我正在设置警报但由于某种原因它们不再触发（即没有调用AlarmReceiver类）。
我用来设置闹钟的代码是：
public class SetMealTimersActivity extends Activity {
private static final int FLAG_UPDATE_CURRENT = 134217728;
PendingIntent pi, mealPI;
AlarmManager am;
@TargetApi(Build.VERSION_CODES.KITKAT)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_set_meal_timers);
am = (AlarmManager) (this.getSystemService(Context.ALARM_SERVICE));
// Get current date
Calendar cur_cal = new GregorianCalendar();
cur_cal.setTimeInMillis(System.currentTimeMillis());// set the current
// time and date for
// this calendar
// Set date for alarm from current date
Calendar cal = new GregorianCalendar();
cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
cal.set(Calendar.DATE, cur_cal.get(Calendar.DATE));
cal.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH));
long glbMealId = ((MealTimerApplication) this.getApplication())
.getMealId();
// Retrieve meal and store meal_ready_time
meal meal = new TableControllerMeal(this).readSingleRecord(glbMealId);
String meal_desc = meal.meal_desc;
int meal_ready_time = meal.meal_ready_time;
int meal_reminders_flag = meal.meal_reminders_flag;
// Set alarms for each item in meal plan
// Retrieve the meal plan for the meal
List<meal_plan> meal_plan = new TableControllerMealPlan(this)
.read(glbMealId);
if (meal_plan.size() > 0) {
int idx = 0;
for (meal_plan obj : meal_plan) {
long id = obj.id;
String mealItemDesc = obj.meal_plan_item_desc;
int mealItemStartTime = obj.meal_plan_item_start_time;
int mealItemDuration = obj.meal_plan_item_duration;
int startHours = mealItemStartTime / 60;
int startMinutes = mealItemStartTime % 60;
cal.set(Calendar.HOUR_OF_DAY, startHours);
cal.set(Calendar.MINUTE, startMinutes);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
Intent alarmIntent1 = new Intent(this, AlarmReceiver.class);
alarmIntent1.putExtra("meal_item_desc", mealItemDesc);
alarmIntent1.putExtra("meal_id", glbMealId);
alarmIntent1.setAction(Long.toString(id)); // Makes intent unique to prevent one notification overwriting another
idx++;
pi = PendingIntent.getBroadcast(this, idx, alarmIntent1,
FLAG_UPDATE_CURRENT);
am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
if (Utilities.getAPIVerison()<4.4){
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);
} else {
am.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);
}
}
}
//Create notification to indicate that Alarms have been set
PendingIntent contentIntent;
contentIntent = PendingIntent.getActivity(SetMealTimersActivity.this, 0,
new Intent(SetMealTimersActivity.this, MainActivity.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(SetMealTimersActivity.this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Meal timer notification")
.setContentText("Reminders Pending");
mBuilder.setContentIntent(contentIntent);
mBuilder.setSound(null, 0);
mBuilder.setAutoCancel(true);
Notification myNotification = mBuilder.build();
NotificationManager mNotificationManager =
(NotificationManager) SetMealTimersActivity.this.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(111, myNotification);
Toast.makeText(this, "Reminders Set", Toast.LENGTH_SHORT).show();
finish();
}
我在AndroidManifest中声明了闹钟接收器：
<receiver android:name="com.ian.mealtimer.AlarmReceiver" >
</receiver>
...这里是AlarmReceiver类：
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String mealItem = intent.getStringExtra("meal_item_desc");
int actionId = Integer.parseInt(intent.getAction());
//If this is the final notification reminder for this meal then cancel the "Reminders Pending" notification
String mealReadyNotification = context.getResources().getString(R.string.meal_ready_notification);
if (mealItem.contains(mealReadyNotification)) {
NotificationManager mNotificationManager1 =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
//First cancel the original Quick Timer notification
mNotificationManager1.cancel(111);
}
//Get user preferences
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Boolean vibrate = sharedPrefs.getBoolean("notifications_new_message_vibrate", false);
String notifSound = sharedPrefs.getString("notifications_new_message_ringtone", "");
Toast.makeText(context, "Meal Timer: " + mealItem, Toast.LENGTH_LONG).show();
PendingIntent contentIntent;
//Take the user to the MealItemActivity after selecting the notification
contentIntent = PendingIntent.getActivity(context, actionId,
new Intent(context, MealItemActivity.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Meal timer notification")
.setContentText(mealItem);
mBuilder.setContentIntent(contentIntent);
mBuilder.setSound(null, 0);
mBuilder.setSound(Uri.parse(notifSound));
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(actionId, mBuilder.build());
// Vibrate the mobile phone if option is set in preferences
if (vibrate) {
Vibrator vibrator = (Vibrator) context
.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(2000);
}
}
}
任何想法我做错了什么？
答案 0 :(得分：0)
卫生署！我刚发现问题 - 这行应该是cal.set，而不是cal.add：
cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
