我正在将三个(客户名称、开始日期和结束日期)值传递给 PHP 文件，但背后的问题是，我当时没有传递三个值，只有一个值(客户名称)移动到 PHP 文件。并且如何在多列列表中显示日期

java文件:

                //Show Parsed Output on screen (activity)

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

}

这是问题的开始，如何传递我必须做的事情。如果有任何选择

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();

这是正确的方法

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

最佳答案

对数据集使用数据模型类而不是 HashMap 。

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;
    }
}

然后像这样修改你的代码

 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);
        imageAdapter.notifyDataSetChanged();
        registerForContextMenu(lisView1);


    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

   public class ImageAdapter extends BaseAdapter {
    private Context context;
    ArrayList<CustomerData> customerDataArrayList;

    public ImageAdapter(Context c,ArrayList<CustomerData>   customerDataArrayList) {
        // TODO Auto-generated method stub
        context = c;
        this.customerDataArrayList= customerDataArrayList;
    }

    public int getCount() {
        // TODO Auto-generated method stub
        return customerDataArrayList.size();
    }

    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return customerDataArrayList.get(position);
    }

    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if (convertView == null) {
            convertView = inflater.inflate(R.layout.activity_cus_report, null);
        }

        // created date
        TextView txtOrdDate = (TextView) convertView.findViewById(R.id.ColOrDate);
        txtOrdDate.setPadding(10, 0, 0, 0);
        txtOrdDate.setText(customerDataArrayList.get(position).getCreatedAt() + ".");
        txtOrdDate.setTextSize(18);
        txtOrdDate.setTextColor(Color.parseColor("#FFFFFF"));

        // Oredr No
        TextView txtOrdNo = (TextView) convertView.findViewById(R.id.ColOrNo);
        txtOrdNo.setPadding(5, 0, 0, 0);
        txtOrdNo.setText(customerDataArrayList.get(position).getOrderNo());
        txtOrdNo.setTextSize(18);
        txtOrdNo.setTextColor(Color.parseColor("#FFFFFF"));

        return convertView;

    }

}

同时发布你的getJSONUrl方法
