Php 如何为我的应用程序用户添加点数并将其连接到android？

我已经开始了一个项目的工作，但是我在这里遇到了麻烦，我需要为我已经存储在数据库中的每个用户添加点。我已经创建了一个数据库，我在其中存储用户的用户名和密码，并将其连接到android。一切都正常，但现在在我的例子中，我想在用户解决问题时为他们存储点，例如在我的应用程序中，但我不知道如何为此编写方法，需要php的一些帮助

这些是我的php文件：Register.php

还有一个：FetchUserData.php

那么，我现在如何在这里为每个用户包括点呢

这是我用于将android连接到php和mysql的java文件：

    public class ServerRequests {

    ProgressDialog progressDialog;
    public static final int CONNECTION_TIMEOUT = 1000 * 15;
    public static final String SERVER_ADRESS = "http://192.168.0.17:8081/project/";

    public ServerRequests(Context context){
        progressDialog = new ProgressDialog(context);
        progressDialog.setCancelable(false);
        progressDialog.setTitle(R.string.progress_dialog);
        progressDialog.setMessage("Please wait...");
    }

    public void storeUserDataInBackground(User user, GetUserCallback userCallback){
        progressDialog.show();
        new StoreUserDataAsyncTask(user, userCallback).execute();
    }

    public void fetchUserDatainBackground(User user, GetUserCallback callBack){
        progressDialog.show();
        new fetchUserDataAsyncTask(user, callBack).execute();
    }

    public class StoreUserDataAsyncTask extends AsyncTask<Void, Void, Void>{
        User user;
        GetUserCallback userCallback;

        public StoreUserDataAsyncTask(User user, GetUserCallback userCallback){
            this.user = user;
            this.userCallback = userCallback;
        }

        @Override

            dataToSend.add(new BasicNameValuePair("username", user.username));
            dataToSend.add(new BasicNameValuePair("password", user.password));

        }
    }

    public class fetchUserDataAsyncTask extends AsyncTask<Void, Void, User> {

            dataToSend.add(new BasicNameValuePair("password", user.password));

            HttpConnectionParams.setConnectionTimeout(httpRequestParams, CONNECTION_TIMEOUT);
            HttpConnectionParams.setSoTimeout(httpRequestParams, CONNECTION_TIMEOUT);

            HttpClient client = new DefaultHttpClient(httpRequestParams);
            HttpPost post = new HttpPost(SERVER_ADRESS + "FetchUserData.php");

            User returnedUser = null;
            try {
                post.setEntity(new UrlEncodedFormEntity(dataToSend));
                HttpResponse httpResponse = client.execute(post);

                HttpEntity entity = httpResponse.getEntity();

这是我第一次将android连接到在线数据库，我仍在学习android开发，因此我希望这里能提供任何帮助。：）

您的问题表明您对基本术语有一些问题。 . 当您创建了一个帐户（顺便说一句，数据库最好不要存储）时，您可能会完全一样地记录：发送用户名和密码。如果它存在于数据库中，请创建

（）

现在，您将能够根据用户的请求（通过会话）确定是否已到达

并将数据添加到表中

id | login | score

这是最简单的解决办法。祝你好运
