已解决:缺少postData()的 View 参数,已更改以反射(reflect)这一点。

我想要将GPS数据发送到服务器的帮助,该服务器将使用PHP存储在MySQL数据库中。

这在我的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());
    }
}

而我的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:

 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'

最佳答案

堆栈跟踪的第一行确切地告诉您您在做什么错:

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'

这是因为在View方法声明中没有postData()参数。
