问题
I am looking for a CalendarView that can be used in a dialog something like this:
I plan to use android.widget.CalendarView but it is available from API level 11. That's an issue considering there are still lot of users, using android 2.3.3 (but not a major one can let go those set of user).
Which of these options should I use?
1) libraries that are available and use them accordingly.
2) customize the android.widget.CalendarView?
If #2, then are there any examples for it?

when you will visit
https://github.com/derekbrameyer/android-betterpickers
For a working implementation of this project see the sample/ folder.
Implement the appropriate Handler callbacks:
public class MyActivity extends Activity implements DatePickerDialogFragment.DatePickerDialogHandler {
@Override
public void onCreate(Bundle savedInstanceState) {
// ...
}
@Override
public void onDialogDateSet(int year, int monthOfYear, int dayOfMonth) {
// Do something with your date!
}
}
Use one of the Builder classes to create a PickerDialog with a theme:
DatePickerBuilder dpb = new DatePickerBuilder()
.setFragmentManager(getSupportFragmentManager())
.setStyleResId(R.style.BetterPickersDialogFragment);
dpb.show();
also for an another example you can visit
https://github.com/roomorama/Caldroid
and use as follows
To embed the caldroid fragment in your activity, use below code:
CaldroidFragment caldroidFragment = new CaldroidFragment();
Bundle args = new Bundle();
Calendar cal = Calendar.getInstance();
args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
caldroidFragment.setArguments(args);
FragmentTransaction t = getSupportFragmentManager().beginTransaction();
t.replace(R.id.calendar1, caldroidFragment);
t.commit();
