问题 For better introduction see the blog post about outlets. I use a TabView to navigate through my mobile app written with nativescript (ProtectedComponent). <TabView #tabView tabsBackgroundColor="#f57c00" selectedTabTextColor="#B23010" [(ngModel)]="selectedIndex" (selectedIndexChanged)="tabViewIndexChange(tabView.selectedIndex)"> <StackLayout *tabItem="{iconSource: 'res://tab-icons/cats'}"> <cats-tab></cats-tab> </StackLayout> <StackLayout *tabItem="{iconSource: 'res://tab-icons/dogs'}"> <dogs

问题 In the context of a NativeScript app, I've been struggling to find an efficient, non-hacky way to do what seems pretty simple: have one item in the center of a layout, and another item all the way to the right or left of the layout--something like the images in this question: Center and right align flexbox elements. The items should all be in a single row as they are there. (I've looked through those solutions, but I don't want to add a pseudo-element, and a lot of CSS just doesn't work with

问题 My goal is to use subscriptions in GraphQL in a nativescript vue app to avoid google firebase. It works fine using HttpLink, but it doesn't with websockets. The Error: TypeError: Cannot read property 'slice' of undefined occurs on runtime when importing apollo-link-ws or subscription-transport-ws . As soon as I comment both imports out, the code runs again and I can use GraphQL over http. const Vue = require('nativescript-vue'); import { ApolloClient } from 'apollo-client' import { HttpLink }

问题 When working with a NativeScript application view where a user can enter input, the native application Keyboard Input overlays the TextField component. While this doesn't stop the user from entering text, it disrupts the UX flow and looks bad from a UI perspective.

问题 The first page of my android application has one input field. So what I want is when this page loads I want to show keyboard automatically without doing tap on the input field. 回答1: pkanev's comment is true on ios; ie, just focus on the text field and ios will open up the keyboard.
