LocationService
使用高德地图android定位sdk进行封装，以remote service方式提供定位功能
##配置工程
-
高德lbs官网申请key 申请地址
-
在mainfest进行一下配置
1：配置定位所需权限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" /> 2：配置所需key
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="您申请的key" />3：配置定位service
<service
android:process=":remote"
android:name="com.amap.apis.locationservice.LocationBackGroundService">完成以上操作后可以进行定位的开发
##定位功能
- 实例化定位Client
mLocationClient = new LocationClient(getApplicationContext());- 设置定位参数
LocationClientOption locationOption = new LocationClientOption();
//设置定位间隔
locationOption.setScanSpan(2000);
//设置定位模式，其他模式见LocationMode
locationOption.setLocationMode(LocationMode.Battery_Saving);
mLocationClient.setLocOption(locationOption);- 设置定位监听
GDLocationListener gdLocationListener = new GDLocationListener() {
@Override
public void onReceiveLocation(GDLocation location) {
Log.i("location",
location.getAddrStr() + " " + location.getCity()
+ " " + location.getCityCode() + " "
+ location.getDistrict() + " "
+ location.getLatitude() + " "
+ location.getLongitude()+" "
+location.getStreet()+" "
+location.getRadius()+" "
+location.getProvince()+" "
+location.getSpeed()
);
}
};
mLocationClient.registerLocationListener(gdLocationListener);- 开始定位
//开启定位
mLocationClient.start(); - 停止定位
mLocationClient.stop(); ##地理围栏功能
- 实例化地理围栏Client
mGeofenceClient=new GeofenceClient(getApplicationContext());- 设置地理围栏监听
//设置地理围栏的监听
mGeofenceClient.registerGeofenceTriggerListener(new OnGeofenceTriggerListener() {
@Override
public void onGeofenceTrigger(String geofenceID) {
Log.i("location", "in the geofence"+geofenceID);
}
@Override
public void onGeofenceExit(String geofenceID) {
Log.i("location", "out of the geofence"+geofenceID);
}
});- 添加地理围栏
//创建地理围栏，设置地理围栏id,范围和有效时间
GDGeofence gdGeofence=new GDGeofence.Builder().
setGeofenceId("testGeofence")
.setCircularRegion(116.480829, 39.989614, 1000).setExpirationDruation(1000*60)
.build();
//添加地理围栏，注意同一个地理围栏id只能添加一次
mGeofenceClient.addGDGeofence(gdGeofence, new OnAddGDGeofencesResultListener() {- 开启地理围栏扫描
mGeofenceClient.start();- 停止地理围栏扫描
mGeofenceClient.stop();##注意事项
-
LocationClient与GeofenceClient的start()方法会启动remote service，因此注意在合适的业务场景和生命周期中调用相对的stop()方法停止后台的定位进程
-
设置LocationClient的LocationClientOption时，最终定位会以第一个最先设置的参数生效
-
目前地理围栏支持单个listener的回调，即已设置的最后一个listener进行回调，如果有类似定位LocationClient多个listener回调需求，后续会增加此功能的支持
