Android SlideShow Widget

A set of widgets to create smooth slide shows with ease. The slide show components are fully customizable and are not limited to pictures, you can slide whatever you want to (texts, etc.).

Demo

A demo of the widget is worth a thousand words. You can download it for free on Google Play.

Usage

Including the library

The easiest way to get the library included in your project is by using Gradle. Simply add the following line to your dependencies block:

dependencies {

  compile 'com.marvinlabs:android-slideshow-widget:0.4.+@aar' 
}

Of course, you can replace the version number by whichever version you need (you can have a look at this repository's tags to know which is the latest).

Getting a slide show in your fragment/activity

To include a slide show in your layout, simply use the following XML code snippet:

<com.marvinlabs.widget.slideshow.SlideShowView
  android:id="@+id/slideshow"
  android:layout_width="match_parent"
  android:layout_height="match_parent" />

You can then get the SlideShowView using the usual technique:

slideShowView = (SlideShowView) findViewById(R.id.slideshow);

The next step is to create the adapter that will bind your slide data to actual views. This is a process very similar to what you do when working with the ListView widget. In this library, we have a few base adapters to help you create picture slide shows easily from images in your application resources or from images on the Internet. The code would look like that:

adapter = new ResourceBitmapAdapter(this, new int[]{

  R.raw.slide_01, R.raw.slide_02, R.raw.slide_03, R.raw.slide_04
}
);

Once your activity is ready, or inside an event handler like a button click method, you can then start the slideshow:

slideShowView.play();

Customisable components

SlideShowAdapter

This is the key component to bind your slide data with actual view widgets. Have you heard about ListView and Adapter? Well, this is exactly the same concept.

To get you started with picture slide shows, we have created a few useful adapters:

ResourceBitmapAdapter will allow you to show a list of application resource drawables
RemoteBitmapAdapter will allow you to show a list of images that are loaded from the Internet.

We also have a Picasso plugin library. That provides an adapter that works with Picasso instead of AsyncTasks. To use it, simply add the corresponding dependency using gradle:

dependencies {

  compile 'com.marvinlabs:android-slideshow-widget-picasso-plugin:0.4.+@aar' 
}

SlideTransitionFactory

You want something else than just a fade between slides? Simply implement this interface to return whichever view animator you want.

To make it easy for you, we already have a few default implementations that should cover most of your needs:

FadeTransitionFactory if you want your slides to fade out and in
SlideAndZoomTransitionFactory if you want your slides to slide ou left and then zoom in
NoTransitionFactory if you want your slides to brutally show up

PlayList

You want to change the order of your slides? You need your slides to have a variable duration? Well, that's the interface to implement to change that.

To make it easy for you, we already have a few default implementations that should cover most of your needs:

SequentialPlayList will play slides in order with a common default duration
RandomPlayList will play slides in a random order with a common default duration
