如何每天设置3次闹钟?

我想制作一个在特定时间调用意图的程序,早餐8点,午餐1点,每天6点半吃晚餐。

我该怎么做?这是因为如果我使用AlarmManager.INTERVAL_DAY / 3,则无法给出具体时间。

或者我可以使用其他课程吗?

这是我的代码:

package com.makansehat;

import java.util.Calendar;

import android.app.*;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
// import android.widget.EditText;
import android.widget.Toast;

/**

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void startAlert(View view) {
        Calendar skr = Calendar.getInstance();

        pagi.set(Calendar.HOUR_OF_DAY, 8);
        pagi.set(Calendar.MINUTE, 53);

        Calendar siang = Calendar.getInstance();

        siang.set(Calendar.HOUR_OF_DAY, 8);
        siang.set(Calendar.MINUTE, 55);

        Calendar malam = Calendar.getInstance();

        malam.set(Calendar.HOUR_OF_DAY, 8);
        malam.set(Calendar.MINUTE, 59);

        // EditText text = (EditText) findViewById(R.id.time);
        // int i = Integer.parseInt(text.getText().toString());

        Intent intent = new Intent(getApplicationContext(), MyBroadcastReceiver.class);
        PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, pagi.getTimeInMillis(), siang.getTimeInMillis(), pi);

    }

}

您应该创建3个警报:

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, pagi.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, siang.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, malam.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);

在这里,我附上Code以唤醒设备,准时在上午8:30准时发出警报,此后每20分钟发出一次警报:

private AlarmManager alarmMgr;
private PendingIntent alarmIntent;
...
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

// Set the alarm to start at 8:30 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 30);

// setRepeating() lets you specify a precise custom interval--in this case,
// 20 minutes.
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
        1000 * 60 * 20, alarmIntent);

我希望你能理解我能说什么只是设置你的第一次calander然后在手动使用for循环后给出间隔例如: 这里的时间表是触发警报的第二,第三等时间间隔小数

for(int i=0;i<timelist.size();i++){

      alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
            timelist[i], alarmIntent);
   }

或完成任务的第二种方式拿三个警报管理器并设定你的时间。

希望它能帮到你......
