Draw animated stars on Android view canvas

AnimatedStarsView for Android

Kotlin Android view that draws animated stars on a canvas.

Quick Start Guide

Step 1

Add library to your gradle module

repositories {
    maven { url "http://dl.bintray.com/sofakingforever/libraries" }
}

dependencies {
    implementation 'com.sofakingforever.libraries:stars:1.1.3@aar'

    // Don't forget to add kotlin if you're in a pure-java project (thanks to moisoni97)
    implementation 'org.jetbrains.kotlin:kotlin-stdlib:1.2.71
}

Step 2

Insert View via XML (or code)

    <com.sofakingforever.stars.AnimatedStarsView
        android:id="@+id/stars"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:starsView_bigStarThreshold="10dp"
        app:starsView_meteoritesColors="@array/meteorites_colors"
        app:starsView_meteoritesEnabled="true"
        app:starsView_meteoritesInterval="2000"
        app:starsView_maxStarSize="16dp"
        app:starsView_minStarSize="1dp"
        app:starsView_starColors="@array/star_colors"
        app:starsView_starCount="50" />

Step 3

Add the color array

    <integer-array name="star_colors_small">
        <!-- This is how you can configure the ratio of star colors-->
        <item>@color/star_color_1</item>
        <item>@color/star_color_1</item>
        <item>@color/star_color_1</item>
        <item>@color/star_color_1</item>
        <item>@color/star_color_2</item>
        <item>@color/star_color_3</item>
    </integer-array>


    <integer-array name="meteorites_colors">

        <item>@color/star_color_2</item>
        <item>@color/star_color_4</item>
        <item>@color/star_color_3</item>
    </integer-array>

Step 4

Kotlin Implementation Example - Call onStart and onStop

    override fun onStart() {
        super.onStart()
        stars.onStart()
    }

    override fun onStop() {
        stars.onStop()
        super.onStop()
    }

DONE!
