1.MapView ,MapActivity 这种的局限在于,必须要继承MapActivity,否则无法使用MapView。纠结就在于此。但是,***官网上已经弃用了这糟粕的MapActivity。
Version 1 of the Google Maps Android API as been officially deprecated as of December 3rd, 2012. This means that from March 3rd, 2013 you will no longer be able to request an API key for this version. No new features will be added to Google Maps Android API v1. However, apps using v1 will continue to work on devices. Existing and new developers are encouraged to use Google Maps Android API v2.
MapFragment是刚出的google官方包,要集成进来还是挺麻烦的。官网链接
- 首先要到google conlose 添 加api access权限,拿到apikey,创建一个project ,然后到services里把Google Maps Android API v2打开,再到api access里把你的project的keystore的SHA1和包名填进去,拿到唯一的api key
- 打开sdk manager--在Extras里把Android Support Libaray 和 Google Play Services都安装,lib和samples都在sdk_path/extra/google/google_play_services下。导 入../lib_project作为自己项目的libaray
- 这一步完了之后在manifest.xml文件里添加权限和api key。代码如下:
- <permission
- android:name="com.example.permission.MAPS_RECEIVE"
- android:protectionLevel="signature"/>
- com.example替换成自己project的package
- <uses-permission android:name="com.example.permission.MAPS_RECEIVE"/>
- <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
- <uses-permission android:name="android.permission.INTERNET"/>
- <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
- <!--My Location-->
- <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
- <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
- <!--Maps API needs OpenGL ES2.0.-->
- <uses-feature
- android:glEsVersion="0x00020000"
- android:required="true"/>
- 放在application声明里
- <meta-data
- android:name="com.google.android.maps.v2.API_KEY"
- android:value="appkey"/>
在layout xml里加入MapFragment声明:
- <fragment xmlns:android="http://schemas.android.com/apk/res/android"
- android:id="@+id/map"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- class="com.google.android.gms.maps.MapFragment"/>
activity不变,extends Activity就可以了。 不需要继承MapActivity了。
注意,debug状态下是不可以显示地图的,一定要在正式签名下map才会显示出来。
install下应该就能看到map了。
还有不懂的就多看看官方文档把,介绍的很清楚。
