如何使用快应用内置地图查看、导航位置

使用快应用内置地图查看、导航位置。仅限中国大陆使用，需要获取设备定位权限。

chooseLocation  可以选择地理位置，也可以搜索位置，确定选择的位置后会返回一个经纬度坐标，然后使用 openLocation 进行导航。

导航app中默认显示滴滴出行快应用，百度地图和高德地图如果手机安装了才会显示。

使用方法（此处以deeplink跳转为例）：

router.push({
  uri: 'pages/openLocation',  
  params: {    
  name: '故宫',    
  address: '北京市东城区景山街前街4号',    
  scale: 17,    
  latitude:116.397067,    
  longitude:39.917399  
  }})

　　

快应用ux页面实现：

1. 首先写好页面的布局模板，展示一个地图，一个地址展示栏，一个导航按钮，一个我的位置控制组件，代码如下：

<template>
  <div class="container">
    <div class="page-title-wrap">
      <text class="page-title">{{componentName}}</text>
    </div>

    <div class="item-container">
      <div class="item-container">
        <div class="item-content">
          <text>{{$t('message.interface.system.geolocation.deviceInfo')}}</text>
          <text>{{deviceInfo}}</text>
          <text>{{$t('message.interface.system.geolocation.isHuawei')}}{{isHuawei}}</text>
        </div>
        <input type="button" class="btn" onclick="getDeviceInfo"
          value="{{$t('message.interface.system.geolocation.getDeviceInfo')}}" />
      </div>


      <div class="item-content">
        <text class="txt">{{$t('message.interface.system.geolocation.getGeolocation')}}</text>
        <text class="txt">latitude: {{geolocationGetData.latitude}}</text>
        <text class="txt">longitude: {{geolocationGetData.longitude}}</text>
        <text class="txt">altitude: {{geolocationGetData.altitude}}</text>
        <text class="txt">accuracy: {{geolocationGetData.accuracy}}</text>
        <text class="txt">heading: {{geolocationGetData.heading}}</text>
        <text class="txt">speed: {{geolocationGetData.speed}}</text>
        <text class="txt">time: {{geolocationGetData.time}}</text>
      </div>
      <input type="button" class="btn" onclick="getGeolocation"
        value="{{$t('message.interface.system.geolocation.getGeolocationBtn')}}" />

      <div class="item-content">
        <text class="txt">{{$t('message.interface.system.geolocation.geolocation')}}</text>
        <text class="txt">latitude: {{geolocationListenData.latitude}}</text>
        <text class="txt">longitude: {{geolocationListenData.longitude}}</text>
        <text class="txt">accuracy: {{geolocationListenData.accuracy}}</text>
        <text class="txt">time: {{geolocationListenData.time}}</text>
      </div>
      <input type="button" class="btn" onclick="listenGeolocation"
        value="{{$t('message.interface.system.geolocation.listenGeolocation')}}" />
      <input type="button" class="btn" onclick="cancelGeolocation"
        value="{{$t('message.interface.system.geolocation.cancelGeolocation')}}" />
      <div class="item-content">
        <text class="txt">{{$t('message.interface.system.geolocation.type')}}{{typeVaule}}</text>
      </div>
      <input type="button" class="btn" onclick="getLocationType"
        value="{{$t('message.interface.system.geolocation.getLocationType')}}" />
      <input type="button" class="btn" onclick="openLocation" value="openLocation" />
      <input type="button" class="btn" onclick="chooseLocation" value="chooseLocation" />
      <input type="button" class="btn" onclick="geocodeQuery" value="geocodeQuery" />
      <input type="button" class="btn" onclick="reverseGeocodeQuery" value="reverseGeocodeQuery" />
    </div>
  </div>
</template>

　　2. 样式如下，大家可以自定义

<style>
  @import '../../../Common/css/common.css';

  .item-container {
    margin-bottom: 50px;
    margin-right: 60px;
    margin-left: 60px;
    flex-direction: column;
  }

  .item-content {
    flex-direction: column;
    background-color: #ffffff;
    padding: 30px;
    margin-bottom: 100px;
    align-items: flex-start;
  }
</style>

　　3. 页面js逻辑

<script>
  import geolocation from '@system.geolocation'
  import device from '@system.device'
  import prompt from '@system.prompt'

    data: {
      componentName: 'geolocation',
