我只使用了Android Lottie库，但没有触摸字体，但是为什么会出现字体错误？

编程问答 2022-06-04

问题描述

如标题所示，
我在Android Studio的Splash Activity中放入了洛蒂动画
但是发生了一个名为java.lang.RuntimeException的错误：找不到字体资产fonts / Microsoft YaHei UI.ttf。

为什么会这样呢？我没有触摸任何与字体相关的设置。
如果您知道原因，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" />

SplashActivity 

lottie_anime.playAnimation()

这是错误代码

解决方法

这不是代码的问题，
但带有.json动画资源。
我不敢相信我没有找到这么简单的问题。

,

// 你可以通过下面的方法做lottie动画

//第一步：实现lottie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"/>
