Question

当我尝试将gif加载到项目中时，突然返回我错误：

Java.Lang.IllegalStateException: 'Unable to parse composition'

我想在我试图使用Lottie和Json File的项目中插入gif

到目前为止我的代码

<forms:AnimationView 
    x:Name="animationView" 
    Grid.Row="1"
    Animation="first.json" 
    Loop="false" 
    AutoPlay="false"/>

Answer 1

请在您的XAML头中添加xmlns:lottie="clr-namespace:Lottie.Forms;assembly=Lottie.Forms"并使用此组件

 <lottie:AnimationView 
                x:Name="AnimationView" 
                Animation="first.json" 
                AutoPlay="True" Loop="true"
                VerticalOptions="FillAndExpand"
                HorizontalOptions="FillAndExpand" />

也不要忘记在MainActivity和AppDelegate上初始化AnimationViewRenderer.Init();

I also encountered the same problem, but I couldn't find the AnimationViewRenderer class in my code to initialize it

Answer 3

需要确定json

Android：DroidProject/Assets/filename.json类似于AndroidAsset

iOS：iOSProject/filename.json就像BundleResource

Answer 4

就我而言，我用 app:lottie_url 替换了 app:lottie_rawRes ，效果很好

Lottie错误：“ Java.Lang.IllegalStateException：'无法解析组成''
