ShimmerLayout in Android with Examples

ShimmerLayout is an alternative to Facebook's Shimmer library for Android. It's created by the team behind the Supercharge open-source initiative. The library helps achieve a shimmering effect, typically used as a content placeholder before the actual content gets loaded.

Here's a step-by-step guide on how to use ShimmerLayout in your Android project:

1. Add the dependency:

Firstly, add the ShimmerLayout library dependency to your app's build.gradle:

dependencies {
    implementation 'io.supercharge:shimmerlayout:2.1.0'  // Verify the latest version on Maven Central or JitPack.
}

2. Use `ShimmerLayout` in your XML:

Incorporate ShimmerLayout in your XML layout, wrapping around the views you want the shimmer effect to be applied to:

<io.supercharge.shimmerlayout.ShimmerLayout
    android:id="@+id/shimmer_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:shimmer_animation_duration="1500"
    app:shimmer_color="#f2f2f2">

    <!-- Your views or content placeholder goes here. For instance: -->
    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:background="@android:color/darker_gray" />
    
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@android:color/darker_gray" />

</io.supercharge.shimmerlayout.ShimmerLayout>

3. Start and stop the shimmer animation:

In your activity or fragment:

val shimmerLayout = findViewById<ShimmerLayout>(R.id.shimmer_layout)

// Start the shimmer animation
shimmerLayout.startShimmerAnimation()

// When you want to stop the shimmer, usually after content is loaded:
// shimmerLayout.stopShimmerAnimation()

4. Customize the `ShimmerLayout`:

ShimmerLayout provides several attributes to customize its appearance and behavior:

shimmer_animation_duration: The time it takes in milliseconds for the shimmer animation to run once.
shimmer_color: The color of the shimmer.
shimmer_auto_start: Whether the shimmering animation should automatically start.

... and more. Check out the library's GitHub page or documentation for more customization options.

Tips:

It's a good practice to stop the shimmer effect as soon as your actual content is available. Running shimmer animations can consume unnecessary resources if left running indefinitely.
As with any animation, use the shimmer effect judiciously. Overuse can be distracting for the user.

Remember, the primary purpose of shimmer effects is to indicate that content is currently loading, providing the user with a more interactive and engaging loading state compared to static placeholders.
