问题描述

我一直在寻找一种方式将数据发送到远程服务器和无法在一个PHP页面似乎得到它的工作...我修改了code从<一个类似的问题href=\"http://stackoverflow.com/questions/15963039/sending-json-data-from-android-to-php-and-writing-to-text-file\">here
但它不still..do工作,我必须把httppost在AsyncTask的什么?我会怎么做呢? code:

 公共类GAMEOVER延伸活动{
// TextView的hiscores;
保护无效的onCreate(捆绑savedInstanceState){
    super.onCreate(savedInstanceState);
    的setContentView(R.layout.gameover);    最后键b =(按钮)findViewById(R.id.button1);
    b.setOnClickListener(新View.OnClickListener(){
        @覆盖
        公共无效的onClick(视图v){
            //执行上的点击动作            Toast.makeText(gameOver.this按钮是pssed $ P $,
                    Toast.LENGTH_SHORT).show();
            尝试{
                JSONObject的JSON =新的JSONObject();
                json.put(时间戳,1351181576.64078);
                json.put(姓名,engine_speed);
                json.put(价值,714.0);
                POSTDATA(JSON);                JSONObject的json2 =新的JSONObject();
                json2.put(时间戳,1351181576.7207818);
                json2.put(姓名,steering_wheel_angle);
                json2.put(价值,11.1633);
                POSTDATA(json2);
            }赶上(JSONException E){
                e.printStackTrace();
            }        }
    });
}公共无效POSTDATA(JSONObject的JSON)抛出JSONException {
    HttpClient的HttpClient的=新DefaultHttpClient();
字符串的URL =htt​​p://www.mysite.com/s.php;
    尝试{
        HttpPost httppost =新HttpPost(URL);        清单&LT;&的NameValuePair GT; NVP =新的ArrayList&LT;&的NameValuePair GT;(2);
        nvp.add(新BasicNameValuePair(JSON,json.toString()));        httppost.setEntity(新UrlEn codedFormEntity(NVP));
        HTT presponse响应= httpclient.execute(httppost);        如果(响应!= NULL){
            InputStream为= response.getEntity()的getContent()。
            //输入流的反应,可以看出加回Android
            Toast.makeText(gameOver.this,(CharSequence的)是,
                    Toast.LENGTH_SHORT).show();
        }其他{Toast.makeText(gameOver.this,数据未寄出
                Toast.LENGTH_SHORT).show();}
    }赶上(例外五){

解决方案

您应该使用的AsyncTask ,以使发送数据。我不知道你的PHP页面,但是我将试图解释如何将数据从Android的使用JSON发送到服务器(如果您有任何进一步的问题请参考本教程的 http://www.androidhive.info/2012/05/how-to-connect-android-with-php -mysql / )。您发送三个值到服务器作为POST请求。我想你的PHP文件应该得到的三个变量,并将其插入到数据库中,然后相应地发回数据。

您的PHP文件(我假设你希望将这些值插入到一个名为细节有三列的时间戳,名称,值数据库,然后告诉应用程序的用户数据是否被插入或不。)

insert.php

 &LT; PHP    //连接到数据库    //声明数组为en code你的回应
    $ ARR =阵列();    如果((使用isset($ _ POST [时间戳]))及及(使用isset($ _ POST [名称]))及及(使用isset($ _ POST [值)))
     {
       $时间= $ _ POST [时间戳];
       $名称= $ _ POST [名称];
       $值= $ _ POST [值];
       $查询=插入详细信息(时间戳,名称,值)值'$时间,$名称','$价值';
       $结果= mysql_query($结果);
         如果($结果){
      //成功插入到数据库
         $常用3 [成功] = 1;
         $常用3 [消息] =数据插入成功。    //呼应JSON响应
        回声json_en code($ ARR);
        }其他{
        //没有插入一行
         $常用3 [成功] = 0;
         $常用3 [消息] =发生错误。        //呼应JSON响应
        回声json_en code($ ARR);
       }
       }其他{
       //必填字段缺失
       $常用3 [成功] = 0;
       $常用3 [消息] =必填字段(s)是失踪;      //呼应JSON响应
      回声json_en code($ ARR);
      }
?&GT;

您GAMEOVER类必须有一个子类whiich必须扩展的AsyncTask 并做JSON插入。

        //执行上的点击动作        Toast.makeText(gameOver.this按钮是pssed $ P $,

        新插入()执行();    }
});
}类插入扩展的AsyncTask&LT;字符串,字符串,字符串&GT;{@覆盖

    params.add(新BasicNameValuePair(姓名,engine_speed));
    params.add(新BasicNameValuePair(价值,714.0));    //获取JSON对象
    JSONObject的JSON = jsonParser.makeHtt prequest(&lt;您的域,名称&gt; /insert.php,POST,则params);    //Log.d(\"JSON:,json.toString());    尝试
    {
        成功= json.getInt(成功);        如果(成功== 1){
            Log.d(查询,数据插入成功);
        }其他{
            Log.d(查询,不成功的数据submition);

I have been searching for a way to send data to a php page on a remote server and cant seem to get it to work...I modified the code from a similar question on here but it doesnt work still..do I have to put the httppost in an asynctask or something? How would I do that? Code:

public class gameOver extends Activity {
//TextView hiscores;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gameover);

    final Button b = (Button) findViewById(R.id.button1);
    b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Perform action on click

            Toast.makeText(gameOver.this, "button was pressed",
                    Toast.LENGTH_SHORT).show();
            try {
                JSONObject json = new JSONObject(); 
                json.put("timestamp", 1351181576.64078); 
                json.put("name", "engine_speed");
                json.put("value", 714.0);
                postData(json);

                JSONObject json2 = new JSONObject(); 
                json2.put("timestamp", 1351181576.7207818); 
                json2.put("name", "steering_wheel_angle");
                json2.put("value", 11.1633);
                postData(json2);
            } catch (JSONException e) {
                e.printStackTrace();
            }

        }
    });     
}

public void postData(JSONObject json) throws JSONException {
    HttpClient httpclient = new DefaultHttpClient();
String URL = "http://www.mysite.com/s.php";
    try { 
        HttpPost httppost = new HttpPost(URL);

        List<NameValuePair> nvp = new ArrayList<NameValuePair>(2);    
        nvp.add(new BasicNameValuePair("json", json.toString()));

        httppost.setEntity(new UrlEncodedFormEntity(nvp));
        HttpResponse response = httpclient.execute(httppost); 

        if(response != null) {
            InputStream is = response.getEntity().getContent();
            //input stream is response that can be shown back on android
            Toast.makeText(gameOver.this, (CharSequence) is,
                    Toast.LENGTH_SHORT).show();
        }else{       Toast.makeText(gameOver.this, "data Not sent",
                Toast.LENGTH_SHORT).show();}


    }catch (Exception e) {

You should you use AsyncTask to make send the data. I do not know your php page however I will try to explain how to send data to a server from android using JSON (If you have any further problems refer to this tutorial http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/). You are sending three values to the server as a POST request. I think your php file should receive the three variables and insert them into a database and then send back data accordingly.

Your php file (I am assuming you want to insert these values into a database named Details having three columns timestamp,name,value and then tell the app user if the data has been inserted or not.)

insert.php

<?php

    //connect to your database

    //declare an array to encode your response
    $arr = array();

    if((isset($_POST["timestamp"]))&&(isset($_POST["name"]))&&(isset($_POST["value"])))
     {
       $time = $_POST["timestamp"];
       $name = $_POST["name"];
       $value = $_POST["value"];
       $query = "insert into Details(timestamp,name,value) values '$time','$name','$value'";
       $result = mysql_query($result);
         if ($result) {
      // successfully inserted into database
         $arr["success"] = 1;
         $arr["message"] = "Data successfully inserted.";

    // echoing JSON response
        echo json_encode($arr);
        } else {
        // failed to insert row
         $arr["success"] = 0;
         $arr["message"] = "An error occurred.";

        // echoing JSON response
        echo json_encode($arr);
       }
       } else {
       // required field is missing
       $arr["success"] = 0;
       $arr["message"] = "Required field(s) is missing";

      // echoing JSON response
      echo json_encode($arr);
      }
?> 

Your class gameOver must have a subclass whiich must extend AsyncTask and do the JSON insertion.

gameOver Activity

      public class gameOver extends Activity {
    //TextView hiscores;
   JSONParser jsonParser; 
   protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gameover);

final Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
    @Override 
    public void onClick(View v) {
        // Perform action on click 

        Toast.makeText(gameOver.this, "button was pressed",
                Toast.LENGTH_SHORT).show();
        new Insert().execute();

    } 
});      
} 

class Insert extends AsyncTask<String, String, String>

{

@Override
    protected void onPreExecute() {
      super.onPreExecute();
      pDialog = new ProgressDialog(gameOver.this);
      pDialog.setMessage("Inserting Details..");
      pDialog.setIndeterminate(false);
      pDialog.setCancelable(true);
      pDialog.show();
  }

@Override
protected String doInBackground(String... arg0) {

    jsonParser = new JSONParser();

    //Building Parameters
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("timestamp",1351181576.64078));
    params.add(new BasicNameValuePair("name","engine_speed"));
    params.add(new BasicNameValuePair("value", 714.0));

    //getting JSON Object
    JSONObject json = jsonParser.makeHttpRequest("<your-domain-name>/insert.php", "POST", params);

    //Log.d("JSON:",json.toString());

    try
    {
        success = json.getInt("success");

        if(success == 1){
            Log.d("Query","Data Successfully inserted");
        }else{
            Log.d("Query","Unsuccessful in data submition");
        }
    }catch(JSONException e){
        Log.d("JSON:","EXCEPTION");
    }

    return null;
}    

The JSONParser class mentioned above is

        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        json = sb.toString();
    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }

    // try parse the string to a JSON object
    try {

    return jObj;

}
