BubbleGum was designed to quickly apply gradients into different UI elements of an android app. The overhead and performance impact is minimal, as BubbleGum is based on Android drawables.

• Apply gradient to a view with an animation effect or transition between 2 gradients.
• Created an animated view with a set of gradients that interchange at the specified amount of time.
• It applies a vignetting effect over the gradient to enhance the view. (will become optional in the future)
• Control gradient angle
• Apply the gradient colors at custom positions. If custom positions are not specified, they will be distributed equally.

Or give it a try with the sample app: https://play.google.com/store/apps/details?id=com.hold1.bubblegum

Add the following line in your build.gradle file

implementation 'com.hold1:bubblegum:0.0.1'

BubbleGum can be used in 3 ways, depending of your needs:

    <com.hold1.bubblegum.BubbleView
        android:id="@+id/headerBackground"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:bbStartColor="@color/demoStartColor"
        app:bbEndColor="@color/demoEndColor"
        app:bbAngle="45"/>

You can always change the applied gradient of a BubbleView programatically. Please refer to SlideFragment in Demo app.

    val g1 = Gradient(intArrayOf(Color.RED, Color.GREEN))
    val g2 = Gradient(intArrayOf(Color.DKGRAY, Color.BLUE))
    val g3 = Gradient(intArrayOf(Color.CYAN, Color.MAGENTA))
    
    val animation = GradientDrawable(arrayOf(g2, g1, g3))
    baseView.background = animation
        
    animation.start()

    BubbleBuilder()
            .withStartColor(Color.RED)
            .withEndColor(Color.BLUE)
            .withAngle(35)
            .intoView(exampleView)
