Question

我正在尝试使用需要上下文实例化UI对象的本机映射库，如何传递它？

原生函数是android.view.View的扩展，其所需的参数是上下文。

Ref：https://developers.arcgis.com/android/latest/api-reference/reference/com/esri/arcgisruntime/mapping/view/MapView.html#MapView(android.content.Context)

Example.vue：

<template>
    <Page class="page">
        <StackLayout>
            <Placeholder @creatingView="creatingView"/>
         </StackLayout>
    </Page>
</template>

<script>
    export default {
        methods: {
            creatingView(args){
                //This is where I need the context as a parameter
                const nativeView = new com.esri.arcgisruntime.mapping.view.MapView(this.context);
                args.view = nativeView;                    
            }
        }
    };
</script>

Answer 1

无论使用哪种样式/框架，都可以使用以下应用程序上下文

import * as application from "application";

const context = application.android.context;

Answer 2

您可以从createdView事件args获取当前的android上下文。

methods: {
       creatingView(args){
           const nativeView = new com.esri.arcgisruntime.mapping.view.MapView(args.context);
           args.view = nativeView;                    
       }
}

NativeScript使用Vue获取当前的android上下文？
