java - 洛蒂错误 : "java.lang.IllegalStateException: Unable to parse composition"

Question

我正在尝试将 LottieAnimationView 添加到我的项目中的 xml 布局中，但出现此异常:“java.lang.IllegalStateException: Unable to parse composition”。

部分 XML 布局:

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

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

我尝试将 app:lottie_rawRes="@raw/heart_beat" 替换为 app:lottie_fileName="heart_beat.json"(来自 assets 文件夹)，但仍然没有结果.我该如何解决这个问题？谢谢。

如果你只想避免崩溃，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(...)
