Lottie Animation 在原生 Android 启动画面

Question

Is it possible to load a Lottie animation in the layout of my splash screen?

Currently my splash screen layout is as such:

background.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">

<item android:drawable="@drawable/path_background_gradient" />

<item
    android:drawable="@drawable/ic_locky"
    android:gravity="center" />

</layer-list>

styles.xml

<!-- Splash Launcher UI theme. -->
<style name="Locky.Theme.Launcher" parent="Locky.Theme">
    <item name="android:windowBackground">@drawable/custom_background_launcher</item>
    <item name="colorPrimary">@color/background_gradient_accent_start</item>
    <item name="colorPrimaryDark">@color/background_gradient_accent_start</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

I used this to prevent the white screen on android cold boot.

But instead of the icon ic_locky I want to use a Lottie animation. Is it possible to do so? Because there are many apps that uses an animated logo in the splash screen.

Since there is litte control over WindowManager you can use a static image of your animation in windowbackground and then replace it with the lottie animation.

Lottie:

implementation 'com.airbnb.android:lottie:$lottieVersion'

highest version seems to be 3.4.0 at this time.

And then use the LottieAnimationView to load the animation:

<com.airbnb.lottie.LottieAnimationView
    android:id="@+id/lav_thumbUp"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_marginStart="80dp"
    android:layout_marginTop="8dp"
    android:layout_marginBottom="8dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:lottie_autoPlay="false"
    app:lottie_fileName="thumb_up.json"
    app:lottie_loop="false"
    app:lottie_speed="1.25" />

@Mervin Hemaraju...

I think you ca do so, but, instead of using a drawable, use a custom layout / activity for the splash screen.
