Selector de fecha en Android

Question

¿Puede uno publicar código de ejemplo 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

Uso del DatePicker

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

Es dotados desde el API de nivel 1

Aquí un ejemplo de cómo utilizar la DatePickerDialog.

Primero se debe agregar un TextView y un botón para 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"/> 

siguiente que tiene que inicializar el botón de Vista de Texto y en el método onCreate de su diseño. Es necesario este variables de 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 ayuda, lo usó y funciona bien.

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

Answer 5

La respuesta aceptada no lo hace manejar al usuario haciendo clic en cancelar en th e selector de fecha. En ese caso, nada debe actualizarse.

Yo quería lo mismo que OP, pero solo quería que estuviera en línea. Esto es lo que solía:

Crear la devolución de llamada que se llama cuando se hace clic en el botón selector de fechas OK:

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

A continuación, utilice el código siguiente en el método en el que se 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 6

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" /> 

Answer 7

uso: import java.util.Calendario;

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

este paquete solo es compatible con API de nivel 24 no inferior a eso. Este es el paquete que necesitamos usar para obtener el calendario en el cuadro de diálogo,

esto funciona bien.
