To store DateTime value into php and mysql

I am working on how to put Date value into my PHP/MySQL using android's date picker.
I want to make a Sharing Parking lot application that owner can register one's parking place with its information like operating time. Then user can use it with choosing the beginning and ending points.
I searched a lot but need more specific information.
How can I save operating time slot into PHP/MySQL?
The following is my android java code.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.avtivity_date_time);
mText1 = (TextView) findViewById(R.id.text1);
mPickDate1 = (Button) findViewById(R.id.pickDate1);
mPickTime1 = (Button) findViewById(R.id.pickTime1);
mText2 = (TextView) findViewById(R.id.text2);
mPickDate2 = (Button) findViewById(R.id.pickDate2);
mPickTime2 = (Button) findViewById(R.id.pickTime2);
mPickDate1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
showDialog(DATE_DIALOG_ID_1);
}
});
mPickDate2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
showDialog(DATE_DIALOG_ID_2);
}
});
mPickTime1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
showDialog(TIME_DIALOG_ID_1);
}
});
mPickTime2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
showDialog(TIME_DIALOG_ID_2);
}
});

How to calculate age based on picked date in DatePickerDialog android?

How could i do this?
This is my code:
private void setDateTimeField () {
Calendar newCalendar = Calendar.getInstance();
mDatePickerDialog = new DatePickerDialog(AddBirthday.this, new OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
addBirthdayDate.setText(dateFormatter.format(newDate.getTime()));
dateSelected = String.valueOf(dayOfMonth) + " /" + String.valueOf(monthOfYear + 1)
+ " /" + String.valueOf(year);
}
}, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
}
I would like now to calculate when is birthday of user when he chose the date in DatePickerDialog and storing it in integer type.

You could try with an easier code like this for example:
private int mDay;
private int mMonth;
private int mYear;
private EditText date;
private Calendar c = new Calendar();
...
//and in your onCreate method:
date = (EditText)findViewById(R.id.date_of_birth_as_text);
date.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
showDialog(DATE_DIALOG_ID); //DATE_DIALOG_ID is the id of your DatePickerDialog - declared in your layout file
}
});
//default values of the year, month and date - will be changed after click on the EditText view
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
updateDisplay();
protected Dialog onCreateDialog(int id) {
switch(id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
}
return null;
}
private DatePickerDialog.OnDateSetListener mDateSetListener= new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, monthOfYear);
c.set(Calendar.DAY_OF_MONTH, dayOfMonth);
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
updateDisplay();
}
};
private void updateDisplay() {
Date currentDate = new Date();
int age = currentDate.getYear() - mYear;
date.setText( new StringBuilder().append("The user is ")
.append(age).append(" years old"));
}

int age = getCurrentYear() -datePicker.getYear() ;

datepicker in android need to check weekend

I am doing datepicker. I am facing some challenges. I am checking wheather selected date is weekend or not. If it is weekend then it should give current date only. Now I don't know where should I put condition in this program and how to get the day of the week and against which thing I should check.
Please, help me.

Limit Time Range in Time Picker

How to control TimePicker, I just want to show time range in time picker from 08:00 am to 02:00 pm (except from 08:00 am to 02:00 pm hide all)
I have written complete code to show TimePicker, and customized time as well.
Here is my code:
case DIALOG_TIME:
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(this, lisTime, hour, minute,
DateFormat.is24HourFormat(MainActivity.this));
TimePickerDialog.OnTimeSetListener lisTime = new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
String meridiem = "";
nim = minute;
Calendar datetime = Calendar.getInstance();
datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
datetime.set(Calendar.MINUTE, minute);
if (datetime.get(Calendar.AM_PM) == Calendar.AM)
meridiem = "AM";
else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
meridiem = "PM";
hour = (datetime.get(Calendar.HOUR) == 0) ?"12":String.valueOf(datetime.get(Calendar.HOUR));
String time = pad(Integer.parseInt(hour)) + ":" + pad(minute) + " " + meridiem;
editTime.setText(time);
}
};
private String pad(int value){
if(value<10){
return "0"+value;
}
return ""+value;
}

As in this answer: https://stackoverflow.com/a/20396673/4130107
You can create your custom TimePickerDialog and overwrite the onAttachedToWindow(); but instead limit the hour range:
private final boolean mIs24HourView;
public CustomTimePickerDialog(Context context, OnTimeSetListener callBack,
int hourOfDay, int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
mIs24HourView = is24HourView;
}
#Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
try {
Class<?> classForid = Class.forName("com.android.internal.R$id");
Field timePickerField = classForid.getField("timePicker");
this.timePicker = (TimePicker) findViewById(timePickerField
.getInt(null));
Field field = classForid.getField("hour");
final NumberPicker mHourSpinner = (NumberPicker) timePicker
.findViewById(field.getInt(null));
if (mIs24HourView) {
mHourSpinner.setMinValue(2);
mHourSpinner.setMaxValue(20);
}else {
Field amPm = classForid.getField("amPm");
mHourSpinner.setMinValue(2);
final NumberPicker amPm = (NumberPicker) timePicker
.findViewById(amPm.getInt(null));
amPm.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
#Override
public void onValueChange(NumberPicker np1, int oldVal, int newVal) {
if (newVal == 0) { // case AM
mHourSpinner.setMinValue(2);
mHourSpinner.setMaxValue(12);
} else { // case PM
mHourSpinner.setMinValue(1);
mHourSpinner.setMaxValue(8);
}
}
});
}
} catch (Exception e) {
e.printStackTrace();
}
}
EDIT: now working for AM/PM too

Dates in all activity

Hi am using Date picker in more than three class with same validation. Instead I must write in one class and call that function in other classes when I required, is it possible Below code for Date picker.
public class MainActivity extends Activity {
private TextView tvDisplayDate;
private Button btnChangeDate;
private int myear;
private int mmonth;
private int mday;
static final int DATE_DIALOG_ID = 999;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setCurrentDateOnView();
addListenerOnButton();
}
// display current date
public void setCurrentDateOnView() {
tvDisplayDate = (TextView) findViewById(R.id.tvDate);
final Calendar c = Calendar.getInstance();
myear = c.get(Calendar.YEAR);
mmonth = c.get(Calendar.MONTH);
mday = c.get(Calendar.DAY_OF_MONTH);
// set current date into textview
tvDisplayDate.setText(new StringBuilder()
// Month is 0 based, just add 1
.append(mmonth + 1).append("-").append(mday).append("-")
.append(myear).append(" "));
}
public void addListenerOnButton() {
btnChangeDate = (Button) findViewById(R.id.btnChangeDate);
btnChangeDate.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
DatePickerDialog _date = new DatePickerDialog(this, datePickerListener, myear,mmonth,
mday)
{
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
if (year < myear)
view.updateDate(myear, mmonth, mday);
if (monthOfYear < mmonth && year == myear)
view.updateDate(myear, mmonth, mday);
if (dayOfMonth < mday && year == myear && monthOfYear == mmonth)
view.updateDate(myear, mmonth, mday);
}
};
return _date;
}
return null;
}
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
myear = selectedYear;
mmonth = selectedMonth;
mday = selectedDay;
// set selected date into textview
tvDisplayDate.setText(new StringBuilder().append(mmonth + 1)
.append("-").append(mday).append("-").append(myear)
.append(" "));
Date dateObject1 = new Date(myear - 1900, mmonth, mday);
Date dateObj2 = new Date(System.currentTimeMillis());
if(dateObject1.before(dateObj2) || dateObject1.equals(dateObj2)){
//the program runs normally
}
else{
new AlertDialog.Builder(MainActivity.this)
.setTitle("Wrong Data Input!")
.setMessage("The end Date must be Before the start Date, please insert new Date values")
.setNeutralButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
}
}).show();
}
}
};
}

You could have a DateUtils class with a static method, which takes in the dates, along with the context. This method can do the date validations and build the AlertDialog accordingly. You can call this static method this way.
DateUtils.dateValidator(Date, Context);
This can be called in the onDateSet() of your OnDateSetListener for each DatePicker.
