Shimmer-android is an Android port of Facebook Shimmer library for iOS.

Examples of usage:

• show a loading indicator
• show a highlighted TextView.

Gradle dependency:

compile 'com.romainpiel.shimmer:library:1.2.0@aar'

Add a ShimmerTextView to your layout:

<com.romainpiel.shimmer.ShimmerTextView
    android:id="@+id/shimmer_tv"
    android:text="@string/shimmer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#444"
    android:textSize="50sp"/>

To start the animation:

shimmer = new Shimmer();
shimmer.start(myShimmerTextView);

You may want to keep track of the shimmer instance after the animation is started if you want to stop it.

To stop it:

shimmer.cancel();

You can change the color of the reflection using the custom attribute reflectionColor:

<com.romainpiel.shimmer.ShimmerTextView
    android:id="@+id/shimmer_tv"
    android:text="@string/shimmer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#444"
    android:textSize="50sp"
    app:reflectionColor="#f00"/>

The animation can be tweaked like a usual ObjectAnimator:

// DON'T COPY THIS CODE TO YOUR PROJECT! It is just an example
shimmer.setRepeatCount(0)
    .setDuration(500)
    .setStartDelay(300)
    .setDirection(Shimmer.ANIMATION_DIRECTION_RTL)
    .setAnimatorListener(new Animator.AnimatorListener(){});

Shimmer also includes a ShimmerButton. It works exactly the same way as a ShimmerTextView. Have a look at how it's implemented and you can apply the same effect on your custom view if you need it.

See the sample for a common use of this library.
