其余的在Android应用程序？ [英] remainder in android application?

问题描述

我想创建余，我已经试过这种code，但不能正常工作，如果我设置报警它没有给予任何回应

下面是MainActivity.java

 包com.example.ltr_3.dtrem;
公共类MainActivity延伸活动{
    TimePicker timePicker;
    DatePicker的日期选择器;

    / **第一次创建活动时调用。 * /
    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.activity_main）;

        // ---按钮来查看---
        按钮btnOpen =（按钮）findViewById（R.id.btnSetAlarm）;
        btnOpen.setOnClickListener（新View.OnClickListener（）{

            公共无效的onClick（视图v）{
                timePicker =（TimePicker）findViewById（R.id.timePicker）;
                日期选择器=（DatePicker的）findViewById（R.id.date_picker_selected_date）;

                // ---使用AlarmManager触发警报---
                AlarmManager alarmManager =（AlarmManager）getSystemService（ALARM_SERVICE）;

                // ---获得当前的日期和时间---
                台历挂历= Calendar.getInstance（）;

                // ---设定闹钟时间触发---
                calendar.set（Calendar.YEAR，datePicker.getYear（））;
                calendar.set（Calendar.MONTH，datePicker.getMonth（））;
                calendar.set（Calendar.DAY_OF_MONTH，datePicker.getDayOfMonth（））;
                calendar.set（Calendar.HOUR_OF_DAY，timePicker.getCurrentHour（））;
                calendar.set（Calendar.MINUTE，timePicker.getCurrentMinute（））;
                calendar.set（Calendar.SECOND，0）;

                // --- PendingIntent启动活动时，报警触发---
                意图I =新的意向书（com.example.ltr_3.dtrem.DisplayNotification）;

                // ---指定为1的ID ---
                i.putExtra（NotifID，1）;

                PendingIntent displayIntent = PendingIntent.getActivity（
                        getBaseContext（），0，I，0）;

                // ---设置报警触发---
                alarmManager.set（AlarmManager.RTC_WAKEUP，
                        calendar.getTimeInMillis（），displayIntent）;
            }
        }）;
    }
}
