nativescript

问题 I posted this yesterday but I have changed so much of the code today I have basically re-written my question: I have a NativeScript with Angular app using the TabView template and a login form using a modal window over the tabs initially and this appears to be working OK - the login form has no tabs and when logged in I am taken to the TabView. Upon successful login I want to call methods within the tabbed components and update the respective templates with content specific to the logged in

问题 I am creating SegmentedBar in native script.

问题 I installed the platform definitions by adding "tns-platform-declarations": "^2.5.2" However, when I use the definitions in tns-platform-declarations/android.d.ts I can't access certain parts of the API. For instance, I can't access android.support.design.widget.Snackbar private snackbar: android.support.design.widget.Snackbar; because 'android.support' has no exported member 'design' what am I missing? When I go to code complete, I get only 'android.v4' and v4 does not contain a "design"

问题 I have a NativeScript/Angular2 app using Telerik-UI, when I try to display images using ListViewStaggeredLayout directive in a RadListView I get a blank page. Using same code to display text works OK, i.e. 2 columns and staggered layout. Using ListViewGridLayout to display images works as well. I have seen old Telerik documentation showing this is/was possible with images, but I cannot figure out what to set. The HTML code is below. Thanks. <RadListView [items]="pictures"> <template

问题 I'm trying to add a button with custom fonts on the ActionBar on a NativeScript Angular app. This is what I tried so far: <ActionBar class="cp-icon"> <NavigationButton text="" (tap)="goBack()"></NavigationButton> <Image src="res://logo_h_white"></Image> </ActionBar> // Or one of these optio <ActionItem text="" (tap)="goBack()"></ActionItem> <Label text=""></Label> <Button text=""></Button> But none of them seems to be working. I do have the font instaled because I can use in the view.

问题 I'm doing NativeScript work, using the iOS console. When I debug, I usually console.log(something) . However, subsequent triggers of the same event will be blocked on the console. According to https://docs.nativescript.org/angular/tutorial/ng-chapter-3 The iOS console will filter out similar messages and will show them only once. That is why when you keep on clicking the button, you will see hello only printed on the console once. Replace the string "hello" with the following back-tick string

问题 I created a short example of an Angular 2 application built with NativeScript , what I expect is the variable foo to be "foo" at the beginning, then the ngOnInit() first change it to "bar" and then the promise return and I should see "foobar" in the Label, but instead I see "bar".

问题 I'm trying to implement an <ActionBar> that starts off with a transparent background then, as the page is scrolled a background colour is faded in.

Page: <Page xmlns="http://schemas.nativescript.org/tns.xsd" loaded="pageLoaded" backgroundSpanUnderStatusBar="true"> <Page.actionBar> <ActionBar title="Page two">

问题 In my app - i'd like to rename my app for separate variations. For Android, can I rename the app_name resource at .\platforms\android\src\main\res\values\strings.xml Is that the right place? Ideally I would like the apk file to be the same - but I can rename that later. 回答1: Do you have the folder App_Resources under folder App ? If so, change the app name at .\app\App_Resources\Android\values\strings.xml . The one that you change in .\platform will get override by this one every time you
