/* 注意：建立完BroadcastReceiver後，需要在AndroidManifest.xml中註冊：

        2.3 提醒功能
新建一個Activity，我們在這個Activity中通過Android的Notification物件來提醒使用者。我們將新增提示音,一個TextView來顯示提示內容和並一個button來取消提醒。

其中，建立Notification主要包括：

        1）獲得系統級得服務NotificationManager，通過 Context.getSystemService(NOTIFICATION_SERVICE)獲得。

        2）例項化Notification物件，並設定各種我們需要的屬性，比如:設定聲音。

        3）呼叫NotificationManager的notify()方法顯示Notification

詳細程式碼如下：MyAlarm.java

package com.Reminder;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore.Audio;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

*//**
 * Display the alarm information
 *//*
public class MyAlarm extends Activity {

    *//**
     * An identifier for this notification unique within your application
     *//*
    public static final int NOTIFICATION_ID=1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_alarm);

        // create the instance of NotificationManager
        final NotificationManager nm=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        // create the instance of Notification
        Notification n=new Notification();
    *//* set the sound of the alarm. There are two way of setting the sound *//*
        // n.sound=Uri.parse("file:///sdcard/alarm.mp3");
        n.sound= Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "20");
        // Post a notification to be shown in the status bar
        nm.notify(NOTIFICATION_ID, n);

    *//* display some information *//*
        TextView tv=(TextView)findViewById(R.id.tvNotification);
        tv.setText("Hello, it's time to bla bla...");

    *//* the button by which you can cancel the alarm *//*
        Button btnCancel=(Button)findViewById(R.id.btnCancel);
        btnCancel.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                nm.cancel(NOTIFICATION_ID);
                finish();
            }
        });
    }
