问题 I'm trying to implement the OpenTok SDK into Nativescript and I've run into an issue that I can't seem to wrap my head around. Per their documentation (https://tokbox.com/developer/guides/publish-stream/ios/#create_publisher) once you create a publisher object you call: [self.view addSubview:publisher.view]; I can't figure out how I would tie this into Nativescript, if it's even possible. My first thought is that I would want a UIView or View element on my page in the XML, then I would call

问题 I'm making a simple app that uses nativescript-audio and I want to play some mp3 samples in the app. The problem is, when I click "Run on Device" in Sidekick, it doesn't transfer any mp3 files I included in the app folder (and therefore I can't play it). What is weird is that if I just change the extension of the file (for example to .jpg), the transfer works fine (and I can even play that file as if it was mp3). So, just to exemplify the problem, if I use this code, it doesn't work: const

问题 I have a Radlistview, where the data switches out based on user query. With loadOnDemandMode="Auto" and when the current query is exhausted, I then call notifyLoadOnDemandFinished(true) . However, when a new query is made, I cannot re-enable loadOnDemand, and new items are not loaded. Is there a way to reactivate loadOnDemand, perhaps with a method on the radListView object? I couldn't find anything in the docs. 回答1: Found the mistake, posting here for anyone else that may have the problem. I

问题 Problem: I have an angular-nativescript app that needs to display some items in a grid. I'm using a RadListView to render the list and after upgrading my angular, {N}, and other library dependencies over the last few months I've noticed the RadListView rendering of the items has gotten unbearably slow. I have multiple "tabs" so you can see different types of items and whenever you switch "tabs" it needs to completely re-render the list with the new times. Before doing some upgrades (which I

问题 I have a RadListView showing a list of items loaded from server. I want to tap on a single item and go to the detail page. I keep getting the same black error page when I tap anywhere on the listing. Here is the component that populates it. import { RadListView, ListViewEventData } from "nativescript-ui-listview"; ... ... public onListLoaded(args: ListViewEventData) { this.updateService.getReports() .subscribe( (data) => { console.log("report data in reports component onListLoaded = "+JSON
