问题：Flutter封装Android原生插件时KLivenessView对齐异常

我正在为Flutter封装一款Android原生插件，严格遵循Flutter官方文档完成实现：通过原生端的PlatformView和Flutter端的AndroidView组件展示Android原生UI。TextView、WebView等常规原生视图显示正常，但插件提供的KLivenessView（需在黄色圆圈内展示相机流）出现对齐异常，该插件在其他Android原生项目中运行正常。

原生端代码片段

class FlutterWebView internal constructor(
    context: Context,
    messenger: BinaryMessenger,
    id: Int,
    activity: Activity
) :
    PlatformView,KLivenessCallbacks, MethodCallHandler, AppCompatActivity() {
    val activity=activity
    val context=context
    private val kLivenessView: KLivenessView
    private  var methodChannel: MethodChannel
    override fun getView(): View {
        return kLivenessView//this is the object of UI class provided by plugin
    }

    init {
        
        kLivenessView = KLivenessView(context)
    }
}
