我试图在android中创建一个应用程序，它可以在点击按钮时将一些数据发布到php服务器上。点击该按钮后，该应用程序没有任何反应。日志没有显示任何连接尝试。

这是我正在使用的php文件：
<?php
include 'database.php';
$vID = $_POST['vehicleId'];
$latitude=$_POST['latitude'];
$longitude=$_POST['longitude'];
$userid = $_POST['uid'];
$sqlline = " INSERT INTO $userid VALUES ('$vID','$latitude','$longitude')";
$result=mysql_query($sqlline);
?>
这个php文件是否正确？
答案 0 :(得分：0)
我使用以下代码解决了问题：
final TextView hello=(TextView)findViewById(R.id.hello);
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://httptestingjawzf.host56.com/androidpost.php");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("vehicleId", "abc"));
nameValuePairs.add(new BasicNameValuePair("latitude", "abc"));
nameValuePairs.add(new BasicNameValuePair("longitude", "abc"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
String responseStr = EntityUtils.toString(resEntity).trim();
Log.v("TAG", "Response: " + responseStr);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
} catch (NullPointerException n) {
}
catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
使用getEntity（）函数!!
