}
}

尝试先使用广播接收，然后启动服务。

像这样的东西：

创建一个函数：

public static void setRecurringAlarm(Context context, Class<?> cls, int time, int minute) {
    Calendar updateTime = Calendar.getInstance();
    updateTime.setTimeZone(TimeZone.getDefault());
    updateTime.set(Calendar.HOUR_OF_DAY, time);
    updateTime.set(Calendar.MINUTE, minute);

    Intent alarm = new Intent(context, cls);
    PendingIntent recurringAlarm = PendingIntent.getBroadcast(context, 654789, alarm, PendingIntent.FLAG_CANCEL_CURRENT);

    AlarmManager alarms = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
    alarms.setRepeating(AlarmManager.RTC_WAKEUP, updateTime.getTimeInMillis(), AlarmManager.INTERVAL_DAY, recurringAlarm);
}

如果您不想设置重复警报，只需将 setRepeating 更改为 set。

在您的代码中，您需要调用：

// to start the receiver at 9:00am
setRecurringAlarm(this, AlarmManagerReceiver.class, 9, 0);

因此，您需要创建 AlarmManagerReceiver.java：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class AlarmManagerReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent alarmService = new Intent(context, AlarmManagerService.class);
        context.startService(alarmService);     
    }

}

现在，您需要以下服务：

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.IBinder;
import android.preference.PreferenceManager;

public class AlarmManagerService extends Service {

    private Context context;

    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();

        context = this.getApplicationContext();
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);

                // Do what you need to do.

        stopSelf();
    }
}

在清单中：

<receiver android:name=".AlarmManagerReceiver" >
        <intent-filter>
            <action android:name=".AlarmManagerReceiver" />
        </intent-filter>
</receiver>
<service
    android:name=".AlarmManagerService"
    android:enabled="true" >
    <intent-filter>
        <action android:name=".AlarmManagerService" />
    </intent-filter>
</service>
