Nox

Nox is an Android library created to show a custom view with some images or drawables (NoxItem instances) inside which are drawn following a shape indicated by the library user. You can create you own Shape implementations if you want, by default there are some interesting Shape implementations to show NoxItem instances following a circular, spiral or linear shape. The space needed to show you NoxItem instances will be calculated automatically by the library and the scroll effect will be enabled if needed. If the Shape you choose needs a bidirectional scroll, like CircularShape, this will be enabled automatically.

Usage

To use Nox inside your layouts you have to follow this steps:

• 1 - Add a NoxView widget to your layout:

  <com.github.pedrovgs.nox.NoxView
      xmlns:nox="http://schemas.android.com/apk/res-auto"
      android:id="@+id/nox_view"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      nox:item_size="@dimen/nox_item_size"
      nox:item_margin="@dimen/nox_item_margin"
      nox:item_placeholder="@drawable/nox_item_placeholder"
      nox:shape="circular_shape"/>

• 2 - Provide different configurations based on styleable attributes:

• NoxItem size: nox:item_size

• NoxItem margin: nox:item_margin

• NoxItem placeholder: nox:item_placeholder. This placeholder will be used if the NoxItem to draw has no a placeholder configured.

• Use circular transformation: nox:use_circular_transformation. Applies a Picasso circular transformation to the resource loaded.

• Shape used: nox:shape. Review attrs.xml file to know the list of shapes ready to be used in the library.

This configuration can be also provided programmatically. Take a look to the sample project to find some samples.

• 3 - Create a List and invoke the method showNoxItems in your NoxView instance:

  List<NoxItem> noxItems = new ArrayList<NoxItem>();
  noxItems.add(new NoxItem("http://api.randomuser.me/portraits/thumb/1.jpg"));
  noxView.showNoxItems(noxItems);

If you've added a new NoxItem to your list and you want to redraw your NoxView you can use notifyDataSetChanged method:

   noxView.notifyDataSetChanged();
   

If you are going to download any resource from internet remember to add the internet permission to your AndroidManifest.

To be able to configure a custom Shape implementation review MainActivity class.

Add it to your project

Add Nox dependency to your build.gradle

dependencies{
    compile 'com.github.pedrovgs:nox:1.0'
}

Or add Nox as a new dependency inside your pom.xml

<dependency>
    <groupId>com.github.pedrovgs</groupId>
    <artifactId>nox</artifactId>
    <version>1.0</version>
    <type>aar</type>
</dependency>
