Android 日期和时间的使用
日期和时间的使用;
1:弹出框TimePickerDialog,DatePickerDialog
2:组件TimePicker,DatePicker
TimePickerDialog的使用:通过点击button显示图一,然后用户可以设置时间
DatePickerDialog的使用只需要将TimePickerDialog修改成DatePickerDialog, TimePickerDialog.OnTimeSetListener 分别修改成DatePickerDialog,OnDateSetListener既可
public static class TimePickerFragment extends DialogFragment
implements TimePickerDialog.OnTimeSetListener {
//用户创建弹出时间框的方法
@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的代码:
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
//用户创建日期对话框的时间方法
@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) {
}
}
