Shimmer Effect on Image in Android

The Shimmer effect is a popular way to indicate content loading in many applications. Facebook, for instance, uses this effect in its app. It gives the appearance of a gradient light moving over content placeholders, creating a "shimmering" visual effect.

For Android, Facebook provides a library called Shimmer for this effect. Here's how to use it:

1. Add Shimmer dependency:

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

dependencies {
    implementation 'com.facebook.shimmer:shimmer:0.5.0'  // Verify the latest version on Maven Central or JitPack.
}

2. Wrap the content with `ShimmerFrameLayout`:

In your XML layout, wrap the content for which you want to show the Shimmer effect with ShimmerFrameLayout.

<com.facebook.shimmer.ShimmerFrameLayout
    android:id="@+id/shimmer_view_container"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    shimmer:shimmer_colored="true">

    <!-- Your image or content placeholder here -->
    <ImageView
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:src="@drawable/your_image_placeholder" />

</com.facebook.shimmer.ShimmerFrameLayout>

3. Start and stop the Shimmer effect:

In your activity or fragment:

val shimmerFrameLayout = findViewById<ShimmerFrameLayout>(R.id.shimmer_view_container)

// Start the Shimmer effect
shimmerFrameLayout.startShimmer()

// Stop the Shimmer effect when content is loaded
// shimmerFrameLayout.stopShimmer()

4. Customize the Shimmer:

Shimmer provides various attributes to customize the effect:

shimmer_colored: Whether the shimmering mask should be tinted.
shimmer_base_color: The shimmer base color.
shimmer_highlight_color: The shimmer highlight color.
shimmer_duration: The time it takes in milliseconds for the shimmering animation to do one full sweep of the layout.

... and many more. Check the official documentation for a complete list of attributes.

Note:

Shimmer should ideally be used as a temporary placeholder. Once your content (like image or text) is loaded, you should stop the shimmer and replace the placeholder with the actual content.
Overusing the Shimmer effect can be distracting to users, so it's a good idea to use it judiciously.
