設置AlarmManager時間onClick android

-1

我試圖改變AlarmManager的時間爲1天，3天和7天點擊相應的按鈕。例如，如果我點擊「1天」按鈕，鬧鐘應該設置爲每天重複的方式等等。但我不知道如何實現這一點，我有預先定義的時間重複報警的代碼設置AlarmManager時間onClick android

public class MainActivity extends Activity { 

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

     Intent intent = new Intent(this, NotifyService.class); 
     PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 
       PendingIntent.FLAG_CANCEL_CURRENT); 
     AlarmManager am = (AlarmManager) this 
       .getSystemService(Context.ALARM_SERVICE); 
     long recurring = (1 * 60000 * 60 * 24); // repeat every 24 hrs 
     am.setRepeating(AlarmManager.RTC, Calendar.getInstance() 
       .getTimeInMillis(), recurring, sender); 
    } 

    public void set1day(View view) { 
     //... 
    } 

    public void set3days(View view) { 
     //... 
    } 

    public void set7days(View view) { 
     //... 
    } 
}

有間隔日可用的默認常量。您應該使用它們而不是計算間隔的秒數。像這樣的：

爲單天的間隔

public void set1day(View view) {  
    am.setInexactRepeating(AlarmManager.RTC, Calendar.getInstance() 
       .getTimeInMillis(), AlarmManager.INTERVAL_DAY, sender); 
}

3天間隔

public void set3day(View view) { 
    am.setInexactRepeating(AlarmManager.RTC, Calendar.getInstance() 
       .getTimeInMillis(), AlarmManager.INTERVAL_DAY*3, sender); 
}

對於任何n天間隔

am.setInexactRepeating(AlarmManager.RTC, Calendar.getInstance() 
      .getTimeInMillis(), AlarmManager.INTERVAL_DAY*n, sender);

另外，作爲API 19，所有重複警報不準確。使用setInexactRepeating以避免電池耗盡。
