Hi group,
I trying to use Datepicker widget to select the date and pass to
google gdata api to fetch calender events
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth)
{
mYear = year;
mMonth = monthOfYear+1; // why is that step up is
needed
mDay = dayOfMonth;
updateDisplay();
}
};
private void updateDisplay() {
StringBuilder status= new StringBuilder(50);
String y1=String.valueOf(mYear);
String m1=String.valueOf(mMonth);
if(m1.length()==1)
{
m1="0"+m1;
}
String d1=String.valueOf(mDay);
if(d1.length()==1)
{
d1="0"+d1;
}
String startdate=y1+"-"+m1+"-"+d1+"T"+"00:00:00";
//example out put for startdate:2009-02-12T00:00:00
String enddate=y1+"-"+m1+"-"+d1+"T"+"23:59:59";
try{
myQuery.setMinimumStartTime(DateTime.parseDateTime(startdate));
myQuery.setMaximumStartTime(DateTime.parseDateTime(enddate));;
Feed resultFeed = myService.query(myQuery, Feed.class);
for (int i = 0; i < resultFeed.getEntries().size(); i++) {
Entry entry = resultFeed.getEntries().get(i);
status.append("\t" + entry.getTitle().getPlainText());
}
}catch(Exception e){System.out.println(e);}
mDateDisplay.setText(status);
}
I will be glad if someone clarifies few points
1. Why is that this step up is needed - > mMonth = monthOfYear+1;
2. DateTime.parseDateTime(String args) takes date format as
2009-02-12T00:00:00 and is there any other simple approach to convert
int values from Datepicker to required format,the one shown above
doesn't work .At present i hard-code values to make it work ,like
myQuery.setMinimumStartTime(DateTime.parseDateTime("2010-02-12T00:00:00"));
myQuery.setMaximumStartTime(DateTime.parseDateTime("2010-03-12T23:59:59"));
3. The code works fine(when i hard code the as shown above) for the
very time of execution .when i clicked back button and again tried to
run the app ,resultFeed throws Null pointer exception.
I could appreciate your valuable suggestion to correct my mistakes.
Thanks
ganesh
