Android 日期和時間的使用實例詳解

Android 日期和時間的使用

日期和時間的使用；

1：彈出框TimePickerDialog,DatePickerDialog

2：組件TimePicker,DatePicker

TimePickerDialog的使用：通過點擊button顯示圖一，然後用戶可以設置時間

DatePickerDialog的使用只需要將TimePickerDialog修改成DatePickerDialog, TimePickerDialog.OnTimeSetListener 分別修改成DatePickerDialog,OnDateSetListener既可

public static class TimePickerFragment extends DialogFragment
              implements TimePickerDialog.OnTimeSetListener {
    //用戶創建彈出時間框的方法
  @Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current time as the default values for the picker
    final Calendar c = Calendar.getInstance();
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int minute = c.get(Calendar.MINUTE);

    // Create a new instance of TimePickerDialog and return it
    return new TimePickerDialog(getActivity(), this, hour, minute,
        DateFormat.is24HourFormat(getActivity()));
  }

  public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
    // Do something with the time chosen by the user
  }
}
 
  

 android:layout_width="wrap_content" 
  android:layout_height="wrap_content"
  android:text="@string/pick_time" 
  android:onClick="showTimePickerDialog" />

public void showTimePickerDialog(View v) {
  DialogFragment newFragment = new TimePickerFragment();
  newFragment.show(getSupportFragmentManager(), "timePicker");
}

DatePickerDialog的代碼：

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

  //用戶創建日期對話框的時間方法
  @Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {

    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);
    return dialog;
  }



  @Override
  public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {



  }

}
