无法将Android时间选择器模式24小时模式更改为AM_PM模式

Question

我在这里使用timepicker Dialouge，但是由于某些我不了解的原因，我无法将time picker的模式更改为AM_PM mode我尝试了代码timepicker.setIs24HourView(false); 这是我的代码

onCreate(..){
button.onClickListe..(new...(){
showTimePickerDialog();
});}


 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
        return new TimePickerDialog(getActivity(), this, hour, minute,
                true);
    }

    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
       view.setIs24HourView(false);//TODO not working <-------- This code is not working here
        setTimeString(hourOfDay, minute, 0);

        timeView.setText(timeString);
    }
}


`private void showTimePickerDialog() {
    DialogFragment newFragment = new TimePickerFragment();
    newFragment.show(getFragmentManager(), "timePicker");
}`}

检查TimePickerDialog构造函数中的最后一个参数是否为24小时格式，因此禁用24小时格式，并为最后一个参数传递false值：

return new TimePickerDialog(getActivity(), this, hour, minute,false);
