Android时间选择器显示两个时钟？

Question

我根据android dev doc实现了Android时间选择器，一切正常，但我有一个奇怪的错误。我搜索了很多，没有找到任何东西，我在这里问。

这是我的时间选择器：

以下是代码：

 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
            if (hourOfDay < 10) {
                startTime.setText("0" + Integer.toString(hourOfDay) + ":" + Integer.toString(minute));
            } else if (minute < 10) {
                startTime.setText(Integer.toString(hourOfDay) + ":0" + Integer.toString(minute));
            } else if (hourOfDay < 10 && minute < 10) {
                startTime.setText("0" + Integer.toString(hourOfDay) + ":0" + Integer.toString(minute));
            } else if (minute == 0) {
                startTime.setText(Integer.toString(hourOfDay) + ":00");
            } else
                startTime.setText(Integer.toString(hourOfDay) + ":" + Integer.toString(minute));
        }
    }

有谁知道如何解决这个问题？

Answer 1

TimePickerDialog (Context context, 
            int themeResId, 
            TimePickerDialog.OnTimeSetListener listener, 
            int hourOfDay, 
            int minute, 
            boolean is24HourView)

is24HourView ：这是24小时视图还是上午/下午。

尝试将此参数设置为 false ，我想你会得到你想要的。

我在三星设备（我的情况下为Galaxy S5和S6）上遇到了同样的问题。我发现在此设备上标题是由系统添加的，要隐藏该标题，您所需要做的就是自行设置为null。

TimePickerDialog dialog = new TimePickerDialog(getActivity(), this, hour, minute, false);
dialog.setTitle(null);
