Ho do I Hour and the Minute Value in the Fragment，我在其中启动了这个 Timepicker：
public static class TimePickerFragment extends DialogFragment
implements TimePickerDialog.OnTimeSetListener {
@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
}
}
我在片段中使用此代码进行了尝试：
TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
Log.i("",""+hourOfDay+":"+minute);
textview.setText(""+hourOfDay+":"+minute);
}
};
但它确实设置了任何东西
您能帮我从 Timepicker 中获取值吗？
