Question

我知道这是一个愚蠢的问题，但我在Android开发方面真的很新。我已经按照关于在这个网站Create an Alarm Clock in Android上做一个简单警报的教程，但我认为autor忘了编写一些变量行，因为我在每一行中都有alarmDetails cannot resolve as a variable这样的几行中出现错误{{1 }}。我不知道该行的变量类型是什么，这里是完整的代码：

更新问题已解决，但我收到了另一个错误：alarmDetails。我认为这是同样的问题，一些代码没有放在教程上。这是我的班级alarmTone cannot resolve as a field

的代码

AlarmDetailsActivity

和类AlarmModel

的代码

        getActionBar().setDisplayHomeAsUpEnabled(true);

    final LinearLayout ringToneContainer = (LinearLayout) findViewById(R.id.alarm_ringtone_container);
    ringToneContainer.setOnClickListener(new OnClickListener(){

            case R.id.action_save_alarm_details:{

                finish();
            }

        return super.onOptionsItemSelected(item);
    }


    private void updateModelFromLayout() {

    TimePicker timePicker = (TimePicker) findViewById(R.id.alarm_details_time_picker);
    alarmDetails.timeMinute = timePicker.getCurrentMinute().intValue();
    alarmDetails.timeHour = timePicker.getCurrentHour().intValue();

    EditText edtName = (EditText) findViewById(R.id.alarm_details_name);
    alarmDetails.name = edtName.getText().toString();

    CheckBox chkWeekly = (CheckBox) findViewById(R.id.alarm_details_repeat_weekly);
    alarmDetails.repeatWeekly = chkWeekly.isChecked();

    CheckBox chkSunday = (CheckBox) findViewById(R.id.alarm_details_repeat_sunday);
    alarmDetails.setRepeatingDay(AlrmModel.SUNDAY, chkSunday.isChecked());

    CheckBox chkMonday = (CheckBox) findViewById(R.id.alarm_details_repeat_monday);
    alarmDetails.setRepeatingDay(AlrmModel.MONDAY, chkMonday.isChecked());

    CheckBox chkTuesday = (CheckBox) findViewById(R.id.alarm_details_repeat_tuesday);
    alarmDetails.setRepeatingDay(AlrmModel.TUESDAY, chkTuesday.isChecked());

    CheckBox chkWednesday = (CheckBox) findViewById(R.id.alarm_details_repeat_wednesday);
    alarmDetails.setRepeatingDay(AlrmModel.WEDNESDAY, chkWednesday.isChecked());

    CheckBox chkThursday = (CheckBox) findViewById(R.id.alarm_details_repeat_thursday);
    alarmDetails.setRepeatingDay(AlrmModel.THURSDAY, chkThursday.isChecked());

    CheckBox chkFriday = (CheckBox) findViewById(R.id.alarm_details_repeat_friday);
    alarmDetails.setRepeatingDay(AlrmModel.FRIDAY, chkFriday.isChecked());

    CheckBox chkSaturday = (CheckBox) findViewById(R.id.alarm_details_repeat_saturday);
    alarmDetails.setRepeatingDay(AlrmModel.SATURDAY, chkSaturday.isChecked());

    alarmDetails.isEnabled = true;
}


}

我该怎么办？

Answer 1

尝试使用AlarmModel：在教程中，AlarmModel中的变量似乎与alarmDetails的变量匹配

报警教程：alarmDetails无法解析为变量
