Shimmerfy

🚀A Jetpack Compose utility library for
Made with ❤️ for Android Developers and Composers

💡Introduction

Shimmerfy is a lightweight library for Jetpack Compose that enables you to effortlessly integrate shimmer loading effects into your UI components. Enhance your app's user experience with smooth and appealing loading animations using Shimmerfy.

🚀 Implementation

You can check /app directory which includes example application for demonstration.

Gradle setup

In build.gradle of app module, include this dependency

dependencies {
    implementation ("com.github.tusharhow:Shimmerfy:1.0.5")
}

You can find latest version and changelogs in the releases.

Usage

1. Initialize Shimmer Animation in your Composable function:

LazyColumn {
  items(6) {
    // design your content skeleton with shimmerfy

  }
 }

2. Create a ShimmerItemRow

Row(){
     ShimmerSkeleton(
        modifier = Modifier
            .width(100.dp)
            .height(100.dp)
            .clip(RoundedCornerShape(8)),
    )
}

3. Dummy card

For the idea i've created a dummy shimmer card.

// Example: Created a dummy shimmer card
Row(
    modifier = Modifier
        .padding(16.dp),
) {
    ShimmerSkeleton(
        modifier = Modifier
            .width(100.dp)
            .height(100.dp)
            .clip(RoundedCornerShape(8)),
    )
    Spacer(modifier = Modifier.width(16.dp))
    Column {
        ShimmerSkeleton(
            modifier = Modifier
                .width(200.dp)
                .height(20.dp),
        )
        Spacer(modifier = Modifier.height(16.dp))
        ShimmerSkeleton(
            modifier = Modifier
                .width(100.dp)
                .height(20.dp),
        )
        Spacer(modifier = Modifier.height(8.dp))
        ShimmerSkeleton(
            modifier = Modifier
                .width(150.dp)
                .height(20.dp),
        )
    }
}

ShimmerSkeleton with Customization

The ShimmerSkeleton composable now supports additional customization options:

• Shimmer Colors: You can set custom shimmer colors using the shimmerColors parameter. For example:

  shimmerColors = listOf(
      Color.LightGray.copy(0.9f),
      Color.LightGray.copy(0.2f),
      Color.LightGray.copy(0.9f)
  )

• Easing Function: Customize the easing function for the shimmer animation using the easing parameter. For example:

  easing = EaseIn

• Animation Duration: Adjust the duration of the shimmer animation with the duration parameter (in milliseconds). For example:

  duration = 1200

• Repeat Mode: Set the repeat mode for the shimmer animation using the repeatMode parameter. For example:

  repeatMode = RepeatMode.Reverse

Example Usage

@Composable
fun ShimmerItem(modifier: Modifier) {
    ShimmerSkeleton(
        modifier = modifier,
        shimmerColors = listOf(
            Color.LightGray.copy(0.9f),
            Color.LightGray.copy(0.2f),
            Color.LightGray.copy(0.9f)
        ),
        easing = EaseIn,
        duration = 1200,
        repeatMode = RepeatMode.Reverse
    )
}
