How do I create an Android spinner that open a date picker dialog?
I want a Spinner that looks like the one in the calendar app, as shown in the screenshot below.
What I've already tried:
I made a spinner in my layout XML and tried to set the onclick attribute to call a method that shows the dialog. When I put a method name in "on click", I got and error that says "The following classes could not be found: - Spinner (Change to android.widget.Spinner, Fix Build Path, Edit XML)".
<Spinner
android:id="@+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="showDatePickerDialog" />
showDatePickerDialog is in the right class:
public void showDatePickerDialog(View v) {
DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getFragmentManager(), "Date");
}
And this is DatePickerFragment (copied from another website):
import java.util.Calendar;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;
import android.widget.DatePicker;
public class DatePickerFragment 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
}
}
SOLUTION:
I found the solution at another question.
I used a regular spinner in the layout file, then in my activity class, has this code:
dateSpinner = (Spinner)findViewById(R.id.spinner_date);
View.OnTouchListener Spinner_OnTouch = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
showDatePickerDialog(v);
}
return true;
}
};
View.OnKeyListener Spinner_OnKey = new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
showDatePickerDialog(v);
return true;
}
else {
return false;
}
}
};
dateSpinner.setOnTouchListener(Spinner_OnTouch);
dateSpinner.setOnKeyListener(Spinner_OnKey);
It seems a little hacked, but it works. Does anyone know a cleaner way to do it? It would not let me setOnClickListener() or setOnItemClickListener() on the spinner.

I was able to achieve it very easily. It looks exactly like that of the calendar app :)
Use a TextView and give it a spinner style:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="@android:style/Widget.Holo.Spinner" />
For API 10 and below without the Holo Theme, use:
style="@android:style/Widget.Spinner"

A button is the best way, you just need to change the button style. I tried to set the default android spinner style to my button, but it doesn't work correctly. So I made my own style (it's a copy of the default spinner style). Here it is:
`<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false"
android:drawable="@drawable/spinner_disabled_holo_light" />
<item android:state_pressed="true"
android:drawable="@drawable/spinner_pressed_holo_light" />
<item android:state_pressed="false" android:state_focused="true"
android:drawable="@drawable/spinner_focused_holo_light" />
<item android:drawable="@drawable/spinner_default_holo_light" />
</selector>
`
The images you will find in ..\sdk\platforms\android-%%\data\res\drawable.
This works fine for me. This is a simple way to make a button spinner style, like the spinner on Google Calendar.

I think in general what people do in this case is use a button and style it like a spinner (an approach here, I think a better approach, mostly just setting the style to android.R.attr.spinnerStyle
), or they use a spinner but overload the click action to create a dialog.
Of course the hard part there is creating the custom dialog that has nice month/day/year spin-ie-things (they aren't spinners... they are kind of like slot machines or something) in them!
There's a few ways you can go about that, there is some google documentation here, and you can always just lift the android source code (although there are obviously drawbacks).
