我试图写一个code有事时激活报警。我想过使用默认的报警及消防它，当我考虑，但首先我不知道如何来触发报警或处理。第二：我不知道是否有火灾立即报警，听起来并告诉用户一个消息的最简单的方法

I'm trying to write a code that activates an alarm when something happens. I've thought on using the default alarm and fire it when I consider it, but first: I don't know how to fire the alarm or handle it. Second: I don't know if there is an easiest way to fire an immediate alarm that sounds and tells the user a message.

例如：

（真）   火灾声音报警，提示信息提醒用户其他   其他一些code

if (true) Fire an audible alarm with a message to advise the user else Some other code

感谢您的帮助。

推荐答案

AlarmManager：

AlarmManager:

public void startAlert() { Intent intent = new Intent(this, MyBroadcastReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast( this.getApplicationContext(), 234324243, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (i * 1000), pendingIntent); Toast.makeText(this, "Alarm set in " + i + " seconds", Toast.LENGTH_LONG).show(); }

广播接收器：

public class MyBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Don't panik but your time is up!!!!.", Toast.LENGTH_LONG).show(); // Vibrate the mobile phone Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE); vibrator.vibrate(2000); } }
