ListView

API Reference: UI.ListView

ListView is a View that displays given items as a one-column vertical list. Interaction with each item in the list is possible.

Return Value of onRowType
  • If ListViewItem's are created from UI Editor, you shouldn't be returning 0 in onRowType method.
Callback Functions
  • Define your Listview calback functions before Page.onShow

  • You can define them in Page.onLoad

Usage of ListView

There are two ways to use ListView on Smartface

  • Create the component skeleton in code, like creating your elements in Javascript
  • [Recommended] Using Smartface UI Editor to create component skeleton and reuse it.

For more information about the difference of two, refer to the document below:

Using UI Editor and Classes
info

For ease of showcase, the code examples here creates the necessary components directly from code. Smartface recommends to use Smartface UI Editor to use ListView. More information is located at the document below:

Using ListView and ListViewItem from Code

info

This method is not recommended when using 1 type of ListViewItem.

It is possible to create your ListView and ListViewItem using Page code. For this approach, you should use UI.ListView.onRowCreate method to create your layouts and UI.ListView.onRowBind to assign your data.

note

The components in the example are added from the code for better showcase purposes. To learn more about the subject you can refer to:

Adding Component From Code

As a best practice, Smartface recommends using the WYSIWYG editor in order to add components and styles to your page or library. To learn how to use UI Editor better, please refer to this documentation

Scrolling to a ListViewItem Programmatically

API Reference: scrollTo

info

When using scrollTo method, you should check if ListView has enough data in it.

this.data = [{ text: "Smartface" }];
/**
* This may cause unexpected behavior since the listView doesn't have
enough length to scroll to.
*/
this.listView1.scrollTo(3);

// You should do it like this
if (this.data.length > 3) {
this.listView1.scrollTo(3);
}

Sample ListView Implementations

info

For ease of showcase, the code examples here creates the necessary components directly from code. Smartface recommends to use Smartface UI Editor to use ListView. More information is located at the document below:

Using ListView with UI Editor

Using Multiple ListViewItem's

For multiple ListViewItems, you cannot use Smartface UI Editor to drag\&drop your ListViewItem elements. You should specify which elements to choose from code. However, you can create your skeleton component from UI Editor and reference it by importing it.

import LviElements from "components/LviElements";
import LviItems from "components/LviItems";

// ...your page code.
this.listViewItemIndex = 0; // Initialize this in constructor
this.listView1.onRowCreate = (type) => {
let listViewItem = type === 0 ? new LviElements() : new LviItems();
this.listView1.dispatch({
type: "addChild",
component: listViewItem,
name: `myListViewItem${++this.listViewItemIndex}`,
});
// ...other necessary logic
return listViewItem;
};

Lazy Loading (Pagination)

Lazy loading of ListView is easy on Smartface Native Framework. It is possible with:

  • onScroll event
  • onRowBind event
danger

Please note that onScroll event will be fired while user scrolling the ListView. This means while you downloading your content for lazy loading, onScroll event will continue to firing. You should check that. We recommend to use onRowBind for lazy loading to get over from this problem.

Sticky Items

Some components within the page will appear constantly at the bottom of the page. As the user scrolls down, those items will remain within the same absolute position.

This is a simple example of Sticky Items made with ListView and FlexLayout.

caution

Be sure that you set the backgroundColor of the ListViewItem to any color other than transparent. If you don't, the swipe item backgroundColor will overlap with the ListViewItem backgroundColor.

ListViewItems can be selected and moved to a different location.

Zebra Design

If you need to apply a Zebra Pattern, you should change the background of the ListViewItem in every odd(or even) index, depending on your design.

First, you should create a component on Smartface UI Editor to for your element. For this, a simple ListViewItem with one label inside is enough.

info

For Component Theme, baseTheme was used in this documentation. It is highly recommended to create your own theme and define your styles there. Refer to the document below for more information:

tip

Do not forget to add your new page to your router.

Smooth Search - iOS Search Behavior

Since Smartface is Native Cross-Platform Framework, you can directly use iOS search behavior but you need to access Native-API-Access and your code will only work for iOS. To make it work for both platforms, we need to mimic it using various UI manipulations.

After creating the component, you can drag & drop it to your newly created page.

info

Note that for ListView element, the LviElement component from previous Zebra Design was used. You can use any ListViewItem component, it is not related to Smooth Search implementation.

If you also want to use Zebra design together with smooth scroll, you can copy the onRowBind method from the previous example page code.

ListView Index

With list view index, you can navigate to a specific item in the list.
