How to create datePicker and timePicker dialogs in fragment class?
You will most likely need to use a DialogFragment. I found some information here:
Show dialog from fragment?
and also a big help here:
https://github.com/commonsguy/cw-advandroid/blob/master/Honeycomb/FeedFragments/src/com/commonsware/android/feedfrags/AddFeedDialogFragment.java
This should help you get on your way, I am doing this very thing now. Though inside the example code I don't use a builder and instead just return:
return new DatePickerDialog(getActivity(), mDateSetListener, mYear, mMonth, mDay);
This seems to work... though I cannot figure out yet how to update the text on the fragment that calls this DialogFragment. I thought this would work and it doesn't:
public void updateDisplay()
{
//update our button text from the calling fragment, this isn't quite working
//doesn't crash just doesn't update...must be missing something.
View v=getActivity()
.getLayoutInflater()
.inflate(R.layout.session_edits, null);
Button sessionDate = (Button)v.findViewById(R.id.sessionPickDate);
sessionDate.setText(new StringBuilder()
.append(mMonth+1).append("-").append(mDay).append("-").append(mYear).append(" "));
}
Create a DatePicker and TimePicker in the Tab Fragment error
At first rectify your onCreateView method .
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
contentView=inflater.inflate(R.layout.daily_weight_fragement, container, false);
btnTime = (EditText) contentView.findViewById(R.id.time_field);
btnTime.setOnClickListener(this);
btnDate = (EditText) contentView.findViewById(R.id.date_field);
btnDate.setOnClickListener(this);
return contentView;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
Logcat Returns
Error:(79, 35) error: no suitable constructor found for
DatePickerDialog(KeyInWeightF,,int,int,int) constructor
DatePickerDialog.DatePickerDialog(Context,int,OnDateSetListener,int,int,int)
is not applicable (actual and formal argument lists differ in length)
constructor
DatePickerDialog.DatePickerDialog(Context,OnDateSetListener,int,int,int)
is not applicable (actual argument KeyInWeightF cannot be converted to
Context by method invocation conversion)
Solutions
You should use getActivity() instead of KeyInWeightF.this
getActivity() in a Fragment returns the Activity the Fragment is currently associated with.
timePickerDialog = new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {
As same as
String timestring = DateUtils.formatDateTime(getActivity(),timeCalendar.getTimeInMillis(),DateUtils.FORMAT_SHOW_TIME);
Get date and time picker value from a single dialog fragment and set it in EditText
Date Picker and Time Picker both in single dialog. check this code.

How do I create a date/time picker in a separate class and use it in various classes?
If you are using Fragments use this class:
public class DatePickerDialogFragment extends DialogFragment {
private Context context;
private Calendar MinDate, MaxDate;
private OnDateSetListener mDateSetListener;
public DatePickerDialogFragment() {
}
public DatePickerDialogFragment(OnDateSetListener callback, Calendar MinDate, Calendar MaxDate, Context context) {
mDateSetListener = callback;
this.MinDate = MinDate;
this.MaxDate = MaxDate;
this.context = context;
}
public DatePickerDialogFragment(OnDateSetListener callback, Context context) {
mDateSetListener = callback;
this.context = context;
}
DatePickerDialog dd;
DatePicker dp;
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar cal = Calendar.getInstance();
dd = new DatePickerDialog(getActivity(), this.mDateSetListener, cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH));
dd.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
try {
if (MinDate!=null&&MaxDate!=null) {
((DatePickerDialog) dialog).getDatePicker().setMaxDate(MaxDate.getTimeInMillis());
((DatePickerDialog) dialog).getDatePicker().setMinDate(MinDate.getTimeInMillis());
}
} catch (NullPointerException e) {
dialog.dismiss();
e.printStackTrace();
}
}
});
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
return dd;
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
}
And use it like:
dialogFragment = new DatePickerDialogFragment(new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar cal = GregorianCalendar.getInstance();
cal.set( year, monthOfYear, dayOfMonth);
String currentDateandTime = sdf.format( cal.getTime());
et_date.setText(currentDateandTime);
}
}, context);
And Show it like
dialogFragment.show(getFragmentManager(), "Date");

}
showing a DatePickerDialog inside a Dialogfragment
The solution isn't about the datepickerdialog at all. I had a switch-case in my fragment that manages the events of clicks. I accidentally forgot to put a break; after the case which caused a flow to the other events (one of them was dismiss();), and that's why the datepickerdialog also dismissed my fragment.
