一、手机app定位在我看来有三种方法:
1.通过android自带的api:locationmanager获取到经纬度,再通过geocoder反地理位置查询到所在的地址。
2.外接sdk,如高德sdk,百度sdk直接获得到经纬度和地址
3.通过外部接口获取到外网ip,再通过百度api或者聚合数据的api得出地址
1、android自带api,它有三种定位方式可以通过gps,网络和wifi定位。
1.1步骤:
a.清单文件中配置权限:
b.定位util(从*扒来的~顺带改了下)
package co.chexiao.itwarehouse.util; import android.manifest; import android.content.context; import android.content.pm.packagemanager; import android.location.location; import android.location.locationlistener; import android.location.locationmanager; import android.os.bundle; import android.support.v4.app.activitycompat; import java.util.timer; import java.util.timertask; import co.chexiao.itwarehouse.app.app; /** * author: xx * time:2018/4/23 19:37. * description:*er上的定位 */ public class mylocation { timer timer1; locationmanager lm; locationresult locationresult; boolean gps_enabled = false; boolean network_enabled = false; boolean passive_enabled = false; public boolean getlocation(context context, locationresult result) { // i use locationresult callback class to pass location value from mylocation to user code. locationresult = result; if (lm == null) lm = (locationmanager) context.getsystemservice(context.location_service); //是否可用 try { gps_enabled = lm.isproviderenabled(locationmanager.gps_provider); } catch (exception ex) { } try { network_enabled = lm.isproviderenabled(locationmanager.network_provider); } catch (exception ex) { } try { passive_enabled = lm.isproviderenabled(locationmanager.passive_provider); } catch (exception ex) { } //如果gps和网络还有wifi不行就不开监听 if (!gps_enabled && !network_enabled&& !passive_enabled) return false; //压制警告 if (activitycompat.checkselfpermission(app.getinstance(), manifest.permission.access_fine_location) != packagemanager.permission_granted && activitycompat.checkselfpermission(app.getinstance(), manifest.permission.access_coarse_location) != packagemanager.permission_granted) { return true; } if (gps_enabled) lm.requestlocationupdates(locationmanager.gps_provider, 0, 0, locationlistenergps); if(network_enabled) lm.requestlocationupdates(locationmanager.network_provider, 0, 0, locationlistenernetwork); if(passive_enabled) lm.requestlocationupdates(locationmanager.passive_provider, 0, 0, locationlistenerpassive); timer1=new timer(); timer1.schedule(new getlastlocation(), 20000); return true; } //关闭定位 public void canceltimer() { timer1.cancel(); lm.removeupdates(locationlistenergps); lm.removeupdates(locationlistenernetwork); lm.removeupdates(locationlistenerpassive); } locationlistener locationlistenergps = new locationlistener() { public void onlocationchanged(location location) { timer1.cancel(); locationresult.gotlocation(location); lm.removeupdates(this); lm.removeupdates(locationlistenernetwork); lm.removeupdates(locationlistenerpassive); } public void onproviderdisabled(string provider) {} public void onproviderenabled(string provider) {} public void onstatuschanged(string provider, int status, bundle extras) {} }; locationlistener locationlistenernetwork = new locationlistener() { public void onlocationchanged(location location) { timer1.cancel(); locationresult.gotlocation(location); lm.removeupdates(this); lm.removeupdates(locationlistenergps); lm.removeupdates(locationlistenerpassive); } public void onproviderdisabled(string provider) {} public void onproviderenabled(string provider) {} public void onstatuschanged(string provider, int status, bundle extras) {} }; locationlistener locationlistenerpassive = new locationlistener() { public void onlocationchanged(location location) { timer1.cancel(); locationresult.gotlocation(location); lm.removeupdates(this); lm.removeupdates(locationlistenergps); lm.removeupdates(locationlistenernetwork); } public void onproviderdisabled(string provider) {} public void onproviderenabled(string provider) {} public void onstatuschanged(string provider, int status, bundle extras) {} }; class getlastlocation extends timertask { @override public void run() { lm.removeupdates(locationlistenergps); lm.removeupdates(locationlistenernetwork); lm.removeupdates(locationlistenerpassive); location net_loc=null, gps_loc=null,passive_loc=null; //压制警告 if (activitycompat.checkselfpermission(app.getinstance(), manifest.permission.access_fine_location) != packagemanager.permission_granted && activitycompat.checkselfpermission(app.getinstance(), manifest.permission.access_coarse_location) != packagemanager.permission_granted) { return; } if(gps_enabled) gps_loc=lm.getlastknownlocation(locationmanager.gps_provider); if(network_enabled) net_loc=lm.getlastknownlocation(locationmanager.network_provider); if(passive_enabled) passive_loc=lm.getlastknownlocation(locationmanager.passive_provider); //使用最近的一条 if(gps_loc!=null && net_loc!=null&&passive_loc!=null){ if(gps_loc.gettime()>net_loc.gettime()&&gps_loc.gettime()>passive_loc.gettime()){ locationresult.gotlocation(gps_loc); } else if (net_loc.gettime()>gps_loc.gettime()&&net_loc.gettime()>passive_loc.gettime()){ locationresult.gotlocation(net_loc); }else { locationresult.gotlocation(passive_loc); } return; } if(gps_loc!=null){ locationresult.gotlocation(gps_loc); return; } if(net_loc!=null){ locationresult.gotlocation(net_loc); return; } if(passive_loc!=null){ locationresult.gotlocation(passive_loc); return; } locationresult.gotlocation(null); } } public static abstract class locationresult{ public abstract void gotlocation(location location); } }
c.申请权限获取到经纬度
private void requirepermission() { if (build.version.sdk_int >= build.version_codes.lollipop) { if (contextcompat.checkselfpermission(this, manifest.permission.access_fine_location) != packagemanager.permission_granted && activitycompat.checkselfpermission(myapplication.getinstance(), manifest.permission.access_coarse_location) != packagemanager.permission_granted) { activitycompat.requestpermissions(this, new string[]{manifest.permission.access_coarse_location,manifest.permission.access_fine_location}, my_permissions_request_call_phone); }else{ mylocation.locationresult locationresult = new mylocation.locationresult(){ @override public void gotlocation(location location){ setlocation(location); } }; mylocation mylocation = new mylocation(); mylocation.getlocation(mainactivity.this, locationresult); } } } @override public void onrequestpermissionsresult(int requestcode, @nonnull string[] permissions, @nonnull int[] grantresults) { if (requestcode == my_permissions_request_call_phone){ for (int i = 0; i < grantresults.length; i++) { if (grantresults[i] != packagemanager.permission_granted) { //判断是否勾选禁止后不再询问 boolean showrequestpermission = activitycompat.shouldshowrequestpermissionrationale(mainactivity.this, permissions[i]); if (showrequestpermission) { mytoast.showtoast("权限未申请"); } }else { mylocation.locationresult locationresult = new mylocation.locationresult(){ @override public void gotlocation(location location){ setlocation(location); } }; mylocation mylocation = new mylocation(); mylocation.getlocation(mainactivity.this, locationresult); } } } super.onrequestpermissionsresult(requestcode, permissions, grantresults); }d.将经纬度查询到地址
private void setlocation(location location) { if (location!=null) { string mfeaturename = null; geocoder geocoder = new geocoder(mainactivity.this); list addlist = null;// 解析经纬度 try { addlist = geocoder.getfromlocation(location.getlatitude(), location.getlongitude(), 1); } catch (ioexception e) { e.printstacktrace(); } if (addlist != null && addlist.size() > 0) { for (int i = 0; i < addlist.size(); i++) { address add = addlist.get(i); mfeaturename = add.getfeaturename(); tvlocaiton.settext(mfeaturename); } } } }e.关闭定时器
mylocation.canceltimer();
1.2评价:精确度较强,稳定性一般,300行代码搞定,对app体积影响较小,基本满足普通用户的需求。
2、外接sdk2.1步骤:自己去高德sdk,百度sdk官网接入吧,文档都写的很好。
2.2评价:精确度强,稳定性强,因为需要导入第三方sdk,只用定位这个功能app会增加3、400k的大小,如果需要精准快速定位可以外接sdk
3.通过外部接口获取到外网ip,通过百度api或者聚合数据api将ip解析地址
3.1步骤:
a.请求下面的两个接口,将返回结果通过匹配正则表达式获取到外网ip
cmyiptaobaoip
public static string getouternetformcmyip(string response) { ????pattern pattern = pattern .compile("((?:(?:25[0-5]|2[0-4]\\d|((1\\d{2})|([1-9]?\\d)))\\.){3}(?:25[0-5]|2[0-4]\\d|((1\\d{2})|([1-9]?\\d))))"); ????matcher matcher = pattern.matcher(response.tostring()); ????if (matcher.find()) { ????????string group = matcher.group(); return group; ????} ????return null; }或者直接请求这个接口获取到ip
chanaz
b.获取到ip后,再通过百度api或者聚合数据api将ip解析为地址
聚合数据api
百度api3.2 评价:精确度差,稳定性差,代码量少,对app体积影响较小,不建议使用。
