notification新旧用法

api10版本以前 

protected void showNotification() {  
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);  

        Notification notification = new Notification(R.drawable.ic_launcher,"",System.currentTimeMillis() );  
        PendingIntent contentIndent = PendingIntent.getActivity(MainActivity.this, 0, new Intent(MainActivity.this,MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);  
        notification.setLatestEventInfo(MainActivity.this, "通知内容", "通知", contentIndent);  
        notificationManager.notify(id,notification);  
        
    } 

api10以后

protected void showNotification() {  
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
builder = new Notification.Builder(MainActivity.this); 
PendingIntent contentIndent = PendingIntent.getActivity(MainActivity.this, 0, new Intent(MainActivity.this,MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);  
builder.setContentIntent(contentIndent)
　.setSmallIcon(R.drawable.ic_launcher) //设置状态栏里面的图标（小图标） 
.setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.i5)) //下拉下拉列表里面的图标（大图标）
.setTicker("通知!") //设置状态栏的显示的信息  
       .setWhen(System.currentTimeMillis()) //设置时间发生时间  
       .setAutoCancel(true) //设置可以清除  
       .setContentTitle("title") //设置下拉列表里的标题  
       .setContentText("contenttext"); //设置上下文内容  
       Notification notification = builder.getNotification();  
　　　　 notificationManager.notify(id,notification);  
    }
