copied!<p>I have a solution that allows for an unlimited number of date fields without adding new dialog types. When the user clicks one of the buttons, I register which TextView and Calendar is currently being modified before launching the DatePickerDialog. The dialog's OnDateSetListener then updates the registered TextView and Calendar.</p> <pre><code>import java.util.Calendar; import android.app.Activity; import android.app.DatePickerDialog; import android.app.Dialog; import android.app.DatePickerDialog.OnDateSetListener; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.DatePicker; import android.widget.TextView; public class MultiDatePickerActivity extends Activity { private TextView startDateDisplay; private TextView endDateDisplay; private Button startPickDate; private Button endPickDate; private Calendar startDate; private Calendar endDate; static final int DATE_DIALOG_ID = 0; private TextView activeDateDisplay; private Calendar activeDate; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.multidatepicker); /* capture our View elements for the start date function */ startDateDisplay = (TextView) findViewById(R.id.startDateDisplay); startPickDate = (Button) findViewById(R.id.startPickDate); /* get the current date */ startDate = Calendar.getInstance(); /* add a click listener to the button */ startPickDate.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { showDateDialog(startDateDisplay, startDate); } }); /* capture our View elements for the end date function */ endDateDisplay = (TextView) findViewById(R.id.endDateDisplay); endPickDate = (Button) findViewById(R.id.endPickDate); /* get the current date */ endDate = Calendar.getInstance(); /* add a click listener to the button */ endPickDate.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { showDateDialog(endDateDisplay, endDate); } }); /* display the current date (this method is below) */ updateDisplay(startDateDisplay, startDate); updateDisplay(endDateDisplay, endDate); } private void updateDisplay(TextView dateDisplay, Calendar date) { dateDisplay.setText( new StringBuilder() // Month is 0 based so add 1 .append(date.get(Calendar.MONTH) + 1).append("-") .append(date.get(Calendar.DAY_OF_MONTH)).append("-") .append(date.get(Calendar.YEAR)).append(" ")); } public void showDateDialog(TextView dateDisplay, Calendar date) { activeDateDisplay = dateDisplay; activeDate = date; showDialog(DATE_DIALOG_ID); } private OnDateSetListener dateSetListener = new OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { activeDate.set(Calendar.YEAR, year); activeDate.set(Calendar.MONTH, monthOfYear); activeDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); updateDisplay(activeDateDisplay, activeDate); unregisterDateDisplay(); } }; private void unregisterDateDisplay() { activeDateDisplay = null; activeDate = null; } @Override protected Dialog onCreateDialog(int id) { switch (id) { case DATE_DIALOG_ID: return new DatePickerDialog(this, dateSetListener, activeDate.get(Calendar.YEAR), activeDate.get(Calendar.MONTH), activeDate.get(Calendar.DAY_OF_MONTH)); } return null; } @Override protected void onPrepareDialog(int id, Dialog dialog) { super.onPrepareDialog(id, dialog); switch (id) { case DATE_DIALOG_ID: ((DatePickerDialog) dialog).updateDate(activeDate.get(Calendar.YEAR), activeDate.get(Calendar.MONTH), activeDate.get(Calendar.DAY_OF_MONTH)); break; } } } </code></pre> <p>This kind of flexibility is useful in an application where you don't know how many date pickers you will need until runtime.</p>
