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);
             //定义Notification的各种属性
             int statusBarIcon = android.R.drawable.stat_sys_download;//现在在状态栏中的图片id
             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_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
             //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;
             if(progress.contains("100%")) {
                 LogUtil.i(tag, "progress2=" + progress);
                 content = "下载完成，点击安装！";
             }
             RemoteViews contentView = new RemoteViews(context.getPackageName(),R.layout.lx_view);
             contentView.setImageViewResource(R.id.image,android.R.drawable.stat_sys_download);
             contentView.setTextViewText(R.id.text01, title);
             contentView.setTextViewText(R.id.text02, content);
             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();

                 intent.setAction(InstallApkService.class.getName() + notificationId);
             }
             PendingIntent pendingIntent = PendingIntent.getService(
                     context,
                     0, //发送者的请求码（可以填0）
