Question

I have 2 datepickers and 2 timepickers on a screen and also a submit button. The user selects the start date, start time, end date, and end time. The program then takes these values and stores them into variables, however the variables only return the default values for these controls. Is there anyway to get the updated value from each of these controls?

My code looks like this for the edit screen:

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

    timepickerStart = (TimePicker)findViewById(R.id.timePicker1);
    timepickerEnd = (TimePicker)findViewById(R.id.timePicker2);
    datepickerStart = (DatePicker)findViewById(R.id.datePicker1);
    datepickerEnd = (DatePicker)findViewById(R.id.datePicker2);

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

    locationText = (EditText)findViewById(R.id.locationText);
    eventText = (EditText)findViewById(R.id.eventText);

}

public void DateStart(View v)
{
    GlobalVariables.datepickerYearStart = datepickerStart.getYear();
    GlobalVariables.datepickerMonthStart = datepickerStart.getMonth();
    GlobalVariables.datepickerDayStart = datepickerStart.getDayOfMonth();
}

public void DateEnd(View v)
{
    GlobalVariables.datepickerYearEnd = datepickerEnd.getYear();
    GlobalVariables.datepickerMonthEnd = datepickerEnd.getMonth();
    GlobalVariables.datepickerDayEnd = datepickerEnd.getDayOfMonth();
}

public void TimeStart(View v)
{
    GlobalVariables.timepickerHourStart = timepickerStart.getCurrentHour();
    GlobalVariables.timepickerMinuteStart = timepickerStart.getCurrentMinute();
}

public void TimeEnd(View v)
{
    GlobalVariables.timepickerHourEnd = timepickerEnd.getCurrentHour();
    GlobalVariables.timepickerMinuteEnd = timepickerEnd.getCurrentMinute();
}

public void submitClicked(View v)
{

    startActivity(new Intent(this, AddToCalendar.class));
}

Rewrite

Looking at your current code, let’s stick with the various get methods from DatePicker and TimePicker. However you never call DateStart() or any of the others, they look like you have them set up for an OnClickListener… Regardless, try this:

public void submitClick(View v) {
    DateStart(null);
    TimeStart(null);
    DateEnd(null);
    TimeEnd(null);

    // Do what you please your GlobalVariables
}

Though I might leave out the multiple GlobalVariables and store one long value for each date/time:

public void submitClick(View v) {
    Calendar calendar = Calendar.getInstance();
    calendar.set(datepickerStart.getYear(), datepickerStart.getMonth(),
                 datepickerStart.getDayOfMonth(), timepickerStart.getCurrentHour(), 
                 timepickerStart.getCurrentMinute(), 0);
    long startTime = calendar.getTimeInMillis();

    // And similar approach for the end time, then use them however you please
}
