难以将用户1的位置发送给用户2，将用户2的位置发送给用户1？

我有一个代码将用户1的位置发送给用户2，用户2的位置发送给用户1。 用户1的位置完美地发送给用户2，用户2甚至向用户1发送消息，但是它发送的位置是用户1的位置而不是他（用户2）的位置。

这是我的代码：

package com.example.gui; import android.app.Activity; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.ContentResolver; import android.content.ContentValues; import android.content.Context; import android.content.Intent; import android.database.Cursor; import android.location.Geocoder; import android.location.Location; import android.location.LocationManager; import android.net.Uri; import android.os.Bundle; import android.telephony.SmsManager; import android.telephony.SmsMessage; import android.util.Log; import android.view.View; import android.widget.Toast; public class ReceivelocationActivity extends BroadcastReceiver { private static final String TAG = "LocationActivity"; public static final String SMS_URI = "content://sms"; public static final String ADDRESS = "address"; public static final String PERSON = "person"; public static final String DATE = "date"; public static final String READ = "read"; public static final String STATUS = "status"; public static final String TYPE = "type"; public static final String BODY = "body"; public static final String SEEN = "seen"; public static final int MESSAGE_TYPE_INBOX = 1; public static final int MESSAGE_TYPE_SENT = 2; public static final int MESSAGE_IS_NOT_READ = 0; public static final int MESSAGE_IS_READ = 1; public static final int MESSAGE_IS_NOT_SEEN = 0; public static final int MESSAGE_IS_SEEN = 1; private static final String LOCATION_SERVICE = null; LocationManager locationManager; Geocoder geocoder; double longitude,latitude; @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Intent m=new Intent(context, ReceivelocationActivity.class); PendingIntent pi=PendingIntent.getBroadcast(context, 0, m, 0); Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str = ""; String str2=""; String str3=""; String autoReplyToken = "Request_Accepted"; if (bundle != null) { //---retrieve the SMS message received--- Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for (int i=0; i<msgs.length; i++){ msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]); str += "SMS from " + msgs[i].getOriginatingAddress(); str2=msgs[i].getOriginatingAddress(); str += " :"; str += msgs[i].getMessageBody().toString(); str3=msgs[i].getMessageBody().toString(); str += "\n"; } //---display the new SMS message--- Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); // int number=Integer.parseInt(str2); SmsManager sms = SmsManager.getDefault(); boolean isAutoReply = str3.startsWith(autoReplyToken); locationManager = (LocationManager)this.getSystemService(LOCATION_SERVICE); geocoder = new Geocoder(this); Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); if (location != null) { Log.d(TAG, location.toString()); this.onLocationChanged(location); } String msg = Double.toString(latitude) + " " +Double.toString(longitude) ; if (!isAutoReply) { String autoReplyText = autoReplyToken + msg; sms.sendTextMessage(str2, null, autoReplyText, pi, null); } // sms.sendTextMessage(str2, null, "Whats up", pi, null); } } public void onLocationChanged(Location location) { // TODO Auto-generated method stub latitude=location.getLatitude(); longitude=location.getLongitude(); } private void putSmsToDatabase( ContentResolver contentResolver, SmsMessage sms ) { // Create SMS row ContentValues values = new ContentValues(); values.put( ADDRESS, sms.getOriginatingAddress() ); values.put( DATE, sms.getTimestampMillis() ); values.put( READ, MESSAGE_IS_NOT_READ ); values.put( STATUS, sms.getStatus() ); values.put( TYPE, MESSAGE_TYPE_INBOX ); values.put( SEEN, MESSAGE_IS_NOT_SEEN ); // Push row into the SMS table contentResolver.insert( Uri.parse( SMS_URI ), values ); } } 

谁能告诉我我哪里做错了？

pastebin.com/53ZJH3iN这是回复用户1收到的短信的文件。 它不是发送用户2的位置，而是将从用户1获得的相同位置发送回给他。（这里的位置指的是经度和纬度）。 请帮帮我。我突然想到这个

你遇到的一个问题是第102行：

 String msg = Double.toString(latitude) + " " +Double.toString(longitude) ; 

您尚未更新纬度和经度以反映您当前的位置。 在该行之前添加此代码：

 latitude = location.getLatitude(); longitude = location.getLongitude(); 

看看修复后会发生什么。
