This repo only supports NativeScript pre-6.0. The latest version of the plugin supporting NS 6+ is availble as part of ProPlugins.
A NativeScript GridView widget. The GridView displays data in separate cells, each cell representing one data item. For iOS wraps up UICollectionView and for Android wraps up RecyclerView
Run the following command from the root of your project:
tns plugin add nativescript-grid-view
This command automatically installs the necessary files, as well as stores nativescript-grid-view as a dependency in your project's package.json file.
There is no additional configuration needed!

itemLoading

itemTap
Triggered when the user taps on an item in the GridView. -
loadMoreItems
Triggered when the generated items reached the end of the items property. -
scroll
Triggered when the GrdiView is scrolled by the user. from theargsyou can get the new horizonta/vertical offset.

You need to add xmlns:gv="nativescript-grid-view" to your page tag, and then simply use <gv:GridView/> in order to add the widget to your page. Use <gv:Gridview.itemTemplate/> to specify the template for each cell:
<!-- test-page.xml -->
<Page xmlns="http://schemas.nativescript.org/tns.xsd" xmlns:gv="nativescript-grid-view" loaded="pageLoaded">
<GridLayout>
<gv:GridView items="{{ items }}" colWidth="24%" rowHeight="15%" padding="5" itemTap="gridViewItemTap" itemLoading="gridViewItemLoading" loadMoreItems="gridViewLoadMoreItems">
<gv:GridView.itemTemplate>
<GridLayout backgroundColor="#33ffff" style="margin: 5">
<Label text="{{ value }}" verticalAlignment="center"/>
</GridLayout>
</gv:GridView.itemTemplate>
</gv:GridView>
</GridLayout>
</Page>// test-page.ts
import { EventData, Observable } from "data/observable";
import { ObservableArray } from "data/observable-array";
import { Page } from "ui/page";
import { GridItemEventData } from "nativescript-grid-view";
let viewModel: Observable;
export function pageLoaded(args: EventData) {
const page = args.object as Page;
const items = new ObservableArray();
for (let loop = 0; loop < 200; loop++) {
items.push({ value: "test " + loop.toString() });
}
viewModel = new Observable();
viewModel.set("items", items);
page.bindingContext = viewModel;
}
export function gridViewItemTap(args: GridItemEventData) {
console.log("tap index " + args.index.toString());
}
export function gridViewItemLoading(args: GridItemEventData) {
console.log("item loading " + args.index.toString());
}
export function gridViewLoadMoreItems(args: EventData) {
console.log("load more items");
}You can also have multiple templates the same way you add them in the builtin ListView control:
<gv:GridView id="gv" row="0" class="{{ cssClass }}" items="{{ items }}"
colWidth="{{ colWidth }}" rowHeight="{{ rowHeight }}" itemTemplateSelector="templateSelector"
itemTap="gridViewItemTap" itemLoading="gridViewItemLoading" loadMoreItems="gridViewLoadMoreItems">
<gv:GridView.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:GridView.itemTemplates>
</gv:GridView>export function templateSelector(item: any, index: number, items: any) {
return index % 2 === 0 ? "even" : "odd";
}Import GridViewModule in your NgModule:
import { GridViewModule } from 'nativescript-grid-view/angular';
@NgModule({
//......
imports: [
//......
GridViewModule,
//......
],
//......
})// app.module.ts
import { GridViewModule } from "nativescript-grid-view/angular";
@NgModule({
bootstrap: [
AppComponent
],
imports: [
NativeScriptModule,
AppRoutingModule,
GridViewModule,
],
declarations: [
AppComponent,
ItemsComponent,
ItemDetailComponent
],
providers: [
ItemService
],
schemas: [
NO_ERRORS_SCHEMA
]
})
export class AppModule { }<!-- my.component.html -->
<GridLayout class="page">
<GridView [items]="items" colWidth="30%" rowHeight="100">
<ng-template let-item="item" let-odd="odd">
<StackLayout margin="10" [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>
</GridView>
</GridLayout>If you want to use multiple item templates, you can do that very similarly to how you do it for the builtin ListView control.
<GridView row="1" [items]="items" colWidth="33%" rowHeight="100" [itemTemplateSelector]="templateSelector">
<ng-template nsTemplateKey="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 nsTemplateKey="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 nsTemplateKey="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 nsTemplateKey="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>
</GridView>This repository includes both Angular and plain NativeScript demos. In order to run those execute the following in your shell:
$ git clone https://github.com/peterstaev/nativescript-grid-view
$ cd nativescript-grid-view
$ npm install
$ npm run demo-iosThis will run the plain NativeScript demo project on iOS. If you want to run it on Android simply use the -android instead of the -ios sufix.
If you want to run the Angular demo simply use the demo-ng- prefix instead of demo-.
