Easy Slide Show 4 Android
Still in progress

A small library ( it is actually one file ) that you can basically copy and paste it in your project. It uses picasso to download images from urls and cache them. It handles right to left and left to right gestures by default with changing to next or previous image respectively. It uses dots to indicate which image you are using.

Better explained with a ScreenShot

##Changes

1. Add it in your layout

    <gr.spiritinlife.EasySlideShow.SlideShowView
             android:id="@+id/slideShow"
             android:layout_width="match_parent"
             android:layout_height="170dp"
             android:scaleType="centerCrop"
             slideshow:dotNormal="#626283"
             slideshow:dotSelected="#62aa83"
             slideshow:dotRadius="5dp"
             slideshow:dotMargin="2dp"/>

2. Get it from code

    slideShow = (SlideShowView) view.findViewById(R.id.slideShow);

3. Start it passing it an array of urls

    slideShow.start(urls);

Example activity

public class EasySlideShowActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.easyslideshow_activity);

    SlideShowView slideShow  = (SlideShowView) findViewById(R.id.slideShow);
    slideShow.start(new String[] {
        "http://7-themes.com/data_images/out/42/6914793-tropical-beach-images.jpg",
        "http://p1.pichost.me/i/51/1749517.jpg",

    });
  }
}

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:slideshow="http://schemas.android.com/apk/res-auto"
                android:orientation="vertical"
                android:layout_width="match_parent"
                android:layout_height="match_parent">


    <gr.spiritinlife.EasySlideShow.SlideShowView
            android:id="@+id/slideShow"
            android:layout_width="match_parent"
            android:layout_height="170dp"
            android:scaleType="centerCrop"
            slideshow:dotNormal="#626283"
            slideshow:dotSelected="#62aa83"
            slideshow:dotRadius="5dp"
            slideshow:dotMargin="2dp"
            android:layout_centerInParent="true"/>
