    <p>In AddPeriod.java you create a TimePickerDialog.OnTimeSetListener but as far as I can see that listener isn't used.</p> <p>In TimePickerFragment.java you implement the TimePickerDialog.OnTimeSetListener interface and pass the fragment instance itself as a listener to the TimePickerDialog but you do nothing in the implemented onTimeSet() method in TimePickerFragment.java. Are you saying that onTimeSet() in TimePickerFragment.java isn't called? Have you set a breakpoint?</p> <p>If you manage to get the onTimeSet() called in your fragment I assume what you're really asking for is how to pass this time back to the activity. If I'm correct I'd say that this is a perfect place to use an event bus, for instance using <a href="http://square.github.io/otto/" rel="nofollow">Otto</a>.</p> <p>UPDATE: Based on your comments to my questions I assume that what you really want is a way to get the picked time in TimePickerFragment back to AddPeriod. The better approach is in my opinion to use an event bus (as mentioned above). This will decouple your fragment from your activity. BUT to give you an answer that works with minimal changes to your code I suggest that you pass a listener to the fragment and use that listener when you create your dialog:</p> <p>TimePickerFragment.java:</p> <pre><code>public class TimePickerFragment extends DialogFragment { private TimePickerDialog.OnTimeSetListener listener; public TimePickerFragment(TimePickerDialog.OnTimeSetListener listener) { super(); this.listener = listener; } @Override public Dialog onCreateDialog(Bundle savedInstanceState) { // Use the current time as the default values for the picker 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(getActivity(), listener, hour, minute, DateFormat.is24HourFormat(getActivity())); } } </code></pre> <p>As you can see I've added a constructor that takes a TimePickerDialog.OnTimeSetListener argument. This listener is used when the TimePickerDialog is created. Now in our AddPeriod activity we pass the mTimeSetListener to the fragment when it is created:</p> <pre><code>public class AddPeriod extends SherlockFragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.add_period); } public void showTimePickerDialog(View v) { DialogFragment newFragment = new TimePickerFragment(mTimeSetListener); newFragment.show(getSupportFragmentManager(), "timePicker"); } TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(android.widget.TimePicker view, int hourOfDay, int minute) { Log.i("",""+hourOfDay+":"+minute); } }; } </code></pre>

    1. COI don´t know how to make the call. Sorry for my expression. I don´t know hot to implement what I want. I have seen other examples but it was not whith fragments.

    2. COCOuld you please confirm if you get a call to onTimeSet() in your fragment (ie where the comment "// Do something with the time chosen by the user" is)? Set a breakpoint, run your code, pick a time and see if the breakpoint triggers. It should. Once you have confirmed this I guess it's only a matter of passing the picked time back to the activity, because that is what you want right?

    3. COYes! I think the problem is in this line: return new TimePickerDialog(getActivity(), this, hour, minute, DateFormat.is24HourFormat(getActivity())); There this is related to the default listener...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
