我只用了Androidlottie库，字体什么的都没动，可是为什么会出现字体错误呢？

Question

正如标题所说，
我在 Android Studio
上的 Splash Activity 中放置了 lotie 动画但是有一个错误叫做java.lang.RuntimeException: Font asset not found fonts/Microsoft YaHei UI.ttf.

为什么会这样？我没有触及任何 font-related 设置。
如果你知道为什么，请告诉我！
谢谢..

这是我的代码..

activity_splash.xml

<com.airbnb.lottie.LottieAnimationView
        android:id="@+id/lottie_anime"
        android:layout_width="250dp"
        android:layout_height="250dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:lottie_rawRes="@raw/splash_anime" />

飞溅Activity

lottie_anime.playAnimation()

这是错误代码

Answer 1

这不是代码问题，
但是有 .json 动画资源。
这么简单的问题都没找到，好难过

Answer 2

//你可以通过下面的方法做乐蒂动画

//第一步：实现lottie的库

   implementation 'com.airbnb.android:lottie:3.6.0'

//step 2: download the lotie json file form the website link is
  
  https://lottiefiles.com/
//step 3: put the download lotiejson file in your asset folder of android studio

//step 4: put the below code in your xml


    <com.airbnb.lottie.LottieAnimationView
    android:layout_width="match_parent"
    android:layout_height="180dp"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    app:lottie_autoPlay="true"
    app:lottie_fileName="progress1.json"
    app:lottie_loop="true"/>

我只用了Androidlottie库，字体什么的都没动，可是为什么会出现字体错误呢？

I only used the Android lottie library, and I didn't touch anything about the font, but why does the font error appear?

android

kotlin

splash-screen

lottie
