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，然后用戶可以設置時間

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) {

}

}
