    <p>I have a fragment that opens a <code>Dialogfragment</code> to get user input (a string, and an integer). How do I send these two things back to the fragment?</p> <p>Here is my DialogFragment:</p> <pre><code>public class DatePickerFragment extends DialogFragment { String Month; int Year; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { getDialog().setTitle(getString(R.string.Date_Picker)); View v = inflater.inflate(R.layout.date_picker_dialog, container, false); Spinner months = (Spinner) v.findViewById(R.id.months_spinner); ArrayAdapter&lt;CharSequence&gt; monthadapter = ArrayAdapter.createFromResource(getActivity(), R.array.Months, R.layout.picker_row); months.setAdapter(monthadapter); months.setOnItemSelectedListener(new OnItemSelectedListener(){ @Override public void onItemSelected(AdapterView&lt;?&gt; parentView, View selectedItemView, int monthplace, long id) { Month = Integer.toString(monthplace); } public void onNothingSelected(AdapterView&lt;?&gt; parent) { } }); Spinner years = (Spinner) v.findViewById(R.id.years_spinner); ArrayAdapter&lt;CharSequence&gt; yearadapter = ArrayAdapter.createFromResource(getActivity(), R.array.Years, R.layout.picker_row); years.setAdapter(yearadapter); years.setOnItemSelectedListener(new OnItemSelectedListener(){ @Override public void onItemSelected(AdapterView&lt;?&gt; parentView, View selectedItemView, int yearplace, long id) { if (yearplace == 0){ Year = 2012; }if (yearplace == 1){ Year = 2013; }if (yearplace == 2){ Year = 2014; } } public void onNothingSelected(AdapterView&lt;?&gt; parent) {} }); Button button = (Button) v.findViewById(R.id.button); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { getDialog().dismiss(); } }); return v; } } </code></pre> <p>I need to send the data after the button click and before <code>getDialog().dismiss()</code></p> <p>Here is the fragment that data needs to be sent to:</p> <pre><code>public class CalendarFragment extends Fragment { int Year; String Month; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { super.onCreate(savedInstanceState); int position = getArguments().getInt("position"); String[] categories = getResources().getStringArray(R.array.categories); getActivity().getActionBar().setTitle(categories[position]); View v = inflater.inflate(R.layout.calendar_fragment_layout, container, false); final Calendar c = Calendar.getInstance(); SimpleDateFormat month_date = new SimpleDateFormat("MMMMMMMMM"); Month = month_date.format(c.getTime()); Year = c.get(Calendar.YEAR); Button button = (Button) v.findViewById(R.id.button); button.setText(Month + " "+ Year); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { new DatePickerFragment().show(getFragmentManager(), "MyProgressDialog"); } }); return v; } } </code></pre> <p>so once the user selects a date in the <code>Dialogfragment</code>, it must return the month and year. </p> <p>Then, the text on the button should change to the month and year specified by user.</p>

Guidance
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.
