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);
            }
        });
    }

解决方案

尝试以下链接它可以帮助你。

使用报警管理器调用该服务。

唐,别忘了拨打服务机器人的manifest.xml
