Question

我想显示一个MapView，可用于选择StreetView在单独区域中显示的点。我知道API在一个进程中不允许多个MapView。

如何让StreetView显示在与显示MapView不同的区域？

我能够毫无问题地抓住静态街景，但我希望拥有动态街景和MapView。

您可以在WebView中加载360度全景Google street-view。

尝试以下活动，其中google-street-view和google-map可以在单个活动中同时导航：

public class StreetViewActivity extends Activity {

    private WebView webView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mappingWidgets();
    }

    private void mappingWidgets() {

        webView = (WebView) findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);

        webView.getSettings().setLoadWithOverviewMode(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.getSettings().setSupportZoom(false);  


        // If you want to load it from assets (you can customize it if you want)
        //Uri uri = Uri.parse("file:///android_asset/streetviewscript.html");

        // If you want to load it directly
        Uri uri = Uri.parse("https://google-developers.appspot.com/maps/documentation/javascript/examples/full/streetview-simple");
        webView.loadUrl(uri.toString());
    }
}

您可以将其作为静态HTML页面放在应用程序的assets文件夹中，然后使用Google street-view API根据需要修改它的java脚本。

我在这里发布您可以放在应用程序的assets文件夹中的示例streetviewscript.html，并根据您的需要对其进行自定义：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Google Maps JavaScript API v3 Example: Street View Layer</title>
    <link href="/maps/documentation/javascript/examples/default.css" rel="stylesheet">
    <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=true"></script>
    <script>

      function initialize() {
        var fenway = new google.maps.LatLng(42.345573,-71.098326);
        var mapOptions = {
          center: fenway,
          zoom: 14,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(
            document.getElementById('map_canvas'), mapOptions);
        var panoramaOptions = {
          position: fenway,
          pov: {
            heading: 34,
            pitch: 10,
            zoom: 1
          }
        };
        var panorama = new  google.maps.StreetViewPanorama(document.getElementById('pano'),panoramaOptions);
        map.setStreetView(panorama);
      }
    </script>
  </head>
  <body onload="initialize()">
    <div id="map_canvas" style="width: 800px; height: 800px"></div>
    <div id="pano" style="position:absolute; left:810px; top: 8px; width: 800px; height: 800px;"></div>
  </body>
</html>

修改：要同时导航两个街道视图，请从资源加载以下HTML：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Google Maps JavaScript API v3 Example: Street View Events</title>

    <STYLE type="text/css"> 
        body, html { height:100%; padding:0; margin:0;} 
        #pano { float:left }
        #pano1 { float:right }
    </STYLE>
    <link href="/maps/documentation/javascript/examples/default.css" rel="stylesheet">
    <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
    <script>

      var cafe = new google.maps.LatLng(37.869085,-122.254775);

      var heading_value = 270;
      var pitch_value = 0;
      var zoom_value = 1;

      function initialize() {

        var panoramaOptions = {
          position: cafe,
          pov: {
            heading: heading_value,
            pitch: pitch_value,
            zoom: zoom_value
          },
          visible: true
        };

        var panorama = new google.maps.StreetViewPanorama(document.getElementById('pano'), panoramaOptions);
        var panorama2 = new google.maps.StreetViewPanorama(document.getElementById('pano1'), panoramaOptions);  

        google.maps.event.addListener(panorama, 'pano_changed', function() {
            var panoCell = document.getElementById('pano_cell');
            panoCell.innerHTML = panorama.getPano();
            panorama2.setPano(panorama.getPano());
        });

        google.maps.event.addListener(panorama, 'links_changed', function() {
            var linksTable = document.getElementById('links_table');
            while(linksTable.hasChildNodes()) {
              linksTable.removeChild(linksTable.lastChild);
            };
            var links =  panorama.getLinks();
            panorama2.setLinks(panorama.getLinks());
            for (var i in links) {
              var row = document.createElement('tr');
              linksTable.appendChild(row);
              var labelCell = document.createElement('td');
              labelCell.innerHTML = '<b>Link: ' + i + '</b>';
              var valueCell = document.createElement('td');
              valueCell.innerHTML = links[i].description;
              linksTable.appendChild(labelCell);
              linksTable.appendChild(valueCell);
            }
        });

        google.maps.event.addListener(panorama, 'position_changed', function() {
            var positionCell = document.getElementById('position_cell');
            positionCell.firstChild.nodeValue = panorama.getPosition();
            panorama2.setPosition(panorama.getPosition());
        });

        google.maps.event.addListener(panorama, 'pov_changed', function() {
            var headingCell = document.getElementById('heading_cell');
            var pitchCell = document.getElementById('pitch_cell');
            headingCell.firstChild.nodeValue = panorama.getPov().heading;
            panorama2.setPov(panorama.getPov());
            pitchCell.firstChild.nodeValue = panorama.getPov().pitch;
        });
    }
    </script>

Answer 2

如何让StreetView显示在与显示MapView不同的区域？

街景视图仅作为自己的活动（来自其自己的应用程序）在设备上提供，因此无法与您自己的任何小部件一起显示。

Answer 3

在Android上查看https://developers.google.com/maps/documentation/android/code-samples处提供的街景全景和地图示例。但我不确定它是否也适用于自定义街景。
