Android 之 Notification 通知消息

  
       NotificationManager是显示在手机状态栏的消息，如短息提醒等，做得大点，可以做消息推送等。下面的实例程序示范了如何通过NotificationManager来发送、取消Notification,本程序的界面很简单，只是包含了两个按钮，分别用于发送Notification和取消Notification，主要的java代码如下：

notification.java:

package com.example.notification;

import android.os.Bundle;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener{
	static final int NOTIFICATION_ID = 0x1123;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button b1=(Button)findViewById(R.id.b1);
        b1.setOnClickListener((View.OnClickListener) this);
        Button b2=(Button)findViewById(R.id.b2);
        b2.setOnClickListener((View.OnClickListener) this);
        
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    
	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch (v.getId()) {
		
		case R.id.b1:
			Intent intent = new Intent();
			intent.setClass(MainActivity.this, other.class);
			PendingIntent pi = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);
			Notification notify =  new Notification();
			notify.icon = R.drawable.no;
			notify.tickerText = "自己做的消息呀";
			notify.when = System.currentTimeMillis();
			notify.defaults = Notification.DEFAULT_ALL;
			notify.setLatestEventInfo(MainActivity.this, "站内信", "五一放假通知", pi);
			NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
			notificationManager.notify(NOTIFICATION_ID, notify);
			break;

		case R.id.b2:
			NotificationManager notificationmanager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
			notificationmanager.cancel(NOTIFICATION_ID);
			break;
		}
	}
}

other.java

package com.example.notification;

import android.app.Activity;
import android.os.Bundle;

public class other extends Activity
{

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.otherx);
 }
 }
