AndroidVeil
An easy, flexible way to implement veil skeletons and shimmering effect for Android.
Download
Gradle
Add the codes below to your root build.gradle file (not your module build.gradle file):
allprojects {
repositories {
mavenCentral()
}
}And add the dependency below to your module's build.gradle file:
dependencies {
implementation "com.github.skydoves:androidveil:1.1.3"
}Usage
First, add following XML namespace inside your XML layout file:
xmlns:app="http://schemas.android.com/apk/res-auto"VeilLayout in layout
<com.skydoves.androidveil.VeilLayout
android:id="@+id/veilLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:veilLayout_veiled="true" // shows veils initially
app:veilLayout_shimmerEnable="true" // sets shimmer enable
app:veilLayout_baseColor="@android:color/holo_green_dark" // sets shimmer base color
app:veilLayout_highlightColor="@android:color/holo_green_light" // sets shimmer highlight color
app:veilLayout_baseAlpha="0.6" // sets shimmer base alpha value
app:veilLayout_highlightAlpha="1.0" // sets shimmer highlight alpha value
app:veilLayout_dropOff="0.5"// sets how quickly the shimmer`s gradient drops-off
app:veilLayout_radius="6dp" // sets a corner radius of the whole veiled items >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="And now here is my secret, a very simple secret"
android:textColor="@android:color/white"
android:textSize="22sp"/>

</com.skydoves.androidveil.VeilLayout>Veil and UnVeil
We can implement veiled skeletons using below methods.
veilLayout.veil()
veilLayout.unVeil()Implement veils using layout resource
We can implement veiled skeletons using the layout resource.
veilLayout.layout = R.layout.layout_item_testVeilRecyclerFrameView
VeilRecyclerFrameView implements veiled skeletons for RecyclerView with the shimmer effect.
VeilRecyclerFrameView in layout
<com.skydoves.androidveil.VeilRecyclerFrameView
android:id="@+id/veilRecyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:veilFrame_layout="@layout/item_profile" // sets to make veiling target layout
app:veilFrame_veiled="true" // shows veils initially
app:veilFrame_shimmerEnable="true" // sets shimmer enable
app:veilFrame_baseColor="@android:color/holo_green_dark" // sets shimmer base color
app:veilFrame_highlightColor="@android:color/holo_green_light" // sets shimmer highlight color
app:veilFrame_baseAlpha="0.6" // sets shimmer base alpha value
app:veilFrame_highlightAlpha="1.0" // sets shimmer highlight alpha value
app:veilFrame_radius="8dp" // sets a corner radius of the whole veiled items
app:veilFrame_isItemWrapContentHeight="true" // sets height of list item wrap_content
app:veilFrame_isItemWrapContentWidth="true" // sets width of list item wrap_content />And we should attach our own adapter and LayoutManager.
veilRecyclerView.setAdapter(adapter) // sets your own adapter
veilRecyclerView.setLayoutManager(LinearLayoutManager(this)) // sets LayoutManager
veilRecyclerView.addVeiledItems(15) // add veiled 15 itemsVeil and UnVeil
We can implement veiled skeletons using below methods.
veilRecyclerView.veil() // shows veil skeletons
veilRecyclerView.unVeil() // disappear veils and shows your own recyclerViewRecyclerView
We can access our Recyclerview and veiledRecyclerView using the below methods.
veilRecyclerView.getRecyclerView() // veilRecyclerView.getRecyclerView().setHasFixedSize(true)
veilRecyclerView.getVeiledRecyclerView()Shimmer
This library using shimmer-android by Facebook.
Here are the detail shimmer-instruction about shimmer or you can reference below examples.
create using Builder
This is how to create Shimmer's instance using Shimmer.Builder class.
val shimmer = Shimmer.ColorHighlightBuilder()
.setBaseColor(ContextCompat.getColor(context, R.color.shimmerBase0))
.setHighlightColor(ContextCompat.getColor(context, R.color.shimmerHighlight0))
.setBaseAlpha(1f)
.setHighlightAlpha(1f)
.build()
veilLayout.shimmer = shimmer // sets shimmer to VeilLayout
veilRecyclerView.shimmer = shimmer // sets shimmer to VeilRecyclerViewcreate using kotlin dsl
This is how to create Shimmer's instance using kotlin dsl.
val shimmer_alpha = alphaShimmer {
setBaseAlpha(1.0f)
setHighlightAlpha(0.5f)
}
val shimmer_color = colorShimmer {
setBaseAlpha(1.0f)
setHighlightAlpha(0.5f)
setBaseColor(ContextCompat.getColor(context, R.color.colorPrimary))
setHighlightColor(ContextCompat.getColor(context, R.color.colorPrimaryDark))
