Question

这是我每天下午3点拨打电话的代码：

long INTERVAL_MSEC = 24 * 60 * 60 * 1000;

Date date2am = new java.util.Date();
date2am.setHours(15);
date2am.setMinutes(0);        

Timer timer = new Timer();
TimerTask task = new TimerTask() {
    public void run() {
        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        String finalPhonenumber = Globals.sms1PhoneNumbers.get(rad).number + getResources().getString(R.string.extention);
        callIntent.setData(Uri.parse("tel:" + finalPhonenumber));
        startActivity(callIntent);
    }
};

timer.scheduleAtFixedRate(task, date2am, INTERVAL_MSEC);

现在我需要每天上午12点到下午6点间隔60分钟打电话 - 我怎么能实现这个目标？

Answer 1

您需要创建一个在下午12点或00:00运行的警报：

 private void startat12() {
    AlarmManager alarmManager;
    alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Calendar c = Calendar.getInstance();
    c.set(Calendar.HOUR_OF_DAY, 00);
    c.set(Calendar.MINUTE, 00);

    Long milliseconds = c.getTimeInMillis();
    Long daily = 24L * 60L * 60L * 1000L;

    //check if the time is already passed
    if (milliseconds < System.currentTimeMillis()) {
        //if already passed then push it for next day by adding just 24 hrs
        milliseconds = milliseconds + daily;
    }
    Intent intent = new Intent(YourActivity.this, MyReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(YourActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, milliseconds, pendingIntent);
    } else {
        alarmManager.set(AlarmManager.RTC_WAKEUP, milliseconds, pendingIntent);
    }
    String dateFormat = "dd/MM/yyyy HH:mm";
    SimpleDateFormat formatter = new SimpleDateFormat(dateFormat);
    Toast.makeText(this, "Alarm is set for " + formatter.format(milliseconds), Toast.LENGTH_SHORT).show();
}

现在，您的MyReceiver将在第二天00:00收到广播您的接收器的代码将是：

public class MyReceiver extends BroadcastReceiver {

PowerManager powerManager;
PowerManager.WakeLock wakeLock;
AlarmManager alarmManager;
Calendar c;
SimpleDateFormat formatter;
String dateFormat;


@Override
public void onReceive(final Context context, Intent intent) {
    //acquire wake lock
    powerManager = (PowerManager) context.getSystemService(POWER_SERVICE);
    wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakelockTag");
    wakeLock.acquire();

    alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    c = Calendar.getInstance();
    c.set(Calendar.HOUR_OF_DAY, 12);
    c.set(Calendar.MINUTE, 00);
    Long daily = 24L * 60L * 60L * 1000L;
    //Set Unlocked notification broadcast
    Intent intentnew= new Intent(context, MyService.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intentnew, PendingIntent.FLAG_UPDATE_CURRENT);

    dateFormat = "dd/MM/yyyy HH:mm";
    formatter = new SimpleDateFormat(dateFormat);
    Toast.makeText(context, "Alarm is set for " + formatter.format(c.getTimeInMillis()+daily), Toast.LENGTH_SHORT).show();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, (c.getTimeInMillis() + daily), pendingIntent);
    } else {
        alarmManager.set(AlarmManager.RTC_WAKEUP, (c.getTimeInMillis() + daily), pendingIntent);
    }

    final Handler mHandler = new Handler();

    Runnable mRunnable = new Runnable() {
        @Override
        public void run() {
            //DO your Work for each Hour
            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            String finalPhonenumber = Globals.sms1PhoneNumbers.get(rad).number + context.getResources().getString(R.string.extention);
            callIntent.setData(Uri.parse("tel:" + finalPhonenumber));
            context.startActivity(callIntent);
            Toast.makeText(context, "It Ran", Toast.LENGTH_SHORT).show();
            //Also post your mHandler for next hour

            if (System.currentTimeMillis() < c.getTimeInMillis()) {
                mHandler.postDelayed(this, 60L * 60L * 1000L);
                Toast.makeText(context, "Task will repeat after an hour", Toast.LENGTH_SHORT).show();
            }

        }
    };

    c = Calendar.getInstance();
    c.set(Calendar.HOUR_OF_DAY, 18);
    c.set(Calendar.MINUTE, 00);
    mHandler.post(mRunnable);

    wakeLock.release();
}

}

并且在清单中包含唤醒锁定权限：

<uses-permission android:name="android.permission.WAKE_LOCK"/>

也是你的接收者：

<receiver android:name=".Notificationtwo.MyReceiver"/>

如何安排一些工作，每天上午12点到下午6点，在Android中间隔60分钟？
