获取位置（经度和纬度）

分类: 技术问答 • 2022-05-09 16:37:45
问题描述：

我是android新手。我写了一个代码。而我的目的是当我得到一个短信发送我的位置传入短信号码。获取位置（经度和纬度）

我可以得到和发送短信，但我不能发送我的位置（作为经度和纬度）。我怎样才能做到这一点。相信我，我不知道我该怎么做。我在onlocationChange（）方法中编写了一些代码。但它不给我位置。

请给我一个建议。

感谢您的帮助。

这里我的代码：

package com.example.smsmessaging; 

import android.annotation.SuppressLint; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent;

import com.google.android.maps.OverlayItem; 

@SuppressLint("UnlocalizedSms") 
public class SmsReceiver extends BroadcastReceiver implements LocationListener 
{ 
    @SuppressLint({ "NewApi", "NewApi", "NewApi" }) 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     Bundle bundle = intent.getExtras(); 
     SmsMessage[] mesaj = null; 
     String str = ""; 
     String sender = ""; 
     if (bundle != null) 
     {   

      Object[] obj = (Object[]) bundle.get("pdus"); 
      mesaj = new SmsMessage[obj.length]; 

      for (int i=0; i<mesaj.length; i++){ 
       mesaj[i] = SmsMessage.createFromPdu((byte[])obj[i]);     
       sender = mesaj[i].getOriginatingAddress();      
       str += mesaj[i].getMessageBody().toString(); 
      } 

      Toast.makeText(context,"SMS," + sender + " tarafından gönderildi\n\nSMS in içeriği : " + 
      str, Toast.LENGTH_LONG).show(); 

      TelephonyManager tMgr =(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
      String mPhoneNumber = tMgr.getLine1Number(); 
      String mIMEINumber = tMgr.getDeviceId(); 
      Toast.makeText(context,"My Phone no : " + mPhoneNumber, Toast.LENGTH_LONG).show(); 
      Toast.makeText(context,"My IMEI no : " + mIMEINumber, Toast.LENGTH_LONG).show(); 

      SmsManager sms = SmsManager.getDefault(); 
      sms.sendTextMessage(sender.toString(), null, str, null, null); 

      Toast.makeText(context,"SMS sent ...", Toast.LENGTH_LONG).show(); 

     }       
    } 

    public void onLocationChanged(Location location) { 
     int lat = Integer.parseInt(location.getLatitude()+" "); 
     int lon = Integer.parseInt(location.getLongitude()+" "); 

     String efe = "Location " + " Longitude : " + lon + "\n Latitude : " + lat; 
     Context context = null; 

     try { 
       SmsManager sms = SmsManager.getDefault(); 
       sms.sendTextMessage("1555215554", null, efe, null, null); 

       Toast.makeText(context,"location sent. Details : " + efe, Toast.LENGTH_LONG).show();      
     } catch (Exception e) { 
        e.printStackTrace(); 
     } 

    } 

    public void onProviderDisabled(String provider) { 
     // TODO Auto-generated method stub 

    } 

    public void onProviderEnabled(String provider) { 
     // TODO Auto-generated method stub 

    } 

    public void onStatusChanged(String provider, int status, Bundle extras) { 
     // TODO Auto-generated method stub 

    }

是你在locationchanged上经纬度？ – Sharmilee

是的，我可以，但我想当我收到短信时，然后发送我的当前位置。 –

我编辑了链接到http://sdrv.ms/WCBFRj，因为它似乎无法访问。如果您有更新的链接，请考虑对此答案进行编辑。 –

答 

String myLocation = "My current location is: " + "Latitude = " 
       + loc.getLatitude() + "Longitude = " + loc.getLongitude();

此代码已经为我工作。
