异常：android.view.InflateException：二进制 XML 文件第 20 行：膨胀类 net.simonvt.datepicker.DatePicker 时出错

Question

由于向后兼容，我正在使用 simonvt datepicker 库的 android 应用程序，但我在开发人员控制台崩溃报告中看到有 3 份报告针对相同的错误，但我在我的设备上尝试过这样的工作这真的很奇怪。

请支持为什么它如此奇怪并且有时会出现异常。

OnDateSetListener date = new OnDateSetListener() {

    private void updateLabel() {

        String myFormat = "EEE, dd MMM"; // In which you need put here
        String myDbFormat = "dd/MM/yyyy";
        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
        SimpleDateFormat DBsdf = new SimpleDateFormat(myDbFormat, Locale.US);
        Departure_date = sdf.format(myCalendar.getTime());
        Departure_date_url = DBsdf.format(myCalendar.getTime());

        Log.i("Departure_date", Departure_date);
        date_btn.setText(sdf.format(myCalendar.getTime()));
    }

    @Override
    public void onDateSet(net.simonvt.datepicker.DatePicker view, int year,
            int monthOfYear, int dayOfMonth) {
        myCalendar.set(Calendar.YEAR, year);
        myCalendar.set(Calendar.MONTH, monthOfYear);
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        updateLabel();
    }
};

final net.simonvt.datepicker.DatePickerDialog dpd = new net.simonvt.datepicker.DatePickerDialog(
                            getActivity(), date, myCalendar.get(Calendar.YEAR),
                            myCalendar.get(Calendar.MONTH), myCalendar
                                    .get(Calendar.DAY_OF_MONTH));

Answer 1

我注意到simonvt datepicker 中有一些错误是导致异常的原因。我再次转到DatePicker，android 提供的功能非常棒，没有任何例外。
