Selector de fecha en Android

Question

¿Se puede publicar un código de muestra para un selector de fecha simple en Android?

Si el selector de fecha no es posible en Android, se necesita una opción para elegir una fecha.

Answer 1

Aquí hay una versión actualizada que documenta la compatibilidad hacia atrás con la biblioteca de soporte:

http://developer.android.com/guide/topics/ui/controls/pickers.html#DatePicker

Answer 2

La respuesta aceptada no controla al usuario que hace clic en Cancelar en el selector de fecha. En ese caso, nada debe ser actualizado.

Quería lo mismo que OP, pero solo lo quería en línea. Esto es lo que usé:

Cree la devolución de llamada que se llamará cuando se haga clic en el botón Aceptar del selector de fecha:

public void datePicked(int year, int month, int day) {
    buttonDate.setText(String.valueOf(year) + "/" + 
          String.valueOf(month) + "/" + String.valueOf(day));
}

Luego use el siguiente código en el método donde crea un botón para elegir la fecha:

    buttonDate = (Button) rootView.findViewById(R.id.button_select_date);
    buttonDate.setText("Select Date");
    buttonDate.setOnClickListener(new View.OnClickListener() {
        public void setReturnDate(int year, int month, int day) {
            datePicked(year, month, day);
        }

        @Override
        public void onClick(View v) {
            Dialog datePickerDialog = new DatePickerDialog(activity, new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

                }
            }, leagueEndDate.get(Calendar.YEAR), leagueEndDate.get(Calendar.MONTH), leagueEndDate
                    .get(Calendar.DAY_OF_MONTH));
            datePickerDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(DialogInterface dialog) {
                    setReturnDate(((DatePickerDialog) dialog).getDatePicker().getYear(),
                            ((DatePickerDialog) dialog).getDatePicker().getMonth(), ((DatePickerDialog) dialog)
                                    .getDatePicker().getDayOfMonth());
                }
            });
            datePickerDialog.show();
        }
    });

Answer 3

Usa el Selector de fechas

http://developer.android.com/reference/android/widget/DatePicker.html

Está disponible desde API Nivel 1.

Aquí un ejemplo de cómo usar el DatePickerDialog.

Primero agregue un TextView y un botón a su layout.xml

<Button android:id="@+id/myDatePickerButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Choose Date"/>

<TextView android:id="@+id/showMyDate"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"/>

A continuación, debe inicializar Button y TextView en el Método onCreate de su diseño. Necesitas las variables de esta clase.

private int mYear;
private int mMonth;
private int mDay;

private TextView mDateDisplay;
private Button mPickDate;

static final int DATE_DIALOG_ID = 0;

Aquí el método onCreate

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mDateDisplay = (TextView) findViewById(R.id.showMyDate);        
    mPickDate = (Button) findViewById(R.id.myDatePickerButton);

    mPickDate.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            showDialog(DATE_DIALOG_ID);
        }
    });

    // get the current date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    // display the current date
    updateDisplay();
}

Método UpdateDisplay:

private void updateDisplay() {
    this.mDateDisplay.setText(
        new StringBuilder()
                // Month is 0 based so add 1
                .append(mMonth + 1).append("-")
                .append(mDay).append("-")
                .append(mYear).append(" "));
}

El oyente de devolución de llamada para el DatePickDialog

private DatePickerDialog.OnDateSetListener mDateSetListener =
    new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker view, int year, 
                              int monthOfYear, int dayOfMonth) {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            updateDisplay();
        }
    };

El método onCreateDialog, llamado por showDialog ()

@Override
protected Dialog onCreateDialog(int id) {
   switch (id) {
   case DATE_DIALOG_ID:
      return new DatePickerDialog(this,
                mDateSetListener,
                mYear, mMonth, mDay);
   }
   return null;
}

Espero que ayude, lo use y funcione bien.

Answer 4

uso: import java.util.Calendar;

en su lugar: importar android.icu.util.Calendar.

este paquete soporta solo para API nivel-24 no menos que eso. Este es el paquete que debemos usar para obtener el calendario en el cuadro de diálogo,

esto funciona bien

Answer 7

Step 1 : create a java file:

package com.example.babs;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import  android.app.FragmentManager;


public class EditUserInfo extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.user_edit_view);

    }

    public class DatePickerFragment extends DialogFragment
    implements DatePickerDialog.OnDateSetListener {


        // pgrm mark ---- ---- ----- ---- ---- ----- ---- ---- -----  ---- ---- -----

        @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
        }

    }


    public void showDatePickerDialog(View v) {

        FragmentManager fragmentManager = getFragmentManager();

        DialogFragment newFragment = new DatePickerFragment();
        newFragment.show(fragmentManager, "datePicker");
    }

}// end main class EditUserInfo

step 2: your xml file must contain : 

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    android:fillViewport="true" >
</ScrollView>
<Button 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:text="@string/pick_date" 
    android:onClick="showDatePickerDialog" />
