appreciate Any help.
Looking at the GITHUB project, easy to understand why no relevant code here, it will require the whole sample project. It seems the carousel is not getting updated when uploading an image, binding?? I am still checking.
