如何使用广播接收器设置报警？是否有可能弹出一个消息比默认的消息？

其他指定的时间

解决方案

  AlarmManager ALR =（AlarmManager）this.getSystemService（ALARM_SERVICE）;
意向意图=新意图（YourAction）;
的PendingIntent的PendingIntent = PendingIntent.getBroadcast（背景下，0 / ** SOM唯一的ID * /，意向，0）;
alr.set（AlarmManager.ELAPSED_REALTIME，0 / **这里是一个延迟* /的PendingIntent）;
 

之后，你应该创建一个广播接收器，将获得与行动=YourAction意图。从接收器就可以启动，这将shoiw您与您的自定义消息对话框的活动。见<一href=\"http://stackoverflow.com/questions/4450347/how-to-lauch-an-3rd-application-automatically-when-the-android-phone-is-switched/4450405#4450405\">this答案，看看如何设置的广播接收器。

In my Android application I would like to set alarm at a particular time with some message for time entered by user.

How can I set alarm using broadcast receiver? Is it possible to pop up a message on the specified time other than the default message?

解决方案

AlarmManager alr =  (AlarmManager) this.getSystemService(ALARM_SERVICE);
Intent intent = new Intent("YourAction");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0/** som unique id*/, intent, 0);
alr.set(AlarmManager.ELAPSED_REALTIME, 0/** here is a delay*/, pendingIntent);

after that you should create a BroadcastReceiver, that will get intent with action = "YourAction". From that receiver you can start an activity which will shoiw you the dialog with your custom messages. See this answer to see how to setup the BroadcastReceiver.
