Calendario personalizado de Android

Question

Estoy buscando un CalendarView que se pueda usar en un diálogo como este:

Planeo usar android.widget.CalendarView pero está disponible desde el nivel 11 de la API. Eso es un problema considerando que todavía hay muchos usuarios, usando Android 2.3.3 (pero ninguno importante puede dejar ir a ese conjunto de usuarios).

¿Cuál de estas opciones debo usar?

1) Las bibliotecas que están disponibles y las utilizan en consecuencia.

2) personalizar el android.widget.CalendarView ?

Si # 2, entonces ¿hay algún ejemplo para ello?

Answer 1

Espero que esto te ayude, esto es todo el calendario personalizado editable que puedes editar a tu manera

cuando vas a visitar

https://github.com/derekbrameyer/android-betterpickers

Para una implementación de trabajo de este proyecto vea la muestra / carpeta.

Implementar las devoluciones de llamada del controlador apropiado:

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!
}
}

Utilice una de las clases de Builder para crear un PickerDialog con un tema:

DatePickerBuilder dpb = new DatePickerBuilder()
.setFragmentManager(getSupportFragmentManager())
.setStyleResId(R.style.BetterPickersDialogFragment);
dpb.show();

También para otro ejemplo puedes visitar.

https://github.com/roomorama/Caldroid

y usar de la siguiente manera

Para insertar el fragmento de caldroid en su actividad, use el siguiente código:

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();
