+# Android 3D Carousel
 
-An Android 3D Carousel
+A simple 3D carousel you can integrate into your Android app.
+
+This version of the library has no additional dependencies, but requires Android
+v9+ to work.
+
+Based on the Android 3D Carousel by 
+Igor Kushnarev and available on Code Project : http://www.codeproject.com/Articles/146145/Android-D-Carousel
+
+![Sample app screenshot](https://raw.github.com/ludovicroland/carousel-android/master/screenshot1.png)
+
+## Usage
+
+For a full example see the `sample` app in the
+[repository](https://github.com/ludovicroland/carousel-android/tree/master/sample).
+
+### From Maven Central
+
+Library releases are available on Maven Central
+
+**Gradle**
+
+```groovy
+compile 'fr.rolandl:carousel:1.0.0@aar'
+```
+
+**Maven**
+
+```xml
+<dependency>
+  <groupId>fr.rolandl</groupId>
+  <artifactId>carousel</artifactId>
+  <version>1.0.0</version>
+  <type>aar</type>
+</dependency>
+```
+
+### As Library Project
+
+Alternatively, check out this repository and add it as a library project.
+
+```console
+$ git clone https://github.com/ludovicroland/carousel-android.git
+```
+
+Import the project into your favorite IDE and add
+`android.library.reference.1=/path/to/carousel-android/library` to your
+`project.properties`.
+
+### Layout
+
+You need to declare the `Carousel` directly into your layout.
+
+```xml
+<fr.rolandl.carousel.Carousel
+  xmlns:android="http://schemas.android.com/apk/res/android"
+  android:id="@+id/carousel"
+  android:layout_width="match_parent"
+  android:layout_height="match_parent"
+  android:animationDuration="200"
+/>
+```
+
+### Items
+
+An item should be associated with a business object (a classical pojo), for example:
+
+```java
+public final class Photo
+    implements Serializable
+{
+
+  private static final long serialVersionUID = 1L;
+
+  public final String name;
+
+  public final String image;
+
+  public Photo(String name, String image)
+  {
+    this.name = name;
+    this.image = image;
+  }
+
+}
+```
+
+with a specific layout, for example:
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<LinearLayout
+  xmlns:android="http://schemas.android.com/apk/res/android"
+  android:orientation="vertical"
+  android:layout_width="match_parent"
+  android:layout_height="match_parent"
+>
+  <ImageView
+    android:id="@+id/image"
+    android:layout_width="100dip"
+    android:layout_height="100dip"
+    android:scaleType="centerCrop"
+  />
+
+  <TextView
+    android:id="@+id/name"
+    android:layout_width="wrap_content"
+    android:layout_height="wrap_content"
+    android:textColor="@android:color/black"
+  />
+</LinearLayout>
+```
+
+and with a CarouselItem that should override the `extractView` and `update` methods :
+
+```java
+public final class PhotoItem
+      extends CarouselItem<Photo>
+  {
+
+    private ImageView image;
+
+    private TextView name;
+
+    private Context context;
+
+    public PhotoItem(Context context)
+    {
+      super(context, R.layout.item);
+      this.context = context;
+    }
+
+    @Override
+    public void extractView(View view)
+    {
+      image = (ImageView) view.findViewById(R.id.image);
+      name = (TextView) view.findViewById(R.id.name);
+    }
+
+    @Override
+    public void update(Photo photo)
+    {
+      image.setImageResource(getResources().getIdentifier(photo.image, "drawable", context.getPackageName()));
+      name.setText(photo.name);
+    }
+
+  }
+```
+
+### Adapter
+
+You also have to create your own adapter that takes a list of business object in its constructor:
+
+```java
+public final class MyAdapter
+    extends CarouselAdapter<Photo>
+{
+
+  public MyAdapter(Context context, List<Photo> photos)
+  {
+    super(context, photos);
+  }
+
+  @Override
+  public CarouselItem<Photo> getCarouselItem(Context context)
+  {
+    return new PhotoItem(context);
+  }
+
+}
+```
+
+### In the Activity/Fragment
+
+In the activity or the fragment that uses the carousel, you can find its reference:
+
+```java
+final Carousel carousel; = (Carousel) findViewById(R.id.carousel);
+```
+
+create your list of business objects:
+
+```java
+final List<Photo> photos = new ArrayList<>();
+photos.add(new Photo("Photo1", "fotolia_40649376"));
+photos.add(new Photo("Photo2", "fotolia_40973414"));
+photos.add(new Photo("Photo3", "fotolia_48275073"));
+photos.add(new Photo("Photo4", "fotolia_50806609"));
+photos.add(new Photo("Photo5", "fotolia_61643329"));
+```
+
+create an instance of your adapter:
+
+```java
+final CarouselAdapter adapter = adapter = new MyAdapter(this, photos);
+carousel.setAdapter(adapter);
+adapter.notifyDataSetChanged();
+```
+
+### Listeners
+
+You can also use some listeners on the carousel.
+
+The `OnItemClickListener`:
+
+```java
+carousel.setOnItemClickListener(new OnItemClickListener()
+{
+
+  @Override
+  public void onItemClick(CarouselBaseAdapter<?> carouselBaseAdapter, View view, int position, long id)
+  {
+    Toast.makeText(getApplicationContext(), "The item '" + position + "' has been clicked", Toast.LENGTH_SHORT).show();
+    carousel.scrollToChild(position);
+  }
+  
+});
+```
+
+The `OnItemLongClickListener`:
+
+```java
+carousel.setOnItemLongClickListener(new OnItemLongClickListener()
+{
+
+  @Override
+  public boolean onItemLongClick(CarouselBaseAdapter<?> carouselBaseAdapter, View view, int position, long id)
+  {
+    Toast.makeText(getApplicationContext(), "The item '" + position + "' has been long clicked", Toast.LENGTH_SHORT).show();
+    carousel.scrollToChild(position);
+    return false;
+  }
+  
+});
+```
