Question

我是android新手。我写了一个代码。我的目的是当我收到短信时将我的位置发送到收到的短信号码。

我可以收到并发送短信，但我无法发送我的位置（如纬度和经度）。我怎样才能做到这一点。相信我，我不知道我是怎么做到的。我在onlocationChange（）方法中编写了一些代码。但它并没有给我位置。

请给我一个建议。

感谢您的帮助。

这是我的代码：

package com.example.smsmessaging; 

import android.annotation.SuppressLint;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.location.Address;
import android.location.Criteria;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.telephony.TelephonyManager;
import android.widget.Toast;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.MapView;
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

    }

}

最后我找到了解决方案。我编辑的代码如下：

package com.example.donemprojesi;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_ana);
        finish();
        LocationManager locationManager = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);

            LocationListener locationListener = new LocationListener() {
                public void onLocationChanged(Location location) {
                    updateLocation(location);
                    SmsManager sms = SmsManager.getDefault();

                    if("efe".equals(str) && SmsReceiver.flag == true){
                        try{
                            sms.sendTextMessage(SmsReceiver.sender.toString(), null,"Koordinatlar : Enlem = " +currentLatitude +

                        }
                        finally{
                            SmsReceiver.flag =false;
                            finish();
                        }
                    }
                }
                public void onStatusChanged(

                public void onProviderEnabled(String provider) {/*Toast.makeText(getApplicationContext(), "GPS Enabled", Toast.LENGTH_SHORT).show();*/}
                public void onProviderDisabled(String provider) {/*Toast.makeText(getApplicationContext(), "GPS Disabled", Toast.LENGTH_SHORT).show();*/}
            };

            locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
            bildirim();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_ana, menu);
        return true;
    }

    public void bildirim(){

        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = android.R.drawable.ic_menu_view;
        CharSequence ticketText = "GPSMS Started";

        mNotificationManager.notify(NOTIFICATION_ID, notification);
        mNotificationManager.notify(BIND_AUTO_CREATE, notification);

    public String getAddress(){
        try{
            Geocoder gcd = new Geocoder(this, Locale.getDefault());
            List<Address> addresses = gcd.getFromLocation(currentLatitude, currentLongitude,100);

                    Address address =  (Address) addresses.get(0);

        catch(IOException ex){

    void updateLocation(Location location){
        currentLocation = location;
        currentLatitude = currentLocation.getLatitude();
        currentLongitude = currentLocation.getLongitude();
        currentAddress = getAddress();
    }   
}

Answer 2

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

此代码对我有用。
