如何安排一些工作，每天上午12点到下午6点，在安卓系统中以60分钟的时间间隔进行工作？

Question

这是我每天都在打电话，在下午3点代码：

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); 

现在我需要到下午6点进行60分钟间隔上午12点之间的呼叫每天 - 我怎样才能做到这一点？

Answer 1

您需要创建如下创建警报运行在12日上午：00：00小时：

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(); 
} 

现在你MyReceiver将在次日00:00时 的代码接收广播您的接收器将是：

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(); 
} 

}

，做包括唤醒锁的许可，您的清单：

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

还接收机：

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