How to slow down the speed of shimmer effect

Question

I have tried the demo of shimmer FrameLayout but it goes very fast and I want to slow down the speed of this effect. How to slow down the speed of shimmer effect and how to use the properties of this library?

Answer 1

You need to use app:shimmer_duration="1500" to set speed of animation in ShimmerFrameLayout

Try this

<com.facebook.shimmer.ShimmerFrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:shimmer_duration="1500">

    <View
        android:layout_width="100dp"
        android:layout_height="8dp"
        android:background="#dddddd" />

</com.facebook.shimmer.ShimmerFrameLayout>

Answer 2

Add app:duration="1500" to shimmer FrameLayout by default its duration is 1000 so to slow down i increase the duration

 <com.facebook.shimmer.ShimmerFrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorAccent"
    app:duration="1500"
    android:id="@+id/shimmer">

  <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textColor="#fff"
      android:layout_gravity="center"
      android:textSize="30dp"
      android:text="Shimmer Effect"/>

</com.facebook.shimmer.ShimmerFrameLayout>

Answer 3

Try defining app:shimmer_duration in XML.

eg app:shimmer_duration="1000"

Answer 4

XML Attr: app:shimmer_duration="" You can do the below programmatically -

  val builder = Shimmer.AlphaHighlightBuilder()
  builder.setDuration(500L)
  shimmerFrame.setShimmer(builder.build())
