Android：发送数据存储在MySQL中

Solved:缺少 postData() 的视图参数，已更改以反映这一点。

我需要一些帮助，将 GPS 数据发送到服务器，该数据将使用 PHP 存储在 MySQL 数据库中。

这是在我的 Java 文件中：

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

public void postData(View v)
{
    nameValuePairs.add(new BasicNameValuePair("Lat","19.80"));
    nameValuePairs.add(new BasicNameValuePair("Lon","13.22"));

    //http post
    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new      
        HttpPost("http://www.xxxxxxxx.com/test.php");
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        InputStream is = entity.getContent();
        Log.i("postData", response.getStatusLine().toString());
    }

    catch(Exception e)
    {
        Log.e("log_tag", "Error in http connection "+e.toString());
    }           
}

还有我的 PHP：

<?php
include 'connect.php'; //Connect

//retrieve the data
$lat = $_POST['lat'];
$lon = $_POST['lon'];

$sql = "INSERT INTO Coords (Lat, Lon) VALUES('$lat', '$lon')";

if (!mysql_query($sql, $sqlCon))
{
    die('Error: ' . mysql_error());
}
else
{
    //echo "1 record added";
}

include 'closeConnection.php';
?>

堆栈跟踪： 项目 - Heat [Android 应用程序]

 onClick handler on view class android.widget.Button with id 'dropLocBtn'

堆栈跟踪的第一行准确地告诉您做错了什么：

02-06 00:37:14.265: ERROR/AndroidRuntime(1607): FATAL EXCEPTION: main
02-06 00:37:14.265: ERROR/AndroidRuntime(1607): java.lang.IllegalStateException: Could not find a method postData(View) in the activity class com.nathanhunston.heat.Main for onClick handler on view class android.widget.Button with id 'dropLocBtn'

那是因为你没有View你的参数postData()方法声明。
