I have to do an app in wich i must set a date and at that specific date at 9 o'clock i must do a notification. What is the simplest method of doing that?(i want the app to work even if i reboot my phone, or take out my battery, is AlarmManager a solution?)

推荐答案

要正点，你可以使用AlarmeManager一个动作

To schedul an Action you can use the AlarmeManager

试试这个code这是为我工作：

Try this code it's work for me:

1 /声明BoradcastReceiver类启动操作，这个类可以在你的活动或境外在其他的java文件

1 / Declare the BoradcastReceiver CLASS to launch the Action, this class can be inside your activity or outside in an other java file

public class Receiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Toast.makeText(context, intent.getStringExtra("param"),Toast.LENGTH_SHORT).show();
    }

}

2 /在你的onCreate方法把这个code

2/ Inside your Oncreate Method put this code

AlarmManager alarms = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);

    Receiver receiver = new Receiver();
    IntentFilter filter = new IntentFilter("ALARM_ACTION");
    registerReceiver(receiver, filter);

    Intent intent = new Intent("ALARM_ACTION");
    intent.putExtra("param", "My scheduled action");
    PendingIntent operation = PendingIntent.getBroadcast(this, 0, intent, 0);
    // I choose 3s after the launch of my application
    alarms.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+3000, operation) ;   

启动应用程序举杯将出现在3秒后，所以，你可以改变System.currentTimeMillis的（）+ 3000你醒来的时间。

Launch your App a Toast will be appeared after 3 seconds, So you can change "System.currentTimeMillis()+3000" with your wake up time.
