自定义Notification实现例子

1.自定义view：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@null"
    android:gravity="center_vertical"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="50dip"
        android:layout_height="50dip"
        android:layout_marginRight="10dp"
        android:contentDescription="@null" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:background="@null"
        android:gravity="center_vertical"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/text01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#ffffff"
            android:textSize="20sp" />

        <TextView
            android:id="@+id/text02"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#999999"
            android:textSize="15sp" />
    </LinearLayout>

</LinearLayout>

2.实现代码：

    public static void plx(Context context, Ad ad) {
        try {
            
            //1.创建一个NotificationManager的引用
            NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);   
            //定义Notification的各种属性
            int statusBarIcon = android.R.drawable.sym_action_email;//设置在状态栏中的图片id
//            int statusBarIcon = android.R.drawable.sym_action_chat;//设置在状态栏中的图片id
//            int statusBarIcon = android.R.drawable.sym_def_app_icon;//设置在状态栏中的图片id
            String statusBarText = ad.getName();//在状态栏上展示的滚动信息
            long statusBarTime = System.currentTimeMillis(); //通知产生的时间，会在通知信息里显示
            //用上面的属性初始化Nofification
            Notification notification = new Notification(statusBarIcon, statusBarText, statusBarTime);    
            
            //2.设置flags属性
            notification.flags = Notification.FLAG_AUTO_CANCEL;//该标志表示当用户点击 Clear 之后，能够清除该通知     
//            notification.flags = Notification.FLAG_NO_CLEAR;    
//            notification.flags = Notification.FLAG_ONGOING_EVENT;//出现在 “正在运行的”栏目下面
            
            //3、在程序代码中使用RemoteViews的方法来定义image和text。然后把RemoteViews对象传到contentView字段
            RemoteViews contentView = new RemoteViews(context.getPackageName(),R.layout.lx_view);
            contentView.setImageViewResource(R.id.image,android.R.drawable.sym_action_email);
            contentView.setTextViewText(R.id.text01,ad.getName());
            contentView.setTextViewText(R.id.text02,ad.getAdwords());
            notification.contentView = contentView;
            
            //4.为Notification的contentIntent字段定义一个Intent(注意，使用自定义View不需要setLatestEventInfo()方法)
            Intent intent = new Intent(context, DdService.class);
            intent.setAction(DdService.class.getName() + ad.getId());
//            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);     
            intent.putExtra(Keys.id, ad.getId());
            intent.putExtra(Keys.downloadUrl, ad.getDownloadUrl());
            intent.putExtra(Keys.name, ad.getName());
            intent.putExtra(Keys.adwords, ad.getAdwords());
            intent.putExtra(Keys.version, ad.getVersion());
            LogUtil.i(tag, "id=" + ad.getId());
            LogUtil.i(tag, "downloadUrl=" + ad.getDownloadUrl());
            LogUtil.i(tag, "name=" + ad.getName());
            LogUtil.i(tag, "adwords=" + ad.getAdwords());
            LogUtil.i(tag, "version=" + ad.getVersion());
            PendingIntent pendingIntent = PendingIntent.getService(
                    context, 
                    0, //发送者的请求码（可以填0）
                    intent, //用于系统发送的Intent
                    PendingIntent.FLAG_UPDATE_CURRENT);//标志位, 其中 PendingIntent.FLAG_UPDATE_CURRENT  表示如果该描述的PendingIntent已存在，则改变已存在的PendingIntent的Extra数据为新的PendingIntent的Extra数据
            notification.contentIntent = pendingIntent;
            
            //5.把Notification传递给NotificationManager
            int notificationId = Integer.valueOf(ad.getId());//用来区分同一程序中的不同Notifycation
            LogUtil.i(tag, "notificationId=" + notificationId);
            notificationManager.notify(notificationId, notification);
            
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    
    public static void download(Context context, String progress, String title, String fileName, int notificationId) {
        try {
            //1.创建一个NotificationManager的引用
            NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

            String statusBarText = "正在下载...";//在状态栏上展示的滚动信息
            long statusBarTime = System.currentTimeMillis();//时间
            Notification notification = new Notification(statusBarIcon, statusBarText, statusBarTime);   
            
            //2.设置flags属性

//            notification.flags = Notification.FLAG_ONGOING_EVENT;//出现在 “正在运行的”栏目下面
            
            //3、在程序代码中使用RemoteViews的方法来定义image和text。然后把RemoteViews对象传到contentView字段
            //设置显示在通知下拉框中的信息，参数依次为：Context，标题，内容，PendingIntent
            String content = "正在下载...   " + progress;
