Come ottenere dati da MySQL con due date diverse in Android e visualizzare in Multi Column ListView

Question

Sto passando tre (nome del cliente, data di inizio e data di fine) valori in file PHP ma il problema dietro, non riesco a passare Tre i valori al momento un solo valore (nome del cliente) si è trasferito a PHP file.and come visualizzare la data in MULTI LISTVIEW COLONNA

di file java:

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.customer_repo); 

    // Permission StrictMode 
    if (android.os.Build.VERSION.SDK_INT > 9) { 
     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
     StrictMode.setThreadPolicy(policy); 
    } 

    setCurrentDateOnView(); 
    addListenerOnButton(); 

    cus_name = (Spinner) findViewById(R.id.spinner1);//customer spinner 
    created_date1 = (TextView) findViewById(R.id.tvDate); 
    created_date2 = (TextView) findViewById(R.id.tvDate2); 

    //spinner for customer name 
    cus_name = (Spinner) findViewById(R.id.spinner1); 
    adapter = new ArrayAdapter<String>(this, R.layout.spinner_custo_report, R.id.txt, listItems); 
    cus_name.setAdapter(adapter); 
    cus_name.setAdapter(new NothingSelectedSpinnerAdapter(adapter, R.layout.custo_rep_nothingselect, this)); 


    Button submit = (Button) findViewById(R.id.loadbtn);

        String Stock3 = jsonChildNode.optString("product").toString(); 
        OutputData += Stock1 + Stock2 + Stock3; 


       } 
       /****************** End Parse Response JSON Data *************/ 

       //Show Parsed Output on screen (activity) 
       pro_stock1.setText(OutputData); 

      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 

} 

Ecco l'inizio problema, Come passare quello che devo fare. se ci sono delle opzioni

cus_name +="&" + URLEncoder.encode("cus_name", "UTF-8") + "="+customerName.getSelectedItem(); 
//created_date1 +="&" + URLEncoder.encode("created_date1", "UTF-8") + "="+createddate1.getText(); 
//created_date2 +="&" + URLEncoder.encode("created_date2", "UTF-8") + "="+createddate2.getText(); 

e questo è il modo giusto

wr.write(cus_name); 
    //wr.write(created_date1); 
    //wr.write(created_date2);

Answer 1

Utilizzare una classe del modello di dati, invece di Hashamap per Dataset.

public class CustomerData { 
    String createdAt; 
    String orderNo; 

    public CustomerData(String createdAt, String orderNo) { 
     this.createdAt = createdAt; 
     this.orderNo = orderNo; 
    } 

    public String getCreatedAt() { 
     return createdAt; 
    } 

    public String getOrderNo() { 
     return orderNo; 
    } 
} 

quindi modificare il codice come questo

public void ShowData() { 
// listView1 
    final ListView lisView1 = (ListView) findViewById(R.id.listview_customername); 

    Spinner cus_name = (Spinner) findViewById(R.id.spinner1); 
    TextView created_date1 = (TextView) findViewById(R.id.tvDate); 
    TextView created_date2 = (TextView) findViewById(R.id.tvDate2); 


    String url = "http://192.168.1.13:8090/Vaari_services/getCustomerReportData.php"; 

    // Paste Parameters 
    //List<NameValuePair> params = new ArrayList<NameValuePair>(); 

    new GetCustomerDataTask().execute(url); 

} 
private class GetCustomerDataTask extends AsyncTask<String, Void, String> { 
    @Override 
    protected String doInBackground(String... urls) { 
     // params comes from the execute() call: params[0] is the url. 
     try { 
      return downloadUrl(urls[0]); 
     } catch (IOException e) { 
      return "Unable to retrieve web page. URL may be invalid."; 
     } 
    } 
    // onPostExecute displays the results of the AsyncTask. 
    @Override 
    protected void onPostExecute(String result) { 
     parseData(result); 
    } 
} 


    // Given a URL, establishes an HttpUrlConnection and retrieves 
// the web page content as a InputStream, which it returns as 
// a string. 
private String downloadUrl(String myurl) throws IOException { 
    InputStream is = null; 
    // Only display the first 500 characters of the retrieved 
    // web page content. 
    int len = 500; 

    List<NameValuePair> params = new ArrayList<>(); 

    params.add(new BasicNameValuePair("cus_name", cus_names); 
    params.add(new BasicNameValuePair("created_date1", createddate); 
    params.add(new BasicNameValuePair("created_date2", created_date); 



    try { 
     URL url = new URL(myurl); 
     HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
     conn.setReadTimeout(10000 /* milliseconds */); 
     conn.setConnectTimeout(15000 /* milliseconds */); 
     conn.setRequestMethod("POST"); 
     conn.setDoInput(true); 
     // Starts the query 
     conn.connect(); 
     int response = conn.getResponseCode(); 
     Log.d(DEBUG_TAG, "The response is: " + response); 
     is = conn.getInputStream(); 

     // Convert the InputStream into a string 
     String contentAsString = readIt(is, len); 
     return contentAsString; 

     // Makes sure that the InputStream is closed after the app is 
     // finished using it. 
    } finally { 
     if (is != null) { 
      is.close(); 
     } 
    } 
} 


public void parseData(String response){ 
    try { 
     JSONObject parentObject = new JSONObject(response); 
     JSONArray data = parentObject.getJSONArray("customer_repo"); 

     //JSONArray data = new JSONArray(getJSONUrl(url,params)); 
     ArrayList<CustomerData> customerArrayList = new ArrayList<CustomerData>(); 
     for (int i = 0; i < data.length(); i++) { 
      JSONObject c = data.getJSONObject(i); 
      String createdDate = c.getString("created_date"); 
      String orderNo = c.getString("created_date"); 
      customerArrayList.add(new CustomerData(createdDate, orderNo)); 
     } 

     imageAdapter = new ImageAdapter(this, customerArrayList); 
     lisView1.setAdapter(imageAdapter);
