推荐答案

1）只有您自己的应用程序可以使用



2）您的应用需要将其位置发送到全局服务器。



3）您在全局服务器中查询用户位置。



4）你在地图上显示位置列表。



到目前为止你做了什么？

1) It is only possible for your own applications

2) Your app needs to send it's "location" to a global server.

3) You query the global server for users locations.

4) You show the list of locations on a map.

Step 2 A from Solution 1

GPSTracker gpsTracker = new GPSTracker(this);
        if (gpsTracker.canGetLocation()) {
            String stringLatitude = String.valueOf(gpsTracker.latitude);
            textview = (TextView) findViewById(R.id.fieldLatitude);
            textview.setText("Latitude: " + stringLatitude);

            String stringLongitude = String.valueOf(gpsTracker.longitude);
            textview = (TextView) findViewById(R.id.fieldLongitude);
            textview.setText("Longitude: " + stringLongitude);

            String country = gpsTracker.getCountryName(this);
            textview = (TextView) findViewById(R.id.fieldCountry);
            textview.setText("Country: " + country);

            String city = gpsTracker.getLocality(this);
            textview = (TextView) findViewById(R.id.fieldCity);
            textview.setText("City: " + city);

            String postalCode = gpsTracker.getPostalCode(this);
            textview = (TextView) findViewById(R.id.fieldPostalCode);
            textview.setText("PostalCode: " + postalCode);

            String addressLine = gpsTracker.getAddressLine(this);
            textview = (TextView) findViewById(R.id.fieldAddressLine);
            textview.setText("AddressLine: " + addressLine);
        } else {
            // can't get location
            // GPS or Network is not enabled
            // Ask user to enable GPS/network in settings
            gpsTracker.showSettingsAlert();
        }
