java - 日期和时间选择器问题

Question

我以前可以使用此代码，但现在由于某些奇怪的原因无法使用。

日期和时间选择器代码

btnDatePicker=(Button)view.findViewById(R.id.btn_date);
    btnTimePicker=(Button)view.findViewById(R.id.btn_time);
    txtDate=(EditText)view.findViewById(R.id.in_date);
    txtTime=(EditText)view.findViewById(R.id.in_time);

    btnDatePicker.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                              int monthOfYear, int dayOfMonth) {

                            txtDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);

                        }
                    }, mYear, mMonth, mDay);
            datePickerDialog.show();
        }
        });

    btnTimePicker.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Get Current Time
            final Calendar c = Calendar.getInstance();
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            TimePickerDialog timePickerDialog = new TimePickerDialog(getContext(),
                    new TimePickerDialog.OnTimeSetListener() {

                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            txtTime.setText(hourOfDay + ":" + minute);
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();
        }
    });

我不太确定如何修复它，它之前工作得很好，但我不知道发生了什么。我刚刚更新了 android studio，然后我的代码中的所有内容都停止工作，我尝试过清理/重建和重新同步，但仍然没有任何结果。

Answer 1

我解决了我的问题。

问题位于我的 styles.xml 文件中。我正在尝试更改应用程序的颜色，但是通过向主题添加颜色强调导致一切都崩溃了。不太清楚为什么。如果有人能解释为什么添加颜色强调会导致这样的问题，那就太好了。
