Дата рождения на странице регистрации, Eclipse

Question

Как я могу добавить простой календарь, который, когда пользователь нажимает на «поле даты рождения», будет перенаправлять на другую страницу или всплывающее окно с календарем, чтобы пользователь мог выбрать дату своего рождения?Я разрабатываю приложение для Android в Eclipse с PhoneGap 1.4.1, Большое спасибо, ребята.

Answer 1

Вот XML-файл

<LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content"
    android:layout_gravity="center_horizontal" android:paddingLeft="12dp"
    android:paddingRight="12dp" android:paddingTop="30dp">

    <com.wheel.WheelView android:id="@+id/day"
        android:layout_height="wrap_content" android:layout_width="46dp" />
    <com.wheel.WheelView android:id="@+id/month"
        android:layout_height="wrap_content" android:layout_width="100dp" />
    <com.wheel.WheelView android:id="@+id/year"
        android:layout_height="wrap_content" android:layout_width="wrap_content" />
</LinearLayout>

<Button android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="Set"
    android:onClick="setclick">
</Button>

Вот что я сделал:

Создание экземпляра календаря для значения по умолчанию:

//class level variables
private int mYear;
private int mMonth;
private int mDay;
static final int DATE_DIALOG_ID = 0;
private DatePickerDialog.OnDateSetListener mDateSetListener;

//inside onCreate
final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR)-20;
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH); //Default DOB is (today - 20) years

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

Функция обновления поля даты рождения EditText:

private void updateDisplay() {
    et_dob.setText(new StringBuilder().append(mMonth+1).append("/").append(mDay).append("/").append(mYear).append(" "));
    //month is 0 based so 1 is added in mMonth;
}

onClickListener on et_dob

showDialog(DATE_DIALOG_ID); //DATE_DIALOG_ID = 0;

Затем переопределите onCreateDialog в своей деятельности:

@Override
protected Dialog onCreateDialog(int id) {
    // TODO Auto-generated method stub
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this,
                    mDateSetListener,
                    mYear, mMonth, mDay);
    }
    return null;        
}

Вы должны увидеть что-то подобное, когда вы нажмете EditText et_dob.
