稍後執行的意圖

1. 建立一個接收器。該類將收到意圖並按你的意願處理。

public class AlarmReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        // Handle intent
        int reqCode = intent.getExtras().getInt("requestCode");
        ...
    }
}

2. 給出 AlarmManager 的意圖。此示例將觸發 1 分鐘後傳送到 AlarmReceiver 的意圖。

final int requestCode = 1337;
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, requestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.set( AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 60000 , pendingIntent );
