[移动开发]Lottie动画多动图切换遇到的坑

问题原因是多动图json文件切换动图效果变成静态图。

布局：

<com.airbnb.lottie.LottieAnimationView
    android:id="@+id/lottieAnimView"
    android:layout_width="@dimen/box_size_80"
    android:layout_height="@dimen/box_size_80"
    android:layout_gravity="center"
    android:layout_margin="@dimen/layout_padding"
    app:lottie_autoPlay="false"
    app:lottie_loop="true" />

Dialog:

public class PermissionLoadingDialog extends Dialog implements DialogInterface.OnDismissListener {
