Lottie 错误：“java.lang.IllegalStateException：无法解析组合”

Question

我试图将 LottieAnimationView 添加到项目中的 xml 布局中，但出现此异常：“java.lang.IllegalStateException：无法解析组合”。

XML 布局的一部分：

\n

    <com.airbnb.lottie.LottieAnimationView\n    android:id="@+id/animationView"\n    android:layout_width="50dp"\n    android:layout_height="50dp"\n    app:layout_constraintBottom_toBottomOf="parent"\n    app:layout_constraintEnd_toEndOf="parent"\n    app:layout_constraintStart_toStartOf="parent"\n    app:layout_constraintTop_toTopOf="parent"\n    app:lottie_autoPlay="true"\n    app:lottie_loop="true"\n    app:lottie_rawRes="@raw/heart_beat" />\n

\n

有趣的是，当我创建一个新的测试项目并将上述代码粘贴到新创建的 Activity_main.xml 时，一切都在新项目中完美运行。

\n

我尝试app:lottie_rawRes="@raw/heart_beat"用app:lottie_fileName="heart_beat.json"（从资产文件夹）替换，但仍然没有结果。\n我该如何解决此问题？谢谢。

如果你只是想避免崩溃，你可以在设置动画之前设置lottie失败监听器而不是默认监听器。

lottieView.setFailureListener { t ->
    //do on error
}
lottieView.setAnimation(...)
