我正在编写一个应用程序，我需要在其中使用PHP MySQL更新数据，并且每次我收到消息“成功更新数据”。但是每当我查看我的数据库时，我都没有得到任何值的变化。

我不确定，但我认为您应该需要在SaveData()中使用以下行：

    final TextView tUserID = (TextView)findViewById(R.id.txtUserID);
    final TextView tAppointmentID = (TextView)findViewById(R.id.txtAppointmentID);

所以你的SavaData()应该是这样的：

public boolean SaveData()
        {
        final TextView txtUserID = (TextView)findViewById(R.id.txtUserID);
        final TextView txtAppointmentID = (TextView)findViewById(R.id.txtAppointmentID);
        final EditText txtType = (EditText)findViewById(R.id.txtType);
        final EditText txtDate = (EditText)findViewById(R.id.txtDate);
        final EditText txtTime = (EditText)findViewById(R.id.txtTime);

        //Dialog
        final AlertDialog.Builder ad = new AlertDialog.Builder(this);

        ad.setTitle("Error! ");
        ad.setIcon(android.R.drawable.btn_star_big_on);
        ad.setPositiveButton("Close", null);

        String url = "http://10.0.2.2/appointments/updateData.php";

        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("sUserID", txtUserID.getText().toString()));
        params.add(new BasicNameValuePair("sAppointmentID", txtAppointmentID.getText().toString()));
        params.add(new BasicNameValuePair("sType", txtType.getText().toString()));
        params.add(new BasicNameValuePair("sDate", txtDate.getText().toString()));
        params.add(new BasicNameValuePair("sTime", txtTime.getText().toString()));

        String resultServer  = getHttpPost(url,params);
        Log.d(tag, "resultServer - updateData:: " + resultServer);

        /*** Default Value ***/
        String strStatusID = "0";
        String strMessage = "Unknow Status!";

        JSONObject c;
        try {
        c = new JSONObject(resultServer);
        strStatusID = c.getString("StatusID");
        strMessage = c.getString("Message");
        } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }

        // Prepare Save Data
        if(strStatusID.equals("0"))
        {
        ad.setMessage(strMessage);
        ad.show();
        return false;
        }
        else
        {
        Toast.makeText(UpdateActivity.this, "Update Data Successfully", Toast.LENGTH_SHORT).show();
        }        

        return true;
        }

我们知道您正在使用 UserID 和 AppointmentID 来获取所有约会，所以每当您进行更改时，它需要特定的 UserID 和 AppointmentID 指向您单击的那一行...可能是原因

请告诉我这个:)

你错过$了WHERE声明。也不要使用已弃用mysql_*的函数并验证您从用户那里收到的数据！

发生的事情是你的 PHP 中没有“错误”，它的“消息”。所以它会在 try catch 模块中出现异常。

更改strMessage = c.getString("Error");为strMessage = c.getString("Message");

就是这样..然后它会工作..

对于 PHP

$strUserID = $_POST["sUserID"];
$strAppointmentID = $_POST["sAppointmentID"];

$strType = $_GET["sType"];
$strDate = $_GET["sDate"];
$strTime = $_GET["sTime"];

$strSQL = 'UPDATE book_appointment 
           SET 
              Type = "'.$strType.'",
              Date = "'.$strDate.'",
              Time = "'.$strTime.'" 
           WHERE AppointmentID = "'.$strAppointmentID.'"';
