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 |
