如何在我的Android应用中集成Google地图

问题描述 投票：0回答：2

我正在开发Android应用程序，其中需要显示地图。我工作了3天，但没有得到任何积极的结果。

我按照本教程Google Maps Android API v2。但是，当我运行我的应用程序。它只是给予例外

IOException processing: 26
java.io.IOException: Server returned: 3
at android_maps_conflict_avoidance.com.google.googlenav.map.BaseTileRequest.readResponseData(BaseTileRequest.java:115)
at android_maps_conflict_avoidance.com.google.googlenav.map.MapService$MapTileRequest.readResponseData(MapService.java:1473)

at android_maps_conflict_avoidance.com.google.googlenav.datarequest.DataRequestDispatcher$DispatcherServer.run(DataRequestDispatcher.java:1702)

这是我的代码：

活动：

public class DisplayMap extends  MapActivity{

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

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}

XML：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent">

    <com.google.android.maps.MapView 
        android:id="@+id/mapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="AIzaSyA1MXQ1Hc4-VhOOfItFHA1WCsGFUGcJ-BQ"
        />

</RelativeLayout>

表现：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.rakhi577.maptest"
    android:versionCode="1"

    <uses-feature

        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps" />
        <activity

            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyA1MXQ1Hc4-VhOOfItFHA1WCsGFUGcJ-BQ"/>


</manifest>

我使用debug.keystore创建了地图。任何人都可以帮助我...

使用Google地图v2

      <fragment  
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
       android:layout_below="@id/rg_views"
      android:name="com.google.android.gms.maps.SupportMapFragment"
      />

和A.java

Googlemap gm;

gm =（（SupportMapFragment）（getSupportFragmentManager（）。findFragmentById（R.id.map）））。getMap（）;

在这里可以看到完整的教程。 http://www.vogella.com/articles/AndroidGoogleMaps/article.html

并且在清单文件中，要给出的权限集

<uses-permission android:name=".LocationGoogleMapV2Demo.permission.MAPS_RECEIVE"/>

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>

将此代码用于谷歌地图我从androidhive.com这样做

import com.google.api.client.googleapis.GoogleHeaders;
import com.google.api.client.http.GenericUrl;

    public PlacesList search(double latitude, double longitude, double radius, String types)

        try {

            HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
            HttpRequest request = httpRequestFactory
                    .buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
            request.getUrl().put("key", API_KEY);
            request.getUrl().put("location", _latitude + "," + _longitude);

            return list;

        } catch (HttpResponseException e) {
            Log.e("Error:", e.getMessage());
            return null;
        }

    }

    /**

     * @param refrence - reference id of place
     *                 - which you will get in search api request

    public PlaceDetails getPlaceDetails(String reference) throws Exception {
        try {

            request.getUrl().put("key", API_KEY);
            request.getUrl().put("reference", reference);
            request.getUrl().put("sensor", "false");

            PlaceDetails place = request.execute().parseAs(PlaceDetails.class);

            return place;

        } catch (HttpResponseException e) {
            Log.e("Error in Perform Details", e.getMessage());
            throw e;
        }
    }

    /**
     * Creating http request Factory
     * */
    public static HttpRequestFactory createRequestFactory(
            final HttpTransport transport) {
        return transport.createRequestFactory(new HttpRequestInitializer() {
            public void initialize(HttpRequest request) {
                GoogleHeaders headers = new GoogleHeaders();
                headers.setApplicationName("AndroidHive-Places-Test");
                request.setHeaders(headers);
                JsonHttpParser parser = new JsonHttpParser(new JacksonFactory());
                request.addParser(parser);
            }
        });
    }

}

对于api密钥你可以打开androidhive.com并注册到这个..我可以得到关于谷歌地图的教程
