Question

您好我在点击显示日期选择器对话框和时间选择器对话框中使用了两个按钮。我有一个旋转器。

我想将用户输入值发送到php服务器。我该怎么做客户端代码？

这是我的代码：

public class DineOutActivity extends Activity {

    private TextView mDateDisplay;
    private Button mPickDate;
    private int mYear;
    private int mMonth;
    private int mDay;
   /******************time picker**************/
        private TextView mTimeDisplay;
           private Button mPickTime;
           private int mHour;
           private int mMinute;
           private int mAmPm;

           static final int TIME_DIALOG_ID=1;

        static final int DATE_DIALOG_ID = 0;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        /********************spinner***********/

        Spinner food = (Spinner) findViewById(R.id.spinner1);
        ArrayAdapter<CharSequence> foodadapter = ArrayAdapter.createFromResource(
                    this, R.array.item_array, android.R.layout.simple_spinner_item);
        foodadapter.setDropDownViewResource(R.layout.spinner_layout);
        food.setAdapter(foodadapter);
        /**pick date*/

        mDateDisplay = (TextView) findViewById(R.id.textView2);
        mTimeDisplay = (TextView) findViewById(R.id.textView4);
        mPickDate = (Button) findViewById(R.id.button2);
       /**pick time**/

        mPickTime=(Button)findViewById(R.id.button3);

        // add a click listener to the button
        mPickTime.setOnClickListener(new View.OnClickListener() {

                     public void onClick(View v) {

                           showDialog(TIME_DIALOG_ID);
                     }
              });

        // get the current time
        final Calendar c=Calendar.getInstance();
        mHour=c.get(Calendar.HOUR_OF_DAY);
        mMinute=c.get(Calendar.MINUTE);
        mAmPm = c.get(Calendar.AM_PM);

        // display the current date
       upTimeDisplay();


/*****************************pick date***********************************/
        // add a click listener to the button
        mPickDate.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v1) {
                showDialog(DATE_DIALOG_ID);
            }
        });

        // get the current date
        final Calendar date = Calendar.getInstance();
        mYear = date.get(Calendar.YEAR);
        mMonth = date.get(Calendar.MONTH);
        mDay = date.get(Calendar.DAY_OF_MONTH);
        int mDst = date.get(Calendar.AM_PM);
        int mAmPm = date.get(Calendar.DST_OFFSET);

        // display the current date (this method is below)
        updateDisplay();
    }

    // updates the date in the TextView




   private void upTimeDisplay()
   {
     //  mTimeDisplay.setText(new  
           //    StringBuilder().append(pad(mHour)).append(":").append(pad(mMinute)).append(pad(mAmPm)));
       mTimeDisplay.setText(new  
                  StringBuilder().append(mHour).append(":").append(mMinute));
       mTimeDisplay.setTextColor(R.color.green);
   }
  /** private Object pad(int mMinute2) {

       if(mMinute2>=10)
              return String.valueOf(mMinute2);
       else
              return "0"+String.valueOf(mMinute2);
}**/

   private TimePickerDialog.OnTimeSetListener mtimeSetListener=new  
           TimePickerDialog.OnTimeSetListener() {

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

mHour=hourOfDay;
mMinute=minute;
int ampm;

upTimeDisplay();
}
};


    private void updateDisplay() {
        mDateDisplay.setText(new StringBuilder()
                    // Month is 0 based so add 1
                    .append(mMonth + 1).append("-")
                    .append(mDay).append("-")
                    .append(mYear).append(" "));
        mDateDisplay.setTextColor(R.color.green);
                 //   .append(mHour).append("_")
                  //  .append(mMinute).append("_")));
    }

    // the callback received when the user "sets" the date in the dialog
    private DatePickerDialog.OnDateSetListener mDateSetListener =
            new DatePickerDialog.OnDateSetListener() {

                public void onDateSet(DatePicker view, int year, 
                                      int monthOfYear, int dayOfMonth) {
                    mYear = year;
                    mMonth = monthOfYear;
                    mDay = dayOfMonth;
                    updateDisplay();
                }
            };

    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DATE_DIALOG_ID:
            return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
                    mDay);

        case TIME_DIALOG_ID:
            return new TimePickerDialog(this,mtimeSetListener,mHour,mMinute,false);
        }
        return null;
    }

我使用mPickDate作为打开DatePickerDialog的按钮 mPickTime作为单击打开TimePicker对话框的按钮一个Spinner（spinner1）获取项目列表。 mDateDisplay显示用户在单击DatePickerDialog后编辑的日期。 mTimeDisplay显示用户在单击TimePickerDialog后编辑的时间。

我希望DatePickerDialog，TimePickerDialog和spinner的用户输入的字符串值作为HTTP post发送到服务器。请告诉我怎么做？我想要详细的代码。

Answer 1

public void postData() {

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("text", "blablabla"));
        nameValuePairs.add(new BasicNameValuePair("date", "yourdate"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}

Answer 2

    // Create a new HttpClient and Post Header
    String downloadedString= null;

    HttpClient httpclient = new DefaultHttpClient();


    //for registerhttps://te
    HttpPost httppost = new HttpPost("url here");
    //add data
    try{
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(7);
        nameValuePairs.add(new BasicNameValuePair("firstname", "harsh"));
        nameValuePairs.add(new BasicNameValuePair("lastname", "chandel"));
        nameValuePairs.add(new BasicNameValuePair("email", "mike.bulurt66@gmail.com"));
        nameValuePairs.add(new BasicNameValuePair("phone", "944566778"));
        nameValuePairs.add(new BasicNameValuePair("username", "mikebulurt"));
        nameValuePairs.add(new BasicNameValuePair("password", "qwert"));
        nameValuePairs.add(new BasicNameValuePair("device_duid", "986409987"));

        //add data
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

        InputStream in = response.getEntity().getContent();
        StringBuilder stringbuilder = new StringBuilder();
        BufferedReader bfrd = new BufferedReader(new InputStreamReader(in),1024);
        String line;
        while((line = bfrd.readLine()) != null)
            stringbuilder.append(line);

        downloadedString = stringbuilder.toString();

    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    System.out.println("downloadedString:in login:::"+downloadedString);


    return downloadedString;
