共享地图基于位置的 [英] Sharing Map based Location

问题描述

我已经开发了显示在地图上自己的位置的应用程序。我该如何去和别人谁使用我的应用程序分享我当前的位置？是否可以向他们发送通知，让他们知道我现在的位置？

I have developed an application that shows one's location on a map. How do I go about sharing my current location with others who are using my application? Is it possible to send them a notification to let them know my current location?

推荐答案

这是我用来发送的位置是利用 maps.google.com 网​​站的一种格式，这样的：

A format that I use to send a location is to leverage the maps.google.com site, like:

"http://maps.google.com/maps?q=" + loc_x + "," + loc_y + "&iwloc=A"

本字符串可插入一个短信或电子邮件消息。我发现本网站与格式化的URL自动打开集中在给定的坐标映射一些好的信息。一个可能实现的短信可能是：

This String can be inserted into a SMS or Email message. I found this site with some good info for formating a URL to automatically open a map centered on the given coordinates. A possible implementation for SMS could be:

String message = 
             "http://maps.google.com/maps?q=" + loc_x + "," + loc_y + "&iwloc=A";

private void sendSMS(String phoneNumber, String message){

    SmsManager sms = SmsManager.getDefault();
    Log.d(TAG, "Attempting to send an SMS to: " + phoneNumber);
    try {
        sms.sendTextMessage(phoneNumber, null, message, null, null);
    } catch (Exception e) {
        Log.e(TAG, "Error sending an SMS to: " + phoneNumber + " :: " + e);
    }       

}  

其中， loc_x 和 loc_y 重present纬度和经度从 LocationManager 实例。

Where loc_x and loc_y represent lat and lon from a LocationManager instance.
