Google Map V2在Android中的应用

1、安装Google Play services SDK

打开Android SDK Manager，安装和更新Extras下的Google Play services即可。

2、安装Google Play Store和Google Play services

见附件中的com.android.vending.apk和com.google.android.gms.apk。

3、获取API Key

请参考：Google Map Android API V2中API Key的生成

4、修改AndroidManifest.xml

1）在<application>元素中加入子标签：

<meta-data            android:name="com.google.android.maps.v2.API_KEY"            android:value="AIzaSyAhyvAAt3rdR8ATIH2VKlLzjhb9ICDy3UM" />

将其中的android:value换成自己申请的API Key。

2）加入许可信息

<permission        android:name="com.example.demo.permission.MAPS_RECEIVE"        android:protectionLevel="signature" />    <uses-permission android:name="com.example.demo.permission.MAPS_RECEIVE" />

将其中的com.example.demo换成自己的包名。

3）加入其它许可设置

<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" />

4）加入OpenGL ES V2特性的支持

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

5、加载Google Play services类库

在Eclipse里选择：File > Import > Android > Existing Android Code Into Workspace，然后点击Next，找到路径下的/Users/jsntghf/Projects/adt-bundle-mac-x86_64-20130219/sdk/extras/google/google_play_services/libproject/google-play-services_lib，最后点击Finish。

6、添加对Google Play services类库的引用

在项目上右键，选择Properties，左边选择Android，然后在下面的Library里添加刚才的google-play-services_lib。

7、显示地图

1）布局文件

<?xml version="1.0" encoding="utf-8"?><fragment xmlns:android="http://schemas.android.com/apk/res/android"  android:id="@+id/mapview"  android:layout_width="match_parent"  android:layout_height="match_parent"  class="com.google.android.gms.maps.SupportMapFragment"/>

2）MainActivity.java

package com.example.demo;import com.google.android.gms.common.ConnectionResult;import com.google.android.gms.common.GooglePlayServicesUtil;import com.google.android.gms.maps.CameraUpdateFactory;import com.google.android.gms.maps.GoogleMap;import com.google.android.gms.maps.SupportMapFragment;import com.google.android.gms.maps.model.BitmapDescriptorFactory;import com.google.android.gms.maps.model.LatLng;import com.google.android.gms.maps.model.MarkerOptions;import android.os.Bundle;import android.app.Activity;import android.app.Dialog;import android.support.v4.app.FragmentActivity;import android.view.Menu;public class MainActivity extends FragmentActivity {private GoogleMap googleMap;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());if (status != ConnectionResult.SUCCESS) {int requestCode = 10;Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this,requestCode);dialog.show();} else {SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapview);googleMap = fm.getMap();LatLng sfLatLng = new LatLng(-43.507227, 172.72233);googleMap.moveCamera(CameraUpdateFactory.newLatLng(sfLatLng));if (googleMap != null) {googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);googleMap.getUiSettings().setCompassEnabled(true);googleMap.getUiSettings().setZoomControlsEnabled(true);googleMap.getUiSettings().setMyLocationButtonEnabled(true);googleMap.addMarker(new MarkerOptions() .position(sfLatLng) .title("New Brighton") .snippet("New Brighton") .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(sfLatLng, 15));googleMap.animateCamera(CameraUpdateFactory.zoomIn());googleMap.animateCamera(CameraUpdateFactory.zoomTo(10), 2, null);}}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}
