    <p>As I can't find a way to do this as I mentioned before, I've reached a solution by having 2 buttons (start and end) to select the dates, instead of only havin one and use a loop. After that, i created another class, and each button calls a different class.</p> <p>Declaration of the buttons and the methods "showStartDatePicker" and "showEndDatePicker":</p> <pre><code>final Button startDate = (Button)findViewById(R.id.startDate); final Button endDate = (Button)findViewById(R.id.endDate); public void showStartDatePicker(View v) { DialogFragment newFragment = new StartDatePickerFragment(); newFragment.show(getFragmentManager(), "StartDatePicker"); } public void showEndDatePicker(View v) { DialogFragment newFragment = new EndDatePickerFragment(); newFragment.show(getFragmentManager(), "EndDatePicker"); } </code></pre> <p>Class "StartDatePickerFragment":</p> <pre><code>public class StartDatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { @Override public Dialog onCreateDialog(Bundle savedInstanceState) { // Use the current date as the default date in the picker final Calendar c = Calendar.getInstance(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH); int day = c.get(Calendar.DAY_OF_MONTH); // Create a new instance of DatePickerDialog and return it return new DatePickerDialog(getActivity(), this, year, month, day); } public void onDateSet(DatePicker view, int year, int month, int day) { // Do something with the date chosen by the user Toast.makeText(getActivity(), "Fecha seleccionada: " + day + "/" + (month+1) + "/" + year, Toast.LENGTH_SHORT).show(); } } </code></pre> <p>Class "EndDatePickerFragment":</p> <pre><code>public class EndDatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { @Override public Dialog onCreateDialog(Bundle savedInstanceState) { // Use the current date as the default date in the picker final Calendar c = Calendar.getInstance(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH); int day = c.get(Calendar.DAY_OF_MONTH); // Create a new instance of DatePickerDialog and return it return new DatePickerDialog(getActivity(), this, year, month, day); } public void onDateSet(DatePicker view, int year, int month, int day) { LineGraph lineGraph = new LineGraph(); lineGraph.run(getActivity()); } } </code></pre> <p>I'm almost doing the same thing twice (creating the DatePicker), but I can't find a more efficient way.</p>

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.
