You need to add xmlns:gv="@nativescript-community/ui-collectionview"
to your page tag, and then simply use <gv:CollectionView/>
in order to add the widget to your page. Use <gv:Gridview.itemTemplate/>
to specify the template for each cell:
Create a simple array of objects in your JS/TS file.
const items = [
{ index: 0, name: 'TURQUOISE', color: '#1abc9c' },
{ index: 1, name: 'EMERALD', color: '#2ecc71' },
{ index: 2, name: 'PETER RIVER', color: '#3498db' },
{ index: 3, name: 'AMETHYST', color: '#9b59b6' },
{ index: 4, name: 'WET ASPHALT', color: '#34495e' },
{ index: 5, name: 'GREEN SEA', color: '#16a085' },
{ index: 6, name: 'NEPHRITIS', color: '#27ae60' },
{ index: 7, name: 'BELIZE HOLE', color: '#2980b9' },
{ index: 8, name: 'WISTERIA', color: '#8e44ad' },
{ index: 9, name: 'MIDNIGHT BLUE', color: '#2c3e50' }
];
<!-- test-page.xml -->
<Page xmlns="http://schemas.nativescript.org/tns.xsd" xmlns:gv="@nativescript-community/ui-collectionview" loaded="pageLoaded">
<GridLayout>
<gv:CollectionView items="items" colWidth="50%" rowHeight="100">
<gv:CollectionView.itemTemplate>
<Label text="value" verticalAlignment="center"/>
</gv:CollectionView.itemTemplate>
</gv:CollectionView>
</GridLayout>
</Page>
You can also have multiple templates the same way you add them in the builtin ListView
control:
<gv:CollectionView id="gv" row="0" class="cssClass" items="items"
colWidth="colWidth" rowHeight="rowHeight" itemTemplateSelector="templateSelector"
itemTap="gridViewItemTap" itemLoading="gridViewItemLoading" loadMoreItems="gridViewLoadMoreItems">
<gv:CollectionView.itemTemplates>
<template key="odd">
<GridLayout backgroundColor="#33ffff" style="margin: 10 10 0 0">
<Label text="value" verticalAlignment="center"/>
</GridLayout>
</template>
<template key="even">
<GridLayout backgroundColor="#33ffff" rows="auto, auto" style="margin: 10 10 0 0">
<Label row="0" text="value" verticalAlignment="center"/>
<Label row="1" text="value" verticalAlignment="center"/>
</GridLayout>
</template>
</gv:CollectionView.itemTemplates>
</gv:CollectionView>
export function templateSelector(item: any, index: number, items: any) {
return index % 2 === 0 ? "even" : "odd";
}
Import the module into your project.
import { CollectionViewModule } from '@nativescript-community/ui-collectionview/angular';
@NgModule({
imports: [
CollectionViewModule,
],
})
Create a simple array of objects in your Typescript file.
items = [
{ index: 0, name: 'TURQUOISE', color: '#1abc9c' },
{ index: 1, name: 'EMERALD', color: '#2ecc71' },
{ index: 2, name: 'PETER RIVER', color: '#3498db' },
{ index: 3, name: 'AMETHYST', color: '#9b59b6' },
{ index: 4, name: 'WET ASPHALT', color: '#34495e' },
{ index: 5, name: 'GREEN SEA', color: '#16a085' },
{ index: 6, name: 'NEPHRITIS', color: '#27ae60' },
{ index: 7, name: 'BELIZE HOLE', color: '#2980b9' },
{ index: 8, name: 'WISTERIA', color: '#8e44ad' },
{ index: 9, name: 'MIDNIGHT BLUE', color: '#2c3e50' }
];
Add the following to your component HTML.
<CollectionView [items]="items" colWidth="50%" rowHeight="100">
<ng-template let-item="item">
<Label [text]="item.name"></Label>
</ng-template>
</CollectionView>
If you want to use multiple item templates, you can do that very similarly to how you do it for the builtin ListView
control. The only difference is that due to current limitations instead of using the nsTemplateKey
directive you need to use the cvTemplateKey
directive that comes from the CollectionView. (In a future version, once the framework allows it this will be changed and you will be able to use the same directive for the CollectionView
as well)
<CollectionView row="1" [items]="items" colWidth="33%" rowHeight="100" [itemTemplateSelector]="templateSelector">
<ng-template cvTemplateKey="Defender" let-item="item" let-odd="odd">
<StackLayout [nsRouterLink]="['/item', item.id]" borderColor="blue" borderWidth="2" borderRadius="5" verticalAlignment="stretch" class="list-group-item" [class.odd]="odd">
<Label verticalAlignment="center" [text]="item.name" class="list-group-item-text" textWrap="true"></Label>
</StackLayout>
</ng-template>
<ng-template cvTemplateKey="Goalkeeper" let-item="item" let-odd="odd">
<StackLayout [nsRouterLink]="['/item', item.id]" borderColor="black" borderWidth="2" borderRadius="5" verticalAlignment="stretch" class="list-group-item" [class.odd]="odd">
<Label verticalAlignment="center" [text]="item.name" class="list-group-item-text" textWrap="true"></Label>
</StackLayout>
</ng-template>
<ng-template cvTemplateKey="Midfielder" let-item="item" let-odd="odd">
<StackLayout [nsRouterLink]="['/item', item.id]" borderColor="yellow" borderWidth="2" borderRadius="5" verticalAlignment="stretch" class="list-group-item" [class.odd]="odd">
<Label verticalAlignment="center" [text]="item.name" class="list-group-item-text" textWrap="true"></Label>
</StackLayout>
</ng-template>
<ng-template cvTemplateKey="Forward" let-item="item" let-odd="odd">
<StackLayout [nsRouterLink]="['/item', item.id]" borderColor="red" borderWidth="2" borderRadius="5" verticalAlignment="stretch" class="list-group-item" [class.odd]="odd">
<Label verticalAlignment="center" [text]="item.name" class="list-group-item-text" textWrap="true"></Label>
</StackLayout>
</ng-template>
</CollectionView>
For a more complete example, look in the demo-ng
directory.
Register the plugin in your app.ts
.
import CollectionView from '@nativescript-community/ui-collectionview/vue3';
const app = createApp(YourComponent);
app.use(CollectionView);
app.start();
In your component, add the following to make a simple array of objects.
<script setup lang="ts">
import { ObservableArray } from '@nativescript/core';
import { ref } from "nativescript-vue";
const itemList = ref(new ObservableArray([
{ name: 'TURQUOISE', color: '#1abc9c' },
{ name: 'EMERALD', color: '#2ecc71' },
{ name: 'PETER RIVER', color: '#3498db' },
{ name: 'AMETHYST', color: '#9b59b6' },
{ name: 'WET ASPHALT', color: '#34495e' }
]));
</script>
Then add the following XML to your component.
<CollectionView :items="itemList" colWidth="50%" rowHeight="100">
<template #default="{ item }">
<StackLayout :backgroundColor="item.color" >
<Label :text="item.name"/>
</StackLayout>
</template>
</CollectionView>
For a more complete example, look in the demo-vue3
and demo-snippets/vue3 directory.
Register the plugin in your app.ts

{ index: 9, name: 'MIDNIGHT BLUE', color: '#2c3e50' }
];
return {
itemList: items
};
},
// ...
};
Then add the following XML to your component.
<CollectionView
:items="itemList"
colWidth="50%"
rowHeight="100"
>
<v-template>
<Label :text="item.name"></Label>
</v-template>

For a more complete example, look in the demo-vue
directory.
Register the plugin in your app.ts
.
import CollectionViewElement from '@nativescript-community/ui-collectionview/svelte';
CollectionViewElement.register();
In you component, add the following to import Svelte Templates
and to create a simple array of objects.
import { Template } from 'svelte-native/components';
const items = [
{ index: 0, name: 'TURQUOISE', color: '#1abc9c' },
{ index: 1, name: 'EMERALD', color: '#2ecc71' },
{ index: 2, name: 'PETER RIVER', color: '#3498db' },

{ index: 9, name: 'MIDNIGHT BLUE', color: '#2c3e50' }
];
Then add the following XML to your component:
<collectionView
{items}
colWidth="50%"
rowHeight="100"
>
<Template let:item>
<label text="{item.name}" />
</Template>
</collectionView>

This repository includes Angular, Vue.js, and Svelte demos. In order to run these execute the following in your shell:
$ git clone https://github.com/@nativescript-community/ui-collectionview
$ cd ui-collectionview
$ npm i
$ npm run setup
$ npm run build # && npm run build.angular
$ cd demo-ng # or demo-vue or demo-svelte
$ ns run ios|android
The repo uses submodules. If you did not clone with --recursive
then you need to call
git submodule update --init
The package manager used to install and link dependencies must be pnpm
or yarn
. npm
wont work.
To develop and test:
if you use yarn
then run yarn
if you use pnpm
then run pnpm i
Interactive Menu:
To start the interactive menu, run npm start
(or yarn start
or pnpm start
). This will list all of the commonly used scripts.
npm run build.all
WARNING: it seems yarn build.all
wont always work (not finding binaries in node_modules/.bin
) which is why the doc explicitly uses npm run
npm run demo.[ng|react|svelte|vue].[ios|android]
npm run demo.svelte.ios # Example
Demo setup is a bit special in the sense that if you want to modify/add demos you dont work directly in demo-[ng|react|svelte|vue]
Instead you work in demo-snippets/[ng|react|svelte|vue]
You can start from the install.ts
of each flavor to see how to register new demos
You can update the repo files quite easily
First update the submodules
npm run update
Then commit the changes Then update common files
npm run sync
Then you can run yarn|pnpm
, commit changed files if any
npm run readme
npm run doc
The publishing is completely handled by lerna
(you can add -- --bump major
to force a major release)
Simply run
npm run publish
The repo uses https:// for submodules which means you won't be able to push directly into the submodules.
One easy solution is t modify ~/.gitconfig
and add
[url "ssh://[email protected]/"]
pushInsteadOf = https://github.com/
