使用百度地图进行定位,我选择的插件是:react-native-baidu-map
github地址:https://github.com/lovebing/react-native-baidu-map
样例:
此处我只写了配置Android的教程,需要ios配置的可以移步至:http://www.jianshu.com/p/eceb7e66fa5e ,作者写的很详细。
配置步骤:
1、导入
npm install react-native-baidu-map --save
2、link
react-native link react-native-baidu-map
3、配置
有时候link可能没起作用,或者link只自动配置了一半而没有配全,所以我们需要手动去检查一些是否都配置全了,去过没有配置全,还需手动去配置。
setting.gradle
include ':react-native-baidu-map' project(':react-native-baidu-map').projectDir = new File(settingsDir, '../node_modules/react-native-baidu-map/android’)
App/build.gradle
compile project(':react-native-baidu-map')
MainApplication
new BaiduMapPackage(getApplicationContext())
除此之外,别忘了将包导进来:不过一般都会自动导进来。
MainApplication
import org.lovebing.reactnative.baidumap.BaiduMapPackage;
AndroidMainifest.xml
开启权限:
<!-- 访问GPS定位 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- 网络定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- 用于访问wifi网络信息,wifi信息会用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE” />
配置百度地图AK:
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value=“你所申请的百度地图AK”/>
申请百度地图AK可参考:http://www.jianshu.com/p/2e2c562a2275
现在所有的配置都已经完成了,我们就可以进行百度地图定位了。
