🏅An easy way to implement medal effect for Android.

Download

Gradle

Add below codes to your root build.gradle file (not your module build.gradle file).

allprojects {
    repositories {
        jcenter()
    }
}

And add a dependency code to your module's build.gradle file.

dependencies {
    implementation "com.github.skydoves:medal:1.0.4"
}

Usage

Add following XML namespace inside your XML layout file.

xmlns:app="http://schemas.android.com/apk/res-auto"

MedalLayout in layout

<com.skydoves.medal.MedalLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    app:direction="right"
    app:turn="1"
    app:speed="1500">

    <ImageView
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:src="@drawable/medal2"
        android:layout_centerInParent="true"
        android:scaleType="fitXY"/>

</com.skydoves.medal.MedalLayout>

create using builder

This is how to create MedalAnimation's instance using MedalAnimation.Builder class.

MedalAnimation medalAnimation = new MedalAnimation.Builder()
     .setDirection(MedalDirection.RIGHT)
     .setDegreeX(360)
     .setDegreeZ(360)
     .setSpeed(4200)
     .setTurn(4)
     .setLoop(10)
     .build();

create using kotlin dsl

This is how to create MedalAnimation's instance using kotlin dsl.

val medalAnimation = medalAnimation {
     direction = MedalDirection.LEFT
     speed = 4200
     turn = 4
}

start animation

There are a few ways to start the medal animation.

medalAnimation.startAnimation(targetView);
medalLayout.startAnimation(targetView);

or we can give a medal effect using view's startAnimation method.
