Question

我正在制作一个RN 0.50.1的跟踪应用程序，并使用react-native-maps在MapView.Marker＆＃34; image＆＃34;上自定义图像的地图上显示用户位置。道具。

该位置工作正常，跟踪工作正常，但问题是标记从一个坐标跳到另一个坐标长期变化。尝试使用MapView.AnimatedRegion设置状态并使用计时方法更新坐标，但没有运气。也使用https://github.com/airbnb/react-native-maps/blob/master/example/examples/AnimatedMarkers.js示例，但仍然没有运气解释使用Animated.Region，但它给了我Animated.Region的错误不是构造函数。

我需要在长时间更换时平稳移动标记。

我的Package.JSON文件 -

"version": "0.0.1",
"private": true,
"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",

}

}

任何帮助表示赞赏。请。

我想你想看看MapView methods（例如animateToCoordinates）。
