推荐答案
得到冰淇淋三明治风格的日期选择器的最简单方法是使用的 ActionBarSherlock库。
The easiest way to get the ice cream sandwich styled date picker is by using the ActionBarSherlock library.
然后创建对话框类:
public class DatePickerFragment extends SherlockDialogFragment implements android.app.DatePickerDialog.OnDateSetListener {
private OnFragmentClickListener mListener;
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mListener = (OnFragmentClickListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString() + " must implement listeners!");
}
}
@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 onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// Do something with the date chosen by the user
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, monthOfYear);
c.set(Calendar.DAY_OF_MONTH, dayOfMonth);
mListener.onFragmentClick(DialogDemonstrationActivity.DATE_PICKER_ACTION, c);
}
}
活动监听器类:
The activity listener class:
public interface OnFragmentClickListener {
public void onFragmentClick(int action, Object object);
}
该对话框可以与你的活动下启动:
The dialog can be launched with following from your activity:
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
// Create and show the dialog.
DatePickerFragment newFragment = new DatePickerFragment();
newFragment.show(ft, null);
您的活动则必须实现监听,你是启动和运行。
Your activity then have to implement the listener and you are up and running.
