Import

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
        compile 'com.github.Quatja:Vorolay:1.0.1'
}

Usage

Add the view into your layout. You can customize it by using xml attributes

<quatja.com.vorolay.VoronoiView
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:layout_margin="50dp"
  custom:border_color="@color/gray"
  custom:border_round="false"
  custom:border_width="5"    />

Then add your views to the VoronoiView

VoronoiView voronoiView = (VoronoiView) findViewById(R.id.voronoi);
LayoutInflater layoutInflater = getLayoutInflater();
for (int i = 0; i < 15; i++) {
    View view = layoutInflater.inflate(R.layout.item_voronoi, null, false);
    voronoiView.addView(view);
}

Now VoronoiView children will be displayed inside the diagram regions.

Customization

Attributes which you can use in customization purposes

attr	value/example	description
show_border	true	shows or hides each region borders
border_color	#fff	sets all borders color
border_width	5	sets borders width
border_round	true	makes border corners round
generation_type	random	sets different points generation behavior

Generation types

type	description
