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

attrvalue/exampledescriptionshow_bordertrueshows or hides each region bordersborder_color#fffsets all borders colorborder_width5sets borders widthborder_roundtruemakes border corners roundgeneration_typerandomsets different points generation behavior

Generation types

typedescriptionrandomVoronoiView generates a random point positions inside the view bounds.orderedpoints are placed like a table - rows and columns.custompoints will be placed in user defined positions.

These attributes are available programmatically too.
