在警报管理器中传递值

Question

我们怎样才能将值传递给接收者......我正在使用闹钟管理器...

Answer 1

使用PendingIntent，Intent已捆绑附加内容。

这是从AlarmController Google APIDemo：

修改的

Intent intent = new Intent(AlarmController.this, RepeatingAlarm.class);
intent.putExtra("some_name", some_value);
PendingIntent sender = PendingIntent.getBroadcast(AlarmController.this,0, intent, 0);

// We want the alarm to go off 30 seconds from now.
long firstTime = SystemClock.elapsedRealtime();
firstTime += 15*1000;

// Schedule the alarm!
AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,firstTime, 15*1000, sender);

然后检索接收者onReceive()中的那些：

intent.getStringExtra("some_name")
