Android应用程序中的DateTime选择器

Question

是否有任何Android小部件可以同时选择日期和时间？我已经使用了基本时间选择器和日期选择器.

但他们并不那么性感和用户友好(我发现).你知道一个包含日期和时间的小部件是否存在？非常感谢,吕克

把两者DatePicker并TimePicker在布局XML.

date_time_picker.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:padding="8dp"
    android:layout_height="match_parent">

    <DatePicker
        android:id="@+id/date_picker"
        android:layout_width="match_parent"
        android:calendarViewShown="true"
        android:spinnersShown="false"
        android:layout_weight="4"
        android:layout_height="0dp" />

    <TimePicker
        android:id="@+id/time_picker"
        android:layout_weight="4"
        android:layout_width="match_parent"
        android:layout_height="0dp" />

    <Button
        android:id="@+id/date_time_set"
        android:layout_weight="1"
        android:layout_width="match_parent"
        android:text="Set"
        android:layout_height="0dp" />

</LinearLayout>

代码:

final View dialogView = View.inflate(activity, R.layout.date_time_picker, null);
final AlertDialog alertDialog = new AlertDialog.Builder(activity).create();

dialogView.findViewById(R.id.date_time_set).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

         DatePicker datePicker = (DatePicker) dialogView.findViewById(R.id.date_picker);
         TimePicker timePicker = (TimePicker) dialogView.findViewById(R.id.time_picker);

         Calendar calendar = new GregorianCalendar(datePicker.getYear(),
                            datePicker.getMonth(),
                            datePicker.getDayOfMonth(),
                            timePicker.getCurrentHour(),
                            timePicker.getCurrentMinute());

         time = calendar.getTimeInMillis();
         alertDialog.dismiss();
    }});
alertDialog.setView(dialogView);
alertDialog.show();

Answer 2

使用此功能,您可以逐个拍摄日期和时间,然后将其设置为全局变量日期.没有图书馆没有XML.

Calendar date;
public void showDateTimePicker() {
   final Calendar currentDate = Calendar.getInstance();
   date = Calendar.getInstance();
   new DatePickerDialog(context, new DatePickerDialog.OnDateSetListener() {
       @Override
       public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            date.set(year, monthOfYear, dayOfMonth);
            new TimePickerDialog(context, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    date.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    date.set(Calendar.MINUTE, minute);
                    Log.v(TAG, "The choosen one " + date.getTime());
                }
            }, currentDate.get(Calendar.HOUR_OF_DAY), currentDate.get(Calendar.MINUTE), false).show();
       }
   }, currentDate.get(Calendar.YEAR), currentDate.get(Calendar.MONTH), currentDate.get(Calendar.DATE)).show();
}

Answer 3

Android中没有内置任何功能.

Answer 4

我创建了一个库来执行此操作.它还具有可定制的颜色!

它使用起来非常简单.

首先,您创建一个侦听器:

private SlideDateTimeListener listener = new SlideDateTimeListener() {

    @Override
    public void onDateTimeSet(Date date)
    {
        // Do something with the date. This Date object contains
        // the date and time that the user has selected.
    }

    @Override
    public void onDateTimeCancel()
    {
        // Overriding onDateTimeCancel() is optional.
    }
};

然后创建并显示对话框:

new SlideDateTimePicker.Builder(getSupportFragmentManager())
    .setListener(listener)
    .setInitialDate(new Date())
    .build()
    .show();

希望对你有帮助.

在DatePicker更新时间方法中调用时间选择器对话框.它不会同时被调用,但是当你按下DatePicker设置按钮时.时间选择器对话框将打开.该方法如下.

package com.android.date;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;

public class datepicker extends Activity {

    private TextView mDateDisplay;
    private Button mPickDate;
    private int mYear;
    private int mMonth;
    private int mDay;
    private TextView mTimeDisplay;
    private Button mPickTime;

    private int mhour;
    private int mminute;

    static final int TIME_DIALOG_ID = 1;

    static final int DATE_DIALOG_ID = 0;

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

        mDateDisplay =(TextView)findViewById(R.id.date);
        mPickDate =(Button)findViewById(R.id.datepicker);
        mTimeDisplay = (TextView) findViewById(R.id.time);
        mPickTime = (Button) findViewById(R.id.timepicker);

        //Pick time's click event listener
        mPickTime.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {
                showDialog(TIME_DIALOG_ID);
            }
        });

        //PickDate's click event listener 
        mPickDate.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                showDialog(DATE_DIALOG_ID);
            }
        });

        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);
        mhour = c.get(Calendar.HOUR_OF_DAY);
        mminute = c.get(Calendar.MINUTE);
    }

    //-------------------------------------------update date---//    
    private void updateDate() {
        mDateDisplay.setText(
            new StringBuilder()
                    // Month is 0 based so add 1
                    .append(mDay).append("/")
                    .append(mMonth + 1).append("/")
                    .append(mYear).append(" "));
        showDialog(TIME_DIALOG_ID);
    }

      //-------------------------------------------update time---//    
    public void updatetime() {
        mTimeDisplay.setText(
                new StringBuilder()
                        .append(pad(mhour)).append(":")
                        .append(pad(mminute))); 
    }

    private static String pad(int c) {
        if (c >= 10)
            return String.valueOf(c);
        else
            return "0" + String.valueOf(c);


    //Datepicker dialog generation  

    private DatePickerDialog.OnDateSetListener mDateSetListener =
        new DatePickerDialog.OnDateSetListener() {

            public void onDateSet(DatePicker view, int year, 
                                  int monthOfYear, int dayOfMonth) {
                mYear = year;
                mMonth = monthOfYear;
                mDay = dayOfMonth;
                updateDate();
            }
        };


     // Timepicker dialog generation
        private TimePickerDialog.OnTimeSetListener mTimeSetListener =
            new TimePickerDialog.OnTimeSetListener() {
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    mhour = hourOfDay;
                    mminute = minute;
                    updatetime();
                }
            };

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

            case TIME_DIALOG_ID:
                return new TimePickerDialog(this,
                        mTimeSetListener, mhour, mminute, false);

            }
            return null;
        }
}

main.xml如下所示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="@string/hello"/>

    <TextView android:id="@+id/time"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""/>

    <Button
        android:id="@+id/timepicker"
        android:text="Change Time" 
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content"/>

    <TextView 
        android:id="@+id/date"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""/>

    <Button android:id="@+id/datepicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="200dp"
        android:text="Change the date"/>

</LinearLayout>

Answer 6

您链接的URL显示如何使用时间选择器弹出对话框以及使用日期选择器弹出另一个对话框.但是,您需要注意,您可以直接在自己的布局中使用这些UI小部件.您可以构建自己的对话框,在同一视图中同时包含TimePicker和DatePicker,从而完成我认为您正在寻找的内容.

换句话说,不要使用TimePickerDialog和DatePickerDialog,只需在自己的对话框或活动中直接使用UI小部件TimePicker和DatePicker.

Answer 7

我还想组合一个DatePicker和一个TimePicker.所以我创建了一个API来处理一个界面!:)

https://github.com/Kunzisoft/Android-SwitchDateTimePicker

您也可以使用SublimePicker

Answer 8

我在我的一个项目中遇到了同样的问题,并决定在一个用户友好的对话框中创建一个具有日期和时间选择器的自定义小部件.您可以在http://code.google.com/p/datetimepicker/上获取源代码以及示例.该代码在Apache 2.0下获得许可.

Answer 9

我分叉,更新,重构和mavenized android-datelider项目.它现在在Github上:

Answer 10

您可以使用DatePicker library wdullaer/MaterialDateTimePicker 之一

• 首先显示DatePicker。

  private void showDatePicker() {
  Calendar now = Calendar.getInstance();
  DatePickerDialog dpd = DatePickerDialog.newInstance(
          HomeActivity.this,
          now.get(Calendar.YEAR),
          now.get(Calendar.MONTH),
          now.get(Calendar.DAY_OF_MONTH)
  );
  dpd.show(getFragmentManager(), "Choose Date:");
  }
  

• 然后 onDateSet callback store date & show TimePicker

  @Override
  public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
  Calendar cal = Calendar.getInstance();
  cal.set(year, monthOfYear, dayOfMonth);
  filter.setDate(cal.getTime());
  new Handler().postDelayed(new Runnable() {
      @Override
      public void run() {
          showTimePicker();
      }
  },500);
  }
  

• 到onTimeSet callback店时间

   @Override
   public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute) {
  Calendar cal = Calendar.getInstance();
  if(filter.getDate()!=null)
      cal.setTime(filter.getDate());
  cal.set(Calendar.HOUR_OF_DAY,hourOfDay);
  cal.set(Calendar.MINUTE,minute);
  }
