Nativescript-slideshow-busy-indicator

This plug-in allows you to easily create a busy indicator (loader) like the one illustrated using a set of images that you provide. What it does is cycle through the images with a nice transition.

Sample Android

Prerequisites

You need a set of images that will be used to be cycled through. The format can be any format that the NS Image module supports. For best looks icon-like images (with transparency like PNGs) do the job. See demo.

Installation

npm install nativescript-slideshow-busy-indicator --save

Usage

You will have to add xmlns:indicator="nativescript-slideshow-busy-indicator" namespace to your page tag, and then simply use <indicator:BusyIndicator/> in order to add the widget to your page.

The must-set properties are: images - set this property to an array of strings that represent paths to the images you would like to display, like:

public images = ["~/images/01.png", "~/images/02.png", "~/images/03.png", "~/images/04.png"];

isBusy - when set to true, the indicator is visible, when false - it is not

Then you can use the indicator like:

<indicator:BusyIndicator isBusy="{{ isBusy }}"
images="{{ images }}"
indicatorWidth="60"
indicatorHeight="60"
indicatorBorderRadius="30"
indicatorColor="red" />

A few examples:

Output Code
Sample Android <indicator:BusyIndicator isBusy="{{ isBusy }}"
images="{{ images }}"
indicatorWidth="60"
indicatorHeight="60"
indicatorBorderRadius="30"
indicatorColor="red" />
Sample Android <indicator:BusyIndicator isBusy="{{ isBusy }}"
images="{{ images }}"
indicatorWidth="90"
indicatorHeight="90"
indicatorBorderRadius="30"
indicatorColor="yellow"
backOpacity="0.4"
backColor="pink" />
Sample Android <indicator:BusyIndicator isBusy="{{ isBusy }}"
images="{{ images }}"
indicatorWidth="120"
indicatorHeight="100"
indicatorBorderRadius="20"
indicatorColor="red"
backOpacity="0.6"
backColor="black" />
