推荐答案

在@DarkXphenomenon答案大厦，请确保您有正确的权限。

Building upon @DarkXphenomenon answer, make sure you have the right permissions.

// to retrieve location
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
// to retrieve location
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
// to send data
<uses-permission android:name="android.permission.INTERNET"/>

然后在你的java类，你可以使用这个code将数据发送到PHP文件。确保捕获任何异常。

Then in your java class you can use this code to send the data to the php file. Make sure to catch any exceptions.

String and = "&";

                    HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://my site.com/gpsdata.php?imei="+imei+and+"lat="+lat+and+"lng="+lng+and+"alt="+alt+and+"spd="+speed);

        try {

             httpclient.execute(httppost);
            Log.d(TAG, "Data sent!");
        } catch (ClientProtocolException e) {
            Toast.makeText(this,
                    "Client protokol exception ", Toast.LENGTH_LONG).show();
        } catch (IOException e) {
            Toast.makeText(this,
                    "IO exception " + e.getMessage(), Toast.LENGTH_LONG)
                    .show();
        }

您还需要确保你的位置的变量，如经纬度是字符串，否则你会得到一些意外的错误。通常情况下，位置变量将是一个双重或浮动。一个双转换为字符串，excecute

You also need to make sure that your location variables such as latitude or longitude are strings otherwise you will get some unexpected errors. Normally the location variables would be a double or a float. To convert a double to a string, excecute

String Longitude = Double.toString(doubleToConvertToString);

和同样一个浮点数到字符串

And likewise a Float to a String

String Longitude = Float.toString(doubleToConvertToString);
