我使用datepickerdialog简单的Activity..并且当DialogBox关闭时,下面的方法将被调用2次.

private void FetchData(String day, String month, int year)

我不知道为什么这个方法在DatepickerDialog只显示1次时会调用2次？

public class MainActivity extends Activity {
ListView listview;
Cursor smscursor;
SMS_SQL sql;
ListAdapter adapter;
final ArrayList<List> list = new ArrayList<List>();
private int year;
private int month;
String monthstr;
private int day;
String dayday, monthmonth;
ArrayList<String> smslist = new ArrayList<String>();
String PhoneNo = "1234567890";
static final int DATE_DIALOG_ID = 999;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) { …

我非常惊讶,即使在搜索1小时后我也无法在网上找到它!

我有一个日期选择器对话框,从原始的Pickers示例略微修改(感谢Raghunandan 为此).

但我不想将默认日期设置为当前日期,而是应该从EditText中选择日期并将该日期设置为datepickerdialog.有人可以帮我解决这个问题吗？我目前的代码如下.

编辑我需要知道如何从DatePickerFragment类中访问EditText datepurchased的值.

主类:

public class EditEntry extends Activity  implements DatePickerFragment.TheListener{
    EditText edit_datepurchased;
public void showdate(View v) {
        edit_datepurchased = (EditText) findViewById(v.getId());
        DialogFragment newFragment = new DatePickerFragment();
        newFragment.show(getFragmentManager(), "datePicker");
    }
public void returnDate(String date) {
        edit_datepurchased.setText(date);
    }
}

DatePickerFragment CLASS:

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
    TheListener listener;

    public interface TheListener{
        public void returnDate(String date);
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){

        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);
        listener = (TheListener) …

我使用 DatePickerDialog 允许用户选择一天。

Calendar calendar = Calendar.getInstance();
calendar.setFirstDayOfWeek(Calendar.TUESDAY);
new DatePickerDialog(this, dateListener, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)).show();

我使用setFirstDayOfWeek方法将一周的开始日期设置为星期二，但对话框选择器始终在左侧显示星期一。

如何为 DatePickerDialog 设置一周的开始日期？

这个问题描述了如何使用DatePicker小部件来完成它,但我没有这样的东西.

我有这些:

@Override
protected Dialog onCreateDialog(int id)
{

    switch (id)
    {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear1, mMonth1, mDay1);
    case DATE_DIALOG_ID_2:
        return new DatePickerDialog(this, mDateSetListener2, mYear2, mMonth2, mDay2);
    case DATE_DIALOG_ID_3:
        return new DatePickerDialog(this, mDateSetListener3, mYear3, mMonth3, mDay3);
    }
    return null;
}


protected void onPrepareDialog(int id, Dialog dialog)
{

    switch (id)
    {
    case DATE_DIALOG_ID:
        ((DatePickerDialog) dialog).updateDate(mYear1, mMonth1, mDay1);
        break;
    case DATE_DIALOG_ID_2:
        ((DatePickerDialog) dialog).updateDate(mYear2, mMonth2, mDay2);
        break;
    case DATE_DIALOG_ID_3:
        ((DatePickerDialog) dialog).updateDate(mYear3, mMonth3, mDay3);
        break;
    }
}

然后3 DatePickerDialog.OnDateSetListener() š

这些DatePickerDialogs上没有setMax()或setMin(). …

我有两个ImageButtons.一个负责设置开始日期,另一个负责设置结束日期.按下每个按钮时,它们会显示一个DatePickerDialog.onCreateDialog方法在另一个类中.这是班级:

DatePickerFragment.Java

package com.ThatOneNoob.smarthaul;

import java.util.Calendar;

import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;
import android.widget.DatePicker;


public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

@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);
}


@Override
public void …

当我按下按钮显示DatePickerDialog时,对话框显示一个月更大.例如,如果我使用这样的当前日期(使用joda库的DateTime)启动:

   DateTimeZone zone = DateTimeZone.forID("Europe/Athens");

   DateTime dt = new DateTime(zone);


   int year = dt.getYear();
   int month = dt.getMonthOfYear();
   int day = dt.getDayOfMonth();

这是2014年7月7日,日期对话框显示更大的一个月07/09/2014.我不明白为什么会这样.

表示datePickerFragment的片段是:

 @SuppressLint("ValidFragment")
    public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{

        @SuppressLint("ValidFragment")
        TextView txtDate;
        GlobalData appState;


         public DatePickerFragment(TextView txtDate) {
            super();
            this.txtDate = txtDate;
        }

        @Override
            public Dialog onCreateDialog(Bundle savedInstanceState) {
                // Use the current date as the default date in the picker
                DateTimeZone zone = DateTimeZone.forID("Europe/Athens");
                DateTime dt = new DateTime(zone);

                int year = dt.getYear();
                int month = …

我想在用户点击时获取日期选择器对话框的当前日期,但它不起作用.我的默认日期未更改为当前日期.我的代码中我做错了什么？

            Calendar mcurrentDate = Calendar.getInstance();

            int day   = mcurrentDate.get(Calendar.DAY_OF_MONTH);
            int month = mcurrentDate.get(Calendar.MONTH);
            int year  = mcurrentDate.get(Calendar.YEAR);

            DatePickerDialog dpd;
            dpd = new DatePickerDialog(getActivity(), 0,
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int month, int day) {
                            // TODO Auto-generated method stub
                            dateTxtVu.setText("Date: " + day + "-" + month
                                    + "-" + year);
                            dateStr = day + "-" + month + "-" + year;
                        }

                    }, day, month, year);
            dpd.show();

我有一个带有一些自定义组件的模块。其中一个里面有一个 DatePickerDialog。我需要为这些使用自定义强调色。如何从主应用程序样式中检索颜色？有没有办法使用相同的样式避免循环引用？否则，有一种方法可以以编程方式设置 DatePickerDialog 的强调色吗？

在我的应用程序中，我必须显示 4-5 个日期选择器并设置日期如何使用 datepicker Dialog fragment 执行此操作？

目前我必须为所有日期选择器对话框制作单独的日期选择器...

 public static class RegistrationDatePicker extends DialogFragment
        implements DatePickerDialog.OnDateSetListener {

    @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);

        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
        dialog.getDatePicker().setMaxDate(new Date().getTime());
        return dialog;
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        mTextView.setText(String.valueOf(month + "/" …
