很难将用户 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,它将用户 1 的位置发送给用户 2,将用户 2 的位置发送给用户 1.用户 1 的位置完美地发送给了用户 2,用户 2 甚至向用户 1 发送了一条消息,但它发送的位置是用户 1 的位置,而不是他(用户 2)的位置.
I have a code which sends location of user 1 to user 2 and user 2's location to user 1 . The location of user 1 is send perfectly to user 2 and user 2 is even sending a message back to user 1 but the location which it is sending is the location of user 1 not his (user 2) location.
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 += "
";
}
//---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 );
}
}
谁能告诉我哪里做错了?
Can anyone tell me where am I doing wrong?
pastebin.com/53ZJH3iN 这是回复从用户 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.(这里的位置是指经度和纬度).请帮帮我.我对此感到头疼
pastebin.com/53ZJH3iN this is the file which reply back to a sms received from user 1 . Instead of sending user 2's location it is sending same location obtained from user 1 back to him.(Here location refers to longitude and latitude). Please help me.I'm breaking my head on this
推荐答案
你遇到的一个问题是在第 102 行:
Well one problem you have is at line 102:
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:
You haven't updated latitude and longitude to reflect your current position. Add this code right before that line:
latitude = location.getLatitude();
longitude = location.getLongitude();
看看修复后会发生什么.
See what happens once that is fixed.
