ShimmerLayout can be used to add shimmer effect (like the one used at Facebook or at LinkedIn) to your Android application. Beside memory efficiency even animating a big layout, you can customize the behaviour and look of the animation. Check out the wiki for attributes!

When it comes to performance, ShimmerLayout is the best option available. Not only can you achieve high frame rate even in RecyclerViews, but it also animates views with insignificant memory footprint.

I conducted a benchmark to compare memory usages between different shimmer implementations. The test device I used is a HTC M8 phone. For the animations the sample application was used.

Library used	Android Profiler result

implementation 'io.supercharge:shimmerlayout:2.1.0'

Create the layout on which you want to apply the effect and add as a child of a ShimmerLayout

<io.supercharge.shimmerlayout.ShimmerLayout
        android:id="@+id/shimmer_text"
        android:layout_width="wrap_content"
        android:layout_height="40dp"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="50dp"
        android:paddingLeft="30dp"
        android:paddingRight="30dp"
        app:shimmer_animation_duration="1200">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:gravity="center"
            android:text="ShimmerLayout"
            android:textColor="@color/shimmer_background_color"
            android:textSize="26sp"/>
    </io.supercharge.shimmerlayout.ShimmerLayout>

Last, but not least you have to start it from your Java code

ShimmerLayout shimmerText = (ShimmerLayout) findViewById(R.id.shimmer_text);
shimmerText.startShimmerAnimation();
