我试图每天早上 9 点重复闹钟。但是闹钟没有在正确的时间重复，即，它只是在启动应用程序后显示吐司。为什么？

请提出建议！..

感谢您宝贵的时间。。

请找到我的参考资料

AndroidAlarmService.java

public class AndroidAlarmService extends Activity {

private PendingIntent pendingIntent;

@Override

public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 Intent myIntent = new Intent(AndroidAlarmService.this, RepeatingAlarm.class);
 pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0);

 AlarmManager aM = (AlarmManager)getSystemService(ALARM_SERVICE);

 Calendar c=Calendar.getInstance();
 c.set(Calendar.HOUR_OF_DAY, 9);
 c.set(Calendar.MINUTE, 0);
 c.set(Calendar.SECOND, 0);


 PendingIntent pi = PendingIntent.getService(getApplicationContext(), 0, new Intent(getApplicationContext(),AndroidAlarmService.class),PendingIntent.FLAG_UPDATE_CURRENT);
 aM.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY,pendingIntent);
 }
 }

重复警报.java

public class RepeatingAlarm extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {   
        Toast.makeText(context,"Alarm Started.....", Toast.LENGTH_LONG).show();

    // Vibrate the mobile phone
    Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    vibrator.vibrate(2000);

        }
    }

当您正在创建一个服务 PendingIntent 时，为什么不调用 BroadcastReceiver

public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 Intent myIntent = new Intent(AndroidAlarmService.this, RepeatingAlarm.class);
 pendingIntent = PendingIntent.getBroadcast(AndroidAlarmService.this, 0, myIntent, 0);

 AlarmManager aM = (AlarmManager)getSystemService(ALARM_SERVICE);

 Calendar c=Calendar.getInstance();
 c.set(Calendar.HOUR_OF_DAY, 9);
 c.set(Calendar.MINUTE, 0);
 c.set(Calendar.SECOND, 0);
 PendingIntent pi = PendingIntent.getService(getApplicationContext(), 0, new Intent(getApplicationContext(),AndroidAlarmService.class),PendingIntent.FLAG_UPDATE_CURRENT);
 aM.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY,pendingIntent);
 }
 }
